I'll take the stock intake w/53 hp curve myself.

Very sweet build! Nicely done Chad.

thanks ghott!



here is the A/Fr

again,....

RED= FCI intake

BLUE= stock with DRG filter


look how flat of a response the A/Fr is with the stock box with DRG filter setup... shows my ignition curves are ballz on too!!

[wppracing]

Looks good:)

Do you have a graph with the HP and TQ together?

FCI 54.17hp / 32.16tq
Stock 52.94hp / 32.34tq

[wppracing]

The FCI has one wavey A/F line.

What were the mods done in this build?

yes brian if you want to look at the pk numbers, I should have compared the best hp and tq from each setup. the stock box with DRG filter hp run pulled consistently mid 53's...

[chad502ex]

pictures posted tonight...

[wppracing]

With the smoother curve the stock box set up has, I would stay with that one.

the only difference between the wavy A/F response of the "FCI setup" to the "stock box with DRG filter setup" was just the change in intake boot setup. No jetting change was required. The FCI did come with their FCI intake filter as pictured earlier in this thread... Also, we swapped the FCI intake filter that is supplied with the kit, with another 'custom' inverted cone type filter of the same filter manufacture to see if there was a difference in power or response. The inverted cone filter exchange made no significance change in power or A/Fr..

pictures of the inverted cone filter on the FCI will also be posted..

LOL!

I'm not trying to brag about 'going big-time'. There are already a few credentials that are doing real well on the race circuit.

Here are a few of the racers build(s) that I am very proud of:

czrider263
kilabanshee
mike nash
jasson450R

Pro
Michael Ouel (Canada)
Daryl Rath (just carb)


all of which have wins and holeshots week after week....





I'm just happy that they are happy.

forrest gump?


ha, anyways sick build chad. Your one lucky SOB czrider, hope you have some serious fun on that thing. That tq curve is absolutely amazing.:eek2:

[Kilabanshee]

Well it looks like my quess was on the money. I based it off the power I made at Breezewoods. I knew Alex "czrider263" was running the web 208/921 cam and that was good for atleast another 2-3hp on top of what I have. Other then that me and Alex have basically the same exact motor. I believe I made 52hp and 32lbs of torque.

[czrider263]

Great Numbers chad can't wait till sat to pick it up and ride the beast. I WON"T BE ABLE TO SLEEP TONIGHT.


Well i can't wait to retest after a small purchase of a DASA pipe!! lol

Can you say Rossier for sale!?

[FurryJello]

I would like to thank Chad and czrider263 for documenting this build. It has been very entertaining.

[Hammer trx450r]

Wow chad u did it again. That thing is gonna be a handfull. Congrates and good luck with your new job;)

[MR.BIG]

I have a question? What is the loss between the motor and the rear wheels? I know a car is like a 22% loss through the driveline I was wondering what power this machine is making at the motor.

typically about 15-20% loss through an ATV drive-train.

dirt bikes are signifcantly less because of the less rotational mass to turn... think about the difference the quad has with the axle, hubs, tires and rims, brake rotors, ect all taking the power away...

ever feel how light the RPM billet drag axle is in comparison to the stock/aftermarket MX axle?

[Nick110]

Czrider I want what ever job you have that allows u to have 3 sick quads.


Nice build chad. You will be getting some stuff from me sometime. But suspension comes first.

[chad502ex]

thanks everyone again for your great comments.

Unless there are no more questions to answer about this build, I'll be sitting back and listening for czrider263 'response to his ride report. czrider263 just picked his new monster up tonight. I gave him instruction, his old parts, his new spare parts and a CD that blueprinted his entire build to every detail.. Many pictures and info that i couldn't even have time to upload too!!.

[czrider263]

Yup I did pick up the beast! Can't wait to ride it!

[the predator]

is there an advatage from the 2 ring piston to the 3 ring besides weight and friciton mass?

i will be doing a piston swap this winter and have been wondering.

[quadking224]

sux we couldnt ride it today koz, guess it jus wasnt the right time yet!!!lol..ne way..yo ill b around tom if ya wanna continue the track build for the new beast...awesome job on the build chad...im likin the RED DRG haha...the ltr had some nice pull tho with the arrestor out and the cherry bomb on it koz...peace

[eastside 400]

y arent u racing sleepy tomorrow? u got your cards and 2 quads now so no excuses

Na he has 3 now.

[TMSmx47]

Dude no way.. I was so plannin on runnin this DRG build tomorrow and now he's flakin out! I hope this isn't true cz.. Chads waitin for some feedback here to my man!

[Kilabanshee]

Alex I'll be at Rausch today with the boys. I was going to race sleepy but after watching a video of the layout I wasn't the least bit impressed. Does anyone have any more recent video or pictures of sleepy hollow? Chad I'll be getting some video of the tripple I promised you. Maybe I'll even quad it today....:eek: :devil:

Dude you have no idea how much i want to race. They weren't even going to give me a card for this year, but i talked them into it. But the deal was that i couldn't race till after the 25th of sept. So after that i will race every race i can trust me.

[quadking224]

yo koz...we better get on it then...theres 2 weeks till u can race...its gonna be sick man....u need to get a feel for the 06 tho bf we go racein and not when we get there...u gotta kno how its gonna react or well get no where..gonna be over soon to ride..well take some pics of the 06 in action soon...Koz 161 look out for him hes smokin fast man..dont wanna mess with him either!

Ride report:

Well after intalling a 14tooth sproket this thing is uncontrolable. Out of every corner this thing wheelies like nothing else. No matter what RPM and you pin it, it wants to pull your arms off. As soon as i get the suspension tuned in this thing will be a real racer. GREAT JOB CHAD your the #1 motor builder in my eyes. Not only do your motors put it down on the dyno you show all the work you put into it and show you exactly what went into your build. AWSOME CHAD!!!

[chad502ex]

WOW, kewl video and pics...

thanks.:macho

[mike nash]

Chad,I have to complain about my DRG TWIN.
There is so much power on tap that my gloves are worn through each race from holding on for dear life.
Now I need a glove sponsor:grr:

[chad502ex]

i've been thinking.... oh no!

I found new technology from my day job as an electrical RF engineer that uses microwave frequency technology to cut-off unwanted frequency bands...

It gave me another tangent addition for my build...

Of corse!

[TMSmx47]

By all means CZ, Im def not knockin you for not racin. Sorry it kinda seemed like I came off that way. Hopefully we'll see you at Sleepys last race of the season on Oct 8th.. Im just really excited to see the bike and this motor in person. My head from my 04 is goin to Chad anyway for next season.. DRG Power!

PS Nice vids!;)

[czrider263]

I WILL BE RACING NOT THIS WEEKEND BUT THE ONE AFTER THAT!!!. I got the number plates on it now pics soon.

[chad502ex]

I usually try not to ask of ppl that enjoy my threads, but for all that followed this build and found it interesting or a learning experience please take a moment and PM ADMIN and tell him so..

hehe.

wow- over 10,000 views...

:cool:

[czrider263]

I told you the exriders members would love it!!! thats why i told you to put it on this site for all to injoy. I mean 10,000 views don't lie! Well here are the finished pictures of it ready to go racing. check out the custum graphics O YEAH.

[exrider008]

that is so sick!!! i love the sound of that pipe too.:eek2:

[eastside 400]

whats your 3rd quad now?

[Jersey450R]

I just hope the motor makes it through a race ;)

[czrider263]

it will!!!

Chad ps.. after an hour runtime do you think i should other than change the oil check the vavle clearences.

I was kidding btw :p I'de change it just for good measure. the 1st ride has got to stir up some change:D .

Jersey

[chad502ex]

sure. check those hot cam shims on the intake side when you check the valve lash. I'm worried for you that the HC shims won't take that much beating abuse from the DLC Ti valve tips pounding the shims thickness into pancakes... PM me when you get those measurements...

[chad502ex]

Hey ppl. Nobody suggested anything about the power above 9400, so i thought i'd point it out further from the attached dyno plot...

look over the torque graph below where the run is stopped purposely at 9400 rpm (due to the build being a customers),.... now, extend the torque line over from 9400 to 10000 rpm,..... you get ~29lb/ft. of torque at 10k.

mathmatically, the dyno formulates the following:

HP = tq x rpm/5250

HP = 55.24


Here's your 55hp stock bore...... thanks for asking. :D

maybe i should have rolled the dice and rev'd higher, huh? naaaa- I knew what the engine had!

[chad502ex]

futhermore, I feel I should extend a shout-out to the parts vendors for this buildup:

Falicon
KibbleWhite
Web camshafts
DASA
Baldwin
Dynatek
Tiny Tach

[Chino886]

This may be a stupid question, but what model of Tiny Tach did you use?

[chad502ex]

Originally posted by Chino886

commercial version... works great for engine logging...

[czrider263]

Dasa pipe is ordered!!! we need to dyno again and go to 10,000 lol.

[chad502ex]

you can dyno if you wish. I don't want to dyno anymore unless i have too on my setup....


:D

[czrider263]

Im not asking you to dyno it but i wouldn't mind if you where there to offer support and see your beast pump out big numbers.

no biggie.

[Jonas]

Are you going to shootout the Dasa and Rossier on your setup CZ? If so, I am tuning in for that graph. I haven't seen anyone shootout them on the '06 or '07.

[Architects]

Sick bike!!

not a bad idea...;)

[czrider263]

Sounds like a plan. everything will be the same but the day and the pipe.

ps chad do you think that will change my jetting?

[chad502ex]

possible jetting could change if the pull on the cylinder gasses changes....

[chad502ex]

hey czrider263, are you racing this weekend? just wondering... please keep us informed...



Oh, and I've named my next generation head...

It'll be called a DRG DSAR

I'll be explaining what DSAR acronym implies real soon...

dual stage ...... ..... technology

;)

[lumi]

hey guys are i think this is one of the best setups and step by step build i ever saw on the internet, you guys thinking of putting this up on other site that would be awesome for other people to see the great work, time, you guys put into the motor o and why is this not a sticky?

Well on the sech there are no racing for this weekend BUMMER.....

so i will take this weekend to dial in the 06 for next WAHOO.


And yes i had a great birthday.


Sold the rossier to make room for the DASA which is coming this week.
Check out the pipe the guy who bought it is getting after i polished it up for him.LOL A little present for beany

yo man gonna be sweet..sux it aint this weekend..but i am still working on that proj. to get u some dirt from my neighbor....i am also talkin wit tommy organski for T. Organski Excavating where i work part time in the summer to see if he can hook me up with some to build a sick freestyle jump to practice big air trcks an all...b talkin to ya bout that this week.....Go DRG #161


Ur either first or ur last!! I lived my whole life by that!! son i was high when i said that!!

[czrider263]

HAHAHAHAHAHAHA Its true with my motor ill either be out front or broken down in the pits..... lets hope the second one doesn't happen!!!

BTW want to get a HCS3 for the build and test that against my 208......Chad you did say that cam is a little safer right???

[chad502ex]

sure the HC3 will give you more piston-to-valve clearances due to the HC3 having less overlap than the 208. +

Actually, the HC3 has more valve lift than the 208, but because the lobe centers are pushed away from TDC, and also because the ramp is not as drastic as the 208, the cam is not a potentially destructive as the 208. IMO, the 208 should deliver more power because of the quick acceleration of the valve openings helps to accentuates the signaling on the carb fuel circuit(s).


Are you wanting your build to end up being a dyno mule or a race rocket?:confused: just install that DASA pipe and cam and go win some races....

[czrider263]

Got the DASA pipe installed!!! let me go snap some pics....

[czrider263]

Here we go.....check out this sweet pipe.

love the second pic.


let the dyno mule take stall. lol.

[czrider263]

I want to get it dynoed again with the DASA and let it go to 10,000rpm. also i want to test the 208 vs. the HCS2 if that guy will sell it to me.

[Kilabanshee]

Looking good Alex. Can't wait to do some upgrades to mine over this winter. I'm looking into a Titanium shock rebuild, new frame, nerfs, and maybe something alittle extra from Chad.:devil: :devil:

lol don't bash me!!!

I just rode the 450 with the dasa and it seems to crack up high is that the main? i will throw it on a dyno soon. what do you think chad.

[beany]

Chad the RE is in my garage now so the shootout if you come and get my quad from Michigan???

And czrider got the pipe today couldnt wait to get home from workto see it, you did a hell of a job cleaning that thing up!!! Thanks again!

Whats a good starting point with the jetting '06 stock other then the RE pipe and Unii filter?? Up two sizes on the main and work from there???

[Kilabanshee]

You should be around 170-180 main with those mods.....

[chad502ex]

its over my head! hehe.

[beany]

Chad I sure hope that its not!!! I've looked at all the work that you've done and I am truely impressed! Wish I had the talent to do the things that you probably take for granted now!

thanks, but i was only kidding.

i have to admit jetting is not my strength. Its way too easy for me to dyno and see for sure instead of performing the 5 second WOT run checking the plug with the chance of being to lean and melting the build down.... Because I've done so many I'm getting closer to estimating.

beany- go with Kilas recommendation.

czrider263- cracking with DASA pipe, what do you mean cracking? are you talking about a studder or bobble?

Is your lid on or off?

[beany]

Lid is still on.
Was thinking on getting the HRC kit and using the stuff I needed out of it, like the cam and jets and lid but not to sure yet??

Czrider been working to much so its not on yet, need to get the jets to maybe this weekend?? but not sure

[Jonas]

If you have a full exhaust you should definately not get the HRC kit. Hot cam stage II, an '04 CRF needle, CRF250r leak jet, and a $3.50 main is all you need. All for less than $200. The rest of the kit you can easily duplicate. Taking your lid off with this combo will make a huge difference on throttle response and change the jetting spec ofcoarse.

[chad502ex]

eed to go up one or two sizes though..

[beany]

Was thinking the HRC kit for the warranty issues. I have the 4 year warranty so kinda wanted to stay with the honda internals, Could just sell off the stuff I don't need on here or ebay, some people think their getting a deal just because its on ebay!!! Sell the exhaust stuff and harness and just cut the wire. Figure I might be able to get around $100-150 on ebay for that stuff , but we'll see. Been working to much to do anything with my wheeler lately. So that sucks

[Kilabanshee]

I'll be at Rausch Tomarrow. I'll c-ya there Alex. Do you still have my cell phone number? We'll be taking some more video just remember to remind me so chad doesn't get on my arse!:devil:

[czrider263]

ahhh can u make it sunday?


idk ill prob make sat idk

[czrider263]

Race on the 8th sleepy hollow!!!

[czrider263]

Ok chad need your jetting skills.

After getting the tiny tach to work again i did some runs on the dasa. reving it out it only hit 7,024rpm. so what do you think i should do with jetting?

[chad502ex]

sounds way too fat and its bobbling on itself. go back to your orginal jetting, then PM me the results...

[czrider263]

Iv tried many jets from 183 to 195 with no luck getting rid of the bobble, so today my dad is taking it to a dyno with a A/F tester to finally get it jetted correctly. the hp numbers won't mean anything though because of it not being the same dyno.

true about the numbers, especially in this incliment weather.... but anyway, I hope that dyno operator knows what he is doing and don't destroy your engine....

Put the 183 in and take the lid off the airbox, If it gets better with no lid then u need to go to about 175, if it gets worse with no lid than u need a 200-210


My money is on you are too rich just my 02, 183 to 195 is fine tunning u need more drastic change

Chad what happened here that his jetting is off? Is it just an exhaust change?

[chad502ex]

the scavening across the piston to the carb using the DASA should be much greater thus requiring signifantly less jetting that what is needed with the RE. 183 may not be small enough.. could be about 170 with the pull of the DASA exhaust.

Jetting guessing is why i dyno.

[mike nash]

Hey my build was pretty close to what you have and Chad had me @ a 178 with K&N powerlid.

Yeah i tried to explane that to my dad about making more power but a smaller jet. will have results tomorrw. im pretty sure its going to be in the 170's but a A/F graph will tell the story. with your 10,000rpm limit i hope it goes well.

[beany]

Czrider putting the pipe on as we speak, steppinf up on the main from a 120 to a 125, hopeing that it will work thought it was a 115 in there stock but i was wrong, see if i can get it running right tonight, with the pipe and the uni filter. First time wish me luck

[czrider263]

i would start higher than a 125 go to a 180 to be safe.

[czrider263]

Ok got the bike back from the dyno....

that being said the jetting is very nice and can't wait to race tom...

don't compare the hp and tourqe numbers they are way off we were going for the A/F graph. like tha temp, and humidity were different, ran noby tires and didn't take off the rear brake and ran in 4th gear.

heres the before. notice how bad the A/F graph is
http://i21.photobucket.com/albums/b292/czrider263/06drg/dyno1.jpg

after see how much smoother it is.

[mike nash]

Well,what did you end up with for jetting?

[chad502ex]

this is just terrible. If you race with the second dyno curve jetting settings you'll get stomped. lost all your low end to 8000 rpm.

TAKE YOUR QUAD BACK AND GET YOUR DYNO MONEY BACK!

Those guys fudged up the jetting sooo bad... clearly they have no clue how to dial in a setup. WTF! They killed the power from 5250 to 8500! WTF!!!

Didn't you compare the first curve power from 5250 to 8000 to the second before you left the dyno? :mad:

This was an engine making over 54hp+, dialed in perfect and now it just pisses me off.

look at the first A/Fr on the first graph you posted... see the spike at 5500 rpm? That is normal and very typical.... It is caused from the instant wide open throttle response when the dyno operator stabs the throttle for the dyno pull... Imagine when the operator stabs the throttle, the FCR slide pulls up instantly, the engine 'gulps' in max air, a little fuel, which causes the lean response,..... then, the acellerator pump squirts in the fuel and washes the A/Fr response down to normal to about 7000 rpm...


Please, put your jetting back to what it was before they blow your build up....:grr:

[Jonas]

Hey, if I was the dyno operator I would probably get a little nervous putting those graphs together on the same graph also:D 5-7 horsepower loss in the mid range??? Forget about the air/fuel curve and pay attention to that horsepower curve, it will tell you the real story.

[czrider263]

Well even with the A/F that way i had a great race today if it wasn't for the flagers!!!!!:mad:

WIll post more pics later and the holshot vid


ONCE AGAIN THANKS CHAD THIS MOTOR KILLED EVERYONE!!!

[czrider263]

Well even with the A/F like that i still had a great race today.

If it wasn't for the flagers!!!!


Well once again thanks chad this motor made the race possible for me!!!

:macho

[Kilabanshee]

What did you end up placing Alex and in what class?

[TMSmx47]

Alex ended up 4th overall in 450 C... His first time there!!

[czrider263]

yeah it took a while to get used to that track lots of doubles and rythem sections. it was fun should have gotton 1st but two people passed me during yellow flag and they wouldn't chage it so i ended up with 4th.....o well i got the HOLSHOT WAHOOOOOO. thats the first one I have every pulled.

Thanks chad.

[Kilabanshee]

Yeah.... Rausch finally installed their watering system. It's a pretty nice set up they just ran it way to long. There were a few spots on the track which began to form little mud pits. They also fixed the lip on almost all the jumps.

[chad502ex]

I should be thanking you, kila, and mike. If it were not for you three, were would I be today? LOL!

WTG!

Yellow backrounds are used by C riders in ATVA National Series. B is red, PRO is obviously blue, and PRO-AM is black, think A is white... or vise-versa A and PRO-AM..

[mike nash]

Chad, I was @Rausch yesterday and I had to stop a few times to check my tires cause my machine has so much torque it felt like they were being ripped off the rims(good thing I have Hipers). Like dragster tires.

OH MY!!:eek2:

LOL

[czrider263]

Will post video tonight.

First a little backround..... I raced in c class and there were so many people that they had to run qualifyers. I got 3rd and moved to the main. but during the race there was a yellow flag and i gusse they thought i passed so they moved me back to 4th. So when it came to the main i pulled the holshot and lead every lap but the last one. there was a crash and a yellow falg so from the past experance i slowed down and didn't double. but of course 2 people pass me during it and no one saw but my camera but track officals wouldn't look at it but all of you will see. Also they called up the two people that passed me and asked them if they did and of course they said no to get there trophys. then my sis showed them the film and they said that flager doesn't count so you tell me what you guys think when you see it.

[czrider263]

Heres the vid sry the quilty isn't perfect.


<a href="http://media.putfile.com/race1-66" target="_blank">Click here to watch "race1-66"</a>

[eastside 400]

i cant see anything from that video, i was watching tho and u def. passed under caution first moto, u and 076 or whatever jumped passed the kid who slowed down on the first double for the yellow, second moto i couldnt really see it but it looked like the caution was just right before the corner, once u pass the downed person its fair game, i got 2 good jumps yesterday and riding the rest was easy, cant wait to move to A now, i love sleepy's track, the jumps are tight and the triple launches u high and everything about the track is easy

[czrider263]

NOOOOOOO the crash happend on the 6 pack. the guy on the corner warned us to take those slow dude.

[TMSmx47]

LOL!!!! I was the crash..hahahahahah.. I was going for 4th cuz my bad start, passin guys on the outside of the 6pack, got bucked over the bars..lol.. anyway from what I saw, 076 and 111 passed Alex.. flaggers weren't payin attention cuz they ran over to me

[elementryder]

yeh i seen you there you did a great job in the c class i went out in the c class practice and passed you but i was givin my little 3 hunny all it had when you were cruzin the gay guy matt the track manager or sometin told me i had to start backwards before they said any thing about starting backwards if you ran in a different practice but i didnt start backwards and got a 4th overall im allways the fasts kid with a stock engine later man

#01

[chad502ex]

OMG!!! czrider263 that video is wild!

hey chad i wanted to ask you when you did this build did you have to do anything to the seats in the head? or did you just drop the new valves in, as in recut the seats or anything . thanks




-lumi

[czrider263]

You would have to ask chad but i think that he used the old vavles to clean up the seats and poped the new vavles in then but im not sure?

Mike were you up at Rausch Sunday? If you were riding the bike/quad track you must have seen me......

[mike nash]

I hit the track a couple times. Spent all day in the woods getting wet and muddy. Me and my friend were following the markers from the last PA harescrambles race. I wish they opened up earlier on w/e I would have liked to have spent a few more hours in the woods. Next time I'll look for ya,maybe we'll do a DRG drag race:D

[chad502ex]

[E.POWERSPORTS]

So CZ what did you end up for jetting with your Dasa?

[czrider263]

Haven't gotton it tuned in perfect yet prob this weekend or next. so chad can smile again.

[chad502ex]

Well, I had czrider263 come down today in preparation for next weekends race.. czrider263 and DAD drove down from PA to MD to teach them how to degree in the 208 so they can from this point on adjust/shim valves....

Anyway I was able to snap a few pictures from todays visit;then, I took it for a scream ride, and wow this thing is lightning fast.... banged through the gears and next thing i noticed was i was in 5th banging off the rev limit... WOW, that was kewl!

[chad502ex]

and i was extremely grateful for the custom T-shirt... The first of the DRG currently available... the T has all czrider263's sponcors on it....

very nice- thank you.


front side

[chad502ex]

back side of T.

[chad502ex]

one more

:D

[czrider263]

Your welcome chad thanks alot for the leason on degreeing in the 208. can't wait till next weekend!!

[eganracing]

chad,
did u ever re-jet his bike to make it run like it should?

no I rode it today and the engine main seemsed on, just a little 'flat' on low-to-mid. I told him to lean the needle one clip or two and he'll be on until we dyno again...

[cjpoole1]

I have a question for Chad, What do you use to clean gasket material off mating surfaces and what do you use to clean the carbon off of the combustion chamber on the head? Also what do you use when cleaning oil and grime off of engine components(like case halves)? Thanks

[czrider263]

I know he glass beads the heads to clean them.

[chad502ex]

gasket material i use a die-grinder gasket scrub pad. made by 3m works awesome without removing metal from the surface...

carbon deposits, czrider263's is correct, i use glass beading..

oil and grime i use acetone or brake cleaner and elbow grease.

For an everyday joe that doesn't have a sandblaster, can you use the gasket scrub pad to remove the carbon?

[chad502ex]

you can if your not worried about the scrub pad fibers getting eveywhere you don'y want it.... use brake cleaner or acetone and it rubs off on rag...

[gui96]

You never try Honda carburator cleaner ,, this stuf is very good for remove carbon deposit,, its made for this

[czrider263]

A little off topic but this was a small video i shot at my house and a little bit of racing action enjoy.


http://s21.photobucket.com/albums/b292/czrider263/?action=view&current=atvvid.flv

[JoE4554]

dats sweet....nice ltr450....i wish i can make a track in my back yard....but my dad would kick my butt.....im not even allowed to go around my house slow

[chad502ex]

WOW, quit impressive again czrider263 with the video clip.... very kewl.

be sure to video this weekends race on your DRG. :D

[44oEX]

I was reading this post, and noticed that you said that with the 208 he should change his valves springs every 10 hours.

I would like to build up a motor using the 208, I race mx, but I also trail ride alot, and I could probably put 10 hours on a motor in a weekend, so thats no good :huh , are there any better springs that would be avalaible that would last alot longer?

are you using the webcam springs? if not would those be better or worst?

thanks

[czrider263]

Yeah the 208 is suposed to be a killer on vavles! i put a good 4-5 hours on the set and will be tearing it down soon and will be able to test them for wear. As for power the 208 is just flat out nuts. you can run harder spring but that brings timing problems so i just keep a close watch for run time and cross my fingers.

[chad502ex]

How about an 06 DASA vs 06 RE pipe test on your build czrider263?

I'm sure the members here at ATVRIDERS whom have an 06/07 would love to see your machine cranked up past 9400 rpm, and tested against two top pipes... which one will be best?


RE is willing to ship a pipe down to test against the DASA, back-to-back pulls after A/Fr sampling...

you need to give me a call to arrange..

[xsr_racing28c]

DOOOOO IT czrider!!!!!! I want to see the differences!!!~jay

[ghott]

I would definitely like to see that.

I've seen many Rossier vs. DASA graphs on the 04/05 machines, but I don't thin I've seen one on the 06/07's.

good gracious fella- lots of ?'s... hehe

aftermarket ignitions are good for proper spark timing and feeling about up to 1hp more..

circuilar clamp? 3 letter? tack? huh?

i use Rotella T 5W40 Synthetic in engine side after breakin and Rotella T 15W40 in tranny side...

[TMSmx47]

Over-Land 450r... Is your bike black with the Elsinore graphics? Im just wondering if it was you earlier this year that hucked it pretty hard over the bars at E-Towns Spring race at the finishline jump?

No the opposite

the 943 has less lift lol

I call the 943 the 208 'mini-me'. the 943 is almost the same cam with normal base circle and smaller valve lift on the intake.

0.356 intake lift on 943
0.408 intake valve lift on 208


same lobe phasing

same duration

same overlap

same exhaust dur/lift.


essentially, a less agressive 208 that is considered 'drop-in' cause the 943 will not wear springs out on 0.356" lift...

Try not to get confused though about a smaller cam, it is possible to make more power on a smaller came if your port is tuned to flow more at 0.356" than 0.408". In other words, sometimes a cam can be too big and will cause power loss when the valve is full out the velocity falls significantly and the intake charge falls out ouf suspension....

[Over-land 450r]

ohh ok.

sounds like a deceant set-up. let me kno wat it pulls on the dyno. < if u get a chance.
THanks

[stocktires]

Chad, how much are the 943's in price? Is it a regrind or a whole new cam?

[chad502ex]

OK, here are the results for the 943 against the 208..


YES!. Believe it... This was on an 06 mind you...

[chad502ex]

and tq...

[stocktires]

Very Nice!
But why the drop in HP after the build? I know there's a good explanation, just wondering.

huh? the test yesterday was more than 2hp throughout the range with the 943...


maybe, your referring to the 54.xhp this build had.... that was with the FCI intake... these testing was with the stock airbox.

[Over-land 450r]

yeah for a drop in cam thats really good. hell id sacrafic the 2 hp for all the money the 208 requires. lol

OH WAIT A SECOND!!!

please dont get confused,...

the 'drop-in' cam (943) made more power that the 208 cam..

sure and it costs less too!!! :D

[44oEX]

ok, could you please explain how this can be?

Is it just the way the porting has been done?

Or are you saying we should get a 493 instead of a 208?

it just doens't make any sence that the bigger ( supposetly better ) cam made less power, and the 493 would be more reliable anyway.:huh

[xsr_racing28c]

Chad said in a previous post on the dyno testing thread that different cams react with different types of porting.

He said that the 208 was actually too much cam for this motor and was robbing some power.

I'll let him explain more......

~Jay

[44oEX]

how tho? I mean he did port this motor to work with this cam.

Chad can you please explain

thanks
