nmotion 520 is on the bus

[dunebuggie66]

well my motor is complete by nmotion, and she's on the bus home. she'll arrive friday then i can finish putting her back together. i got the full race 520 kit, oversized stainless valves, porting and head work, 41mm fcr for mx, nmotion pipe, full hinson clutch... cover and all, dynatek ignition. any realistic guess on what hp i should be putting out. chad 502 you should know.

dynatech ignition is not released to public yet and NMotion has only one proto-type in house to test with. Dynatech is planning on releasing this new ignition in a few days,... :D

NMotion 520 kits make incredible hp! I'd guess you'll hit 54hp/38 ft.lbs. of torque.

You'll love it for sure!

keep us posted.

[Orr#34]

It should put out more than that because i have a 400ex that is putting out 54hp. nmotion builds good motors. I seen there 520 at the tt nationals in arkansa. It had amazing power. it was unreal.

[#1speedbump]

well being you have an ignition that hasnt even been released yet I guess you'll hit a huge, whopping 0hp/0tq.

good luck

i call BS! if you have a 54hp 400ex then it would have little if any torque. Torque and HP is a derivitive of one another, so if you build a hp motor, then tq goes towards zero. that's why i say that if you have 54hp on a 400ex motor, then your torque probally sucks. the 400ex motor is a torque design not hp setup. additionally, the 400ex motor has one of the largest stock stroke setups, so if the 400 motor is stroked over stock then tq goes to the roof. imo, you went the wrong way here.

[shaneb]

chad502 you are full of it as usual ...

my 505 makes ~55 and close to 40 on the tq .....

[shaneb]

Your still mad becuase your 502 made the same power as my home built 440 ....

Thats ok at least you are still trying ....

Here is a pic of a 473 making 51.9 ..
this was years ago ...

anyone can download a dyno graph and post as thier own. where is the text printed on the dyno to prove this is yours. I'd almost believe these numbers but not the 55 your claiming. LOL. "almost 40tq" isn't **** either for a stroked 505. my 530 has a smaller stroke and kills your "almost 40tq" and the 530 isn't even setup as a tq'r.

get real boy! and get off my back!

Chad, I was talking with Nate from Nmotion yesterday about their exhaust systems, and I didn't realize that they're not custom building their pipes anymore. I guess according to him they're having them mass produced now. Was the pipe you guys dynoed one of the old custom style pipes, or one of the new mass produced ones?? How's that 530 turbo coming along?? I can't wait to see the dyno results from that beast!!

Joe,

yea 370kingR has a 520 kit dyno'd with the older NMotion pipe. It performed for him but was really really loud. His dyno results and my old runs can be seen on http://www.precision-ms.com

my 530 is making great power 59/43 on stock carb. my website has dyno video and plots to peak at if you want.

hope this helps.

Well son ....

This is not mine it is FDO's

http://www.geocities.com/gtthunder.geo/news_set.html

FDO built my engine as well I was just making a comparison showing the posibility of making 55 hp out of a 400ex

40tq is a good number for a gas ex engine

well, like i said before boy; i would be more apt to believe the 51hp run but not 55. Knowing the whole truth about FDO building your 473 tell more of the story here. FDO builds solid motors. but your assuming (or comparing) your ol' 473 to your new 505 and assuming that it would make more hp? LOL

and i was right, that wasn't your dyno run so why do you think you are making that in your setup?

well im backing chad all the way, he knows his stuff, and obviously has solid proof to back it up, which you dont have, btw nmotion is located in wichita kansas, about 1 and a half hours from me :macho

My Nmotion 520 makes 65hp and 46 ft/lbs of torque......
:)



oh, by the way that's on my homemade dyno. I rode it and said that's fast....lol...

I don't post on here alot but I read alot. Everyone on here thinks that a dyno settles everything. A dyno is just a gauge, it is a tuning tool. Different dyno's give different #'s. A dyno is great to take your own bike to, then change something on your bike, then take your bike back to the same dyno and do another run. Therefore showing what kind of improvement you achieved.

From what I have read Chad seems to be very educated on this subject. He seems to have easy access to a dyno and has spent a small fortune on dyno runs. I believe this post started with someone asking chad's opinion.

Nmotion says that there 520 kit (complete) will make between 55-58hp and 36-39ft/lbs. So I would say chad's guess will be real close.

As far as the 473ex with 51hp, that is much different than 55hp. The FDO graph says that is the highest hp ex they've ever seen.

Anyhow I had my 450 on a dyno(11.5-1,hot cam stage II, some port work, hmf pipe.) 39.95hp@8000,29.64ft/lbs@6000
on maxxis rzrs with 10psi.

My 520 will be together this weekend but I don't have my other set of Walsh a arms yet. When I get them I am taking the 520 back to the dyno to see how it does. I am guessing 48-49hp and 35ft/lbs of torque on the same dyno. Different dyno's would probably give higher numbers, but I am looking at the difference.

ya that dyno sounds very low, you not far from me, do you race at all?

[ml450r]

I race mx. I raced at Thunderhill in Mayetta one time. I mainly race in MO. I run the Caatv mx series. I raced at St. louis pro quad series. I will be at Hamilton this weekend for the first round of the CAATV series.

said perfectly. i can't wait till you run your 520. let us know what you hit!;)

Hey Chad if you read between the lines i think he wants to race you. Or have a dyno challange. oh thats right he will halfto get some one elses bike.:D

Good luck with the 520 and keep us posted on how well it performes.

[Bary McCockalot]

Here's the thing that most of you guys don't realize. With a dyno you can make that thing read any kind of numbers that you want. I know a guy with a dyno and we dyno'd my cr80 motor. it came out at 36hp. Then he told me to come over towards him and said watch this. he messed with a couple of the settings. Then we did another run, and magically, my motor made 45 hp. That's the problem with a dyno, unless everyone is using the same dyno with the same settings your hp number doesn't mean crap compared to someone elses.

Get some flat track tires on that thing next time you do your dyno pulls. Unless you just want to compare then versus now with the same tires.

I am just doing then versus now. The dyno has grooved rollers so you can run knobby tires. I am pretty sure flat track tires would have helped though, I just didn't have any.

Let me settle this argument really quick for you guys. My stock (HMF pipe) 450 can take all of you 520's out there. You wanna know why?.....

Because, you're only going to get a week or two of riding before the engine will need rebuilt. There can't be any reliability to those motors at all.

[dunebuggie66]

about 30 hours on rings, and 60 hours on the piston. i think that's pretty reliable. obviously you have no use for a big bore motor if your';s is still stock. i race opoen class mx where a big bore motor is necessary, so if i have to rebuild it 3 times a year then i will.

let me bow to you, all great one

whoopty doo, you big open class mx rider.
you're still rebuilding it constantly. so that's not reliable.

guys, you're missing the point. Reliable means "not having to work on it".

my point is.......it takes money and tear down after tear down to have and maintain a high hp motor. Such is the case with any engine.

A reliable motor is one that does not need tore down to be maintained.

Chad, i'm not trying to bash what you're doing with your engines. High hp is a wonderful thing!!! I just want people (mainly those who have no engine experience) to know that, building a screaming motor is not all fun and games. There will be blood, sweat, tears, and heartache. lol. And, a torqued up, high hp motor is definately going to require much more wrench turning. That's all i was trying to convey. No one can argue that.

agreed- that's kewl!

it's almost like a meta-stable condition. picture placing a marble on a smoothed rolled mountain-top, once its balanced on the peak its "dialed in", once it begins to roll off on either side of the mountain it hard to maintain "peak power". Insuring the engine stays on top of the mountain is tough and takes an understanding. But really, once built and "dialed in" the only maintenace required is yearly ring changes/valves adjustment/typical oil changes and understanding how octane can keep the engine on top of the mountain (so to speak).
