If ya really want to wake up your quad and improve the performance add a couple mild mod’s and get it DYNO TUNED… for what it cost I am very pleased - Thanks to the guys @ SANDTRAX for an awesome job.

Different types of mod’s like… (pipe, air filter, header, jetting, cam, lid off, ect) will of course give you different result. The type of mod’s and the quad are going to vary in the results that you get. Just like to share my results and hope other would do the same.

I have attached a vid with before and after results and spec's.

Would like to hear from some others that have added some mod's and then got it dyno tune and their results. PLEASE POST UP SOME NUMBERS AND SPEC'S :)

Thanks - well the closest i found to ya -- heres a link -

http://www.exriders.com/vbb/showthread.php?s=&threadid=362670

i am sure this guy might know some one closer to ya. but if anyone is in or near Oklahoma the place to go is Sandtrax - Awesome tech's.... very reasonable pricing. And they get it right the 1st time - it takes out all the guess work we all do trying to get that perfect tune.

Went out this weekend to test her out....ran with some super mod'ed quads and stay with them, it was in the sand about a 4th gear drag.... did pretty good, will post up a vid this week.

09-22-2008, 07:26 PM

this should be illegal to make my quad look so slow and weak lol my 400ex has power but man 48HP with simple mods dang i wont see that that in my 400ex lifetime. I would be lucky to see 37HP. what did it cost you to dyno and test off hand?

Dunerider32

09-22-2008, 07:47 PM

i got mine done for about $150 that was tuning as well

mak400ex

09-22-2008, 08:16 PM

Hey whatsup FHR,
the 400ex is bulletproof had one and i diff miss it, thay are a great all around quad. my son has one and he stays up with me. must be the rider.... lol

most recent mod's:
Well got a great deal on the cam/kit $150

Cam installed, carb work
and all the dyno tuning time $195

The ride PRICELESS

went from stock 37hp to 48.3hp

not bad for some mild molds

Dyno tuning per hour is around $75 @ SANTRAX
the norm is about an hour to get it tuned in, these guys are fast and great at what they do.

Cool - thats is some great result, you can really tell the diff with every hp added.

The tech's also said that a good rule of thumb is for every 1hp added to ya quad vs stock is about 2 to 3 lengths at the end of the run. (drag race)

09-22-2008, 08:25 PM

I talked to the guy at my local Honda dealer and they do dyno testing and tuning. They charge a lot to tune your carb but I would do it by myself. They guy back in the mechanics department when i taked to him I clearly said how much for the air fuel testing too? he told me $35 for 3 runs and the air fuel testing. So 3 runs I can jeck out my jetting and numbers. If it needs a change I will play with the carb in the parking lot and just buy another 3 runs so it will be $70. They wanted $65 an hour to do the testing and tuning themselves but for that price the pople obviously wouldnt be working at a fast pace they would be in turtle mode. So knowing a dealership they would charge for 2 hours at least.

Your right on with that statement - you will get really close and for the $ it will be worth it,

keep me post on your results

09-22-2008, 08:45 PM

will do. I actually want to do a couple runs at different times. How my quad is now. Then with a 406 10:1 wiseco, possbily HRC cam. Then with that and the 04/05 450r carb. After that i am hoping to be pushing at least 35hp.

mak400ex

09-22-2008, 09:04 PM

Sounds good - you should get pretty close to that HP with all those mod's - it will be one fast 400+ :macho

Nice numbers. I am going to cam and jet mine when it goes for the valve inspection, probably change to a UNI filter as well.

I noticed the same jet kit that cost $18 online is $60 at my dealership, I picked it up thinking it was marked up maybe $10 but I would not be paying shipping and would "get it now".....I am glad I asked to price check because I was buying a lot of other stuff and would not have noticed until I got home.

Cool - you will really see a diff in performace when ya get your cam in - yep gotta watch the dealership on their prices, i got the hrc cam/kit and when i got it dyno tuned the tech had everything i needed on site as they tuned it - they are a family owned shop and they treat ya right - no price gouging here. real happy with the cost and work that was done.

I like the plan. And it's something I'm sure lots of people would be interested in reading about.

Depending on things, I'd try and find a good way to communicate why you're really there. You're there for tuning versus just being curious or whatever. If the shop understands that they might look at you as a different kind of customer. You don't want your tuning sessions to be hampered by any set number of runs (unless that ends up being cheaper than some alternative arrangement, I guess).

3 runs for $35 sounds sounds great if you're just curious and want a number. However I've had dyno tuning sessions where my bike was strapped to the dyno for less than 2 hours and we must have done three dozen pulls. Maybe more. It seemed like a whole bunch (big fans kept temps ok). We did not have the benefit of an a/f meter. But still, if I'm gonna be fitting a different carb I'd much prefer some flexibility in the number of runs pulled.

I could be off base but maybe it's something to think about. First time I ever had a bike of mine dyno'd it was something like $40 for a HP chart and an extra $20 for the torque too. I asked about why and was told something that was mostly nonsense. It was zero extra work for them to get both HP and torque. But they weren't really about tuning. They were more about just getting a number and their prices reflected that. I've been to three different dynos now and the last time was great. I was able to participate to an extent that fell just short of me actually operating the bike on the dyno. I did all the jet swaps and other work while the dyno guy worked on other bikes. Then we'd dyno the changes I just made, he might make suggestions, and so-on.

So if you're lucky and you've got choices, you want to find a dyno like that. And if you've only got one choice, you want to turn it into a dyno like that (if possible).

That sounds about right - i paid $75 a hour for my dyno tuning, plus parts if needed - for the money spent it was worth it, and the info ya get from the techs is priceless, learned a lot in 1 session.

I guess I will make my first post in someone I know and ride withs thread. I have an 07 TRX450 with Evo R exhaust, 158 main jet, clip in middle of needle, Sparks TT drag cam, K&N and precharger, and pulled rev wire and I'm putting out 47.96 hp. I will also agree that the guys at Sandtrax are awesome. First time I went in there they told me I wouldnt get good dyno results with the EVO pipe, after running it they just kind of scratched thier chins and said "Whoops guess Big Gun started making better pipes". The last time I dyno'd it the power never dipped and wasnt up and down, stayed steady through the whole curve with minor tweaking. We'll see what it looks like after I put the 15:1 head in it and a new accelerator pump in. Till then Ill just sit, wait and scheme on how I can beak MAK!

now we got to watch out for the noob.... "CAK" his 450r is pretty quick after we installed the HRC kit and at a buck fiddy he's got the weight advanage:D

i pulled 67hp/43tq out of my 471 trx with +1 valves all around/dasa pipe/stage-3 HC/43mm carb/decked head/13.5 CP piston/and my porting....

the printer was broken when the runs were made, so i'll get the sheets when i go back nextweek

its amazing what you can do when you study these engines and test different things.........but porting is the MOST important thing in the package.

i currently have the head for sale for $300 shipped........you'll NEVER find a head that can pull that kind of power for the price im selling it for.

and i'll give a refund if it does perform to your liking.:macho

First off why would you think anyone in the TRX450 forum gives a rats *** about your HP numbers? Why you may claim to have 53 hp how well does your quad handle, how much does it weigh? You can have all the hp in the world but if you ride a heavy quad or one that handles like a turd then it doesnt matter. I think you also might have made the above post to compensate for something, small penis maybe, or maybe your daddy didnt love you enough. Either way this thread was started just to tell people how to get a few extra hp with MILD mods, not as a pissing contest between what quad is better.

On another note you say Honda ATVs are weak but I can guarantee you'll see more Hondas out at the track or trails then you will Can Am's so you must be basing your opinion of Honda quads on what happens in your little fantasy world, either way your post just pretty much confirmed you place in the douchbag hall of fame.
