Not dynoe info.. but a wild edjumicated guess would put it at about 27 HP w/ pipe/filter.

The ATC350X is rated at 27@the crank by Honda I believe so a filtered/jetted/piped one would probably put that down at the tires. I had one before my Raptor that was done up with the 3 mods and it ran pretty good against other quads and trikes until the Z400, Raptor and Predator cam out.

^^^^ That sounds about right...


Looks like you got a good running Raptor there. What cam is in it? Where did you get it dyno'd? I have a friend looking to get one soon....

I have the stock cam still so Ive got a couple of hp on the table yet for me. I dynoed it locally here in Tuscaloosa Co in Alabama on a car Dynojet. I have seen quite a few 400EXs dyno 30hp or so at the tires so 27 on a 350X and dead on tuning would probably be right with good selection on parts...but thats just me guessing.

Here is a 350x motor that was dropped into a 250x frame. It has a Supertrapp Exhaust, K&N filter. The motor is stock for the most part. 27hp could reached on a 350x, but it is not that stock. It would take motor work to reach 27hp. 400ex is 25-27hp Stock with slicks. You cannot trust the #'s from a car dyno when it comes to ATV #'s. Car dyno drums way to much.

By the way it was explained to me by Dynojet when I called em about it they said it would still be pretty accurate since it takes x amount TQ to spin the rollers up x speed in x amount of time. He said the main issue would be spinning on the roller which I agree with that since Ive been there done that lol.
