has anyone tried a product called Powernow, by a company called scaryfast, it goes into the intake and claims to help throttle response.

Yeah,I have one.it's ok.It made for a little better throttle response

Read that it works best of the vacuum slide style carbs used on the 660 Raptor and z-400?

dont waist your money, you will lose power.
the dyno runs I saw only lost 1-2 hp. (loses power up top by restricting flow)dont it seem funny that the seller dont have any proof it works and dont really explain anything about it ?
I see you can now spend 200 and get one for the other side.

if you want to try one out do a post in the wanted section, I bet you can lose the power for alot less than the 100 the new one would cost. (last post I read about this someone replied that they had one they where willing to give away because it worked so well)

yup i gave mine away cuz my quad actually ran worse and started missing the instant that i put it in. If you don't have a cam buy one of those instead of pissing your money away like I did

I installed mine a coulpe of years ago.I really didn't feel that much of a difference.Maybe a little to the low end.It's really not worth the $$$

i installed one on a modded 660 grizzly and it ran pretty bad.

I've never read any reports good enough to make me think I needed one. They are supposed to help it up to half throttle. I want to know what happens when the slide is just a hair above the blade.
