40hp? If this is real I doubt that. That's only a few ponies less than the 450. And you know this quad is going to cost at least $6500 new, which means there won't be a large market for it.
Ass dyno FTW (sarcasm). I know on Quadracers Vforce 2 and 3 produce more power than the Rad valve. Same goes for Banshees. I'm selling the Rad valve from my LT. The thing is too restrictive with it's tiny 39mm ID intake.
