Well we did quite a bit of testing with the beastly Prowler 1000 and are pleased with the end results. Cams, exhaust, clutching and small intake mods can make almost 10rwhp. Those are some great gains, and i must say.. this thing is just wicked fast! Almost scary.. acceleration is absolutely insane! We even tested this against a stocker and at 50mph ours already had 3 lengths on it... while spinning the tires like crazy! Its one of the coolest sounding off road machines I've ever heard!
