show me a quad with a stock engine that has over 100 horsepower!....if theres hundreds of them then you should be able to post one right up, 2 stroke or 4 stroke!....the ones you are talking about have motor swaps. They put in snowmobile or Street bike motors to get that many ponies. I still dont believe you and neither does anyone else on this site. So can you please just drop this issue. I dont care if his ATV has 1000 horsepower, youve done ruined it....this subject should be closed.Originally posted by rider@Sep 7 2004, 02:03 PM

Ok, I just got off the phone with Jeff at sparks racing and the following are the numbers he gave me.
416 maxxed out on alcohol 40 to 42 hp
440 maxxed out on alcohol 42 to 46 hp
465 maxxed out on alcohol 49 to 53 hp
They once made a 505 but it was busting the cases and everything even after welding and modifing the cases!
I will leave the thread open for a little while to see how it goes.
Bryn, look man its not a big deal, just like mixxer said the dyno could have been set up wrong giving it a false reading. If Curtis Sparks, the greatest 4 stroke engine builder in the world 4 years running tells me that a alcohol breathing built to the hills 440ex built under his care is putting out 42 to 46 hp, I would believe him any day over someone saying 72 hp, sorry. Mabey your friend added the torque and horsepower together to get the 72, just a though. <_<Originally posted by bryn 271@Sep 8 2004, 06:19 PM
