Umm yeah sled engines in go carts Funny story hehe its a BAD IDEA, way to fast one could say uncontrolable. I put one of my 670's in a gocart once, good in a straight line but didnt corner so well and Im thinkin now lookin back on it better BRAKES woulda kept me outa the sticks too

Holy crap.. That would have been alot of fun, but crazy also...

[glengine]

There is other math that is all involved in figureing the compression ratio out..

Well cmon you must have a rough idea

It is built to run at 14.1:1 ...

Running AV gas doesn't do much morew than PREM fuel does.... I dont carte what people say, i've talked to people that fly planes and know fuel... Do you want to be running something in your sled that is designed to be run at aminimum of 10,000ft, as avgas is..., Av gas is alot dryer tham prem or race fuel... From what you where saying i think you'd only have to add like v3G of vp111 per tank... The 860 kit's that we do which run a 14.1:1 comp ratio... 145psi comp on a new, non-broke-in motor.. We tell people to run 2-3G of vp111 per tank.. They dont have a prolem... If you bring in a jerry can we'll pump some for you or you can buy a barrel.. The barrell's of av gas are only like 30-40 bucks cheaper a drum than vp 111, so as far as i'm concerned whats the point of even bothering with av.....

I might try some race gas next time i'm in the mountain's. The av gas I picked up lasy week was 1.44/liter so the race fuel is a lot more.
