What's the top speed on it already? I have a 79' 250 TX and it does 67.5mph tops!! that's fast enough it'll keep up with my dads tx 500 and moms tx 335 easily as well as run with the new formula 380's without a problem. i would just clutch the sled, and hook it up with NOS

The fan motors are off ducted RC jets. Forced air induction. Think outside the box. It's really pretty easy to do. Just make sure to pull the intake in from outside the hood as the cooler air is more dense than the under hood air on the free air.

and i supose your going to tell us that you have to start up a bunch of RC engines mounted to your airbox. those fan units need to be spun at 30,000 rpm to make any pressure. super chargers do not work well on two stroke engines. A friend of mine drag races a honda trx drag quad. he built a super changed trx engine he said that the super charger added no power until they restricted the exhaust outlet. in fact they used a water shut off valve and thats the only way the super charger will build any pressure. because there is little back pressure on the exhaust if you pressurize the intake it does nothing. the slight increase in cold air available might add a few meager hp but thats it.

true TXSRULES, i read an article once (and only once) they ask a driver (after winning a speed run), "is it true that it takes HP to pull weight and if so, if you lost 10 pounds, would that make you go faster"(he was a bigger guy)? he said "YES, but building 10 more horse power would be easier"!
