I've always thot about building a more serious version with a 250cc or bigger motorcycle engine. In fact, a year or so ago I gave away (to a friend's HS kid) a Datsun B210 with a tiny 4 banger that was rated at 65hp. And yes, before giving it away, I seriously considered a cart conversion - LOL.
My BIL used to race sprint karts, in fact he won the Grand National title one year. Once a year he would take it to Mosport and race it with the enduros. I went one year and had the opportunity to run it around the track a couple of times. My lap times sucked but running down the straitaway I must have got it up to 60 or 70, and you are right- having your a$$ that close to the ground really amplifies the sensation of speed.
I had a ride in a car once going 160, but there was no comparison to that kart ride.
