Depending on the gearing it should do a lot more than that...

Are you talking about the snowmobile?
The guy at Yamaha said the newer models would pull away at 95. I dont know, the fastest ive gone is probably 40 in the backyard(large open space). My dad races traffic on a main road though, pretty amusing. Hes a reserve police officer, so when the cops drive by, they wave.

I've got an old go-kart at my parents' house. It has the #11 Darrel Waltrip Mt. Dew Buick stock car body on it. Fun little sucker.

his go cart goes 85. Its stupid fast. But, you 'bout burn your arm shifting it, as the shifter is right on the engine... And the cart is so little you barely fit.
 
Its fun though. very bumpy, but fun.

Sadly enough, I have a friend (engineering major) who's building a steam engine, and putting it in a go-cart.

Fastest I've been is 115 on a sled, I think I have a video somewhere on my computer of 106 though.

10-15 h.p.? come on dude.  roll with something small like a 500 c.c. twin 2 stroke iron bore polaris motor.  Maybe a scant 80 h.p. or so.
 
your engine budget stinks.

You may see 150 mph or more on a cart if set up right.  Rough guess.  Maybe 180 mph.  There's no resistance on a cart to speak of.  Gear it for 90 and you'll roast the tires off.

Everyone suggesting over 10HP realizes that this is a home-built project right? My guess is that his budget doesn't include a roll cage or even a welded tubular frame.

then it's not worth doing. Lawn mower engines go cheap on ebay.............
 
seriously though.  Judging the scale of this project,  a dirt bike or sled engine is going to require too much fabrication for the drive line.  it would be complicated.
 
I've got a buddy that stuffed a 170 h.p. 2 stroke into a golf cart.  if you get serious let me know and i'll hit him up on the drive line stuff

Get yourself a cheap older snowmobile.  Then you will have a powerful engine, good centrifugal clutch, and drive assembly.

The variable ratio primary and secondary from a sled would be needed but the question would be how to eliminate the gears and gear case.  If you went with sprokets you'd want to design the system so you could change out sprockets easily.  It will involve some serious experimentation.  Or you could try to incorporate the chaincase with gears and chain inside.  Using the gearcase would make things easier in the long run but it could get expensive trying different gears which could lead to different length chains.  You could tip the cart on its side to save oil when changing gears.
 
we're talking pretty complicated fabrication trying to get the power from the chaincase to the drive shaft.  the easiest way would probably try to figure out how to place the chaincase outboard of the rear tire.
 
I've got a 3.75 h.p. vert. shaft engine I was going to work onto a Razor type thingy.  You know basically a skateboard with a steering bar.  My plan was to use a tire on the vert. shaft which would make contact with the inside of one of the rear tires.  If you had an engine mount that allowed for vertical adjustment you could change ratios simply by adjusting the height at which the drive tire makes contact with the rear tire. You would also have to have horizontal adjustability too. It would save spending money/time on sprockets, gears etc.

I think every group of friends at one time has wanted to build a go kart.
