How can I go 50mph on a go-kart?

Go-kart Specs:

6.5hp engine
3600 rpm
16in tire diameter
3/4 shaft

I don't have the engine yet. its on the way. I need a 6.5 hp engine to go at least 50mph with the engine specs of 6.5 hp, 3600rpm, and the tire is 16 in in diameter. Is there a way I can get it this fast? The rear axle is 3/4 in diameter and the same with the shaft. I can find the right combination of clutch, sprocket and chain to go that fast. Ive used a sprocket calculator, but I cant find the right sized sprocket any where! The main combo I was looking for was a 12 tooth clutch and 12 tooth rear axle sprocket. I can find the sprockets but with 2 different chain pitch size of #35 and #40! I need help!!!! If I cant use the chain driven way then I need some specs on how to use a belt on it.
that does not help at all!

Saw a go-cart with a Harley engine on it. It was clocked at 120 mph on the runway of the Fargo, ND airport. Most of the time it was air born though.
I have also seen go carts with McCulloch chainsaw engines on them.
2 engines for racing, one on each rear wheel. Otherwise just one engine. The wind-up up to 8000 rpms.
