the real question is..what kind of engine is in that Go Kart! :-)

There are some karts that will run sub 9's in the 1/4 mile.

Yup, prolly a 500cc motorcycle engine. Those shiftercarts can hit 150 mph real quick. Figure 550cc engine (bored) and a 50 lb cart with a XXlb driver.

But which one will pick up the womenz :-)

I've seen a youtube vid of a car built on lithium ion batteries that could outrun a corvette. It had something to do about the lack of need to shift gears in the little battery car.

I'm not sure I'd like to be in something that fast that is that small and open...I would be scared sh!tless

In a straight line it always boils down to this formula:

HP to Weight Ratio

Of course how the HP is applied to the ground (traction) is a big factor.

Man, I wish they had those at my local mini-golf / slick track. :-) It'd be insane!!
