LiteSpeed: My speed record attempt car...

[Revracer]

wait your planning on using a neu with 4500w right? thats what your "litespeed" thing says... thats over 6hp... the car stock weighs only 2.67lbs... thats a power to weight ratio of like 2.258hp:1lbs... thats unheard of. how will you get power down. its a sick idea but i think your looking at way too much power. the perfect car would have a 1:1 power to weight ratio... what kind of gearing are you going to be using? and can the f103 take any standard 48p gear?

Its all about rolling resistance, momentum, and wind resistance. Tall narrow tires, a long skinny body, and a low Cg (either through weight, or by using aero to achieve it). Look at land speed record vehicles. They are NOT shaped like a lemans car (ie., glorified ferrari/mclaren/etc). Jet bodies are another example. Long, round, and narrow.
If you could get into the programming, you'd want to use as little of your available juice as possible to get up to a certain speed, then crank it up for the high speed burst. Maybe gearing it so that it'll barely get out of its own way to start - as long as you can up to speed and shut down prior to thermalling........heck you might be able to do this without spending much. Maybe spending the money on some custom wheels and a build your chassis based on those land speed vehicles....now I've talked myself into possibly trying one of these!
