top speed has less to do with weight and power than it has to do with coefficient of drag. a drop tank at bonneville could prolly hit 200 with maybe 300 rwhp? as an added complication, traction usually becomes the limiting factor when you have a lot of power in a brick. you're up against an aerodynamic "brick wall". spinning your wheels trying to push the car through the air. the salt doesn't have real good traction, relatively speaking, so minimizing aerodynamic drag is job one. then move on to the other stuff. weight is often times your friend when going for all out speed. weight can improve traction. i would love to take my scamp to the salt and see if it will do 200, but i know that as it sits, though it may have enough power, it's a box on a box, and there is no way that's gonna happen. it would have to be MUCH slipperier.
