Not enough torque. Need I say more? Actually, I shouldn't jump to such a conclusion. You never said what size wheels you were using. But assiming you wanted to go 112 mph, you would need a wheel approximately 2" in diameter on the 19670 rpm drill shaft. Now, at stall the wheel would only be able to exert approximately 7.9 lbs of force on the ground. As motor speed goes up, torque goes down. So, I reckon moving at 112 mph (near 19670 rpm), you will have very little torque, certainly not enough to counter the air resistence.

Aside from that, I am fully willing to help with this project in any way possible if anyone will be working on it in the southern california area. While I've been fading from the hobby in recent years, I do have many years experience with RC cars and have 9 cars , both nitro and electric and have cutsom built frames before. This sounds like a fun challenge and I'm certainly willing to work with anyone who wishes to enter.
