Well sir, I'm only making a street car but I reckon on around 400bhp. Give me a chance to get used to the car before I point it anywhere near a track.
I'm sure I can muster enough out of my tired, old, agricultural 440 to get those rears spinning. Well, one of them at least until I fit a proper rear axle.
So I had better get my tire sizes right if I'm going to be ordering a lot of them(!)
