As a "purist" myself I know exactly what you mean ZShift. I race Vipers - talk about no driver assist features. What is this ABS you speak of?
If your tranny holds up it will no doubt sell. But I imagine it will classed. It's hardly fair to expect a clutch car to negotiate Sebring's 3.7 mile 17 turns lap after lap just as fast as your tranny.
The draggers are a different story. They're just trying to cover 1320 ft as fast as they can. Your market at the dragstrip might be better than expected.
