I know it would not be FB,but a stock gsxr Stohr F1000 runs FB so I thought someone here may know the answer. I was entertaining the idea of a Stohr F1000 purchase,but really prefer the Hayabusa/Bking powerplant,as I mostly do HPDEs and TTs,and the Haya motor is a bit more rugged from what I have seen and heard. Stohr also makes a conversion kit to do a Haya motor in the car. Is there a class that the Stohr with a Haya motor could be legally run in and be competitive or should I reconsider and buy a different formula car?I'd like sequential shifting and 200ish hp. I am running an Atom now,but it is not a formula car. Thanks.
