Carpenter Racing (seriously considering the 240 hp upgrade package)

350/400 is not that hard & has been done.
With Bob Carpenters vast experience in tuning, if he wanted to do it he would not muck about,
I think the numbers would be higher.
HAVE already made over 500 HP with the little 1500CC destroked Rocket engine mildly tuned so no doubt the 2300 CC ROCKET will make impressive HP like youve never seen before
 
I agree. id kill myself with that much power.
