John, do you still recommend the X12 3.5? I would like a little more speed down the straight as the mod TC's are just as fast as me and would like to leave them behind. I have been using an X12 4.5 and can hit full throttle easily in high grip conditions in many parts of the track.
Have you used the Novak Ballistic or any of the GM motors? I was thinking of possibly a delta 6t wind?
Regards
