Most of the fast track times I have seen reported here are running Magnuson. The heartbeat setup can get you trap speeds into the 130's pretty easy.
That being said, I do think the F1A is top dawg but it's not worth it unless you plan n building the motor to utilize it's true potential. The problem I see with the P1 and D1 on the manual cars is they fall out of power on shift. The A8 should be better with a Centri.
