trust me... iv gone through a few trannies, they suck. never ever drop the clutch... even at the track... you are doing nothing but spinning tire.. therefore you are raising your et's.. either way dont abuse the car... with the power you are making, [censored] will break.
one question.. you said that the car was detonating untill you put some 100 octane in it? id go right back to street stuff... you dont know how dangerous detonation is when you have a power adder... if it still does that with 93 octane then your motor wont be holding up together for much longer
