Hey guys...im probably going to add nitrous to my car in a few months and i was thinking about my tranny. i believe it is a TH350 (maybe a 700R4) with 150k on it. How much horsepower are these things rated at (300 i think??). would they be able to handle my 400 HP when im on nitrous? If they wont, What could i get that wont make a hole in my wallet?
