Obviously this can depend quite a bit, but just wondering what you guys have seen from your experiences. Only running about 525 or so rwhp, I ordered a twin turbo kit and plan to run that at a conservative 600 or so. I have a PPE Stage V kit installed in my trans. How many passes can I expect at that power level before the trans or converter will need a refresh? I have no idea what to expect, could be 50 or could be 100?
