As the thread implies, what do I need for inside a 727 for survival and reliability at that level? Any experiences?

Monty, a nitrous racer that used to post on hear said he started breaking output shafts at about that level. It is possible that the torque he had was higher than that due to the nitrous.

Hi, thanks for the replies I have some good stuff in it at the moment. Billet drum, 5 pinion steel planetary (front), bolt in sprag (standard # of elements though) LBA MVB etc etc. I was going to add H/D or billet I/p and O/p shafts and hope for the best. I don't mind the maintenance, how often were they pulling it apart Mark? That having been said, I just rebuilt mine after 4 seasons and it didn't really need it. The current motor is not into 4 figures though. Do I need to do more? I'd rather not go to a th400 TIA. Tig
