CT20 turbo overboost Options

[Island_Racer]

How capable are these turbos at surviving pressure above 18psi. Ive heard "hot air" etc...but i have a water injection system....i can clamp the signal and tune beyond the 18psi fuel cut but what other than hot air should i be concerned about? and do you think the water injection can cover that?

Island Racer, this has already been done.

you sir, are a great help...Jim seems to have done what i was curious was possible....im just curious now how long his turbo lasted....

one other thing....its kinda interesting that "Jim" made 330whp @ 21psi using the ct20 while "cuts the pilot" two charts after made 355whp @ 22psi using a gt30...id have thought it would have made a bit more at that at that amount of boost......i can imagine though his turbo was prolly just yawning compared to the ct that prolly having close to a heart attack....lol

And Batman made 329hp at 19psi.

Tuning the ignition timing map has a lot to do with how much power is made. Cuts The Pilot is running an aftermarket ECU that is not properly tuned.
