what is the max boost a gt25 is capable of?

[joker2]

i unhooked the hose to the waste gate and the most boost i can get at wot is 15 psi. i've checked for intake leaks and exhaust leaks but have none. is that all it is capable of or is there anywhere else to look.
thank you.

I thought I read somewhere that it was between 15-17.

I could get 17lbs out of my gt25 but after about 15 you don,t get anymore hp. it looses efficiancy.

seen 19 on mine this year.have you tryed the wastgate rod sometimes there not all the way out. it depends on houseing you have but the gt25 alpine uses is best up to 16 pounds after that its only good for short runs it builds to much heat & wont make you anymore power.

thanks guy
i was under the impression that the gt25 was capable of boosting up to 18 psi then getting inefficient. i guess that is all she's got.
