Re: pushing stock turbos to limits
I think they will peak around 20 and quickly drop off. However, do not just turn up the boost.

Re: pushing stock turbos to limits
I seem to remember hearing that they blow nothing but hot air after like 15.

Re: pushing stock turbos to limits
They are out of the efecentcy after aprox 15psi, however your car will keep going faster the more boost your push, which has been proven many times.

Re: pushing stock turbos to limits
usually you want to max out the stock turbos at 14.5 psi. at 15 your stock y pipe will get blown off.

Re: pushing stock turbos to limits
It should hold a lot higher than that, if yours is blowing off at 15 you need to tighten the bitch down.

Re: pushing stock turbos to limits
run them at 14.5 psi until you get upgraded turbos
