Just like it says, i was just curious. I have run about 13-14 before and thought it was kinda scary.

thanks

I've heard anywhere from 12-15 PSI is their limit. Any more than that and you're cooking the turbo (it's also /way/ past its efficiency level)

About 13-14 psi is the limit. 12 is still definitely still safe with it. I have heard of guys going up to 16 psi, but as $150FC said, that is way past it's efficiency range and just cooking the turbo.
Keep it under 14psi.
