I have a 5.3 ish lol with a blow through setup. I use to have a 60mm turbo 13psi setup I ran for a yr. no issues made pretty good power. I recently changed to a 76mm turbo. same 13psi. but since the turbo swap I got a issue of blowing power valves. I think boost pressure is doing it. I've been running normal power valves. is there a boost reference power valve made for higher boost pressure?
Talked to a guy at the track who is suppose to give me information on how to build a custom power valve for boost. but the track trip went pretty well. ended with a [email protected] pass. spinning a 1.50 60ft.
