What rwhp are you other twin turbo guys makeing? What should my car make at 15psi, power fc, full exhaust, intake,255lph fuelpump,fm intercooler, and power pulleys. Will I need a diffrent fuel rail and injectors at 15 psi. Any help would be great. I had a friend with this same setup he made 365rwhp. IS that about right?

 

That would be about right. Give or take 30hp.

 

ported?

and yes u need more fuel to run 15psi.
