I just bought some new twin turbos. They are pettit upgraded. I got the impression that they're not that special but I just needed some new turbos for now. I was just wondering in comparison to the 87000 mile old turbos in my car runnig at 10 psi would the ported out turbos I just bought be a big difference running at 15 psi. What kind of horse power do you think I could make at 15 psi with these mods: Apex Power FC, SR High flow fuel pump, Trust Intercooler, Trust cat back exhaust, Racing Beat Downpipe, custom midpipe, and Fluidyne Radiator.

its going to come down to one thing....tuning.

you will be beating corvettes with that setup.

probably around 350rwhp...give or take....if the tuning is great and you have enough fuel (i dont see injectors on your list) then you might make more as well. what about your intake? gotta breath in to breath out....

15psi and 10psi is a huge difference. the pettits arent any faster than the stock twins...you can push 15psi thru both sets...though Id personally keep it down below 14. heat is not good..and you will be producing a lot of heat at that boost level.

if it was me...with those twins...id upgrade my radiator, another oil cooler, the intake, injectors, and fans....keep it as cool as possible in there.
