I JUST bought a Greddy ProfecB and my car is COMPLETELY stock except for a Greddy BOV and a TRD drop in filter.

So can I run the BPU 18psi before I have the DP and exhaust? If not,how much CAN I run?

If you dont have a BCC or FCD then you won't be able to get anything past 1.0 bar (14.7psi). But with that and stock exhaust and stock airfilter without a dp, I was able to get 17-18psi.

and that is with a greddy profec b

So a Greddy Profec B and a BCC nets 18psi? How much power did you lay down? 1/4 mile times?

Actually I didnt dyno or run the car with just those parts. I just know from when I had taken everything off of the car except the ebc and fcd during my smog test, and according to my boost gauge I was still able to hit 17 psi. Now with my dp back in and intake, exhaust and so forth I can hit 17 psi no problem, in fact i can go all the way to 22 no problem (not like I am doing that with crappy 91 octane in Cali). I dynoed at 370 RWHP at just under 17 psi with everything in, and ran a crappy 13.4 @ 114 with just under 17 psi due to poor 60 foot times. I expect with a little practice that I can get 12 second passes with just BPU+.

How bad is it to boost 17-18psi with stock cats and exhaust on the turbos and the engine? Will there be way to much backpressure?

 

[Guest]

There shouldn't be any problem other than the fact that it is harder to spool up the turbos.

I say, just turn low to 1.0bar and if their a high to 1.8bar, and happy booostin.
