How much power with the above mods 14psi, 16psi??
Thanks

 

14 psi = 320ish
16 psi = 340ish

all depends on how well the PFC is tuned..you could get more...but I think my numbers are realistic

 

please do not run 16 PSI without race gas, and do not run it at that boost level, regardless of what type of gas, for extended peroids of time.

those numbers that Johnny posted are what you should expect, and be glad to have with those mods.

 

just another blown FD Oh well, it's inevitable that lot's of these guys will just turn up the boost to get that extra 20-30 hp and not be tuned for it. It's extremely hard to have tuning for 16 psi on pump gas let alone more than that on the stock twins. 15 is the limit to be safe and should be kept around 12-14. But at 14 psi with those mods 340 rwhp isn't unreasonable. Atleast you have the fuel mods to handle it.

 

All I know is that the BOV is what is giving all that HP. Go baby, GO!!!

 

I think that I'll probably be okay, the most that I try and run is 15 but I run really rich, like 02 sensor readings above 1 volt. It's a Ray Locheed map. I try to just run 10psi normally but after 5500rpm boost creep takes over. I think that I need to figure out how to get rid of the boost creep without losing too much power, any ideas? Maybe a restrictor plate in the exhaust?? I'm going to the dyno soon to find out, probably add some race gas or booster.

Thanks for the replies.

 

sounds like time to port the wastegate...

but you can try pills in the turbolines

 

What do you mean by pills in the turbo lines?
I'm running non sequential so I'm pretty sure that the only line that I have that does anything now is the wastegate line and that runs to the profec b.

Thanks

 

ok then...didn't think about your mod list...when you mentioned boost creep

port that wastegate

 

porting the wastegate requires pulling the turbos right??

 

Yep!

 

Well I went to the dyno and at 10psi she pulled 306rwhp at around 10psi and at around 13.5/14psi she pulled 326 both at 7400 rpm (didnt rev farther, scared). The wide band read 8:1 for most boost and around 8.5:1 7000 on. Way rich, how much power do you think is in there raising the air fuel ratio to 10:1??
This is a Ray Locheed map so any of you with one are probably running rich too.
Time to get a datalogit and go back to the dyno.
Thanks
