Here is my setup.

laskey racing block/head
GT35r
lovefab mine-me
tial WG/BOV
RC 1000cc
AEM EMS
3" from the turbo to the back.
cc stage 3 clutch.

MY car was just tune by MASE and all i made was 427whp @17psi pump gas

what i need to make 500whp pump gas?

 

More boost or a bigger turbo.

 

more boost lol or water/meth.

 

According to mase, i was having boost creep after 17 PSi , he told me most likely it was the manifold design. I made the same power in Co 7000ft of altitude with 91 oct =/

 

only 427whp? haha only... i wish i had that.

 

Id be pissed off with only 427 with what you have...
What kind of dyno were you on?

 

Switch over to an Equal Length manifold?

 

Precision 6262 would help for more power, better manifold, or more boost/meth. I would go with meth myself, then you can really push it on pump.

 

What Compression ratio are you running?

Are you sure everything is 100% in the motor and you don't have any boost leaks, the intercooler is flowing perfectly, the manifold matched up to the head properly....

Why did he stop at 17PSI, where you having issues?

Which GT35R?

If you are running 9:1 or so you should be able to get to 20PSI on pump and 25 or so on meth. I am running 19.5-20.5 in my old ladies STI on pump with a less inefficient turbo and intercooler.

I would not replace the manifold until you do some EMAP and EGT logging.

 

427 at 17psi and maybe higher?.... sounds like u already have alot of boost....
