What Boost Can I Run With My Mods

[r33madd]

Hi all with the below mods what boost will i be safe running as a hi boost setting.

I am curently running low-boost = 10psi and hi-boost = 12psi

Can i up hi-boost to 14-15psi with the factory turbo with the below mods or should i leave it at 12psi

Factory turbo

HKS 3" exhaust From turbo + HKS Hiper muffler

HKS super flow pod filter + Cold air intake

HKS EVC 5 boost controller

Apexi SAFC-II + Dyno tune

Greddy Type R blow off valve

Autobarn88 600x300x76 intercooler

Sard Fuel pressure reg @ 40psi

Walbro 500hp Fuel pump

NGK Iridum Spark plugs at .8mm gap

12psi is about the limits of the compressor

running more boost does nothing more than dial in more heat, risk the ceramic exhaust wheel and increase the change of detonation

well i have had mine as high at 15.9 for short burst in the scramble boost for 5 seconds, but i wouldn't recomend it. I have had my tunner reach 14psi no probs on a safe tune, but this is only recomended for short power runs. The R33 turbo has a max efficiency of 12.x psi, can't remember exact figures, after that the increase in air flow is not as large as say goign form 7 to 9 psi.

It is possible. I have run my car wiht higher boost settign for 2 months now, no issues, turbo looks and spins as if it were brand new.

Sounds like a highflow and retune might be the better option?
