Use current turbo or go bigger?
Hey guys,
I have a GT3076 .63 turbine A/R and a rather small .50 compressor A/R. I will be running it with a full-race ramhorn manifold. The previous owner claimed 503whp at 13.5psi. That sounds about 100whp higher than normal. I am wanting to get to 500whp with no more than 15psi.
I am struggling to get any worth while info as its such a small compressor size. Any information or educated guess work will be extremely appreciated.
My other option will be to build this turbo out to support what i would like. Thanks guys.

Really don't know how to guide you with this one. But I made 454 whp and 327wtq on 14.5psi with a small restrictive filter and with a larger more flowing filter I made 472whp all on a mustang DYNO. I have a Borg Warner s366 with a .91 A/R and a divided housing THE TURBO IS HUGE!!!! similar in size to a GT40. The car is all top end.

Thanks for your reply!

Sorry man that's just not realistic enough to believe. Even at max efficiency say 18-19psi you'd be hard pressed to squeeze 500 out of that turbo. On the other hand if you pickup a gtx30r you could hit 500 + but once again it's not gunna happen at 13psi. You want 500 whp what type of gas will you be running pump or e85? Stock or built block? You won't hit 500 on pump without a thicker hg, built block with lower comp pistons or water/meth injection. Please give us more info

Ive seen this turbo hit over 500 on a few setups they were on 100 octane or e85. One friend I had hit 568 on a dynapack with 100 octane at 19psi on a k20 on a full race kit. A couple other friends hit close to 500 with that turbo on stock engines.

AEM series 2
Mac Boost Solenoid
Full Race Ramhorn manifold
900cc Bosch Saturated (same as 1000cc matched ID1000's) from LJ @ Full Blown
Walbro 255lph fuel pump
Synapse BOV
Synapse Wastegate(Open dump)
3 inch turbo back Inline pro exhaust
Godspeed Type WX Intercooler
2.5" intercooler pipes
velocity stack 3"intake
I think that's all the stuff that matters for power!

I wasn't recommending it just throwing it out there as an option I have a built block because I wanted 500 whp on pump without wmi. On stock compression you'll have detonation issues before you reach 500whp without water meth so you are gunna rely on it somewhat to make the power you want. And 3en I should have clarified on pump alone that turbo will be hard pressed to hit 500whp

I'm not sure where to guess though. I need someone with solid numbers.

Goon anything over 14ish psi with 11:1 compression your goin to cut it close with detonation(that's why most tuners stop around 13-14 on stock block, I would be happy with mid 400 numbers and call it a day. Anywho hopefully some people with that turbo can chime in
