Im doin a build an just wondering the power i can make with a gt4088r with a .95 back, with all supporting mods and a haltech sport1000

 

550?

 

i am build my car with this turbo also(it came on a nearly finished project i bought back in the fall). My setup is a street ported s4 motor and an e6x. Anybody have an idea of how much boost it would take to see 500hp from this turbo? (running meth also)

 

20-24psi

 

We have done low 500's at around 21 lbs of boost on that turbo. Also the 4088 which is the non ballbearing is a good turbo.

 

S4 irons don't like handling that much power. I'd either upgrade to a S5 rear iron or get the motor doweled before you attempt to make that kind of power.

 

I know that I haven't dyno the car with the gt4088r setup , but i did 12.4 on the quarter mile on 11psi.
