OK Question for the Turbo Guys, step inside

I am wondering if anyone knows where I can find how much HP a pair of GT3076R internally wastegated turbos would support on a 370cid motor at 10 psi? What about 6, 8, or 12 psi? Anyone have experience in these type applications? Would the compressor map detail where the turbos would choke? Is there other info that I need to provide?

Thanks in advance,
Aaron

Do you have a compressor map for the turbo? If so could you post it or give a link or something.

Amazingly, the compressor map is in the link as provided by SloRvette (thanks for the link). Based on the calculations and the digging I have completed, the GT3076Rs will support ~900HP. I am currently looking for something that will have a bit more room to grow.

Thanks for the great link.

I'm guessing you're looking for an internally wastegated exhaust housing. Hmmm, 370 cu in ? You thinking about modding the C6 ?

I agree with BTF.. the GT35R's are a good way to go.. also you can look into the SC61mm units.. these will support around 1200rwhp.. they are externally gated though and will ned different packaging requirments.. I am likely going to use these on my 368 ZR1 TT build.. but before I commit ot hem I am going to rule out the absolute possibility of fitting a T4 based set as they have a much better flow capacity on the hot side then T3.
