Need waste gate and bov selection help
Need waste gate and bov selection help Hi,I have 80mm stg3 ball bearing turbo and matching intercooler on the way for my 6.0 iron block LS motor in my G body. Motor has LS9 Cam,H beam rods,JE forged pistons. Compression is right at 10.0;1. I'm running forward facing SS headers with 3" outlet. Will most likely do 2.5" hotside to turbo. A/R on turbo is 1.15. Need some recommendations on waste gate and bov sizes. I plan on running this on street and strip shooting for 900hp at 15psi. Any help would be much appreciated. Thanks

I just built my brother-in-law a S480 T6 kit for his 370. It only has a single PTE 46mm gate mounted into both pipes right before the T6 flange.
The formula for a wastegate is simple:
Big turbo/low boost = bigger wastegate
Big turbo/high Boost = smaller wastegate
Small turbo/high boost = smaller wastegate
Small turbo/low boost = bigger wastegate
