OP here if me you really need to check are get the pistons & rods balanced together to make sure they are spot on. I did the same set up as you are showing in the box. But I went with the stock comp 11:5:1 and they were off by what the engine builder told me that he wouldn't do these at what was the weight diffs. Robert

I have 16 Stingray with a built motor (10.5:1) on a Procharger P1-SC (3.55 upper/8.125 lower) at 12psi on the dyno (13 on the street) making 790rwhp. I'm on 93oct with meth if that gives you an idea.

I am thinking around 12-14 psi. No meth. 93 pump gas. My guess is 750rwhp on a safe tune. That's a beast you have. Enjoy her, keep nannies ON!!!!

Just watch your fueling. I'm at the limits of my fuel system (38% fuel lobe is my only fuel mod). At the top of 4th my low side fuel pressure is a little low. My AFRs are spot on and high side fuel is fine but low side not so much. It's fine for the HP I have but I can't go any higher without a low side system.
