8.5:1 is the way to go. You'll need to run ~2psi more to make up for the power loss from the pistons, but it's all good. Also, a t3 is too small to make 300hp. It could, but you'll be compressing the air past most T3 trim's efficiency. Possibly look towards a t3/4 for the 15psi you want to run. A t3 for 10psi would be a very good choice, tho. We're (Boosted and I) are just trying to keep you from buying parts, running to their limit, and then buying the same parts again, later. Buy the pistons once, buy the turbo once, and everything else is cheap enough to upgrade over time (injectors, ecu, ect.)
