Okay, everyone talks about making more power with more and more boost. After a while, this becomes unfeasible, or very expensive. Why not raise the compression ratio a little with different pistons or something? Yes, I know that having too high a compression ration and adding boost is bad, but, I'm not talking about 10:1 here, I'm thinking something milder like 8.5:1 or something. Then, the stock turbo with 12 psi would be pretty strong! So, what are the reasons against doing this? As long as you have enough fuel, and enough spark, it shouldn't be a big problem, right?
