While looking at YouTube videos, I found this video. Its about getting more power out of an formula F1 engine. These engines are relatively small, but by using high precision components, in this case cylinders and pistons, they produce a lot more power. Only because of the better fit of the piston, and the use of better piston rings.
Something to think about !!
What I am thinking is, if we try to get more compression using new pistons (with a dome shape head) and modern rings, that might give more power as well just because we will lose less pressure because of the better fit 🙂
