Increasing compression ratio??
Hi,
I've been reading 'how stuff works', (great website BTW thanks), and it surgests one way of increasing hp is to increase the compression ratio.
Obviously I want a reliable engine, but is there a way to do this and is it worth while?
Also, I guess an intercooler can only be used on a car using forced induction?
Thanks for the help,
Paul.

Intercooler for forced induction only.

Ahh, thanks man.
I was under the impression aftermarket heads were bigger so more fuel/air could be burned, not smaller to compress more
Thanks for clearing that up for me,
Paul.

bigger intake runner=more air can get into the engine, and smaller chambers means higher compression which will give you more power.
that is of course, you match the heads with your engine, you dont want huge 230cc intake runners on a 100% stock engine, you are going to have 0 low end torque, and its going to run like crap
edit* but ways to increase compression are to use smaller combustion chamber sizes like said, use domed pistons, mill the block/head, and a thinner intake gasket
