sounds good to me

in the second half of your question,, are you asking about how to make your engine a low compression engine?
Hi Gareth

No, not really - I guess if I was going to do that, I would replace the pistons with low comp pistons.

I wanted to understand more about what makes a good engine good, particularly when building a very high power 2.0l cosworth engine. I dont mind admitting that when I next get bored, I may look for the next step, but mainly I want to understand what does what! (a big topic indeed i suspect! LOL)

So people say that Low Comp can be made to be very good indeed, I am just curious as to what makes a good one good, and what makes a bad one bad, given that Std comp is not necessarily better than low.
