Is there any calculasion between the 2. So say if u had a 8.5 c/r when you built it and ran a comp test you should know wat the compression should be. Or vice-versa?
13.95 1/4 mile on a 2.95 fd. Carnt be that hard to beat! |

I suppose in theory there would be a relationship between the two. You could work it out with a bit of maths if you assumed a perfect seal. |

but compression is also efected by cam overlap timing etc My small bore turbo project http://www.turbominis.co.uk/forums/index.php?p=vt&tid=473901 |

it will only relate to the dynamic compression at what revs the starter turns the engine over at, not the static c/r one day boost will be mine!

you need to work out the dynamic compression ratio to get an idea of this,
