How to CC your engine properly.

I have an ITR engine with JE low compression pistons and I would like to find out what is my compression ratio. How can I measure that?

If you know the specs for everything in the engine (like the specifics of the pistons), you can use the compression calculator at http://www.c-speedracing.com

If you want to get an exact number, calculate swept volume (volume of a cylinder) and use a buret with Marvel Mystery Oil to take the volume of the chamber at TDC.

Your compression ratio is (volume of chamber at TDC + swept volume / volume of chamber at TDC)

Re: How to CC your engine properly. (Sonny)

thanks for your suggestions, but:

First one I can't do since it requires the piston / deck distance which I am questioning.

Second suggestion sounds a lot better, but could you please explain in more detail the procedure that I would have to go through. Or better yet maybe someone know a web page that goes step by step through this procedure.

Thanks,
