Title: Help with compression calculations Post by: Dave_EH on July 13, 2009, 08:39:22 PM Hi
Wondering if anyone with engine building experience can help me out or direct me a formula that will assist me. I have a 9 port head which has been CC'd at 47.5 I currently run a 179 (192) without any trouble, however am looking at building a new motor. I need to see if its possible to run this on a 202 block without compression being too high. Can anyone help me with piston choice - will the dished ACL pistons availble drop the compression enough? I don't want to run more than around 10:1 - I will be running 98 RON fuel. Please - just responses if you have experience in this. Regards Dave |
