donkeypuncher Posted June 18, 2009 Report Posted June 18, 2009 do you want to run pump gas, 50/50 pump/race mix, or straight race gas? whats your current compression? Quote

I forgot how much my compression is. you need to figure out your compression before you decide what domes to buy. do you atleast know what your timing is set at? and your elevation? generally speaking you should be fine with 21cc domes, but depending on your timing and elevation you may be able to run smaller domes and still be able to run pump fuel.

Thank you I'll go and find out what compression and i'll be in touch with you again. Edited June 19, 2009 by biohaz Quote
