BeJay Posted February 21, 2005 Report Share Posted February 21, 2005 Ok right now i have 22cc domes and I am buying new domes and i need to know is there a big difference between 18 and 19cc. I was told buy someone that if i was to buy 18s that i would have to run race fuel but i want that higher compression? any suggestions would be great!!

dlnoss Posted February 21, 2005 Report Share Posted February 21, 2005 Unless you are at a pretty high elevation, you will probably need race gas with either size. What is your elevation and other mods? Quote Link to comment Share on other sites More sharing options...
Tim C Posted February 21, 2005 Report Share Posted February 21, 2005 (edited) Check this out: http://www.thebansheezone.com/Bansheezone/CoolheadChart.htm This chart is for an engine with NO PORTING Anymore then about 150-160lbs will require race gas Edited February 21, 2005 by Tim C Quote Link to comment Share on other sites More sharing options...

racer Posted February 22, 2005 Report Share Posted February 22, 2005 how come there is such a HUGE difference in between the Noss chart and Meat's chart? i just now noticed it and Meat's is on the low side. That could be disasterous. Noss Chart Meat's Chart Quote Link to comment Share on other sites More sharing options...
dlnoss Posted February 22, 2005 Report Share Posted February 22, 2005 Actually, my chart is on the high side. I will probably change it. I've left it that way to stay on the safe side and get people to ask in case there are other factors like timing and stuff. Quote Link to comment Share on other sites More sharing options...
