So Cal Suspension Posted December 5, 2012 Report Share Posted December 5, 2012 Domes will vary based on what kind of fuel you want to run, and what compression you are after. Of course there are tons of other variables, but if you're after a pump gas motor, you'll want a little larger dome. 20-21cc's. If you are okay with race gas, 17-19 depending upon your elevation, as well as other factors. There isn't really a textbook "This is the dome you need for this motor". All domes are interchangeable between Noss, Pro Design, and Chariot. Trinity uses their own domes which I would avoid. I pulled the head off of my Cheetah, and both domes were stamped with the same CC, but were two completely different domes. I am not sure about ModQuad.
