Blownyel93 Posted January 17, 2010 Report Share Posted January 17, 2010 (edited) Alright I have to ask this question because I think I might be over-doing it a little. I have a stock stroke stock cylinder banshee with a cool head 17cc domes and vito's super stock piston. I put a compression gauge on it today and kick it a few times it goes up to 210PSI. Am I ok or should I go to bigger cc domes????????? I always run 110 race gas in my machine but just think the compression is maybe too high Edited January 17, 2010 by Blownyel93 Quote Link to comment Share on other sites More sharing options...
AKheathen Posted January 18, 2010 Report Share Posted January 18, 2010 the problem with domes that small, is the load on the crank. i wouldn't suggest running smaller than 18's on a stock, unwelded crank, and that is still pushing it. also, the higher compression will hinder the higher rpm power. 19's, 100oct, and a decent welded crank is your best bet at or near sea level. higher elevations can run smaller domes Quote Link to comment Share on other sites More sharing options...
jbooker82 Posted January 18, 2010 Report Share Posted January 18, 2010 Most builders shoot for 185 psi for race fuel. Small 17cc and 16cc domes are for people that ride at high altitude. Quote Link to comment Share on other sites More sharing options...
Blownyel93 Posted January 18, 2010 Author Report Share Posted January 18, 2010 Thanks I think I'll switch them out for a set of 20cc's just to be safe. Quote Link to comment Share on other sites More sharing options...
