Solefate Posted September 15, 2017 Report Posted September 15, 2017 Hey guys, I've got a very lightly ported stock cylinder banshee with fmf pipes and athena cool head. At about 1200 feet. I can get 91 pump gas where I live and would like to stay on that instead of needing race mix. What size domes are bare minimum for this, and what size is safest? Quote
Ayesully810 Posted September 16, 2017 Report Posted September 16, 2017 Can u get ur hands on some 93 octane? They pump that there whete ur at? Id imagine 23cc domes should put you around 140 psi If ur gunna run 91 130 psi would be safer. 93 all day though if u can. Always be sure to do a compression test after a dome swap to be sure Sent from my LGMS210 using Tapatalk Quote
trickedcarbine Posted September 17, 2017 Report Posted September 17, 2017 22-23 CC should be decent. Maybe go 23 and some timing. Quote
Yeepo Posted September 28, 2017 Report Posted September 28, 2017 Who sells 23cc domes for stock cylinders? Cant find them anywhere, all I see is for big bore cylinders. Quote
