RUDEDAWG Posted January 3, 2008 Report Share Posted January 3, 2008 It all depends on your elevation and fuel octane, Noss's website has a chart at the bottom of the page. If you still aren't sure just e-mail them and they will recommend the best domes for your particular setup. Quote Link to comment Share on other sites More sharing options...
jet mech Posted January 6, 2008 Report Share Posted January 6, 2008 Just F.Y.I. I went with the 20cc domes due to a conversation I had with a fello BHQ'er he said that the stock cranks can't handle to high of compression enless they are trued and welded, don't know how much truth is in that but I am not one to find out things the hard way, 20cc domes put me at 158psi a side at 1100 ft and that was a bit higher than the chart Quote Link to comment Share on other sites More sharing options...
jbooker82 Posted January 6, 2008 Report Share Posted January 6, 2008 I ran my banshee at 155 psi with timing set at +4 deg on 91 octane fuel on a non welded crank. If your going to be running straight race fuel and have a compression of 185 then I would highly recomend welding the crank. Yea if you want to pull the crank out and have it tured and welded it is good to do but not a must. Quote Link to comment Share on other sites More sharing options...
