xXBANSHEE_KILLAXx Posted May 20, 2009 Report Share Posted May 20, 2009 ok, so i get everything about the cool head except the domes. What do they do?? why does it say 22cc domes, 18cc etc. What do those domes do?? What if your cylinder is stock and you put 22cc domes, do they add horse power or what?? I dont get it, someone help me out. And one last question, What do i have to have on my banshee in order to have a cool head?? :ermm: :shrug: Quote Link to comment Share on other sites More sharing options...

All you have to have done to your banshee is to have the old head off. Edited May 20, 2009 by Woolfman Quote Link to comment Share on other sites More sharing options...

xXBANSHEE_KILLAXx Posted May 20, 2009 Author Report Share Posted May 20, 2009 I have decided to buy one, but who makes the best cool heads out there?? Because i want to buy a good one that will last me. :shrug: Quote Link to comment Share on other sites More sharing options...
Woolfman Posted May 20, 2009 Report Share Posted May 20, 2009 (edited) Yes it does matter what size domes you go with if you go to small of cc you will need to run race fuel. Depending on your elevation you may be able to get away with 20cc domes that is what I have but I am at 4,000 to 5,000 feet. If you are at a lower elevation you may need to go bigger if you want to run pump gas. I run Pro Design I like it but you would need to get longer studs and Noss makes a good head and I think with it you can use stock studs. There are other good ones out there too don't really remember hearing anyone complaining about a crappy coolhead so don't know what ones to stay away from.

GrMeyer Posted May 21, 2009 Report Share Posted May 21, 2009 im going to say a shit load better then because you dont have to change the studs Quote Link to comment Share on other sites More sharing options...
dragbanshee98 Posted May 21, 2009 Report Share Posted May 21, 2009 o live in the northern corner of new york and i can get away with 18cc domes and run pump fuel... my motor builder has a 4 mill with 230 lbs compression that also runs pump, and demolishes every class its in at that lol... i would say most of the time anything over 200 lbs you would have to run race fuel Quote Link to comment Share on other sites More sharing options...
GrMeyer Posted May 21, 2009 Report Share Posted May 21, 2009 how in the hell are you running that high of compression and on pump...at 155psi i go to 100LL. but then again im also in Phx Az and the highest pump we have here is 91. Quote Link to comment Share on other sites More sharing options...
AKheathen Posted May 21, 2009 Report Share Posted May 21, 2009 it all depends on the compression ratio and timing, and stock, the banshee timing ranges up to 17*btdc. as a rule of thumb, with near stock port timings, and up to +4, 150-160 psi, is a safe reading, but not definate. that's why you look for detonation durring a plug chop, though i doubt even half check :shoothead: Quote Link to comment Share on other sites More sharing options...
krss144 Posted May 21, 2009 Report Share Posted May 21, 2009 Arent those domes interchangeable? One day run 22cc for trails and then next day (if you have another set) pop in the 18cc or so and go back and forth? Obviously changing the fuel also?
