bansheelover Posted November 18, 2003 Report Posted November 18, 2003 im looking into gettin a set of noss heads with domes. i dont want to go crazy with race gas or anything like that so 21cc domes should be okay right? I can still run just pump gas through those and my compression should be around 150?? Im trying to give my shee a lil low-end punch. Thanks Matt Quote
dlnoss Posted November 18, 2003 Report Posted November 18, 2003 Yes, 21cc domes allow you to run premium pump gas. You will notice a lot better power off the bottom. If you have other mods, like advanced timing or porting, or are above 1000' elevation it could change the dome size. Quote
bansheelover Posted November 18, 2003 Author Report Posted November 18, 2003 no i do not have any other major mods just tr-6's with proper jetting will it still give me the bottom end? Quote
dlnoss Posted November 18, 2003 Report Posted November 18, 2003 Yes, it will increase your bottom end power. I was asking about mods because, generally, advancing the timing by much makes you more likely to detonate and porting can lower your compression. So unless you are above 800' elevation 21cc domes would be a good choice for premium pump gas. Quote
bansheelover Posted November 18, 2003 Author Report Posted November 18, 2003 thanks a lot thats all i needed to know youve been a huge help in my decision matt Quote
illboogie Posted November 19, 2003 Report Posted November 19, 2003 what domes should i use im at sealevel with a 4dgree key i also want to use pump gas 94 Quote
dlnoss Posted November 19, 2003 Report Posted November 19, 2003 21cc is as small as I would recommend for 94 octane, particularly with the timing advanced. Quote
bansheelover Posted November 19, 2003 Author Report Posted November 19, 2003 hey dlnoss how come when i order over the site, i put in my postal code but when i check out it doesnt recognize it?? it is because its a canadain code?? just wondering CUZ I CANT ORDER ANYTHING!!!! thanks Matt Quote
bansheelover Posted November 19, 2003 Author Report Posted November 19, 2003 also , do u reccomend advancing the timing considering i am bone stock other than pipes and possibly a set of heads?? if so, how much?? between sea level and 1000' 280 main, stock pilot no port work done thanks Matt Quote
dlnoss Posted November 19, 2003 Report Posted November 19, 2003 Matt, The 'shipping' part of the web site doesn't know how to calculate shipping to Canada. It usually costs about $15 to UPS to Canada. I'll PM you on how to pay with the BansheeHQ discount. Advancing the timing is a inexpensive way to gain some performance. I don't know exactly how much it increases the tendency to cause detonation but I know it does some. I usually recommend the next larger size dome if someone is running advanced timing to be on the safe side. With pump gas, I would stick to 21cc domes under 1000'. You can use 20cc domes and may be fine but I try not to recommend something that MIGHT cause problems. -David Quote
