Banshee_LE Posted March 3, 2005 Report Posted March 3, 2005 (edited) I was wondering if I buy a Noss Head what kind of dome should I put in? I don't want to run race gas and i'm about at sea level. My modd are in my signature, also will that add any stress to my motor. I mean my motor is stock (cylender, crank...) Could that cause any problems, I just want more power without changing internal part in my motor. Oh and do I need to rejet? Edited March 3, 2005 by Banshee_LE Quote
banshdog Posted March 3, 2005 Report Posted March 3, 2005 I'm pretty sure that you dont wanna go any smaller than 20cc domes with pump gas. But wait for dlnoss to chime in to get the answer. Quote
RNBRAD Posted March 3, 2005 Report Posted March 3, 2005 Your better off running a 21cc dome than a 20cc at sea level. You will be right at the compression with the 20"s where at least a 50/50 mix should be used. To play it safe run the 21's. Quote

To play it safe run the 21's. 332771[/snapback] You are exactly right...I run a Noss Head with 21cc domes (at sea level) and on a fresh top end I'm right at 160 psi. If I were to use my 20cc domes, I'd have to run race gas or a mix. Quote
NEVER SATISFIED Posted March 3, 2005 Report Posted March 3, 2005 (edited) i just ordered a 19cc and im at 500 above sea.... i will have to run race gas. i spoke to david at noss and he said if i ran the 20cc and didnt advance my timing i should be ok but at some spots like glamis i would have to run 50/50. to play it safe go with the 21cc its universal to altitudes. although according to david at noss you will feel a huige difference using a 20cc or a 19cc rather then a 21cc.. but its what ever you PLAN on doing in the future. it doesnt stress the motor like the crank or the rods giving that you provide a higher compression. but of course you are going to putting a lil more stress on the motor but its not something that will break after a few runs... i say go for a 20cc and sacrifice some race fuel 50/50 and hang on.

dlnoss Posted March 3, 2005 Report Posted March 3, 2005 I just answered your email. 21cc domes are what I'd recommend for sea level and premium pump gas. Quote
