jbooker82 Posted June 30, 2008 Report Share Posted June 30, 2008 The pipes are about the only thing that will affect compression. They probably wont affect it enough that you will notice it when kicking it over. When it is running that is when they will affect the compression a little. That is why 2 stroke pipes are shaped the way they are. Quote Link to comment Share on other sites More sharing options...
LIM_Whiteboy4life Posted June 30, 2008 Report Share Posted June 30, 2008 No, What will affect (effect) (w/e) compression is milling down a stock head, smaller (more) or larger (less) CC domes for a cool/noss head, Porting ( amount of work done and what type of port it is affects in diff ways ) and engine wear will cause compression to decrease....

05.Banshee.SE Posted June 30, 2008 Author Report Share Posted June 30, 2008 This is going to be the list of mods: -K&N Pods w/ outerwears (remove stock airbox) -T5s -TORS Removed -VForce 3 Reeds w/ cage -Jetting -NGK Iridium Plugs -PD Cool head -21cc domes -Adj. Timing Plate +4 I guess my compression will be in the 156 range... (Although I won't know for sure until I actually do it all and check it.) Main reason for me asking was I wanted to see how far I'd be push to use race gas once I get everything installed. I don't want to...but if 150 is the suggested cut off, I guess I have no choice.

Wildcardracing Posted July 1, 2008 Report Share Posted July 1, 2008 150 psi is about the limit for pump gas. I've seen people get away with a little more. Air filters and pipes will have no noticeable effect on static (cranking) compression but will effect the actual compression a little when the engine is running because they will allow more air into your cylinders.
