08shee Posted October 18, 2008 Report Share Posted October 18, 2008 My banshee has toomey t5's, k&n pods w/ no airbox. I've been reading about advancing the timing with an aftermarket timing plate. Can I just advance the timing and keep using 91 octane fuel? Quote Link to comment Share on other sites More sharing options...

Wildcardracing Posted October 19, 2008 Report Share Posted October 19, 2008 You should be safe with +4 on 91. However, you should pay close attention for signs of detonation...ie: spark plugs backing out, silverish specs on your plugs or overheating Quote Link to comment Share on other sites More sharing options...
