08shee Posted October 18, 2008 Report 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
278 Posted October 19, 2008 Report Posted October 19, 2008 Depends on what your compression and altittude are Quote
08shee Posted October 19, 2008 Author Report Posted October 19, 2008 Depends on what your compression and altittude are Stock compression... 120ish on both cylinders. My altitude is 800ft. Quote
Wildcardracing Posted October 19, 2008 Report 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
