Me and my buddy both race. And we both have very similar builds. Stock bore and stroke. 13.5 to 1 piston. We both have port work in the heads. And we are both running a stage 3 hotcam. Now currently we run 93 with vp octanium. And we try to get the number around 101 octane. Give or take. We've been discussing mixing fuel and or swapping fuel. Most of the guys we run with run MR12. But it's extremely expensive. We did discuss possibly mixing MR12 and pump gas. Or possibly looking into mixing a different type of fuel with pump gas. Looking to see if anyone here has a similar setup. Or has any advice on what direction we should go. We race at a local track. And do some trail riding. We're hoping to find something we can mix with 93 preferably. But we're not opposed to switching fuels either. Any advice would be appreciated.
