How many #'s of boost are you running and what is your compression ratio? Also what altitude are you running at?

Did you advance your timing much?

15 to 20Lbs, I do not think 100LL is even close to enough, you will probably need C12 or C14 and need to retard the timing a bunch. You could try it but if it starts to detonate it could cost ya $$$$$.

Is your machine up and running? If so what are you running now? Also what injectors are you running?

Another thing you could consider is water/methanol injection, some people prefer this over race fuel but it also adds another tank and system to maintain. Not sure what the stock rods will take you might want to upgrade to aftermarket rods. Also check with MCX to verify their turbo is still in its map @ +11 Lbs. These V Twins require a lot of air @ the RPM's we spin. You might have to upgrade the turbo if you want to run that much boost. Also you should upgrade to forged pistons (if you haven’t already).

To answer your original question, I would recommend 100LL @ anything over 10LBS. Might be over kill but would be cheaper than destroying a motor.

well most of mcx kit run 11 pounds on stock engines on pump gas i have been running that for over 800km and i have upgraded the rods already. I think i am going to just run it at 15pounds with av gas to be safe cant see that being to big of deal
