    What does a normal boost/timing retard curve look like on methanol? Is there a point where you just stop pulling timing out?

    Do you limit the boost to 20psi or do you keep the timing at 26.5 for all boost levels above 20psi?

    Actually gets to 26.5 about 16lbs. 16lbs is my bracket setup and 20lbs is the "fast" setup. I'm probably leaving a bit on the table with the timing, but I do make a lot of runs and have had excellent reliability.
