I would only use 3s on that sucker, with the Fan! I run mine currently on 2s only without the fan with 30 degrees timing cheat mode with the MMpro.

I would use the timing inserts and use the one with the lowest timing. Then on 3s use a smaller pinion to compensate for the goofy small rotor, but make up the speed with the use of cheat mode, boost or Turbo....anything that increases timing at a certain rpm range.
