hello

i have a question about using 100% methanol as fuel and running a 13b turbo engine.
what type of rotor (cr) is the best way to go with methanol and turbo? I can choose from 8,5:1 to 9,7:1....

i`ve seen piston guys using meth+turbo with a cr up to 16:1...

so i need a bit input please...

 

you can use anyone of them, I would go with 9.0:1

 

+1 Any of them would work but most people I've seen at the race track run S5 T2, Rew, or Cosmo which all are 9:0:1. But I've seen high compression rotors on high boost as well be used.

 

Many of the high-hp engines will run S4 rotors. The nice part about the S4 T2 rotors are that they have thicker casting on the rotor faces, which will hold up a little more to detonation (without denting) than the S5/REW rotors. Plus they can be lightened and balanced to S5 weight.
