I've read that methanol can be more prone to preignition than gasoline at stoichiometric correct mixture.

Pre-ignition is far more damaging than detonation. It strikes faster than you can respond to it. Keep in mind diesel motors run in detonation continually.

Pre-ignition can have you lighting off before BDC and trying to compress burning mixture. EGT soars and piston looks like plasma cutter was in it's place. Total meltdown before a full revolution has completed. Been there done that.

About Us

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
