The enrichment for a normally aspirated racing engine on methanol is around 15% excess fuel over the stoichiometric (best burn) amount.

The enrichment for a supercharged racing engine on methanol with high compression ratio wedge head is around 65% excess fuel over the stoichiometric (best burn) amount.

The enrichment for a supercharged racing engine on methanol with high compression ratio Hemi head is around 85% excess fuel over the stoichiometric (best burn) amount.
