Disclaimer: All of the following engine profiles cannot be guaranteed to work adequately right out of the box. In any of these engine profiles, jetting combinations were determined from similar running engine profiles previously analyzed with ProCalc. Spark plug readings and engine temperature measurements are needed from incremental runs. That is to determine if jetting […]
Adding nitro to a methanol racing engine is an easy way to make more power. Assuming a 50% mixture by weight, not volume. FYI: A 50% mixture by volume is 59% by weight which is a different setup. NORMALLY ASPIRATED The enrichment for a normally aspirated racing engine with moderate compression ratio (around 10.8 to […]
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 […]
