ERC A-19A and A-19K Racing Gasolines are predominantly paraffinic in character, containing a small highly concentrated high quality aromatic fraction. They are custom blended in smaller quantities and are intended for normally aspirated engines.

These blends produce higher bomb calorimeter readings commensurate with higher heat values per unit weight. Blending stocks were chosen with high hydrogen/carbon ratios and elevated resistance to heat and pressure as the main criteria. Fuel mileage with these blends is poorer than with higher density fuels; and in order to achieve proper airfuel ratios, additional fuel flow is required.

Power increases on the order of 1.0-2.0% o/c are typically reported with these blends.

ERC A-19A and A-19K are recommended for normally aspirated engines used in drag racing, circle track racing and other short duration events in which RPMs are usually elevated and cooling system capability is more than adequate. ERC A-19A and A-19K are not recommended for supercharged or turbocharged engines, use in air-cooled engines (with some exceptions), or any other application where a gasoline with high convective cooling coefficient is required.
