Performance with pump gas is what matters to most consumers. With today's modern technology, the definition of "street car" and the performance possible with 93 octane has changed dramatically in recent years. Advances in supercharging technology mean that the need for racing fuel is now largely limited to those campaigning actual race cars. This also means that full power is always available, not just when a customer has racing fuel in
the tank.

While the performance of the ProCharger/Super Chevy Project Nova has been spectacular, dealers and engine builders are now raising the bar even further. A ProCharger dealer recently produced 1685 horsepower with a modified 580 cid motor and a single modified 850 carburetor, running an Intercooled F-2 ProCharger and 93 octane pump gas (see dyno sheet, below). Another dealer recently produced over 1650 hp with pump gas and a single carburetor, also running an Intercooled F-2 ProCharger.

This performance also makes it clear that technological improvements have substantially increased the power possible with a single carburetor, as well as the power generated by a 10.5" compressor such as the F-2. This second issue is further illustrated by the 9.75" F-1R ProCharger, which outperforms 12" compressors from competing companies. The first issue helps simplify and lower the cost of high performance by increasing the power level at which a carbureted engine must utilize twin carburetors.
