VP Racing CHP, short for Crate Horsepower, is a leaded, oxygenated race fuel formulated to maximize performance in crate-engine racing. Compared with premium pump gas, CHP can deliver 15 to 20 additional horsepower when the engine and fuel system are properly prepared for its oxygenated formulation.

CHP contains 10% oxygen, which allows the engine to burn more fuel and air for increased power potential. Because oxygenated fuel requires a richer air-fuel calibration, racers must modify and tune the fuel system before using CHP. It is not a direct pour-in replacement for pump gas.

For crate-engine racers seeking a significant performance gain, CHP offers one of the strongest horsepower-per-dollar upgrades available. Its leaded formulation and consistent chemistry support repeatable tuning in circle track, road racing, rally, and other competition applications.

CHP is purple for quick identification in the shop, trailer, and pits. It is available in 5-gallon pails and 54-gallon drums for off-road and competition use where permitted.

Frequently asked questions

What is VP CHP racing fuel?

VP CHP, or Crate Horsepower, is a leaded, 10% oxygenated race fuel formulated for crate-engine racing. It is designed to increase power potential beyond what premium pump gas can provide.

How much horsepower can CHP add?

When the fuel system and engine calibration are properly modified for CHP, VP states it can deliver 15 to 20 more horsepower than premium pump gas. Actual gains depend on the engine combination, carburetor or fuel-injection setup, ignition timing, and tuning.

Does CHP require fuel-system modifications?

Yes. CHP is an oxygenated fuel and requires fuel-system modifications plus appropriate tuning. Do not use it as a direct replacement for pump gas without adjusting the fuel delivery and calibration.

Is VP CHP oxygenated?

Yes. CHP contains 10% oxygen. Oxygenated race fuels require more fuel delivery than non-oxygenated fuels, so the engine must be tuned accordingly.

Is VP CHP leaded?

Yes. CHP is a leaded race fuel. Confirm compatibility with the engine, fuel system, oxygen sensors, catalytic converter, and the rules for your racing class before use.

What types of racing is CHP suited for?

CHP is intended for crate-engine racing and is listed for circle track, road racing, and rally applications. It is best suited to competition engines that can be properly modified and tuned for oxygenated fuel.

What is the octane rating of VP CHP?

VP CHP has a 101 MON, 116 RON, and 108.5 (R+M)/2 octane rating.

Why is CHP purple?

Purple is VP Racing's dye designation for CHP. It helps racers identify the fuel quickly and distinguish it from other VP Racing formulations. The dye does not affect fuel performance.

Is VP CHP street legal?

CHP is a leaded racing fuel intended for off-road and competition use where permitted. Follow all applicable fuel, emissions, and racing-series regulations.
