VP Racing CHP PLUS Race Fuel

VP Racing CHP Plus is a leaded, oxygenated race fuel engineered for highly modified crate-engine racing applications. As VP Racing's ultimate crate engine fuel, CHP Plus is formulated to deliver additional horsepower and torque compared with VP CHP and MS109.

CHP Plus contains 18.34% oxygen, allowing properly prepared engines to burn more fuel and air for greater power potential. This high-oxygen formulation requires a highly modified fuel system, including a four-barrel carburetor, along with appropriate tuning. It is not a direct replacement for pump gas or a standard race-fuel setup.

For racers running a crate engine built for maximum competition performance, CHP Plus provides a high-energy fuel option with consistent chemistry for repeatable tuning. Its purple dye helps identify the fuel quickly in the shop, trailer, and pits.

CHP Plus 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 Plus race fuel?

VP CHP Plus is a leaded, high-oxygen race fuel formulated for highly modified crate-engine combinations. It is designed to deliver additional horsepower and torque compared with VP CHP and MS109.

How is CHP Plus different from VP CHP?

CHP Plus contains 18.34% oxygen, compared with 10% oxygen in CHP. VP Racing positions CHP Plus as its ultimate crate-engine fuel, designed to produce additional horsepower and torque when the engine and fuel system are properly modified and tuned.

Does CHP Plus require fuel-system modifications?

Yes. CHP Plus requires a highly modified fuel system, including a four-barrel carburetor, along with tuning that matches its high oxygen content. Do not use it as a direct replacement for pump gas or a non-oxygenated race fuel.

Is VP CHP Plus oxygenated?

Yes. CHP Plus contains 18.34% oxygen. Oxygenated fuel requires more fuel delivery than non-oxygenated fuel, so the engine's carburetion or fuel injection must be adjusted accordingly.

Is CHP Plus leaded?

Yes. CHP Plus is a leaded race fuel. Confirm that leaded fuel is compatible with your engine, fuel system, oxygen sensors, catalytic converter, and racing-class rules before use.

What is the octane rating of VP CHP Plus?

VP CHP Plus has a 99 MON, 115 RON, and 107 (R+M)/2 octane rating. Because it is highly oxygenated, fuel selection and tuning should consider the full engine combination, not octane alone.

Why does CHP Plus have a lower octane rating than some other race fuels?

CHP Plus is formulated around high oxygen content and power potential for a specific crate-engine application. Octane rating measures detonation resistance, but oxygen content, fuel delivery, combustion characteristics, and engine calibration also affect whether a fuel is appropriate for a given combination.

Why is CHP Plus purple?

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

Is VP CHP Plus street legal?

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