Certain individuals prioritize enhancing fuel efficiency, while others focus on lowering exhaust emissions. However, there exists a unique group of individuals, the adrenaline-fueled thrill-seekers, who aim to maximize horsepower and torque from their engines. Frequently, they find themselves compromising on fuel efficiency for increased engine power, but this doesn’t always have to be the situation…

Dosing your vehicle with FEROX or 801 RACING can help you get the most out of your fuel, resulting not only in increased fuel economy and decreased emissions but in enhanced engine output. These increases in peak horsepower and torque can put your engine ahead of the pack.

Our specialized solid fuel combustion additive contains a proprietary combustion catalyst that provides a more complete burn of your fuel. In technical terms, the catalyst has a chemical affinity to the hydrocarbon molecules in your fuel and achieves a positive effect on the rate determining step in the combustion process. Simply put, more fuel gets burned in the engine for energy as opposed to contributing to exhaust emissions and carbon deposits.

RENNSLI fuel catalyst additive formulas are suitable for a wide range of applications, from standard cars and race cars to semi-trucks, offering various benefits due to enhanced combustion. Both FEROX and 801 RACING formulas deliver identical advantages; however, the 801 RACING PULSE POWER BOOST offers more instant measurable boost in horsepower, improved overall performance, ensures smoother cold starts, enhances throttle response, and reduces knock under load for diesel, gasoline, and methanol-powered internal combustion engines. Our formulas do not alter any specifications of any type of fuel and are safe for use in street, racing, or off-road vehicles.
