How does methanol affect a drag racing engine?

  • “This is just a build up of methanol in the oil, mainly seen when the engine is rich,” Gower said. “Blown alcohol engines are run rich at idle to control temperatures. Fuel gets past the rings into the sump, and drag engines don’t run hot enough or for long enough to evaporate it out.”

Why is methanol used in racing engines?

  • Methanol has a number of positive combustion characteristics that serve the racing engine. A given amount of air can burn much more methanol at stoichiometric mixtures than gasoline, and maximum power on methanol is usually achieved at mixtures very rich of stoichiometric.

He said there are several reasons racers favour alcohol (of the fuel variety) and we got him to explain what racers should think about in considering methanol as a fuel. “Methanol has a strong cooling effect on the air coming into the engine, so if you can keep the intake temperatures down you can run a lot of compression and a lot of boost,” he said.

Methanol will burn without fouling or miss-fire to a very rich mixture. This ability is used to run rich or cooling when the boost or compression is very high. About 5 to 5.5 is typical for supercharged very high power engines.

This is what makes methanol such an effective fuel in forced-induction applications like turbocharging and supercharging, and it absorbs so much heat that an intercooler often isn't even needed. A...

Methanol has less energy content than regular gasoline, so vehicles get about half the mpg out of the fuel. But it has a higher octane. As the smart people at Hot Rod magazine explain, race-car engines are built to squeeze more power out of that less-energy-dense methanol, by adjusting the air-to-fuel ratio.

The performance-enhancing attributes of both ethanol and methanol were realized early on in motor racing. Blends containing methanol and benzene were often used in Grand Prix cars, especially as supercharging was developed as a tool to extract maximum performance from a given engine swept volume (and charge cooling was not widely used).

Racing engines on methanol are usually run on the rich side for engine response, a strong cooling influence, and good detonation resistance. Monitoring weather variables enables racers to maintain their fuel systems.

This means you’re burning almost three times more fuel per power stroke, resulting in increased engine power. Methanol absorbs more heat than gasoline, making it perfect for extremely hot-running supercharged or turbocharged engines. For these reasons, some racers and competitors lean toward methanol in their competition engines.

Methanol fuel is an alternative [biofuel] for internal combustion and other engines, either in combination with gasoline or independently. Methanol (C H 3 O H) is less expensive to produce sustainably than ethanol fuel, although it is generally more toxic and has lower energy density.For optimizing engine performance and fuel availability, however, a blend of ethanol, methanol and petroleum is ...

Methanol, methyl alcohol, or wood alcohol (CH3OH), is usually made from natural gas. It was first discovered in 1823 by condensing hot gases from the burning of wood. It has been the fuel for Indianapolis 500 race cars since 1965. Methanol has the ability to absorb water, even right out of the air.
