You can theoretically run up to 57% methanol blended with ethanol and gas while still maintaining an E85 AFR. The ethanol acts as a co-solvent. (Typically, mixing gas with methanol in 50-50 type blends results in an oily looking mess because gas an methanol do not mix well on their own.)
Why does racing often choose methanol as fuel?
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.
Does Nascar run methanol?
NASCAR engines burn 110-octane leaded gasoline. Indy cars burn pure methanol (a.k.a. wood alcohol, CH3OH). Top Fuel dragsters and funny cars burn nitromethane (CH3NO2).
What’s the difference between M1 and M5 methanol?
With its upgraded combustion additives, M5 will make more power than M1, meaning 5-7% more power than standard methanol, while still offering better protection against detonation. Like M1, M5’s improved vaporization offers a wider acceptable range of air/fuel ratios and tuning, as well as faster combustion speeds.
What octane is methanol fuel?
Methanol reported as having an octane rating of 133 (RON) and 105 (MON), with a combined octane rating of 119 ((R+M)/2). In contrast the combined octane rating of regular gasoline is 87 and that of premium gasoline is 93.
Can you run methanol in a street car?
Methanol has come back in a big way, with many race cars making the switch and even some street vehicles running the stuff. In the case of methanol, an air-to-fuel ratio of 4:1(4 parts air to 1 part fuel) is considered slightly on the rich side, but will allow the engine to make its maximum power.
Can I run methanol in my car?
Because it has a richer air/fuel ratio than gasoline, running methanol means reduced fuel economy. It’s also very corrosive, and can eat through fuel lines if left sitting. For racing, however, methanol makes for a very good fuel, so expect to see more of it at the track near you.
How many miles per gallon does a NASCAR get?
The NASCAR stock cars of the XFINITY and Monster Energy series average in the neighborhood of 4.15 miles per gallon, according to one of the company’s calculations.
What octane is methanol?
What octane is M1 methanol?
VP 1804 M1 Methanol 111 Octane Racing Fuel 54-Gallon Drum.
Can you mix nitropropane with gasoline?
While nitromethane (CH3NO2) does not mix with gasoline, nitropropane (C3H7NO2) does. According to Dr. Hill, “Mix about 10 to 20 percent nitropropane with good gasoline and you make some power!” It was that line that inspired me to find out just what this stuff was worth.
Is methanol a good fuel for racing?
Ironically, in the pre-war days of Grand Prix racing, methanol was frequently used as a fuel, so to some extent, the wheel has turned full circle. Methanol is safer but can it give the ultimate performance? Sometimes a motor racing body insists that methanol alone is used – for example US motorcycle speedway uses methanol only.
What is the purity of M1 methanol?
Product Description M1 Racing Methanol has a 99.95% minimum purity – the highest purity available in the U.S. Compared to standard methanols, M1 engines run cooler and are less subject to corrosion. VP uses only lined drums which prohibit rust, corrosion and metal deposits that can contaminate fuel delivery systems.
Why do Indy cars use methanol fuel?
The US Indy Racing League (IRL) shifted to using methanol as its fuel in 2007, before switching again to ethanol E85, partly because of a sponsorship deal with a Brazilian ethanol group. However, in the Indycar design teams, the race is on to develop an engine that can deliver up to 900hp, and that means motorsport fuels that are methanol-based.
Why is methanol bad for your car?
Methanol has a lower energy content than petroleum. This means that a car only gets about half the mpg out of methanol. However, while that might not be great for the school run, racing car engines are designed to get more power out of the methanol by altering the ratio of air to fuel.
