What type of fuel do drag racers use?
Rather than gassing up on regular fuel, drag cars use a mixture of high nitromethane, which vastly reduces the amount of oxygen that is running through the engine at such high speeds.
What octane is drag racing fuel?
Sunoco Standard is the most common choice as an entry level race fuel. Like all our race fuels, Standard is extremely stable and consistent. 100% gasoline, this leaded fuel offers 110 octane and can be used in carbureted applications from dirt bike to drag car.
What is the best fuel for race cars?
Most race car drivers prefer fuel that is methanol- or ethanol-based, and the reason is simple, really. Overall, alcohol-based fuel has a high octane rating which increases fuel efficiency. Methanol burns cleaner and cooler, is less flammable, and less expensive than gasoline.
What is the highest octane race fuel you can buy?
The gasoline at a gas station ranges from 87 to 93 octane. Racing fuel ranges from 100 to 120 octane.
What gas does Top Fuel dragster use?
Powered by a supercharged and fuel-injected 500-cubic-inch adaptation of the famed Chrysler Hemi engine, Top Fuel dragsters can burn up to 15 gallons of nitromethane fuel during a single run. ”
Can I mix race fuel with pump gas?
Yes, you can mix ethanol based 93-octane pump fuel with race gas. To be above 100-octane, mix it 50:50.
Can you run race gas in a stock motor?
You can put some racing fuels in normal cars, but there is no real reason for you to do this. These fuels have higher octane ratings, so are designed to perform at higher temperatures and pressures. There is generally no noticeable performance gain when they are used to fuel consumer vehicles.
What do Indy cars use for fuel?
Today the IndyCar Series is using a variation of E85, which contains 85% ethanol and 15% high- octane racing fuel, which delivers an octane rating of 105. So it can be seen that the fuel for an IndyCar is significantly higher octane rating that gasoline we buy from the pump.
What is the best fuel for drag racing?
Fuel mixtures for drag racing and most other forms of racing are run a lot richer, especially with mechanical fuel injection. When paired with higher compression and/or higher boost, more enrichment of alcohol fuels can retard detonation or overheating.
What kind of air pump does GZ motorsports use?
These pump designs do pump a lot of air, the trick is making their sealing system reliable, which GZ Motorsports has solved. For example, the IHRA Pro-Mod and some IHRA Pro Stock racers run a modified 3-vane Ford pump that outperforms any of the current aftermarket pumps.
Why is fuel enrichment important in drag racing?
For gasoline or alcohol fuels, that value represents only the amount of air and fuel that burns. Fuel mixtures for drag racing and most other forms of racing are run a lot richer, especially with mechanical fuel injection. When paired with higher compression and/or higher boost, more enrichment of alcohol fuels can retard detonation or overheating.
How much vacuum in crankcase for drag racing?
I think 15″ is fine in a drag race application because the engine is at that RPM for such a short period of time. We highly recommend installing a vacuum relief valve that mounts to your valve cover and can be preset between 12″ and 20″ of vacuum. How should you measure the vacuum in your crankcase?
