Do Funny Cars have radiators?

They operate without radiators because they operate for only a few seconds at a time. A top fuel dragster might finish a run in less than four seconds. Then it’s time to rebuild the engine.

Why do drag cars not have radiators?

Many of the A/ND dragsters don’t use any coolant. The blocks are filled more for rigidity than anything else. The reason they can run without coolant is because they use alcohol and their fuel. The alcohol being sprayed thru injectors does it’s own cooling, plus they use up quite a bit of it making a pass.

How long do Nascar engines last?

Most production car engines are designed to last over 100,000 miles. NASCAR race car engines are designed to last one race (500 miles, in the case of the Daytona 500). While the same version of an engine is typically used for an entire season, it is rebuilt after each race.

What engine is in Toyota Nascar?

V8 engine. 4-speed manual transmission. Steel tube chassis with safety roll cage. Custom-fitted seat for each driver.

What engines do funny cars use?

The Funny Car’s key component is an 8.1-liter (496 cubic inch!) V-8 developing about 11,000 horsepower and some 8000 lb-ft of torque. Oh, and it is capable of revving to 8500 rpm. The engine is a development of the legendary 426 Hemi V-8, using a block and heads machined from solid aluminum billets.

How much does a Top Fuel engine cost?

The cost of a complete top fuel dragster engine is in the $58,000 range depending on options. The engine will be stripped down to the bare block after every run and be rebuilt in a span of 40 minutes. The engine will be torn down and rebuilt 184 times in a year if the car makes it to the finals at every race.

Do you need a radiator if you use methanol?

If running 100% methanol, on a track only car, a radiator is not needed at all. methanol burns cool, so it does not build heat like gasoline or even e85.

How long can you run a motor without coolant?

However, if you absolutely must start your car without coolant, it can probably run for about a minute without too much risk of damage. You may be able to get away with as much as 5 minutes of running without coolant, depending on the engine, car model, and how hard you’re asking the engine to work.

How hot does a Top Fuel engine get?

Exhaust temperature is about 500 °F (260 °C) at idle and 1,796 °F (980 °C) by the end of a run. During a nighttime event, the slow-burning nitromethane can be seen to extend flames many feet out from the exhaust pipes. The engine is warmed up for about 80 seconds.

Are dragsters automatic?

The answer is in the clutch. Unlike a street or high-performance car that uses a manual or automatic transmission, a top-fuel dragster uses a centrifugal clutch and only operates in forward, high, and reverse. … It is a system of timers, levers, and clutch discs making up a clutch pack.

How much air does a Top Fuel dragster use?

The fuel pump alone requires more horsepower to turn than the average street car produces. -With 3000 CFM of air being rammed in by the supercharger on overdrive, the fuel mixture is compressed into a near-solid form before ignition. Cylinders run on the verge of hydraulic lock at full throttle.

How much torque does a Top Fuel dragster make?

Its 1,000-volt, 5,000-odd horsepower motor might fall short of the peak power figures of the Top Fuel cars, but it’ll generate more than 17,000 pound-feet (23,049 Nm) of torque from zero RPM, has more “power strokes” per revolution, and should use its muscle in a far more controllable way than the combustion cars.
