As the name implies, antifreeze keeps the water in the mixture from freezing and has no real cooling benefit. Race cars are typically not raced in extreme temperatures therefore there is no need for antifreeze.
What do drag racers use for coolant?
Automotive antifreeze is typically ethylene glycol or its less toxic relative, propylene glycol. Both of these alcohols have lower freezing points and higher boiling points than pure water. While these are important qualities for street-driven automobiles, they are irrelevant to a dedicated drag race car.
How are Nascar engines cooled?
Probably very similarly to most auto engines…they use a water to air cooling system, with a radiator placed somewhere in the airstream to exhaust heat, and a water pump to circulate the fluid through block and head. And some form of temperature regulation like a thermostat.
Do drag cars run coolant?
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.
Is it OK to run straight water in radiator?
Running just water in your car’s radiator will guarantee overheating and damage, including to your cylinder heads and engine block. And most tap water contains minerals that will leave deposits inside the radiator, causing corrosion, shortening its life and further diminishing its ability to cool.
Can a car run on water instead of coolant?
Even though many people choose to simply put water into their radiators instead of coolant, it is not really a good idea. … While water does help to keep your engine cool, it does not work nearly as well as coolant does. First of all, water boils faster and at a lower temperature than coolant.
Is water wetter NHRA approved?
It has come to our attention that the NHRA is now allowing coolant to be used in Stockers !! .
Is Evans waterless coolant NHRA approved?
Evans High Performance Waterless Coolant is NHRA approved and allowed.
Why did Dodge leave NASCAR?
Despite designing a Gen-6 car, Dodge stepped away from the sport after Brad Keselowski’s 2012 championship. The American automaker pulled its support, unable to find a flagship team to replace the departing Penske Racing.
How long do race car 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.
Is running straight coolant bad?
Pure antifreeze-coolant doesn’t have the heat-transfer abilities that a mixture of antifreeze-coolant and water does. … Pure antifreeze-coolant isn’t nearly as efficient at getting the heat out of the engine as is antifreeze-coolant and water. Running on pure antifreeze-coolant will hasten your engine’s demise.
Why do race cars use distilled water?
Concentrated antifreeze instructions state to use distilled water, not tap. So, race cars can be designed to not run over boiling point and use distilled water (or other mineral mixture for anti-corrosion etc., and not boil over.
