Default Coolant

I've heard in the years I've been racing, that coolant ( antifreeze) is not allowed in Drag racing. But in the NHRA rulebook, it is not in there. Is this just an unwritten rule or track specific? Doug in AZ 8)

I've heard the same thing. I think it applies to NHRA/IHRA events. Might check with your local track to see what they advise. Coolant is much harder to clean-up than just water.

Of the two IHRA tracks that I go to. Unless your running a street car, coolant is prohibited. All the racecars must have water only. Antifreeze is super slippery once it gets on the track. Water can simpy be mopped up.

Just an update, ran plain water with some water wetter stuff sold at Walmart that lowers the temp by 20 degrees .

Worked great even in 115 degree racing weather last summer.

( stock 425 , 24"x16" 1 core aluminum radiator, Flowkooler water pump disc, 180 degree stat, Ford Taurus 2 speed efan)

If the car is driven to the track it is allowed. I'm sure ther is some ET cut-off also

Straight water cools better than 50/50 coolant and water, but it has no freeze protection and no anti-corrosion properties. If you run straight water, be sure and put your car away for the winter properly.

The coolant mix also has a higher boiling point.

If running just water, I really would recommend distilled water.
While it's better for all engines (a valid reason for buying premixed coolant too), without the anti-corrosive additives, all the junk (minerals) in tap water would be more damaging.

Funny work story... My "Home Station" had a regular ole hose hooked up to the source of demineralized make up water to the condensate tank. Employees were allowed to use that water to wash their vehicles during there off time. Nothing beats DI-H2O for a spot free wash & we had the best water that could be had.

Every once in a while someone would get the bright idea to perform a radiator flush with the DI-H2O & then refill the radiator with DI-H2O.

If you had a fairly new vehicle this would usually be the end of the story. If the vehicle was an older one... After a few days the owner would often find that the radiator had suddenly sprung one to several new leaks.

That demin water is fairly unstable. It wants its minerals back and will strip them from your radiator. If there were any previous leaks that had been stopped with any of the Bars Leak type products, you were sure to find out.
