Hello everyone,

Dunno if this has been talked about before but i did a search but couldnt find the answer i'm looking for.

So, last year the drag race association here on the island joined IHRA and we got a lot of new rules and this year one of the new rules is that cars that are competing cant run with coolant that has glycol in it.

Is there any alternatives to coolant or any other types of coolant that doesnt have glycol in it? Because i dont really want to rely on just water to keep the engine temperature down.

Thanks in advance for the replies.

Take care

HI mate, water cools better than glycol anyway, it absorbs more heat for it's volume.

We run straight distilled water in the race car with a corrosion inhibitor. Castrol make the inhibitor I use but I am sure there are other brands available.

If you find you still need more cooling capacity, we also use redline water wetter which made the car run about 5-10o cooler.

I didnt know that water cools better than glycol, thats good to know. I had a look at the castrol corrosion inhibitor and the redline water wetter, both looks good. Gonna talk to my friends and see if they want to join in on a group buy so we can order some online.

Thanks for the reply Duncan.

BTW I should add that glycol does have a role....it adds the anti-freeze ability. When we are going to goulburn in winter we change back to coolant, the extra cooling isn't really important that time of year anyway

I just assumed that wasn't an issue for you in the caribeean but it might be for others reading :D

do u use the water wetter and corrosion inhibitor together?

like im asking if they are compatible together?

full bottle of each in each full colling system fill up?

i know that the redline water wetter has an inhibitor in it but prob not very much and and if your using de mineralised water i suppose it cant hurt to add the 200ml castrol inhibitor also?

I've never used them both together, when running the redline water wetter it has stuff in it already like you said. once again, i've never had a problem.

but be careful of sub 0 evenings...

Yea, thats not gonna a be a issue here in the caribbean. A good thing too otherwise a lot of people would protest against this new rule.

yeah the whole point of so called 'coolant' is that it lowers the freezing point so your liquid doesn't freeze up at 0 degrees C. like dunc said it doeasn't really help much with the cooling capacity it does raise the boiling point a bit but under 0.9-1.3 bar pressure (depending on your cap seat pressure) water's boiling point is increased a fair bit anyway. that's what stops is boiling in your engine, the pressure. under 1 bar atmospheric pressure plus the added 1 bar system pressure pure water will boil only at about 120C.

lol well if my car even got close to those temps id be sorting out a better cooling system.

i have found both my r33s have pretty good factory cooling systems (not talking about oil)

no matter how hot the ambiant temp is or how long im being hard on them, the water temp is pretty stable.

genuine thermostat, a regular cooling system flush and retaining clutch fan probably have a bit to do with that though.

more horsepower and thermo fans and water instead of coolant will be the test in the near future when car is back on the track

    • Hope you aren't too sore after that one, might take a day or 2 to notice yet and I guess it is a loooooong drive home. On the bright side, tube frame front end is a thing at superlap, right?

    • The chart of front pressure to rear pressure (with one being on the x axis and the other being on the y axis) is not a straight line on a typical proportioning valve. At lower pressures there is a straight line with one slope, and at higher pressures that changes to a lower slope. That creates a bend in the line at that pressure, called the knee point. If you do not change the proportionng as the pressure gets higher, you will suffer excessive pressure (at one end of the car or the other, depending on which way you look at the proportioning action) and then get lockups at that end. The HFM BM57, from my memory of previous discussions, is based on the BM57 from a different car (to a Skyline), with a different requirement for the location of the knee point and the distribution of pressure front to rear, and so is not a good choice for an upgrade on a Skyline. Here's a couple of links to some old posts, one from here, one from elsewhere. A lot of it pertains to adjustable prop valves, but the idea is the same. There are plenty of discussions on here about this issue from al the many years of people wanting a cheap/accessible option. https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/ https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/  
    • Yeah dunno why johhny posted that here with no context, just post on FB/insta bro where he put it up?  Laine had an off at T4 during Thurs prac, he's ok, car is less than perfect, they are done for the weekend, he can fill in the rest. Bando also binned it like 100m up the road.   
    • I feel there must have been a FB/insta post and the weekend did not start well at all I hope everyone is all okay
