FYI FORD MustangSteve's Ford Mustang Forum / Antifreeze from VP

Anyone have any experience with the Stay Frosty antifreeze from VP racing? They have a high performance one that is good for street cars. They also have a race version of it as well. Was doing a little research and it sounds like an awesome product but not cheap.

Nope, but IMO trick antifreeze is a waste or money. In certain vehicles it may make sense to go to a waterless coolant like Evans or Meca, but in a street car that gets driven regularly your best bet is regular old green antifreeze 50/50 with distilled water and change it every 2 years.

What’s wrong with good old Prestone, that all I’ve ever used for over 65 years.
Matter of fact I did a flush and fill a while ago, pita getting rid of the old stuff.

Not saying anything is wrong with the old green stuff. Just looking to see if there's anything better out there. I haven't started with a new fresh cooling system in a very long time. Just want to make sure I select the best option.

Reading the VP description it appears to have better anti corrosion properties but that could just be their sales pitch in their own description of the product.

No offense intended but you're overthinking this. The green stuff is thoroughly proven. The keys are using the correct mixture (50% antifreeze and 50% distilled water) and proper maintenance (changing it periodically).

I do plan on taking the mustang to the drag strip and if ever possible I would love to drive it at Sebring.

Looks like their race version is glycol free, that is good when you're at the race track. You'll get, at the very least, yelled at if your car barfs antifreeze at the track so there are a lot of alternatives out there. Some folks just run distilled water at the track and then replace it when not at the track.

Most tracks are going to tech your car and require you to have an overflow bottle. I've never had a problem with a car overheating at the strip. You typically are not running it hard enough for long enough, unless you're really hot lapping it because there's no one there. Normally you make a pass and then will have to wait 10-60 minutes to make another. Usually you have to run the car between passes to ensure it stays at operating temp from my experience.

Road courses are different. But with lots of air flowing through the radiator if the cooling system is new I couldn't see an issue cropping up. If it doesn't overheat on the street I doubt it would at the track. I never had an issues years ago when I used to run SCCA events.

Most tracks nowadays will not let you run with antifreeze simply because it's a PITA to clean up. Whether or not you have antifreeze is not something tied to safety equipment, it is a track choice.

Wait now.....what !?? Don't chew live in Flar-duh ? Do they even sell antifreeze there ?!
Do you leave the Mustang parked outside in the weather (I think I know the answer to this 'un !)
I'd do distilled water with just a 'dash' of glycol to provide lubrication. (use what ever is the cheapest....glycol is THE ingredient in most brands of antifreeze)
Butt datz just me...

Yep live in SW Florida. It occasionally gets below 50 during the winter months. 😁

I believe you've been to Cecil Country Dragway in MD, which is my local track. Not too concerned about teching the vehicles (one reason I won't go on Friday nights anymore, someone's junk always blows up and shits the track down for an hour)

SCCA stuff I ran was typically just in parking lots with cones.

Good to know some tracks have actual rules

Cecil is where us Lightning guys have Spookfest (play on Halloween), won't be going this year because all my stuff is is pieces. A good buddy of mine lives just down the road from Atco, so sad it closed.

Yeah, I had a buddy that used to race at Atco. Sad when any track closes. We went to Englishtown a couple times in NJ. Pretty good track, but the tech guys there are a little insane. Overall I like Cecil County. The trick is go Wednesday nights, not Fridays. I'm going to try and get my F250 there for some passes in the spring and take my kids.
