This stuff says it's legal for AMA road racing, but would it also be acceptable for NHRA / IHRA events? I don't know if the same cleanup issues that ethylene glycol has also applies to propylene glycol, although I've read they're very similar in chemical composition. If this stuff isn't track legal, I'll just keep using 100% distilled water w/ Redline Water Wetter.

I can't find anything for product reviews, but at a blow-out price of $3 / 64 oz container (and I bought the last 12 the shop had on the shelf), I figured I could afford to pick it up, even if it was just helping out my friend to get rid of inventory before closing the doors for the last time the next day.

When they ask me if I have anti-freeze in the car I just tell them that there is no ethylene glycol in the car I did contact the tech guys at E-town about it and they were not familiar with the stuff. They did say as long as it does not clean up like anti-freeze it would be ok. The stuff will dry on your hand with no residue. PRH446 10.084 @ 135.21 mph N/A through chambered mufflers,3300lbs.

I run a zero or 7 lb cap. IT never a boils over, cools faster than water alone. to start with your system must be 100% water free and in many cases air bleeds installed in your water pump or area to purge any air from system. If you have an oil cooler that keeps oil at or below 200 degrees you can let the coolant temp rise to 250 and not have any reason to be concerned.No worrying to boil over at all. home of the Sox and Martin Hemi Duster

It's quite a bit diff than your run of the mill ethylene Glycol (standard anti-freeze). Its bound to be pretty safe. Its not as greasy either, I would imagine it would be more easy to clean up.... just a guess though [color:"red"]65 Hemi Belvedere coming soon [/color] [color:"#00FF00"]557" Indy engine 1.07 60ft 144mph in the 8th 2100 lbs package [/color]

Now our NPG+ and NPG-R coolant are a blend of ethylene and propylene and will probably not be allowed due to the EG in it. The NPG comes in a white bottle and is a blueish/purple color. Our other coolants are clear to light amber in color. home of the Sox and Martin Hemi Duster

Our other coolants are clear to light amber in color. I think that's some information they should provide on their website. I just did quite a bit of reading and didn't see anyplace that said the NPGR has ethylene glycol in it. I understand that not all racing organizations have the "no EG" rule but the racers still should be made aware. Also, I see they make water pumps but didn't see one for Mopar. Bad on them! All that said, I like the theory and might try some of the blue stuff.
