Sorry to see you go. You could have spearheaded the class action lawsuit against all these companies and their false avdvertising; Reduces Coolant Temperatures Extensive testing confirms Purple Ice™ reduces coolant temperatures better than comparable products while providing extra corrosion protection. For example, the average operating temperature of a 350 c.i.d. V8 engine (equipped with 160° thermostat) when dyno-tested with different coolants are: A. Standard mix of water and glycol (antifreeze) 228° F B. 50 / 50 water / glycol mix with Purple Ice™ added 222° F C. Straight water (no corrosion protection) 220° F D. Water with Purple Ice™ added 200° F The 100% antifreeze was just to illustrate that any time glycol is added to the water the amount of heat it can absorb goes down. In other words, 1% glycol/99% water is already less effective than 100% water. So of course, 50/50 mix is worse yet. Oh well, it's nice to see someone who knows more than the National Radiator Association Engineers. LOL!
maverick1970 I have heard rumors of that stuff. Does it work as well as they say? Is it cost effective for most of us, or should we stick with water/anti from Wal-Mart? With the frequency that I change my coolant (at least 4 times this year alone), I probably couldn't afford the stuff. Every time I do a project/upgrade that invades my cooling system, I swap it just to be safe.
By the way stmanser, It looks like your thread was stolen. I am partially guilty. I am sorry. Hope you got some good info before it was lost.
I have read some interesting articles on the stuff but have not personally ran it. At $28 a gallon, I will stick with AF and Water. I just thought I would throw a wrench into the debate. :evilsmile Also stmanser I don't think the 19x27 radiator will fit into our cars without cutting into the frame rails and front crossmember. You may also need to trim the bottom of the core support. A 19x26 will go in with the crossmember trim.
Stmasner, Sorry for the hi-jack....LOL! I never had the guts to run the Evans stuff. Would seem kinda funny to have a temp guage read 275 degrees and be normal! I too will stick to the water and glycol. Yes, we need some glycol for street driving, but not because it lowers the temp over straight water (it increases boiling point, lubes pump, and protects metals). Don't let people pull the wool over your eyes with the lower temp myth. Belief systems are different from facts...it's unfortunate some people have a hard time telling the difference. Here's a neat excerpt from the National Radiator Association (NARSA): {Notice the first two sentences and the last sentence in the first paragraph. -155} Coolant Selection Water has a higher specific heat than an ethylene glycol or propylene glycol coolant mix. Therefore, it provides the best heat transfer performance in a cooling system. If a cooling system is marginal, that is, it only overheats on the hottest of days, then running with water as a coolant in the summer and an ethylene glycol or propylene glycol coolant solution during the rest of the year will probably solve the problem. Commercial coolant solutions provide cooling, anti-freeze protection, corrosion inhibitors to protect the metals in the cooling system, and a lubricant for the water pump. When running water as a coolant for maximum heat transfer, a product that provides a corrosion inhibitor and water pump lubricant should be added to the water. In terms of the relative heat transfer performance of ethylene glycol versus propylene glycol coolant bases, they are pretty much equal when mixes according to the manufacturers’ recommendations, usually a 50/50 water to glycol mix. Ethylene glycol coolant solutions provide slightly higher heat transfer performance over propylene glycol solutions at low coolant flow rates.
Water wetter. I got no opinion on the heat transfer rate of a rat's ass. (But anyone have a link?) But I figured I'd just throw in a tidbit about water wetter. Most racers use it because race tracks require it to get on the track, not because it makes their engines make ice. When there's a crash, that slippery glycol stuff is pretty nasty for whoever is coming along behind. Not that a puddle of water is going to make anyone very happy, I guess it's easier to cleanup without it in there.
Try www.wetratsass.com. Tell us what you find. If my wife finds out I typed that into Internet Explorer, mine is grass
its fine....i learned a little from the arguing..... i know water and antifreeze together works....less antifreeze(freeze being the key word....because we dont have freeze here int he desert) is better for desert temps.... water wetter is good.... and get a bigger radiator.... thanks
nope. http://www.wetratsass.com/ That's what I was after scooper, a good laugh. But it didnt' work. Maybe this one? http://www.shavedratsass.com/ And my wording was inaccurate on the water wetter. It's not that tracks require it, it's that they require NO antifreeze, and water wetter is an acceptable replacement.
Water wetter may be good but quite honestly I just tried it and it didn't lower my temp one degree. My car runs pretty consistent between 190 and 195. After adding water wetter it stays exactly the same. The guy at the performance shop I bought it from assured me I would drop 5-10 degrees. Oh well, I can live with 195.
Phoenix was 114 degrees the other day. I just laughed when I saw that. You can spend the entire week messing with your cooling system, and you just have to remember cars weren't made to run cool in 114 degrees!
