Without water, the antifreeze cannot transfer the heat from the engine.

I agree that NPG does absorb more heat, but since the cooling system is integral with the engine I can't see how it's really much of an advantage since the cooling passages are IN the block, so this heat energy can not be taken away from the motor. I've read all of the hype about actual engine (metal) temps being lower, yet when I ask Rob Golden and others if anyone has ever test rigged an engine with temp probes to get hard data, the subject always changes.
To me the biggest advantage of Evans is it's higher boiling point, the fact that you can run it near zero pressure, and its viscous properties which help eliminate air pockets in the system where localized boiling can occur. High temp spikes, increased coolant system PRESSURE on shutdown, and localized boiling are the main causes of o-ring failure in MOST turbocharged rotary engine applications (minus age) in my opinion. That being said, I still don't run it because of it's limited availability. To me distilled water, Water Wetter, and about 20-30 percent coolant (changed annually) is still the best solution.

How about this. Sewer water is H2O with **** right? Tap water is treated or fresh H2O right?
Therefore Sewer = Tap water and can be used for the same purpose.

No wonder you have terrible rep points.

Even more so since u can't mix water with it if ur cooling system happens to need a refill in the middle of nowhere?

So if I have boiling oil and splashes it all over your face, you won't feel any heat cause it ain't water and therefore can't transfer heat as every dumbass greasemonkeys know?

On the highway today, at 100F, my NPG+ temp rose to 109C with air temp at 50C. Car boosted to 1 bar and felt strong. The only difference is that when I turned off the car, the fan went full blast. Which isn't bad as I have the auxiliary electric water pump coming on.

I've accumulated more than 500,000 between my FC and FD over 15 years.
I 've had just about every coolant related problems known. The real bitch is when some little leaks happens and u find out half way to seven stock........ for example.

For those using ECU's such as the Power FC, at a reading of 100 degrees Celsius, the ECU's "logic" kicks in extra fuel to help "cool" the combustion temps and help to lower coolant temps. The stock ECU does the exact same thing. There's no real way to control it on the PFC, even with the Datalogit. There are several functions the ECU will not relinquish full control of. Idle mixture being the other (just ask anyone with 850cc primaries!)

I got both Sierra and NPG+ MSDS's, here are the ingredients:
Sierra:
Propylene Glycol 94-96 %wt
Water 3 %wt
Proprietary Additives 1-3 %wt
Evans NPG+:
Ethylene Glycol 66–70%
Propylene Glycol %not provided
Water %not provided but from Evans info it should be <3%
Proprietary Corrosion Inhibitor Package <2%
Do you all like me now??
I know I started something with this.... everybody will want to mix their own forgetting about the propietary additives saying "bah 2~3% is nothing"
:start sarcasm:
3 gallons of undiluted Prestone
1 gallon of undiluted Sierra
Since the coolants already have some water and additives then it should be the same right?
:end sarcasm:

actually I DON'T think it's snake oil. They found a blend of glycols and PROPIETARY additives that provide the properties they advertise. I use it on my FD and I have extra just in case. Running with no pressure and keeping rock solid temperatures without boiling, corrosion or having to change it ever are the benefits I love about it.

Sorry to disappoint you as I have done this driving on 101 on the way home. Checked my knock level and it's under 50 with datalogit.
And I still haven't mounted my Aquamist yet.

If you're going to make **** up, at least keep the **** straight. And how the hell do you get 500K b/w two cars? 400K on the FC and 100K on the FD?

I have come to the conclusion that this forum has served its purpose for me. The last time I got anything useful was when this guy installed an auxiliary electric water pump on his FD. Oh, that was me. Well, what about that time when the guy installed JimLab bushings and found out that they groaned like a wooden frigate. Oh yeah that was me.
BTW, the **** for bushing that Jim sold to me he does not have on his cars: his car runs custom machined steel bushings. We get second rate plastic and he uses steel. Great product endorsement eh?
In fact, checking the posts on the 3rd gen forums, I find nothing but JimLab and his arrogant I have more money than you attitude. At some point they were funny and interesting but it's the same tired old attitude. Jim, try hanging out with people who have more money than you rather than those who are less fortunate than you are just so you can stroke yourself to sleep every night.
What I'm trying to say is that it's time for me to go the way of Gordon Monsen: I'm looking to get either an Elise or a used 911GT3 and get out of the RX7 entirely - the **** is getting old.
