for my good friend -----
ref: June 2009 issue of Heavy Duty Trucking magazine, page 92, editorial by Steve Sturgess, Executive Editor. I won't copy and paste the entire article/editorial by Sturgess, but here's a synopsis---
It turns out Sturgess is a 928 owner. He starts out his piece commenting that his cars (a 928 and a Jensen Interceptor II) are hard to keep cool---he lives in SoCal.
In his end of the TRUCKING BUSINESS, he has happened upon a coolant product that Ferrari used/uses in Formula 1 racing with very good success. (Yeah, I know trucking doesn't have much to do with Formula 1, but he's a trucking mag editor......go figure.) The product is Evans Cooling NPG+ coolant. It is a non-water based coolant that doesn't have a boiling point under 370 degrees, instead of the normal 220-230 range for ethylene glycol/water based coolants.
He goes on to point out the many advantages of raising the boiling point of coolant in various engines, the 928 engine included.
As Sturgess also reminds those of us who also own and operate Porsche 928's, if you can prevent a water pump change or coolant over heating/leakage (or aluminum vs coolant corrosion---my addition), it's a very good thing. You can run hotter thermostats, increasing mpg's/power and lowering emissions. Those of you who are running blown/stroked/modified 928's should see many benefits as well.....you could even run a non-pressurized radiator cap, giving relief to the hoses, H2O pump seals and engine gaskets as well.
It's not an inexpensive product (a reported $40 per gallon), but if the data and performance claims are correct, this could be a life saver for many engines, not just our 928's. Mmmm....4 gallons ($160) is nothing compared to the cost of blown head gaskets and leaky water pumps, if you get my drift. (Of course, my big rig holds 12 gallons, so you can see there is significant cost to me in that regard.....but---- this week I am doing a headgasket job on my 600 HP Cummins, and the cost of that will be near $4000. Wow, I wish I had known about this product soooner....!!!!)
So there you are Ryan, good friend of mine.......a product heads-up from (another) trucking industry guy that might save the life of countless 928 engines that are forever needing an advantage to keeping coooool.
Cheers----

I must ask...why is it common for "tuners" looking for more HP to instantly install a COOLER thermostat...yes the stock cars run hotter for emmissions reasons..but a cooler engine will always make more power than a hotter one....????

the turbo cars are running 200 degree thermostats to get the heat up in the engine (turbos) prior to running.....
my long time partner's 540 BBC (in a quick 32 Chevy II) also runs a 200 degree 'stat....that, combined with a NASCAR style radiator never lets the engine get over 205 while making a pass in the swamps of south Florida (90+ degrees every race weekend).
I can't say about the "tuner"crowd. I don't follow anything that has less than 8 cylinders unless it's diesel powered (?)
The Evans stuff will go into everything I have.....soon.

Russ, is this another drive by post, and then you will not post again for another 6 months?

article was given to me by a friend and I thought it was good info for the community as Sturgess has a 928.......

worse than rough when you're being pulled in several different directions across the country as once.
finally put an end to the stress---went to House of Blues (as if I needed more of the blues) and then the drags for two days----wish it had been for an entire week.
oh well, off to Florida for some surfin'.........

ATTN MOD: Can you please change the subject line to something more in tune with the topic of the thread, and remove my name from the subject line.
To Russ,
Uh glad you decided to post Russ, but WTF this has to do with me, and why my name is in the subject line is beyond me. Please remove it immediately.
If your going to put my name in your subject line, I would appreciate it if you spelled it CORRECTLY! Please remove my name immediately.
To that end, I have asked you numerous times NOT TO MENTION ME, and that includes putting my name (or what you thought was my name) in the subject line of the thread. Please remove my name immediately.
PLEASE REMOVE MY NAME FROM THE TITLE OF THIS THREAD AS IT HAS NOTHING TO DO WITH ME!
and yes Ferrari has been running their F1 engines ABOVE 300deg (I believe operating temp is in the 320 range) for quite awhile, i first read of this in about 02-03. Glad your keeping up with the times.
But again, please remove my name from your thread and PLEASE, do not reference me in any of your posts Russ. I thought we had gone over this enough.
Thank you

Time will be the judge of the overall merit, but a little digging and I found a table of specific heat capacity, how much energy it takes to raise the temp one degree, a basic factor in the equation of how much heat the stuff can transfer when used in a heat exchanger situation like cars and radiators.
Specific Heat Water 50/50 NPG NPG+
80° C (176° F) Btu/lb/°F 1.00 0.81 0.68 0.64
100° C (212° F) Btu/lb/°F 1.01 0.82 0.71 0.66
Looks kind of questionable trying to use this stuff with a factory cooling system.
Specific Heat Water 50/50 NPG NPG+

water "cools" much better then does coolant. It dissipates heat or energy faster then does water with additives. In CA i prefer to stick closer to a 75% water25% coolant mix, with the coolant used basically to raise the boiling point and to act as a lubricant. But straight water will cool faster then does straight coolant.

Whuuuuuut? It has been my understanding engines are more efficent and therfore more powerful when they run hotter than colder. Not too hot though. If your theory were right no one would install a thermostat. Perhaps you are confusing intake air temps. Now that is where cooler is always better.
