This has been used with great success throughout the drift scene, so we thought we'd stock a load of it and offer it to our customers: It aids cooling, but more importantly doesn't boil until over 180 degrees C, so you can run the engine to higher temperatures without the risk of damage, which as a side effect can improve efficiency and power. You need to use the special prep fluid once, and then the Evans PowerCool lasts a lifetime. Get your Evans Waterless Engine Coolants from Driftworks.com
I cant find any info on expansion rates over a given temperature rise, you guys know where I can find anything like that?
Its all just sales shit. Im sure its all good and that, but it just looks marketed at Ripspeed customers..
From Evans: Evans will expand at around 7% by volume so there isn’t a significant difference. The much lower pressure will come in to play because there is no steam generation to add to it, therefore the only pressure present when using Evans is from expansion.
I'm hugely skeptical about that stuff. Not jus as it's flammable as fook (not allowed at some tracks IIRC), but knowing what it's made of, I'm not convinced of the claims or that there's not more issues than Evans like to say. This is 'interesting' and pretty much backs up what I've always been sus about. No-Rosion Products Technical Questions and Answers
Didn't Japspeed use it in there cars last year? If they did, did they have any cooling issues like previous years.
So pressure expansion is pretty much the same as water providing there isnt pressure loss or temp doesn't rise past 120-130.. uh.
SUMMARY OF FINDINGS Conversion costs of $259 if you do it yourself, or over $400 if you pay a shop to do it. 97%+ removal of all previous coolant is mandatory in order to prevent corrosion. Inhibitor deposition occurs on aluminum surfaces, which could cause issues in some radiators. Engines run 115-140oF hotter (at the cylinder heads) with Evans products. Stabilized coolant temps are increased by 31-48oF, versus straight water with No-Rosion. Reprogramming ECU fan temp settings is mandatory to prevent the fan from running continuously. Specific heat capacity of Evans waterless products ranges from 0.64 to 0.68, or about half that of water. Engine octane requirement is increased by 5-7 numbers. Computerized ignition must retard engine timing by 8-10o to prevent trace knock. Engine horsepower is reduced by 4-5%. Accelerated recession of non-hardened valve seats in older engines is possible, due to brinelling. Viscosity is 3-4 times higher than what OEM water pumps are rated to accommodate. Coolant flow rate through radiator tubes is reduced by 20-25% due to the higher viscosity. Race tracks prohibit Evans products because they are flammable and slippery when spilled. Yea seems amazing stuff
My question on this is if you have to remove the rad or drain the coolant system at any time do you have to use new fluid or save what comes out and put it back in?
