EVANS NPG™ COOLING is a new technology, a system initially developed for cooling race engines to reliably increase power. It does that and much more. It's a racing-tested engine cooling breakthrough! The technology is centered around a revolutionary new coolant, non-aqueous propylene glycol (NPG). In addition to our own race teams and testing programs, NPG technology has been proven in many different racing vehicles, street machines, trucks and motorcycles. Evans NPG has been run in 2000 HP drag cars, cross country vintage racers big block modified cars. EVANS NPG has also been proven invaluable in all makes of Motorcycles; Exotic high horsepower racing bikes to 1500cc, 6 cylinder touring bikes. As NPG™ was initially developed on the track in our high performance cars - we know and have addressed the cooling issues faced by the racer in the fiercely competitive world of cutting edge technology driven - motorsports.

NPGT Coolant Ends Coolant Maintenance & Expense - Run
Longer - Run Safer - Never Overheat ! |
Engines have the capacity of operating at much higher efficiencies which lead to higher power production. The limiting factor has always been the conditions imposed by water-based coolants, including low boiling point and excessive vapor generation. These conditions cause localized coolant boiling, vapor blanketing at hot spots and the resultant destructive detonation and pre-ignition. In some applications, coolant alone will improve fuel economy and reduce emissions; in others simple mechanical modifications may be required.
When vapor blankets the surface, water-based coolants lose their ability to absorb heat from the hot spots in the combustion chambers, leading to high metal temperature spikes well above critical levels. The result is loss of power from detonation or component structural failure from pre-ignition in the form of piston damage, head gasket failure, and/or warped or cracked heads.
Water-based coolant is operated near its boiling point. Cylinder liner cavitation erosion is caused by vibration-induced high frequency pressure changes at the metal-coolant interface. Coolant, near its boiling point, makes vapor bubbles that abruptly collapse against the metal surface, causing erosion of the metal. EVANS NPG Coolant contains no water and is not operated near its boiling point.
The boiling point of EVANS (non-aqueous propylene glycol) NPG Coolant is 370 degrees F in a non- or low-pressurized system. The coolant is normally controlled at conventional temperatures but functions perfectly well at higher temperatures, even considerably higher temperatures. Detonation/pre-ignition control and previously forbidden combustion chamber pressures and temperatures are no longer the danger they were to thermal engine efficiency and durability.

NPGT COOLANT
USES NO WATER, NO PRESSURE!
Evans
NPG Coolant is 100% inhibited Propylene Glycol. It can maintain substantially
vapor free, liquid - to - metal contact at all coolant temperature and engine
loads. By bathing the entire combustion chamber with coolant 100% of the time,
metal temperatures are controlled to such an extent that critical levels of
detonation and pre-ignition are never reached. Because NPG's naturally high
370 degree F boiling point, the need for adding high pressure to the cooling
system is eliminated. Without pressure (or low pressure, i.e. 2 to 5 psi) in
the system, gasket seals, hose connections, and even the radiator core, operate
safer and longer. For a brief overview of the properties, please read our NPG
properties
tables found in our technical
info page.
This is a simple outline of a few general cooling system benefits / engine enhancements that our systems can provide. For a more detailed and specific outline of our system along with the increases in cooling system / engine performance you can expect to gain, please read the data in our technical info pages. For more benefits and descriptions see our benefits pages.
For competition engines that are pushed to excess - into extremes, Evans has a wide range of NPG optimized components from high flow coolant pumps to NPG enhanced radiators. For maximum engine performance and protection under these excessive conditions, no other existing cooling system will operate with greater efficiency or provide greater engine protection! Most of our NPG optimized components can be viewed in our catalog page.
For an in-depth discussion of the problems with current cooling systems and how Evans NPG solves these issues, please read our narrative in the NPG benefits page.
