This is news to me. My only agument to the documented success is that =
it seems contrary to principals of engine cooling. The conventional =
water/antifreeze mix boils in the cylinder jacket and boiling is the =
most efficient means of heat transfer which means it will keep your =
engine the coolest. They admit that with NPG+ the engine runs hotter, =
but claim that is a good thing for better efficiency. It is true that =
the hotter the engine the more thermodynamically efficient it will run, =
but it won't run long if the temperature is too high. Us with air =
cooled engines don't seem to be looking for ways to increase our engine =
temps. I suggest you record your CHT/EGT temps wtih the distilled water =
and compare with NPG+. If you're comfortable with the higher temps =
using NPG+, then I guess it will be ok. Eliminating boil-over is a =
detriment rather than an asset IMO. With a conventional coolant if you =
lose coolant circulation, it boils over. However as long as it is =
boiling over, you still have cooling and time to prepare to shutdown =
before your engine overheats. With the NPG+, I think overheating would =
happen immediately upon loss of coolant circulation.

Greetings, =20
I wanted to get the information on a product I plan on using to all =
the liquid cooled engine experimentors. Specifically the NPG+ is of =
interest. I know that it seems to work well in race applications and =
should add the little extra benefit that our hard run engines may need.=20
I plan on firing up my Chevy V-6 in about 4-6 weeks and will use =
distilled water to ensure I have no leaks. Then I will flush the system =
and put in the NPG+.=20

Let me know what you think, and I hope it helps. =20
