Hey Jag are you still running distilled/water wetter? I've been looking into coolants as well, currently I have a partial mixture of the leftover OEM and Liquid Performance
I'm in Texas as well and not concerned with the lower temperatures or ethylene glycol. I'd prefer to run a water based coolant that's track legal which is why I'm leaning towards VP Frosty to replace LP. I've looked at Silkolene Pro CCA Ultra which is a corrosion inhibitor added to distilled water or it can be an additive to Silkolene Cool, their form of antifreeze. Researching friction modifiers doesn't show much as they're proprietary and we can only refer to the MSDS or technical spec sheet for any kind of insight as to what's actually in the coolant. We wont consider Evans waterless or ENI, unless someone has something specific to say about Evans having a benefit, which I could not find. I know that dude with the printed inconel exhaust runs it but idk it just seems off and system dependent, along with prep fluid - scheduled maintenance - coloring from heat cycles that just seems too much.
Relative density or specific gravity are the same definition, fluid density at a given temperature, with pure water being 1.
The fluid density of...
VP Frosty is 1.03
Silkolene Cool, which we don't want because of ethylene glycol but we'll use as a reference to VP frosty is 1.04
Since we all want the coldest running bike/best corrosion inhibitors with the highest viscosity, which is why pure water is usually used, we still need a corrosion inhibitor, like Water Wetter or Silkolene Pro CCA Ultra.
WaterWetter specific gravity is 1.08 per Redline
Silkolene Pro CCA Ultra is 1.11
So, we have a .03* difference in fluid densities at given temp . Those .08 and .11 weights are the additives to water(1), in theory.
* There's another MSDS with WW density being 1, but that's impossible because Water is 1.
And Silkolene Pro CCA Ultra can be added into Silkolene Pro Coolant, which remember has a similar density to VP, with VP technically being lighter at 1.03 compared to 1.04.
The pH of VP frosty and Pro CCA Ultra are also the same at 9-10, Silkolene coolant is 7, so we're still in a good range of pH compatibility and fluid densities.
So considering all this:
- Water Wetter and distilled will put your fluid system at 1.08
- VP Frosty straight in is at 1.04
- I feel like we can substitute Silkolene coolant with VP, considering the weights are almost identical
- I'm thinking about using VP Frosty and diluting it with Pro CCA Ultra at 5%, to arrive at a fluid density with same pH
- 3% of 1.11 is .03 and 5% of 1.11 is .05, added to 1.03, brings the new mixture to the same density of WaterWetter/distilled at 1.08 or 1.06 is you dilute at 3%
Who knows what's in WW? .08 of friction/surface tension modifiers? The product does work, but we all want a better performing system considering we're usually WOT. You could use Ultra Pro CCA and distilled but that would be 1.11, too heavy? Again the VP Frosty with Ultra Pro CCA is lighter at 1.08, although we have more friction/surface tension modifiers in it relative to
only Water Wetter/water or
only VP Frosty.
In the custom blend, VP Frosty excess of .03 (water is 1) and 5% of Pro CCA at .05 is the .08 of "product" we use along with included water to cool the engines. You could continue to use WaterWetter, but there may be additional friction/tension modifiers that benefit the cooling system and inhibit corrosion with VP/Pro CCA blend. I will call it Dragons Blood
