My question is specifically about Purple Ice. Anyone have any comments on it?

Used it in my car, had to get the antifreeze/water ratio down for the best performance but it helped me keep the van cool while I was towing a trailer. Have not used it in my bike yet but was thinking about it. Some of these additives caution against using in a low pressure system (under 10 lbs) not sure what an 84 aspncae runs at (guessing somewhere between 12 and 14 lbs).

IO think 14psi is about right. Purple Ice must be better known in the USA as I haven't heard of it this side of the water.

Most water cooled Honda's run about a 1.1 bar cap (about 15 PSI). These coolant additived supposedly reduce the surface tension of water and allow it to interface better with other materials (like aluminum) to better transfer the heat away. There is data out there that says it works - I've seen "water wetter" used at some sports car track days. Why do you need to make this marginal improvement - maybe something else is amiss? Bob
