Intercooler Coolant

[jharrison]

What is called out in the owners manual for the charge air cooler? Is is best to run the same as the cooling system or does plain water with something like "water wetter" work better?


If anyone has the original 91 Syclone owners manual, I would pay for a copy. Either digital or color photo.

As far as cooling, straight water with wetter has the best cooling properties. Followerd by straight water, then 50/50 with WWetter and then straight AF in that order from best to worst.
However, its not good to run straight water in your cooling system for 2 main reasons. One is that there is no protection fom rusting out the iron block. Two, there is no freeze protection in cold weather.
The intercooler system probbaly is all aluminum, so the first issue should be void.
This info was basically directed at the knowledge of the radiator and engine cooling. IDK specifics on the boost intercoolers tho. I imagine they are parallel.
Hope this helps.

arnt those intercoolers just air to air, I didnt think that they were a air to water design. If they are air to air i would just add a meth injection kit or a nitrous spray bar for the intercooler. If they are air to water then i would say some water with wetter or maybe just ice water.

My understanding of the subject is pretty much what Mike just said. The systems usually have no iron in them just aluminum/plastic/rubber/Stainless

So rust is not a concern Aluminum can corrode and you generally need something to protect against freezing also the Water Wetter and the anti freeze raise the boiling point. Another thing the whole system is usually 1/2-3/4 of a gallon. I've seen some make a larger/custom coolant tanks the larger volume helps reduce heat soak you will allways get some though. On some bigger vehicle like Silvy's and such they will even use a Schirocco radiator for the AWC wish we had the room.

You basically have four components 1) Core between S/C and motor 2) Resivior (tank) 3) Pump 4) AWC basically a radiator.

Often times just a big transmission cooler is used for the AWC. The pump is usually just a small impeller pump. The core is usually the exspensive part it's the more technical part it's gotta transfer heat and it's gotta have minimal restriction for the water passage and also the air flow for the S/C.

Sorry I don't think you asked any of the "qustions" I just answered I just started rambling. my bad.

See this site for lots of info they have a great F.I. section.

Thanks guys, I think I will run straight water with some "wetter" then add AF when winter approaches. Aside from an overflow line running from the intercooler to the radiator overflow tank the two systems are seperate. So for the actual cooling system I will stick with the usual AF / water mix probably with some wetter just for a little additional help.
