I have a standalone installation in my 1.8T engine, and now I keep an eye on things like temps, etc.
I believe there is quite an issue with heatsoak when you stop the car after fully warmed up.
Even after driving, and the IC and cold side pipe are really cold, the intake will be hot, and even too hot to touch.

Question:
Is there a way to take the temperatures down?
I think I might have seen something about a intake manifold gasket that would help the temperature not getting that hot, but not sure that is good or what.

Cheers!

I'm in Portugal, so summer can be quite hot. Winter a bit cold, but no snow or anything.
I might consider this. 034 is the cheapest place to get it?

How much would that run me?
Are there any values on difference in temperatures?

mine are ÂŁ59 inc gaskets bolts etc

conducted heat is significantly lower but relative to how hot the engine is.. Recovery time is much quicker also, as cool inlet air cools just inlet mani not head as well

Bill, is that with posting to PT?

I think I might get this on the next Spring to do list.
Maybe now, for the winter, is not that huge of an issue.
Thanks for the info guys.

I could be wrong, but I don't think you can just install a secondary coolant pump on any car. They came factory on VR6 and auto 1.8's. You'll need the pump, the lines, the split from the radiator hose, etc. Not to mention they die easily and aren't cheap for a tiny motor than runs for a couple minutes after you shut the car off. I personally think a phenolic gasket, better intercooler, and/or water/methanol injection is a much better investment. The gasket is the cheapest of them all, and should help. But WMI will probably show the biggest change in temperature. I know you say you're running a stand-alone; is it controlling the fans? Does it allow them to stay on after the car's been shutoff? If not, look into a good controller with that option, and maybe a couple higher cfm fans for the radiator. Are you trying to lower the coolant temperature, or just the intake temp?

I run water meth and a manifold spacer, my intake is anywhere from very cold (below ambient) to just warm depending on how I drive it. I attribute almost all of this to the water meth, as when I didn't have it on the manifold would be too hot to touch.

hmmmm... mine usually only gets hot after i park the car or when i've been in a lot of stop and go traffic. even then, it's nothing out of the ordinary. Look into one of those fancy spacers first. if that doesn't do it for you maybe w/m

My main concern is drag racing. Whenever I go there, the IAT will be like 45C or more when idling and waiting, and when I push it, it will raise up to 60C.
Not good...

I had the same concerns when Hill Climbing with my Camaro. Kind of a Mega Dragrace ( 2 minutes long )

We found a 1 -2 gallon water sprayer to be very effective. Just spray the manifold down before you run. And keep the hood up until the last second.

Edit: You could also spray down the intercooler just before you run...but a CO2 sprayer works much better for that.
