Just to clarify: The intercooler doesn't cool the turbo itself, it cools the air that was heated by the turbo. (A turbo compresses the air, and if air gets compressed, it heats up)Basically, if you have been revving the nuts off the car and the turbo gets hot and you don't let the turbo cool down (let the engine idle for a bit so the heat exchange/intercooler can do it's job and cool it down, then the oil that is in the turbo boils and then seals go,bearings sieze etc.
????caz1562 said:Intercoolers do not cool the air heated by the turbo, thats what the exhaust is for :wink:. Air is sucked in via filter, this assists in the drop in temp of the air before it meets the fuel in the chamber charging the air thus giving an increase in power. Once the exhaust gases enter the manifold, they're passed across the exhaust vanes in the split turbo casing to keep the turbo spinning during gear change, this helps keep the turbo charging with air on the inlet side too.
So if I leave my key in position I for about 1 minute after a hard drive it should be fine?
Or should it be in position II and should the engine be running ?
