I have just been offered an intercooler off a legacy (water to air). have any of you intercooled an ea81t, and if so, how much effect did it have on performance?

I would normally just try it and see, but installing a water to air intercooler will probably mean sacrificing the air conditioning, and repositioning the spare wheel, so i don;t want to go ahead if it will make little difference with stock boost. comments?

I do not know if anyone has done this with and EA81t, but ICs are often put on the EA82t. Some people have posted after-turbine temperatures from stock boost of 200-250 deg F (95-105 deg C ?). Dropping the temp down to near ambient is worth doing alot of work.

It has been done to an EA81T powered car. It was done by Boosted84wagon. Send him a PM and try to get him to tell you about it or have him post here. I'm interested in his results as well!
