Took my intercooler off to clean it and the Ali fins just broke off when I touched them ,seems they have got quite brittle after 14 years!!!
So two questions
1.if I take the fins out will it does it dramatically affect the efficiency, as anyway the intercooler was packed with dirt between fins and the Bars?
2.while taking it all apart I noticed a screw driver size hole in my cold side lower intercooler hard pipe, no bracket attached in that place ,so I am thinking boost leak? How much effect would this have?

I'll try to attach a picture



Cheers Marky

Any boost leak will have an effect, bigger the leak greater the loss. Hole in hardpipe is an easy fix as can easily be ally welded

The turbo will spin faster to try and compensate the leak and build the same pressure. This in time could reduce turbo life significantly.

I noticed something similar on my 8MR caught it before it went all the way through though. It was rubbing on one of the sensor bracket things attached by the fan
