No I have no temperature gauge

 

Interesting on the speed front.

There was a LOT of discussion on here a while back that the aerodynamic characteristics of the MY00 and prior Imprezas are such that they do not flow at all well from a cooling point of view at high speed.

IIRC there was talk of positive underbonnet pressure, therefore little or no air passing through intercooler and correspondingly high intake temps. Also high oil and eg temps for reasons described above and inadequate cooling.

Just some additional thoughts...

But, at the boost required to hold this (0 to 5, it seems), how much does the turbo heat the charge? I'd have thought 'not a lot' would be the answer (I'll try to look into this, but don't have an inlet temperature gauge nor do I have the wads of equations here needed to calculate it!). If the inlet temperature is barely raised above ambient, then the intercooler doesn't have a job to do. Unless of course it has changed into an interheater, in which case it really wouldn't be helping matters...
Haven't FMIC equipped cars gone as well, though? Or was that 'just' big-ends?
