[Es2] things that tend to break on es2's at the track

I think the 034EFI style radiator holds enough extra coolant that temps
shouldn't be affected by removal of the aux. radiator. But if you
remove the aux. radiator, I think you need to plug off the hoses, not
just connect them together. I've heard that connecting them allows some
coolant to bypass the radiator. That might raise engine temps.
Either way, the thermostat should regulate the engine temp. If the
engine is running hotter than usual, you may have a sticking thermostat,
or the wrong coolant mix, or you don't have the radiator shrouds in
correctly (they make the air go through, not around, the radiator).
I may include the 200q aux. radiator when I do my coupe; it's larger
than the stock coupe aux radiator, and might ?? fit down low in front,
instead of behind the grill.

That's interesting Dave. I have an S2 where I removed the aux cooler and
I would agree with you. I think it made a small difference and I am
running slightly hotter than before. In retrospect, I think Audi put in
the aux rad for a reason.
I have heard it argued that a larger IC, by lowering the charge temp,
will lower engine temps. The lower intake temps propogate through the
Makes sense to me.
I have not done it yet, but my idea was to remove the aux rad to make
room for a larger IC. I figured the effect of the larger IC would cancel
the effect of the aux rad removal. So far I have only gotten half way.
