The cold side temperatures can exceed 200 C if you are getting up in boost -
that's why a larger intercooler can often give a significant performance
increase. That is probably hot enough to bake that lovely rubber smell out
of your hoses, particularly if they are new. I vaguely recall a post about a
lister melting the plastic crossover pipe on one of the later model UrS cars
as a result of boosting a K24 into a lower efficiency (read high heat

I changed the temp switch on the radiator, and the MFTS during my belt
change, and I now have a perfect working fan system.
(On the s-cars the fan resistor pack is located just behind and over the
IC, and it's sealed, so I just checked it with a multimeter..)
I can even see what temperature the car has for more than 5 mins at a
The after-run also works, just had to get it hot enough.. ;o)
Btw, why does it smell like burnt rubber from a fresh RS2 conversion?
(Not the tyres..) there's no rubber material anywhere close to any hot
parts, so I'm a bit confused here!
How hot is the air from the turbo supposed to be? (had to press the
turbo to x-over tube a bit higher on the new turbo, so it might be a bit
more in contact with the cold side housing.. But I didn't think it would
get that hot there?
'92 S4 (smells like fun..)
