urQ: Cooling questions ....
I was talking to a fellow urQ owner over the weekend ... one who has a
lot more discretionary income than I do ...
He has an RS2 turbo installed in his car ... but it turns out that I can
keep up with him fairly well with a relatively unmodified QTC. He says
that he has been told that the limiting factor in his set up is the stock
intercooler. I told him that AFAIK most urQ owners used the OEM IC (how's
that for acronyms!). He was thinking about getting an IC for an S4 and
trying to work it into his car. He said he knew of someone that had moved
the oil cooler to be in front of the Rad & A/C condenser so that they could
fit a larger IC ... sounds weird to me. Anyone willing to divulge their
[as an aside, he was also told that the Euro fuel distributor was necessary
to be able to crank the boost up much without worrying about lean-out prob-
lems. Does anyone know about any differences in the FDs? Is it possible
to swap in a FD from a newer 5k/0.2k motor?]
On a similar vein he was wondering about eliminating the aux radiator that
the urQ has in front of the engine ... I told him that he would probably
need to increase the size of the standard radiator. Any tricks that anyone
has used here?
Last, but by no means least, he had heard that someone had added a ventila-
tion port to allow heat out of the left side of the engine compartment. He
was not aware of exactly what had been done, but it sounded like this person
has added some cut outs in the firewall and hood in front of the windshield.
I told him that it seemed to me this would be a high pressure area ... so I
wouldn't think much air would be coming *out*. I told him that the better
candidate would be to add any exhaust vents behind the wheel wells ... Has
anyone heard of someone who did such a mod to a QTC?
It sure seems to me that the person that is providing advice is mainly try-
ing to get this poor urQ owner to pay big bucks for stuff that is relatively
untested ... I keep telling him that he should get on the q-list, but he
says that he doesn't even have a computer. My thinking is that he would
recoup his investment in a cheap computer very quickly by joining the list!
TIA for any info that you think might help!
