80tq drag racing- Intercooler reevaluation [long]

[Tom]

hmm, I think you should consider the ambient airflow through the core some
more. Audis tend to run higher underhood temps than I've noticed with other
cars. I have a feeling this is due to poor venting of the engine
comparment - although the side mounted radiator isn't helping. Even a large
front mount will quickly be rendered useless if there is no place for air to
escape from the rear. The IC becomes a large heat sink rather than heat
exchanger at that point. Your spearco core looks plenty big - unfortunately
there is a timing cover directly behind it :-(

Depending on your asthetic reservations, some carefully located holes in the
hood might help.

displacement to get the same amount of power (or so), I am running 18psi in
a 2.2, and attempting to replace displacement with boost.  Also, the S4 has
a much more advanced management, so it can cut boost when temps get high and
still get down the track, where my boost is manual, all the way no matter
what  =)
