Not that it's worth comparing, but....
A friend has installed the THS Type 3 to a 1999 Audi S3 remapped to 17psi boost.
Ambient temps were around 10 degrees c. IAT's did not go over 26 degrees c. on 4 consecutive 4th gear runs.
Although this cooler is much smaller than the type your fitting it showed very good cooling capabilities.
The same cooler will be installed on a LCR shortly.
