looking for another oil cooler

The interesting thing I discovered was that on track straight-line speed was roughly the same after 20 mins as it was in the beginning of the session, however climbing hills under load there was a noticeable loss of power especially in the lower RPM band. Would be interested to see why the low RPM is effected more.
