My Corrado (VR6) normally runs 215 or so around town during the summer 
months. 230 - 240 is common at 80 mph. Hard driving had generated 270. 
A friend who races has seen 318!! Not a whimper from the motor. Installed 
an additional oil/air cooler to supplement the factory oil/water, just to 
be safe.
