Burning Oil?

I also slightly overfilled my 200TQ when I took it to the track since it was the conventional wisdom of others who were tracking their UrS4's.  I never had any problem other than the smoking and that cleared up immediately after removing a the extra half a quart of oil.

It is amazing how the 200TQ responds on R compound tires but it was also amazing how fast the car could eat the tires up due to its heavy weight.

I actually try to overfill slightly before a track event due to the 
cornering forces but replace the oil right after and fill just to the fill 
line as it is cheap insurance on a fully built/balanced motor. Do you see 
any adverse effects from overfilling aside from some slight smoking? I've 
done everything I can, UrS4 windage tray for left hand corners and custom 
baffle for right hand corners to prevent oil starvation/crankcase breather 
leakage) and generally don't have a problem w/ oil pressure even w/ R 
compound tires. But Portland Raceway doesn't have any really long high G
