a few ideas you may or may not have already tried...

1. Reduce weight, I think its about 1/4 second et reduction per 100# reduced. Have 1/8 tank or less of fuel, remove back seat if thats a possibility, remove spare tire and anything else from your trunk.

2. Improve your launch. If you are spinning, that is a et killer

3. Make sure you are getting full throttle and have good plugs and tune up

4. Optimize ignition timing. Try a few degrees each way to find the best. If you hear 'ping' during a run - its too far - get out of the throttle.

5. After driving to the track, let your engine cool off. The oil will keep the heat longer. The best is hot oil and a cool engine.

6. Let it breath. A clean air cleaner and the least restrictive exhaut as possible.
