He's worked on my Z, and look at my 1/4 mile time in my sig.

Oil cooler barely helps in situations like the drag strip because of limited airflow... your mostly putsing around the return lane and pits heat soaking up everything, and the only time you have airflow you are at full throttle anyway... so let the car cool off to 180 oil temp before getting it ready to line up, so its hopefully still under 200 by the time you start the run.
And if your 60' isnt in the 1.8 or better, you need to work on your launch. I was able to get 1.88 and 1.89 on bald stock sport wheels/tires with a stock car, so you should be able to do better than that if you have some decent tires.

160F to 180F seems to be the sweet spot for my car for good runs, anything more than that and your ET's will suffer. There is definitely a noticeable power drop on the butt dyno above 200F. I usually wait a minimum 30 minutes between runs. Ideally 45 to 60 mins between runs for best results.

The tune should make a big difference with your mods. You should come up to PBIR/Moroso once your Z is tuned.
