Back in 1992 I had an 86 Corvette that I ran at New England Dragway.
There was a plug on the A.C. line that I would unplug to keep the fan running as soon as the car was started.
This would help cool down the car when it was running in the staging lane. I would plug it back in for daily driving.
This plug might be worth looking into.
Keep us posted on your progress.
