Here's my problem, i have big swing in et when my engine has cooled (still up to temp but my water pump and electric fans are not on) when it has cooled enough to turn of the pump and fan.(run off of thermo switches) My car will run a full tenth faster. 8.27(1/8 mile) Hot lap it and it runs a 8.35.
With my old motor, i have a full throttle kill switch that killed the alt charge while i was going down the track. i believe it helped, but.............
Those that have installed a hood scoop, do you think it's the hot air being ingested from under the hood or do you think the alt is robbing that much power when it's trying to keep up with two electric fans running???
