Would a hood scoop help my problem?

If you have a scoop you need to seal it to draw outside air. IMO an open air cleaner pulling hot engine compartment air is the worst setup you can run.
I run a 160 thermostat and temp bulb switch to control the elect fan solenoid in auto mode/street driving. I also have a maual overide switch to turn the fan on.
I try to stage the car at the same temp and have the fan manually on. After burnout I turn the manual overide off and let the temp bulb switch takeover the fan. At 100+ mph the fans should not even turn on.
I turn the manual switch back on after the run and repeat.
My car runs the same ET or quicker when I hotlap. I have a good cooling system and run a tight converter for a street/strip car.
