Question or two? When he backs up and moves over his spotter sprays something in the scoop. I have never seen that once the motor is running. What was he spraying?
One more? After he staged his spotter went to the back of the truck and flipped a switch. What was that for?

On a blown alcohol motor, a lubricant is sometimes sprayed on the butterfly's/linkage entering the scoop to keep things from binding up. Alcohol dries things up something terrible, the lube (probably a teflon based spray) keeps things moving.
The switch on the back on is to turn on a data recorder. It will monitor engine RPM, driveshaft RPM, wheel speed, EGT, water temp, fuel PSI, etc.
