I could see switching positions with the car at idle, but if he were to open them up at a certain RPM I'm not sure if that sudden change would have any negative impacts.

electric cutouts that open up at a certain rpm to increase horsepower for the top end but are closed at low rpms for torque. but then i forgot how they dont have pimp *** turbos like we do

i think maybe the only concern would be at a road course or auto-x event when they would be open for long periods of time, but even then im not too worried since my car will be moving the whole time.
