Not sure I'd do the bypass loop on a supercharger....intake air temp gets high pretty quick. I used that trick for controlling Eatons during automatic trans upshift and approaching redline (production based cars) to prevent breaking the engine (when the ECM runs past the window for KNK control). Unfortunately, if your driver spends much time holding high RPM (while looping the airflow), the knock sensors break anyway....shortly before the pistons.
I still chuckle about the day Montoya pulled a pace car into the pits (he had "celebrity rides duty" that day), saying "Jeem, Jeem, I have NOOOO POWER until six-thousand, two-hundred RPM....then BEEG POWER and CHECK ENGINE light on!" Not thinking well, in the heat of the moment, I parallel jumpered the remaining "live" Knock Sensor into both banks of the ECM, then we rotated him back into that car.
Pistons were gone in about 3 laps.
He was a real gentleman and didn't blame me....but it was my goof.
Lots of detonation when that intake air gets preheated over and over.
