OK first regarding the sound issue. Childs has provided another sound board. I have put it on and will test. Fingers crossed.
Now for the Supercharger:
WIth the guys at childs on the phone, I did a sensor test and they all open and close, tested by using a screwdriver as suggested by Childs and Angelo. Then did a speed test and got numbers like 46, 71. The most I got was 226 but I might have thrown the ball up there very quickly myself. The ball only does one loop and comes back down the entrance ramp.
It was suggested that Nino's services might be required again by the boys at Childs.
Cheers
