Hi,
Anyone had a Fog horn or trumpet loud noise from their supercharger when it engages ? It will only disengage when you drop the revs back/down?
No air leaks, no loss of power, all belts and pulleys ok, new air filter. No black smoke.

thanks for any help
 
It means the air is coming out between the compressor and airbox/silencer/turbo. They are damn loud when running unsilenced!
 
It's been a long tie since I was under the "hood" on one of those, but if memory serves, there is a silencer between the compressor and air box. The sound you describe is the sound the compressor makes if the engines are run without the air box on, so if this is a new noise that has appeared since the air box was fitted, I suggest to take a closer look around there again.
Good luck.

Thank you it was there before the air box was changed hence why it’s strange
