Cracks in the exhaust will do that. Also brackets that are holding exhaust and shields that have cracked will do that.
I've heard that noise before for sure.
Will it do it just reving in park or do you have to be in gear driving?

Just came back from Dyno the roller was very noisy but it gave us general idea where the sound coming from seems like it's coming from passenger side area around the air filter ,guys over there told me to change the rubber acordion that's holding the maf housing and to check the TB blade and if it doesn't fix it to come back to them

Wow I found the whistle and many many other small leaks came from a lot o small places from middle part of blower see the pic also from a broken O ring in evac canister front of blower also one of the fuel rale bolts was leaking air and the boost gauge fitting on the back of blower was leaking. I built boost leak tool took me half hour to make it very easy to do and I think everyone with a supercharger should do this test.. Looks like I will pull the blower of take it apart add new rtv and new gaskets..
Thanks for the help guys good luck out there.

Epoxy is for around shader valve it's liquid and will go into small cracks a
The super glue is for the rubber kn filter this to make it slightly smaller
