I installed an M112 supercharger. In the processes of tuning the engine. A strange noise happens when boosting. I am afraid to push it because of the noise.
noise sounds like- a sheet metal rattling sizzling buzz
noise happens
noise happens- when engine is under load only pushing boost to 3 psi above 4000 rpm.
noise happens- when engine is under heaver load pushing 6 psi at 3000 rpm.
noise happens- when engine is under heaver load (more than 3/4 throttle) pushing 10 psi boost 2500 rpm.
The heaver the load the sooner the sound.
The sound comes from somewhere in this region. between the back of the engine to the front portion of the transmission. Sound is coming from under the dash in the center of the car..
Any thoughts on what it could be?
