Curious Squeak

[nazrin]

I had heard different explanations of this squeak noise when you become unhooked with a loaded engine, what is this noise?

what I have heard was; the noise is the friction washers on the SC gear, and also have heard that a N/A 4tec does the same noise and it is pointed at the impeller spinning up with air and or air bubbles in the tunnel.

You can't hear the supercharger slipping, the noise you hear is from the jet pump.

Naz, when the engine is cold, run it for 30 seconds then turn it off. Wait 30 seconds and check oil level, it should be in the center of the bump on the dip stick, not filled to the top. If its over filled it will also keep your rpms lower.

Can you explain why the pump makes that noise.

Re: Curious Squeak

When the pump re-loads it has air bubbles in it and the air bubbles create the sqeek or high pitch humming noise, Its friction and gets real hot.
