I hear the noise, but am unsure on what it is. Sounds like a turbo almost, but like it's grinding on something.

I changed the bov cause it was given to me for free (well, i drove my friend around and that was his way of repaying me). It's a good bov, and i like it..
I basically just wanted something different.
