What does your turbo sound like?
I am not talking about the whine we all love.
My first PSD had a turbo that did a weird harmonic thing at about 55-60.
My second PSD only had the whine.
My CTD has the whine but I am thinking it also has a harmonic too.
Anyone else ??
Thanks, as this is to isolate a drivetrain noise.

If I read it right, I hear a harmonic on the turbo just over 33psi.. It tends to go away once up against the wastegate at 35-36... The pitch of the turbo definitely changes over the 33 mark.. If you have a modified turbo, like a PDR 35 the pitch changes to a higher Psi mark. It must be due to the mapping of the compressor wheel.
