Can anyone enlighten me to what causes turbo bark? and should I be concerned if my truck did have a small turbo bark?? I pulled from a stop sign and saw some wet pavement, well I had to mash the right pedal. When I was done sliding side ways I let off and the turbo barked several times..

 

LOL,,,, you masher you. sliding sideways edit

 

Turbo bark is excess pressure being rapidly released back through the intake, not good on these engines. A VGT turbo without a waste gate is designed to do that, but not a turbo with a waste gate. Is you waste gate turned off or disabled?

 

Hvy, as far as I know the wast gate is operational. Turbo is stock. How can I tell if it is working??

 

Do you have a boost gauge?

 

If you let off pedal easy after hard run, it won't bark.

 

Turbo bark = Dead Turbo...... Don't do it!

 

No I do not have a boost gauge. I have done this before just spinning the tires and have never had a problem. I did in fact have to let of rather guickley though.

 

From what I've been told, it is a more common occurance with upgraded transmissions. I never had turbo bark until I got my DTT installed. Is it bad for the turbo? ---yeah. But like said above, let off the throttle more easy and it won't do it. My turbo barks when I go into lock up. So I lock out OD until my RPMs are high enough that it won't cause the turbo to bark. Then OD on.
