weird turbo sound?

iretommy81 · 05-09-2008, 06:54 AM

today on the freeway, i was doing 120kph, and someone went to pass me, so i punched it and just after i released the peddle, i heard almost a grind or weird sound! it was comming from the turbo area, and if i pulsate the peddle at higer speeds, it does it.. what is it?

its called turbo bark... something to try and avoid but nothing to be too concerned about.... it is the air surging in your turbo with nowhere to go.. maybe someone can chime in and explain it a little better...

Yeah i think thats what it is. Don't worry about it its normal, but don't do it all the time, hard on everything.

blow off valve is really the only way to get rid of it, diesels lacking closed throttle vacuum, only have one option avail, its controlled by the apps, and is like $600, i forget who makes it.
