I could never hear my turbo over the engine noise. But like I said before, my k24 started to spool around 2,000 and was full 22psi in everygear if I wanted to.

thats interesting the big vnt advocate has had a change of opinion  ;D

but to be fair to the vnt your vanes were not operational.

i still feel kinda idiotic for not trying this sooner.. its a blessing in disguise if you ask me.. i like the K24 to be totally honest..

but i dont like that it barks soo much. it really worries me..

More than one person told you that there was no advantage to running a VNT with stationary vanes over using an appropriately sized wastegated turbo.  However, an appropriately sized VNT with functional vanes is a humongous improvement over any wastegated turbo.

Do you have a full exhaust on it?  I had a K24 that barked significantly when I only had a downpipe on it.  The barking went away when I added the rest of the exhaust.

Perhaps when u let off the gas the exhaust side loses all drive pressure while some pressure is left on the intake side to reverse the flow of the turbo for a second. Just a thought

it barks till its spooled down..

it will bark if you get on the boost, and then shift..

if you drive it like a granny, then it dont bark.

also has no downpipe..

Turbines work how guys?  pressure differential across the wheels, stock intake/exhaust = less pressure differential, open intake/exhaust = more pressure differential.  The more you hear it the better its working.

so now that you like the k24, go even bigger try out that dodge turbo see how that runs, basically the same thing as joshs turbo but with the newer smaller faster spooling turbine wheel.  its basically what i am going to use but i am sticking with the vw .36 exhaust housing vs the dodge .48
