Ok I know the sound of a open dump tube wastegate sounds. But for some reason mine sounds wierd. It sounds like a crazy fast valve tapping. My motor seems fine. No valve tapping there. Its just when I get on it, it makes that wierd sound. Bad springs you guys think? Bad Wastegate? Am using a Tial 38mm btw boosting only 6psi. Thanks for the help.

 

maybe what you're hearing is your engine pinging?

 

Nope, check everything out. no leaks or smoke.

 

make a video, and link us.

If its the niose i am thinkiing of, its normal, they tend to sound like that on lower boost levels.

But there is no way to tell until i hear it.

 

stupid question,
drag kit? mine sounded the same way.

just up the boost, the gate wont open as far making less noise. he hee. j/k

 

nothing is wrong with your wastegate, if you can hold a certain amount of boost that you have it set for then your wastegate is doing it's job correctly.


if it was openning and closing you would have boost spikes

if it was bad and no openning you would be overboosting

if it was staying open all the time you would probably only boost like 2-3 PSI in the upper rpm ranges.

all wastegates sound different on differ cars and motors at different PSI.

sound isn't the best way to diagnose a problem unless it's effecting your performance then I wouldn't worry about it

 

Thats what most of my buddies was saying. Its because am only runing 5psi
