do wastegates make noise? i have a delta and at higher rpms my motor is making a noise that sounds like vwoooooooooosh. sounds like air is escaping somewhere or sort of like a vw and it lasts from like 3.5k to the top. anyone know what is making that noise?

 

WG Not plumbed back into the rest of the exhuast?

Then yes it will make this sound.

sound's like a loud insane "fart"
