Default Damn integrated wastegates

How in the hell do i find out how many pounds my WG is? I have a 16g if that helps. I figured shooting compressed air somewhere would do the trick but can't figure it out

bicycle pump i used just to make sure it was working. some have built in gauge or you can get creative and plumb your boost gauge in line with it

lol, youre an airhead.

Get a new actuator. By default they are usually 6 - 8 psi.

Edit: quick google search proves 8 psi.

testing the wastegate actuator with high pressure isn't a good idea. you can ruin a perfectly good one like that

You could have blown out the actuator yourself using too much air pressure. Might have been good in the first place. You're only supposed to test them that way if you can regulate the pressure at the nozzle so yo can adjust it between 3- 10 psi or whatever you like to know exactly what pressure will open it all the way.
