Does anyone know what pressure the stock wastegate actuator opens at? I'm not asking for the stock boost level. I want to know what pressure the actuator will open at if it had a direct connection with no boost controller being used.

 

Your best bet is to test it with a hand pump. I doubt anyone else who posts this kind of info has tested it.

 

I measured this today, it's roughly 14.0 psi. I'm making another thread in a bit to show pressures after the actuator rod it turned as well.

 

yes please please some more info would be greatly appreciated

All the info is on page 5 and 6 of the above thread.

 

12psi

 

following. keep us posted.

 

Best way to tell is run a small hose right from the turbo nipple to the WGA and go do some pulls and watch your boost gauge. Or just turn your MBC all the way down.

 

I bench tested it with an air compressor and a pressure gauge. It cracked around 14.0 psi, but I can't gaurantee it's not 13.8 or 14.2 psi, because the gauge resolution isn't fantastic. Pictures and document are in the link I posted above. With a better gauge I can give a more accurate answer.
