forged wastegates psi issues?

[IPD]

jfast and sin... the two biggest baboons on this forum.

one who swears he's never coming back, and the other one who threw in the towel and opted for a naturally aspirated 'murican v8.

so I have DR750's and set of these waste gates.(blue springs) how can I be sure I set them rite so I don't have to remove and readjust? I know you all said to pull a vacuum and make sure both flaps open at the same time. but how do I determine what psi they should open at? and why does it matter?

Simple. Buy a Mityvac MV8500 NOT the MV8000. The latter won't work. It only does vacuum not pressure. The MV8500 does pressure. It's super simple to set your wastegates with it and you can't slowly make them open up ensuring they're set to the exact pressure you need. You can also get them at parts stores but they'll have to order it first because they only stock the MV8000 which only does vaccum not both.

He sold that and bought a new Evo and dumped like 7k into a 400hp build.

You need to clarify that really, the link you've posted is for a Blow Off Valve..

Like I said earlier Reds were the only ones that cut the mustard with my Forge Actuators and TD04-16g's..

I went with reds also. No point for me to set under 20psi.
