So it turns out, I was mistaken, one of the valves is for the PCV system, but my 8.1 has an internal pcv system and isn't acceible. TireRod told me to tap vaccum and put a one way check valve on the the tapped. So can I use this regulator, e-valve, thing on another wastegates?

 

anybody?

 

Ya, you should have no problem controlling 2 WG with it, just T into both hoses AFTER the valve and regulator for the second WG and it will work fine.

 

OK, I have decided to go with two small wastegates. If I do do this, what springs should I use? I'm not sure how to figure it up with two wastegates. i am going to take mine apert in a minute and see what spring it has.

 

i like to go a little lower on the spring than the minimum boost i want. lets say your lowest boost setting is going to be 8psi. i would get the 6psi springs. with a 6psi spring you could see anywhere from 5psi to maybe 8psi. then use a controler to get it right where you want it.

then figure whatever you see for boost on spring only you should be able to go 2-3 times that amount with a boost controler before you have to get a higher spring.

 

So say I want to have a low of around 4-5 psi and a high of 8-9 psi, I should get like two springs somewhere between 2-4(if they are made that low), and then use the controller to get my 8-9ish lbs??

And the box the gate came in says " .4 bar "

 

i think the lowest they go is .3bar. that should be right in that range of 4-5psi but depending on the set up could be a little higher than that. you wont have any problem geting 9psi out of it when you want as long as the turbo is large enough.

 

So can I do this: Leave the .4 in the gate I have and get my new gate with the .3 or whatever the lowest is. You know, mismatch them, or will that really f*ck things up?

 

i dont think you will get the low boost you are looking for if you dont put low springs in both of them. i see above i posted up about a .25bar spring. i would get a set of those. with the size of that engine you will need to by pass as much exhaust as you can to keep the boost down.

 

Why are these springs so expensive and where is the best place to get them??
