My EVO DV is died. It was a great DV and great sound but I need something stronger. I bought turboxs DV but dunno if it can hold 30psi.

Do you guys know any DV that can hold at least 30psi?

I bought one of those silver ones, i ferget what brand it was. It has swappable springs to adjust the load. I think it could have been a forge.

bailey is supposed to be able to hold 30. That's what I'm running, although I haven't been able to boost past 15 due to some other issues unknown at this time

The forge 007 has an optional spring kit. I think the red spring can hold 30.

Yeah the bailey is good for up to like 85 psi. I have one.

Most of the metal bpv's should be able to hold 30psi since that is what the vac/pressure line is for.


I hope your not trying to push the Elim kit to 30psi since it is pretty out of breath after 25psi.

The Turbo XS valve should hold...but you'll need 5-6 washers to increase the pressure of the spring (included in pkg).

I was gonna say what mike said,.....

what turbo do you intend to push to 30 psi

Yes I will try elim to run 30psi. I'll see what will happen. If 30psi does not work, then I'll go back to 25psi.

EVO DV was tested to hold 35psi.

i have one. i called them and said mine was bad. they test it and sent me a new one.

Thanks b00st for the idea. I'll send it to them.

the forge spring kit works with the evo DV. The forge green spring has the same dimensions and spring rate as the spring that comes with the evo ms valve.

The springs dont change how much boost it can hold, they change how much vacuum it takes to open the valve and make up for any pressure drop at the IM vs the pressure in the IC at the bpv.

yep the springs are a waste o' money imo. The stock spring is enough to hold the valve shut during boost since the pressure is similar between the turbo outlet and intake manifold.

But, better he spends $15 to kill his curiosity than spend $130 for a new valve + $15 for a spring kit. ;-)

I tested a bunch of the springs, the only perceivable difference I noticed was boost recovery after shifts. And there was a good chance that was just placebo anyway.
