BoV suggestions (flutter dump w/ stock BOV) - Resolved w/ Dodge Mod

I've noticed a flutter from my current BoV when shifting at higher boost levels. I'm guessing that my new cams have lowered my vacuum at idle enough to render my current BoV obsolete. And considering the BoV itself appears to be stock....

So, what is a good option for me? And Evan, I know you are reading this. Should I get a new MBC while I'm at it?


Thanks to all.

When I was looking I liked the Turbosmart. I have their MBC now

part number: TS-0203-1226

I still may get it.

At higher RPM and low throttle my bov flutters and makes the car buck... or is that my WG?

Cams won't change how well a BOV works. Idle vacuum is not the same as going from boost to vacuum, regardless of cams used.

To this day I swear the 1G valve (modded) is the king of valves to use. It's fast moving, cheap, NOT annoying, and can be modded to hold 30psi.

That's my opinion. I noticed a little low throttle surge with mine. I set up my link to switch the lines on the BOV and it performs flawless. Opens fast under light load like stock, but I've hit 27psi and had it hold solid. Never had a 1g BOV fail or quit on me in over 10 years. They are cheap and plentiful and lets you put the money somewhere else. My biggest praise is that it's not obnoxious loud and is pretty quiet, but still noticeable.

I suppose I should describe the issue, too. Car holds boost just fine up to 23psi. However, when I shift at higher boost (lower is ok), I get a fluttering sound like psht psth psht. no notice issues in drivability.

After watching some youtube videos and listening to the BOV sounds different cars with different problems were making, I think I can say with a fair degree of certainty that I'm experiencing flutter dump.

A new BOV will most certainly solve this problem. Will the dodge mod solve it as well?

Dodge garage mod here. I love it. Holds everything I throw at it and works flawlessly. I was planning to connect it to a solenoid through ecmlink but its not ever needed.

Quoting coyotes:
Have you crushed it yet?



No, but I suspect that doesn't fix my issue. If it was a spring tension problem, I would expect to hear flutter while spooling. I get to 23psi with no issue, and hold boost at around 21 through the RPM range. I'm only getting flutter when I clutch off of high boost.

I suppose it could be leaking and I wouldn't hear it?

They hold more boost when crushed. It seems they start to leak over 17psi, but who knows if that is causing your flutter issue. I can't say much more out of not knowing enough on the topic.

dodge mod fixes the issue properly. crushing it is old tech and not a consistent fix.

They will also leak with a dirty sealing surface. I have taken mine off and cleaned it after a blt and no leak up to 35lbs with a dodge mod.
