Might not be the actuator causing the problem. Isn’t there an orifice somewhere to restrict it? Might be clogged up.

 

i ain't following you...

the PD blowers with bypass valves use engine vacuum to suck a spring-loaded butterfly valve open. high throttle percentage (low vacuum) makes the valve close under spring pressure to stop recirculating what would otherwise be pressurized plenum air.

if a vacuum line was to clog/fail, it would result in the opposite effect (keeping the manifold pressurized all the time)

 

Hey Guys! thanks for all your input, i really do appreciate it. I tore into the entire air intake system and found that was to be the problem. First, I have an intake RAM scoop and there was paperbag and road debris that was stuck in the tubing so that was definitely contributing. The major issue was more the intake filter (Volant). The air filter was crushed in in a spiral pattern, almost looking like the engine vaccuum sucked in so hard it collapsed, and the prefilter was caked with dirt and sludgy debris/dirt. It looked like one of the silicone elbows crushed in and crumbled allowing air in after the MAF. After i cleared that all out, cleaned the filter and repaired the elbow, i was pulling 7-8 psi boost at WOT. So problem solved. now i have to figure out what new air filter i want to get since this one is crushed in. I'm thinking maybe a dry filter since it's a weekend car more than anything.

 

Is this a stock airbox?

 

funny enough, i was just talking to a guy at Volant a couple weeks ago about buying an airbox for my wife's 'new' 2001 dodge... but i told him we didn't want an oiled filter (too many dirt roads & trails for us) so we were hoping they could swap their standard Pro-5 for a DryTech of the same size (which i found on their site). he told me they used to have that option with our specific airbox, but a few people kept getting CELs for lean codes because it was flowing too much air for the factory tune.

to that point, i asked him to clarify that it meant the DryTech flows that much higher CFM than the Pro-5 but with the same filtration efficiency... and he said yes. on a side note: he said since i mentioned we're tuning the truck anyway for that + some other mods, they could still swap for the dry filter... but they've had some supplier issues & couldn't build any at the time. his advice was to check back sometime this month.

 

That is exactly when you want an oiled filter is for dirt roads and trails.

Not an oiled filter guy but based on what I have seen that is when you want them

 

Exactly. If a filter used in dusty conditions doesn't get clogged, that's because the dust is going through it.

 

it'll get clogged... but not caked up like with an oiled filter. you just vacuum a dry filter off.
the fabric is woven tighter than oiled ones, too (smaller pores/gaps). Spyder filters described this in why they specifically make their dirt track filters with dry media.

 

Yeah right, it gets caked because it kept all that **** from going into your intake...

 

No, Volant CAI with RAM air scoop
