PMAS CAI - Need help please!

[GregO]

I’ll have to pick up a few feet of hose.

This might get you out of the woods.
.625” Gates Barricade SAE 30R14 hose in between the barbed fitting ends.

Or slip the .625” hose directly onto the PMAS nipple with a spring clamp over the OD. Ditch the OEM quick connector all together. A sharp utility knife score cut down the rigid plastic to remove the quick connect ends.

I’ll take some more pics of the supplied hose from PMAS GregO. PMAS sent a short section of hose with similar connections to the ones in your pics. Believe it or not, the angled nipple on the PMAS hose won’t lock into place on the nipple in the intake tube because the I.D. of the fitting is smaller than it needs to be. Re,o ing 1/4” from the nipple,and chamfering it again could correct this (might even give a little more clearance too). The factory connector does lock into place, as it’s not obstructed like the PMAS fitting. SMH

Heres my only other thought for you this evening.

Thanks. Keep the suggestions coming. I’m pondering all of them. Where ther’s a will, there’s a way.

A naturally aspirated car the intake track is always under pressure, not vacuum. Atmosphere is 14.7, the air is pushed into the cylinder, not pulled.

Uhh, no. It's impossible to have positive manifold pressure above ATM without some kind of compressor. When an N/a engine is running the manifold will be under vacuum as the measured pressure will be below ATM.

You 100% missed the science.

The decending piston creates a low pressure area, the atmospheric pressure forces air into it.

 

[NGOT8R]

I’ll have to admit that I too am missing the science here. I’ve read that if you install a filter, to do it on both sides, or don’t do it at all. I found this article which put sort of a different spin on it.

Can anyone (especially performance shops) chime in and explain the pros and cons of allowing unmetered air into the engine by installing a filter on the driver’s side and capping the nipple on the intake tube? Is this something that the computer or my tuner (since I will be getting a tune for nitrous), can compensate for in my car?

I know motorcycles are different animals, but I installed a 1275 kit in my 2019 Sportster and vented the crankcase from both cylinder heads to a small filter, (similar to what I was hoping to do on my Bullitt), with no problems. The bike also has an ECM as all new cars do btw with a custom tune. Prior to the build, the factory air cleaner and throttle body would become saturated with oil and would sometimes blow all over the side of the engine and pant leg. I got so tired of that and decided to vent to the filter as mentioned above and the problem was solved.

The mustang uses the MAF sensor to properly fuel the engine. If you add air without it going through the sensor the computer will under fuel or go lean.

The widebands will most likely compensate and add fuel.

I would not trust this under a shot of nitrous, if it goes lean it will cause engine damage.

 

[K4fxd]

On your Sportster example you vented everything to the atmosphere. It did not go into the intake manifold.

Hd uses a map sensor so it wouldn't matter if you did vent it to the intake.

He wants to put a breather on the drivers side and not use metered air.

Uhh, no. It's impossible to have positive manifold pressure above ATM without some kind of compressor. When an N/a engine is running the manifold will be under vacuum as the measured pressure will be below ATM.

Umm wrong. You most certainly can have "boost" without using and compressor. I've seen mine at 115% ve. So thats like 1.15 psi.

 

[WildHorse]

As for IAT's as pointed out, where there's a will theres a way.

GregO, here are the pics of the hose that came with my PMAS. As you can see, the PMAS hose is short by 7-8” and the fitting has a lip inside preventing the fitting from locking onto the nipple in the intake tube, whereas the factory fitting is unobstructed. The kit is not exactly plug and play for 2018+ GT350 intakes, which explains the shorter line And fitting issue. I’m assuming that on pre 2018 models, the fitting on the drivers side valve cover is toward the front of the valve cover, whereas mine is located in the middle of the valve cover.

So the purge solenoid isn’t really an issue.
Are you open to using a longer pc. of .625” SAE 30R7 or 30R14 hose, retain the OEM QC 90 elbow and ditch the OEM fitting connection to the PMAS quick connect nipple.
Cut .625” hose to desired length with quick connect 90 on valve cover end and slide hose onto PMAS nipple with a spring clamp or worm drive hose clamp.
This way the Coyote OEM designed pcv flow circuit is as designed by Ford. Air pulled after MAF and before TB into left side, thru engine block out right side, back into intake plenum behind TB via pcv valve.

The kit is not exactly plug and play for 2018+ GT350 intakes,

PMAS sent you the wrong TB coupler. That coupler is for a 80mm TB not the 87mm GT350 TB. I can tell by the way it’s stretched out over the TB connection.
It should look like this;
