@V8Cowboy I am on day 2 of back to back mpg runs, keeping speeds in the 60~63 mph range. I pulled the tape off the air box, i felt it was holding it back for part throttle performance. I wanted to compare the 2 conditions before any other changes and it is looking like there is a good jump in mpg's compared against the taped box. So with the 68mm TB + OEM air hat, tape in place was better for low end yet with 70mm TB + MIT it is appearing to be better with the tape removed. I may delay the next round of changes... thinking that the airflow thru the airbox could be further optimized for the 1500~1800 rpms cruise range. Which means I may be drilling out the sides of the box some. Ultimately when the cut out is installed the box still is going to need enough flow with the valve closed.

 

Admire all your attempts to eek out a few more MPGs. You're attacking from many angles and the cumulative effect should show some yield.

I've done upgrading of old sensors (still haven't done the crank sensor), new parts, plugs... tire pressure, thinner oils, etc. While I'd like better mpgs, the truck is my daily driver and the only one I've got, since gifting my Honda to my daughter years ago. Truck is now approaching 330K and needs to do at least 60 miles a day, 5 days a week, so my focus is on reliability. I don't want to molest it too much, nor do I have the time. I keep the fluids fresh and keep the old girl purring along, cause the prices of even used cars these days will make a dump truck's mileage look attractive, as long as I already own the dump truck. LOL Getting me to work without fail is what this old girl does best and also best for my pocket.

I keep watching your thread tho... who knows, you may stumble upon something big.

 

I just located a Dodge Ram importer here in the Netherlands, who's selling 2 used Heads and intake of a 2013 Ram.

I asked them if i could just buy the Camshafts and Intake Manifold.

Now i'm gonna sit tight and embrace myself.....waiting for a price quote....

 

You know the intake manifold takes an adapter to get to the 3 bolt TB right? And... will the cams work on our block with the different head setup being 2 plugs per cylinder?

 

Yes i've read alot about it, so i'm going to make my own adapter or ask my brother to help me, so the intake will be no problem.

Also read a lot about the HO cams, they are gaining a lot of torque as well, but are very hard to find.
So i decided to try if i could find 08+ cams, they perform even better and it's a direct swap.
I'm thinking if the HO Cams give more torque the 08+ cams will do even more.

I don't think i'm go through on this though, it all depends on the price, and knowing everything over here is hard or impossible to get i think it will be way out of my budget.
There are lot's of Dodge Rams around here, this is because of the low taxes for commercial vehicles, but almost everyone has a 5.7 Hemi, so 4.7L parts are hard to find.

 

investigate the tone wheel setup with the newer cams, not sure how the cam tone wheel is setup.

Filled up @ 196.8 miles, 17.977 mpg, new personal best on this truck. Temps are ~10-15* higher, rain 1 trip, no winds to speak of.

Mods for last tank = 70mm TB, Airaid MIT, K&N stock air box filter, fuel rail wrapped, Jeep TCM


JTCM got the hook, DTCM installed.

 

Whats the deal with the breathers on this engine? Any insight on it? IIRC the test for blockage is to just pull the hose at the air box, start the motor and wait for a vacuum at the hose end... ?

Have a pair of breather filters on the way that will get installed @ the valve cover hose feeding the OEM breathers (oem's removed)

I have seen my Rams breather plug up and cause a backflow of oil out the turbo, was loosing 1 qt every 1000~1500 miles. Pulled it, cleaned it, re-installed it and oil usage went back to the 1~1.5 qt over the 10k OCI. Found a thread where a guy (I think it was on a hemi) pulled off his breather setup in favor of the filters and reported a throttle response change. Our setup puts the breathers on a vacuum being connected to the air box, seems to me that if you have an ambient air vacuum at that hose end, the vacuum at the air box will fight with it to a point. If it breaths freely it should be better.

 

The camshaft ahs a lockpin for the sprocket and the tonewheel is mounted behind the one a the right, they should be mounted the same way, just a different count 16 ( old ) to 32 ( new ).

 

We don't have breathers on this engine.

We have a PCV system meaning we draw mainly exhaust gasses out of the crankcase and suck them in again back through the air filter and inlet.

When you put breathers on you made an open air system, like on old cars, in my case this means my car will fail inspection.

 

Yes we do... have a look at the left side of the vacuum diagram. They are 2 small cylinders, one attached to each head towards the firewall... This one says they go to the resonator, mine go to the air box...
