Van Road Trip MPG report with new IP!

Figured I'd report back my new mpg's with my van with the new IP, to show the difference it really does make!


With my old pump, I was getting at best 13mpg.



Here are my results from last weekend.

9 hour drive each way. 1800km (1200 miles) in 2 days.


16.8 MPG
15.1 MPG
15.5 MPG
16.7 MPG
16.8 MPG
16.4 MPG
14.9 MPG
14.1 MPG


That's with my '85 Extended E350 cargo van, 6.9L non turbo, C6, 4.10's.

I was doing ~60mph the whole trip!


With this setup. The van and empty trailer are around 8100lbs according to a scrap yard scale.

And FYI, these seats are NOT the greatest for long trips!....Neither is my gearing with the C6, was revving so high, I couldn't even hear my AM radio

And on my way back (and yes I drove 1200 miles to go get an old camper cap, 4 hubcaps and a bug deflector ) at the same time I dropped in at an old friends place.

And here she be, on my winter truck!

Nice!!! Gives me some hope for mine....I am seeing about 14mpg with my E250/c6/3.54's. It's the original 25yr old pump....just low miles.

Great result!!

Also forgot to add, since I've done the pump, I haven't had it timed.

Just lined up the timing marks on the pump, and the housing.

But judging from the sound and clatter from the engine, it sounds right on the button.

mine has been averaging 13 lately with 3.54 gears and similar weight to yours. but i've put 65k on it myself, and can only guess if the pump was rebuilt when the engine was rebuilt 10k miles before i bought the van. still need to bump my timing up a little, as i can't yet hear the clatter all the time. i've bumped it up a little from where i found it, but since i'm running blind, i'm only going a little bit at a time

So you just marked the IP gear and housing. Then put the new IP in and lined up the marks. Sounds pretty good....I would be interested to see where your timing is at.

well, you motivated me to look for timing marks tonight. after cleaning it off with a can of carb cleaner, and finding a mirror to get in there, i found my marks and saw that i was retarded by about 1/8", even after my earlier advancements. after loosening 4 injector lines, it was all i wanted to do to get it almost to the factory marks.
and that raises the question: in all i've read around here there's some magical point on the top of the IP where you can supposedly fit a 3/4" wrench and have a nice little handle to pull it around. the only thing i can find up top is that return line fitting, which is scary enough hooking a ratchet strap around the base of and pulling with that, i'm afraid i would break it off it i were to put a wrench on it and pull that around with much of anything. what am i missing here?!

John - that is awesome! I'm super happy for you and the hope it give the rest of us driving bread boxes!

Josh, that area you are looking for is towards the 'front' of the pump and should be close to where the lines are that you are matching up. It is a square block in the casting. There are some good references on here somewhere.
cheers guys!
josh

Did you check your odometer - is it fairly close? You're pushing 2700-2800 RPM's there!

15.8 MPG AVG.

pretty impressive numbers for such a combo.if you look around hard enough on here,it's apparent the 6.9l has it all over the 7.3l as far as economy goes.funny how just 24 cubes really changed things.

who rebuilt your pump?

edit,
hang on a sec.this isn't US MPG is it?

My speedo is 2km/h to fast according to my GPS, so it's pretty close for a mechanical speedo.


Yes all my results are always in US MPG, I convert everything from our silly metric system witch I don't really like to US gallons and miles.


The pump has been rebuilt by Diesellogic, it's a U-haul pump.

Theres a gap in front of the pump, where you can stick in a big pair of channel locks, and turn it with ease, is what I did to mine to position it.

thanks john. i'm seeing this https://www.dropbox.com/s/9riv8q86ua...109_093312.jpg and finally found a link that showed exactly where the wrench was supposed to fit http://i198.photobucket.com/albums/a...ps4a83bbaf.jpg so its now obvious how that is.

i would think the big channellocks may not be the easiest thing around, as we usually have to fight against the lines, i might just have to make myself a wrench that fits it so i can pull it around accurately - i'm sure its not too easy to hold the channellocks on there with one hand while dropping the wrench in the valley pan...

ok, i get it, like this https://www.dropbox.com/s/rv0pmmuiuf...110_000055.jpg https://www.dropbox.com/s/h1zam36fj6...110_000113.jpg https://www.dropbox.com/s/7er3z3u0df...110_000126.jpg
i know, kinda redneck, but it got my pump just a touch past the factory timing marks, where i tightened it down and i'll see how it drives tomorrow. today i still didn't have diesel clatter while cruising most of the time, so still a work in process

IDK. The scientist in me refuses to believe that.... a 5.7% change in CID isn't going to kill your mileage. A lot of gas engines with 25%+ difference in CID can get similar fuel economy in the same vehicle. I'm not refuting the observation, just saying I don't think the 24 cubes are the culprit.
