This post was updated on .

Today I was talking with Scotty The Mad Porter and he suggested that I take the "silencers" out of Big Blue's to-be air intake system. I thought "I've heard of doing that, but where was that?" So I did some searching and found it - a magazine article called Project MPG.

I'd found a copy of this online some time ago and downloaded it then, and after skimming it again decided y'all might enjoy reading it. Here 'tis:

EDIT: There appears to be a problem with iOS devices seeing this file. So if you are having trouble you can download it here or read it on the Four Wheeler site.

I've been referring people to that article for decades because it's very objective, and debunks a lot of mythconceptions. The link to the website is in this caption:

That article disappears when I scroll down.

Dane - Put your cursor in the window of the article when you scroll. Then you are scrolling the article and not the web page. Put your cursor outside of that and you'll scroll the web page.

Steve - I've seen it several times over the years, and even downloaded it. But it took me a while to find it where I'd saved it, so thought I'd share it here so all could see and I could find it.

Yes, it does debunk several things. For instance:

Inlet Air Temp: The best power and MPG was achieved with a K&N air cleaner element in the stock box and the whole inlet air system wrapped with insulating tape. Using a K&N open air cleaner element sucking hot air actually hurt MPG compared to stock.

Overdrive: A Gear Vendors OD behind the C6 improved highway MPG by 18%.

Exhaust: They saw a 2% increase in MPG as well an increase in power and decrease in elapsed time on acceleration with headers. But I get lost in exactly what system did best, although at one point they say a single exhaust pipe does better than duals.

Anyway, and intriguing write up.

Interesting! When I scroll up it’s gone. On an iPad.

Dane - Please try it again. I may have learned something. I had the width set to 100% of screen size, which worked perfectly on my Windows devices. But, on Janey's iPad Pro and my iPhone X absolutely nothing came up. Zip. Nada.

So I changed the width to 95% and magically it now works some of the time on both devices. It comes up initially, but if I try to do much with it, like scrolling around, it goes away until I refresh the screen. Then it usually comes back, but not always.

But, I'd like your observations, please. Something's not right, but I don't want to go tilting at windmills until I have more input.

Re: Project MPG

Ok, when I click on the time the last post was made and then go up it is not there.

When I click on the topic it’s there and I can scroll the magazine but I only see half of the page. When I scroll down to see the whole page it disappears.

Clearly there's a problem, Houston.

That's me - CONFUSED! And CONCERNED! I'm now wondering how many of my embedded documents are not usable by iOS users.

Have you had similar problems on other posts? What about pages on the documentation part of the website, like the Driveline/Axles page, which has embedded docs on the Instructions tab?

Gary,
I think Lima Big Block and fuel economy are oxymoronic.

Yes, you can drive like a grandma.

You can drive with a vacuum gauge.

Or you can beat the snot out of it and get 8.5-9 mpg like me.

I'm sure you'll be more conservative, but I get the same sitting in bumper to bumper traffic doing 10 mph, so why not?

Your 3,55's will help a whole lot.
But it's still a 7.5l engine in a heavy pickup with barn door aerodynamics.

Jim,
Lil'Red is a '87 F250 HD, 4.10's, 1356 4x4, Zf-5, 3G, PMGR, Saginaw PS, desmogged with a Holley 80508 and Performer intake.
Too much other stuff to mention.

Jein. 460/7.5L should not be used in the same sentence as "economy". But, I'm trying to improve things somewhat. If I can get it to 14 MPG at 65 MPH running light I'll be happy.

Yup
But it seems I'm doing 10 or 85 depending on traffic.

This is the first time I’ve seen this happen.

The others you mentioned have always worked.

Edit: went and tried one in axles and it worked fine.

Ok, lets see if this works. I OCR'd the file and then optimized it. That reduced the size from 12Mb to less than 6Mb.

And, now it appears to work on Janey's iPad. But, it doesn't work on my iPhone X. So maybe it is too big to work on an iPhone but small enough for an iPad????

Dane - does it work for you?

This post was updated on .

Ok, one more test. For this one I removed the pages that had the magazine covers. There were 4 of them in the 23 pages, so that now makes it 19 pages and 5.07 Mb instead of the 5.95 Mb in the edited 1st post. (The original file size was 11.8 Mb.)

Does this work on the iOS devices?

No, that didn't work. Apparently by having both the reduced file in the first post and an even smaller file, albeit still 5.07 Mb, in this post it killed it for Janey's iPad. So, I took it out of this post and put the smallest file in the first post. Let's see if that works.... EDIT: Yes, sorta. Haven't gotten to test the iPad as it is in use, but the iPhone X now works in landscape if you tap the screen several times where the article is supposed to be.

Dane?

You could just embed the link for anyone who can't view the file here.

Thanks for the idea, Steve. I've now added a download link in the first post.

But, I'd still like to figure out and fix whatever is causing the problem. In fact, I'd like to know what problem others are seeing.

Nope, it disappears when I scroll.

Edit: tried tapping where it’s supposed to be and no joy!
