I thought that your put up $20 dollars towards an independent evaluation?

I agree, this whole discussion is getting very old.

 

And in so doing he accused me of committing "the second worst sin a Ph D can commit" ...and I'll wait to see if he backs up that accusation before commenting further but if he does respond to my challenge and if you want to stop me from defending my reputation by terminating my privileges on FTE please feel free to do so as I'm sure that nothing could make my wife happier!

EDIT... Of course my $20 offer still stands and it will be sent to whomever runs the project!

 

Perhaps I should have said significant restriction. My thinking is the amount of air intake with a box around the 6637 will still be more than the intake opening in the factory airbox, AIS, or 6.0 container, or the filter you posted a picture of earlier. There's simply more cubic inches of air available from which to draw compared to the others mentioned.

Is my thinking still wrong on this?

 

I think this whole situation is been escalated to retarded level guys.

Perhaps we should all step back and understand that some of these statements cannot properly be comprehended from a computer screen. Tone of voice, facial expressions and general communication is broken down in a forum post. Not to mention some people's want to "flame" or tear down someone's argument for the simple reason of being right or having the upper hand. I have had people say things to me on here and other forums that if we were face to face I would truly be insulted and consider ringing someone's neck.

I think you have been unfairly attacked but this is the way it happens. I do not think anyone meant to accuse you of fabricating results or doing anything immoral, and on that point is someone saying these things a dent in the fact that you are a Ph D in Mechanical Engineering? I think not. Accepting an apology will hurt no one and calmer heads will prevail and this will be forgotten.

Would getting kicked off FTE help anyone. These heated discussions are what make this forum a nightmare and a blessing. Challenging ideas are what lead to the best things for our one true purpose here; to improve our trucks and give us something to cover up the **** website when the mom/girlfriend/wife walks in.

It would be a true disappointment if this thread is shut down when we are on the right track; to find through independent testing which filter set-up truly works best.

Ernest, even though I disagree with your idea on the intake set-up I love your contributions and knowledge. I hope we can set aside our differences and find out some truth.

Well I guess that is my rant. Thanks to everyone that has chimed in and I love the info available here.

Andy out!

 

In answer to the origional poster and his question, I mainly changed to the 6637 because it is a more positive type seal than the stock box. I have had 2 F250s with 7.3. One was a 2001 my new one a 2002. I noticed dusting in both stock boxes. I modified the 01 to clamp tighter, but it just slowed dusting, did not stop it. On the 02 I replaced the box with a brand new stock box, and it started dusting within a year.

I decided then to try the 6637 with 4" exhaust pipe to couple the intake to the filter and used a "T" type clamp to secuer it. After a year, there is NO dust in intake. I have done some testing inside the intake at the AIH port and did not find the temp difference to be significant. I also noticed a slight drop in EGTs with 6637.

The dust in the intake tube sold it for me though, and I am getting AT LEAST the same air low as stock, so I am not going to change it no matter how many graphs and tables I see compared to the stock filter.

I am not any kind of engineer, but a heavy equipment mechanic, and one of the highest premature engine failure causes I find on equipment is DUST.

 

~~YAWN~~

~~SIGH~~

Now we're all giving "haphazard *****-nilly" advice... Nice. Insult the masses that are here to help folks out. I've seen VERY few folks telling someone to do something dangerous to their truck. That hammer head with the Powerstroke Help Videos doles out some bad and/or dangerous advice. Have you gone after him?

On a more constructive note, anybody need a stock rebuilt turbo? I'm about to rebuild my old one & gut the EBPV & stand... It'll be a good deal for someone. PM me.

 

Well there isn't a whole lot of room around a 6637 to build a box and the 60 MPH air flowing through the inlet to the box also has a slight pressure drop associated with it. However I want to again make it perfectly clear I recommend that everyone who's using an "open element" air filter of any brand put a box around it with an inlet leading to cooler ambient air. An inch H2O or so increase or decrease in air filter restriction doesn't have much significance but a reduction in air filter inlet temperature is highly significant.

 

I hope everyone can see the difference between my actual quote and Izzy's made up version!


Well unfortunately I've seen more than a few and I wouldn't mind pulling up some exact quotes as examples if anyone's interested but I'll need to get prior approval from a moderator first!

BTW I responded to each and every one of the issues you raised in your initial post that got this whole mess started up again and since you've never disputed those rebuttals I assume you agree with their technical merit!

 

Do you have a PhD? In what field?

 

And the difference is?? I said "masses" and you said "a lot". So now you're going to argue semantics?? Give us a break, Gene. I'm done with this and you. I've tried to come to even ground with you, apologizing when I made mistakes, but apparently you can't do that. People can be right and still be *********s, you know. Trust me -- I worked with quite a few. To quote a rather famous Ph.D., "Do you wanna be right or do you wanna be happy?" There must be a way for you to impart your knowledge without ram-rodding it or making it seem like everyone else are idiots. I think that's what some of the folks are trying to say, Gene.

The 6637 isn't for everyone. But for a lot of us, it works extremely well. If I towed frequently, I might put a box around it or go with the AIS. I like the whistle I have right now, but pulling 12 hours straight might change my mind. I can see how pulling over the Grapevine with a large tow-load could make someone look for different solutions (and yes, I've been through there).

Good luck.

 

Well I was just getting ready to send you this as a PM because I thought it's best to let this thread move to the bottom of the play list and stay there but since Izzy just bumped it back up to the top again I decided to go ahead and post it in case someone might get the misimpression that I wasn't polite enough to respond to your inquiry!

All of my degrees are in Electrical Engineering and I started off with a BSEE from Washington University, St Louis, MO in 1965, then I worked full time for 5 years before starting my MSEE in 1970 at the University of Maryland, College Park, MD, which I received in 1972, then I worked full time as I finished my Ph D EE there in 1976.

Here's what I posted on another truck forum a while back as a prelude to some analysis I did there...

"I'm a 66 year old engineer whose retirement hobby is analyzing topics that interest me and I enjoy sharing these results with others. I used to analyze for dough but now it's just to know! I often find when analyzing a topic using math and equations that many things which I thought I knew about it turn out to be only partially true or even totally false. I realize that non-engineers don't like equations and such but you just can't adequately understand and explain some things without them. I'll try to make equations as easy to understand as possible and here's some reasons why you might be interested in putting up with them..."

 

You went to WashU? I go to UMR down in Rolla.. I think this is the point where I'm spose to make some little jab at you for being a WashU Engy haha.. Just kidding.. that is really cool tho. I removed all the electronic switchgear from WashU in the late 90's. Beautiful campus!!

Did you grow up in the STL area?

 

I was born and raised there but I left in 1969 to explore the rest of the country and wound up in MD. I stop by St Louis and Lake Ozark to visit friends on most years during my annual coast to coast migration.

 

I've had the same experience. I have run the Ford AIS and the 6637. When I monitored real time intake temps & manifold temps there was not a significant difference in temps at all while towing our 31' 5th wheel. The only time I saw an increase was during idle at a stop light, but once running down the road all was good.

 

I love this site for the amount of information provided and the great amount of generosity people have to offer to each other but I am sort of shocked at the child like behavior in this thread.

PhD or not, there is no excuse for being childish when an apology presents itself.
