6637 mod and orings done today, but have question???
Well Gents,
Got my 6637 (Baldwin) mod done today and replaced my orings in my fuel petcock valve... Took longer to remove the dang petcock then it did to R&R the orings...
Would like to thank, Tom Courtney for the Orings. Some one on here gave a link to his ebay web site and I had them here in like 2 days, with great instructions to boot. Tom thanks for the rag below the valve trick, saved my butt twice.
Also I plan to do the CCV mod ASAP, my turbo boots are soaked with oil at the intercooler. I could not believe the amount of oil that goes thru the turbo and intercooler and back into the motor. Yes I know that it gets burned up, but OMG thats allot of oil...
I have a question about the placement of the AFI, has anyone thought about or tried drilling a small hole in the intake boot that runs from the AF to the turbo??? I was thinking about this after I had installed it in the back of the AF like Ron did. (I hope that where I got the idea. If not, sorry and thank you to the guy that did it)
I was thinking that if I drilled a small hole in the elbow right after it leave the AF in the big none ribbed place on the corner. Get the OD of the AFI and drill a hole a slight bit smaller install the AFI and maybe use some RTV just to make sure that you have a good seal.
This would solve two problems with the AFI and where to install it and placement for a good vacuum on the AFI.
#1, Once installed ,you would not have to worry about drilling a hole in the end of the AF every time you changed it out.
#2, The area that the AFI would be placed would give it a true vacuum reading on the AFI.
#3, Also seeing it would be a snap, as it would be right out front.
Just some thoughts, so what do you guys think???
Props go out to all the guys on this web site...
Doc.

Are you talking the filter minder or the intake temp sensor?
Filter minder - Wouldn't do a bit of good to install it bc it is not calibrated for use AFTER the filter.
Intake Temp Sensor - Would be a cleaner install, but no known performance gains.
This topic has been discussed et nasium the last couple weeks. There is a lot of good info if you go back a few pages or use the POS search option.
Putting the air filter indicator in the elbow sounds like it would work but since it would be in the area of fast air flow, I'm wondering if it would give a false reading? (Venturi effect.) If it would be in the end of the filter, that would be "dead air" space with no appreciable air flow which would give a truer vacuum reading. I understand what you are getting at as far as not having to drill a hole in the air filter each time though. Would putting it on the inside of the elbow put it in an area with less air speed or a little further down the tube? Just thinking out loud. Need Gene on here to evaluate this for you.

If it has wheels and an engine, you have my attention.

I guess I don't understand your "after the filter" comment. Are you saying that the filter minder isn't calibrated to go between the filter and the turbo? Why is it installed there in the stock housing?
How can it tell you anything if it isn't installed after the filter?

Take a look at your stock box. It is installed in the box before the filter. Cowboy Steve from the OBS forum explained this to me in excellent detail to me before I was so "knowledgable," but I will do my best to explain.
The minder in the stock box is before the filter so when it sees a certain amount of draw on the air in the box it will begin to suck shut.
NOTE: This is the same way AFE has thier setup. It senses the lack of pressure in the box before air is drawn through the filter.
In the 6637 drilled in the filter or in the "transition pipe" it will be located after the filter. This will require a different amount of pressure to suck the mider shut bc of the different location.
With that being said...I am wrong...I must have understood wrong Go to the OBS forum and look for him. Powerstroked 16XX or something like that.
I don't know about your stock air box, but mine had it installed right next to the intake tube in the lid, after the filter. There' no way it could function before the filter.Here's a picture

Like I said it was just something I was thinking about. I know that there are some people on this board that will try just about anything once. And I was not for sure if anyone had tried this before???
Also,it would be cool if there was a aluminum pipe that we could get that would replace the rubber hose that runs from the AF to the turbo... Has any one built or check on this???

I too must respectfully disagree. Both of my PowerStrokes stock air boxes have the filter minder AFTER the filter. This is the only way that they can work. The restriction in a dirty filter causes more post-filter suction thereby pulling on the actuator in the filter minder.
That being said, the one in my E350 van never showed any change in indication and the filters were absolutely filthy. When I did the 6637 conversion on my Excursion, I didn't bother with the filter minder. #1 I learned that I couldn't trust the thing and #2 you can look right at the 6637 and see how dirty it's getting.

actually the filter minder is not calibrated for the higher air flow of the 6637. It will not move with the 6637. The correct part is the filter minder that is calibrated for the AIS system (the stock and the AIS use 2 different filter minders)

Actually calibration depends on where it is installed. Probably neither filterminder is calibrated properly for where most guys are installing it in the 6637.

I was wondering about this myself. Do the spirals and kinks in the rubber hose have a purpose? It doesn't look like it would be too hard to replace the section between the AF and the CCV piece. I believe it downsizes in the section from there to the turbo.
