doesnt the stock m42 have a dip in that range?

I have monitored the AFM and at 4-5k there is turbulence in the output voltage,
It�s very noticeable, I would guess it�s there for because of intake design,

Well, good to know. Perhaps the problem is more pronounced with an open-element filter than with the air box (all those little redcers and whatnot were in there for reasons afterall, and not just noise reduction).

yeah man, we're pretty tech savvy, so we could do w/ the wiring and some diagrams or whatever. just give us specs on the maf and other nessecary hardware and we can all fab our own kinda custom system. i have already done that anyways losing the airbox and stock intake hose.

Alrighty. Well I will finish up getting a BOM together. All I really need still are some weatherproof connectors. Anyone know a good source?

Any marine supply places. They are more expensive, but well worth it IMHO. Try WestMarine or Boater's World. They even sell the type that snap together and then have shrink wrap sheathing built in. I usually just get the normal waterproof ones though.

This crimps are much higher quality too!

I have no problem hooking up the converter and connecting a maf to some kind of air filter. I assume the converter is calibrated to work with a specific Ford Maf with a known flow rate, what Ford maf is this since I have one off of an escort working on my car now I was just wondering if I need to find another one specific for your converter. By the way congrats on the success you would be an asset to whom ever employees you.

well... hopefully this MAF thing will take off, and he won't need someone to employ him!

(CONGRATS MAN!)

Thanks guys. Hehe, the plan is to work for someone else for a while after graduation to pay off my $70k in student loans, then see about getting my own business rolling. Of course, I will have my weekend projects that will be products I plan to sell!

The MAF is the 55mm-throughway one found on the 89-94 Mustang GT's, and 91-93 3.8L Taurus I BELIEVE. The PN you are looking for is F1ZF-12B579-AA. Here are some pics of it.

where did you get that MAF? I'm having trouble finding it, even using the part number. are you sure that is right?

jfdublyu · « **Reply #25 on:** May 11, 2006, 10:35:04 PM »

what's the update man? howd your project turn out?

I've read that the cone filters sans airbox does not work well with an MAF because of the way the air flows through them. Actually, I've read that cone filters do not work well at all and cause a loss in power (see the May GRM article I posted where they dynoed it at -5hp). I'd be curious to see how your MAF performs with a stock air box & panel filter; I bet it would be a significant improvement.

Hey sorry about the long delay in response. School has been killing my time.

Well, I got 2nd place with my senior project, so I would say it went well. The car runs well still. I actually swapped the AFM back on yesterday, and wow, the MAF did make a pretty big difference. I still notice a small dip in power between 4200 & 4500RPM, just not as pronouncd.

As for the turbulence issue...I flow tested the MAF with the cone filter strapped onto it and it gave very steady readings. I would have expected there to be some turbulence issues, but there were none. Now, in the case of this very large MAF, if it was connected to the stock airbox I would imagine that there would be problems. From testing, I saw that having any sort of expansion in tube diameter (which there would DEFINITELY be coming from the air box to the MAF) immediately before the MAF caused very unstable readings. The same was true to some extent for reductions in the tube. I am working on a heat shield for this in the next few weeks for my car, but for now the converter will be sold as-is.

congradulations on the success! I use a cone filter anyways that I have routed w/ a strait pipe and a 90deg. bend so that the filter is actually right behind the LEFT brake duct if you are looking at the FRONT of the car. I cut a hole out of the plastic dirt guard underneath the engine on the side so that the filter always has access to fresh air, even at idle. I'll try to get some pics of this. it works really well and i don't feel like i have any power loss even in stop and go traffic b/c of the heat shield and hole.

Awesome!
can't wait.
