Mass Air Flow housings

[Brandons]

I do wonder, were do they get the measurements? From the smallest diameter in the whole housing? Or the smallest end? Mine looks like it is a bit smaller inside than both ends are, if thats the case then mine would be about 73/74..

I think the trick here is to find that magic diameter for your engine and not go any bigger. Of course there's variables to consider when there's other mods like a super charger or turbo.

From my understanding, And from being a manufacturing engineer, the stock design was probably (ID Diameter) put right in the middle of a tolerance range. When going to a 73MM ID from a stock 65MM?? (Please correct me if I'm wrong) 4.0 SOHC MAF, you're right at the high of this tolerance? Then again, that's my understanding and I could be just bull crapping.

I don't think the MAF sensor cares what brand it is as long as it's the Diameter is not to big. If you look at the C&L housing you'll notice that there's a little ID profile that directs air to the sensor wires. I'm assuming this is because the Housing is larger than stock and this is how you get away with using the stock sensor. There's engineering in there and that's why the price is where it is. That part could be made for 50.00 bucks depending on the qty's they sell. So I suggest everyone that sees this to buy the C&L housing and make the price go down for me. Then I'll buy one. HEHE

 

[Jakee]

Correction. There is no special engineering on the C&L housing that I see. So why is the price so high?

 

[conig]

the hole the sensor reads through has to be calibrated, in relation to the size of the sensor housing. the drop in housings(no new sensor just the tube) are mechanically calibrated by the diamter of the read hole verse the sensor housing itself.

it works just as good I however have no idea what correction factor or how they come up with the dimensions.

well if you can find the site, pro m makes an adjuster they call the optimizer I was looking at one yesterday. I had one on the stock sensor of my svt contour and tweaked almost ten horsepower out at the wheels with it. you could use that to dial in your present maf sensor.

They have been out of business for quite a while.

When I take my MAS out, the housing has a "Straight" thru design. In other words, there's no little hole in there to calibrate incoming air. When you look at the picture of the 73MM C&L housing, it's the same way, and it uses the stock sensor. So, I don't see where there's any Mechanically calibration going on.

The stock MAF sensors have a fine mesh screen to keep dirt from accumulating, while these are completely open. I'm sure that the sensor will have to be cleaned out more often.

The one i got has a pillar in the center were the mafs elements are, same mafs as the factory one too.

ive found dyno results like aldives are not easy to find for the 5.0 he has posted alot of good data.

I've got the same MAF body that Aldive does. Used it on my old SOHC V6 equipped Sport. I seem to recall noticing a difference but I honestly don't remember how much. Doug at Bamachips sold it to me and didn't use a hard sell approach at all. In fact, he was pretty pessimistic about aftermarket MAF offerings from Granatelli and Pro-M. He sent it to me with a full money back guarantee (including shipping) if I didn't like it.

When I traded in the Sport on my V8 equipped Eddie, I moved the C&L over to my new ride, I've been using it with my custom, Volant based intake and I pretty much had it on from Day 1 of driving the Eddie that I can't know for sure if it made a difference. The Eddie runs like a top and I've done lots of mods so it's really hard to tell which mod has done what.

No plans to dyno any time soon. No AWD dyno facilities nearby. :thumbdwn:

Here's some pics. It's a 73mm, an upgrade from 65mm. I did lots of research and this was THE part I wanted. I called Doug and straight up told him I wanted it, didn't ask opinions or anything, and he told me he's had reports of 5-7rwhp. I painted the grey C&L black to keep everything else in my engine bay looking "super stock" I also have modified my Volant box by cutting out the sides. It leaves the heat protection and the cool c/f cover, but draws in cool air from the headlights and fender. Like I said, I'll have dyno numbers this weekend hopefully. All I know is my butt dyno says it was worth the cost and that's good enough for me.

Not true.

aldive, can you tell me what part number your air filter is. i want to buy the housing and that new amsoil airfilter.

Here's some pics. It's a 73mm, an upgrade from 65mm.

Your setup is VERY similar to mine. I painted mine a dark grey to tone down the stock drab silver it came in, and blend it in with the rest of my setup.

Consider the EAAU3560 too. A few bucks cheaper and the filter has more surface area.

It's a tad shorter, but it's wider. Dimensions are all at Dead Link Removed.

thanks

Does anyone have the ability to measure the smallest ID of the C&L housing? I know that's asking a lot but we could make more since of where the 73MM is coming from. If the measurement is not = to 73MM then the smaller id is not where the measurement is coming from. This would clear up a few questions and help everyone understand.

I guess my stock housing is different. I don't have any screen at all. The only thing I see when I take the sensor out is a straight thru hole. I do notice one flat at the top where the sensor mounts. I don't notice that on the C&L. Maybe this is where the performance gain is coming from. That and just being bigger.

Well, no dyno numbers, but I do have this:

Well, I like the truck.

My stock EX has been able to do that from day one and without power breaking..Just build up the RPM's to around 2 grand and punch it. It'll spin for 25 to 30 yards before gripping. But this is not a good thing if you plan on getting down the track first.

But like I said, nice truck.
