MAF location in relation to TB

Ok, so I'd like to know if the 4.6 DOHC engine cares how far the Mass Air Flow Meter is located from the throttle body.

Short story: I'm thinking hard about adding a cowl induction scoop, and would like an actual reason for adding it, so if I can devise a way to put the MAF and an air filter almost on top of the TB, then I'll be a real happy camper. Plus it should clean up the look of my engine compartment by getting rid of the lovely tube that extends over my right valve cover.

Thanks for the input in advance........

Hey joe i sent you pms what the deal on the cats got the money yet, its their at i guess the front office
 
RE: MAF location in relation to TB

nope, as long as ther eare not any leaks after it.

"EXCELLent....!" (Now I feel like Dr. Frankensteeeeen). I will investigate butchering things to see how well this works. Thanks again!
 
RE: MAF location in relation to TB

when i had my 95 cougar i move the maf into the hole where the air silncer was w/ the cone and it made it lope like it had a carb on it, sounded nice if you let the car sit while on it would start to lope, i dont know how it did it

Hey who said you could steal my idea? LOL! Seriously, I have/had the same idea a few months ago, but being here in Afghanistan, I can't work on it. I think it would work great. Take advantage of the vaccuum at the base of the windshield..old school stuff. I was hoping to be the first, but if you do it, please post pics. I think it's possible with a flat K&N set at a slight angle (\) in a cowl hood. I'm hoping to not have to go as high as 4". I like a lower profile than that, but if it has to be, it has to be. The biggest hurdle I could think of was still being able to get the air into the MAF at a relatively straight line to avoid turbulance. Are you doing this on a gen 1 or 2? Mine is a gen 1 ('96).

Ain't that the way it always is? You get an idea, then somebody beats you to it! Mine's a Gen I, 1994. One of the biggest problems we're gonna have is the blasted rear seal for the hood -- you know, the one that has the plastic cover that sits around the wipers? The TB sits right below this overhanging P.O.S., restricting room, and I haven't decided to cut that piece up yet. Until I get a super bright idea on how to accomplish this project using the original intake, it may be worth while to just get the Cobra intake (or any other intake that moves the TB)and work from there. The cowl will give us the added clearance for that intake anyway, so why not?

Is there anybody interested in building an intake from scratch for us crazy SOB's who just "gotta have" this???

Yes, I know. I want to start out with another factory type intake duct and cut off the TB end and fabricate something that comes straight forward, the up slightly. It's gonna take some work, but I think it's possible. If I can get the time, I'll PM you with a drawing. It will be crude since I don't have my beloved Photoshop out here. I'll have to use MS paint. I think we could work this out. I honestly feel that ther would be a couple of HP to gain if it's done correctly. Please, keep me posted. Thanks.
 
RE: MAF location in relation to TB

Ok, Tony.

I'll need to spend alittle more time under the hood, adn if I come up with any bright ideas, I'll let you know!

RE: MAF location in relation to TB

I had thought about doing a ram air type design last year (well it was more of a shaker hood design i guess). A worthy idea is to turn the entire intake around so the TB is on the front. You'll have to move the alternator using a relocation bracket, similar to the design from the tasca-mark. I beleive all the bolt holes wouls still line up. I stopped looking into it after a while, it was more work than I was willing to do for the little gain.

Now that sounds viable. Who has info on the alternator bracket, and can anyone confirm turning the intake 180 degrees?

Hey Tony, I came across something pretty interesting. Unfortunately, I don't have access to a scanner (and I don't know how much heartburn Hot Rod Magazine would have with one of their pics being posted w/o their permission), but if you can get ahold of a copy of HOT ROD February 2001, on page 88 there's a picture of a Mark motor stuffed into a '49 Merc ("When Worlds Collide"). (Incidentally, they picked the DOHC over a 500 Caddy!) It's definitely a Mark VIII motor, and appears bone stock except the air intake. He has a custom pipe the shape of the TB coming straight up and immediately into a 90 degree bend straight forward. The tube reduces to a round shape with the MAF attached to that via an extremely short rubber hose. A short aluminum tube is boltet to the front of the MAF with (TPI Camaro?)air filter next. The air filter extends beyond the alternator, with the MAF directly over the middle of the intake. A simple bracket goes from the MAF / Alum tube lower bolt to one of the old "goofy plastic engine cover" mounting studs next to the fuel rail schrader valve. To hold the air tube on, there's a shaft with a knob on it protruding straight up out of the 90 degree bend directly over the TB where the factory mounting bolt would go. Hopefully, you'll be able to locate the picture somewhere.

I don't know, but I'd say the '49 Merc has plenty of hood clearance where the stock Mark VIII hasn't room for a 4" diameter intake tube. But done tastefully, I suppose the hood could be radically changed.

That's the biggest hurdle I had. Art design isn't exactly my strong point, but I couldn't find a way to make it look nice on such a classy car. I'd love to see designs others come up with.

BTW, it was ponyfreak who told me the holes would line up on the intake, I'd ask him for confirmation.

Boy, howdy, does the Merc have the clearance. No way it could be done on a Mark without a bump on the hood. I really wish I had a way to display that picture!
 
RE: MAF location in relation to TB

Doug,
I'm sure I have that mag at home. In one of the threads on this board, there is a picture of a grey Mark with a cowl hood AND an SVO hood scoop grafted into it. Might be in the "Glove Box" section of this board. I'm sure that would provide the clearence we are looking for. I thought it was a tastefully done, IMHO. I'm seriously glad you are looking into this. I feel helpless as of this moment due to my location. Thanks for the info.
 
RE: MAF location in relation to TB

yea so with a cowl hood...how do u prevent rain from entering the filter and fukin with your engine??? cuz im half way thinkin of doing that to mine 2
 
RE: MAF location in relation to TB

Yea the Mark VIII and cobra manifold/IMRC's will line up on the heads when turned 180 degrees. You just have to make another alternator bracket to make it work. I think the fuel lines will work too with no problems. You might get it to work with the stock hood. Maybe. Definatly would work if you rewelded the TB plate on at a 60-90 degree angle. That is easily done. That is what i would do if I were wanting to venture into this teritory.
