mod questions for 97 5.0 AWD Mountaineer

[Turdle]

This is very good discussion, and bears further investigation. Try this. Call C&L or Granetelli, or any other mafs supplier, and order a new mafs. They will ask a lot of questions, ( injector size, mods etc. ), one of which is about the air intake. If you have an aftermarket intake system, they will match the meter. If you have a custom built or home made, they would prefer to have it to tune your meter. Now ALL I was saying is changing what is in front of the mafs can alter its output signal. Just radiator fan wash is a BIG problem if it hits the filter right. As long as the aftermarket supplier has done thier homework, it will be ok. but as far as your mafs is concerned more air in = more fuel out.
Now as far as the sampling tube goes, on a c&l meter you change it for different injectors. On a pro-m you have to mediablast a resistor, or go with a maf programmer. When I saw the pro-m calibration article in H/R magazine in '03 they had 126 mafs setups for Ford alone. not for different engines so much, but for different air filter boxes. And yes I've seen personally from experimenting with this, An elbow in front of mafs must be at least 4 diameters away from it. I saw 200mv of ac distortion (rich ) running 4" intake elbow instead of my built for maf filter, which is the only one I can run to minimize sample tube distortion.
just fuel for thought.
BTW it wasn't this that burned a piston, it was my quest for leaner, and accomplished through maf tuner adjustment error on my part. ( she was screaming for a second though lol)

My exhaust is the dual out flowmaster. My wife hates it, and I'm slowly getting tired of it. It is very loud. You'll need a good stereo

So having a huge intake and a huge exhaust does you no good if you have a stock throttle body, or a stock MAS.

But are my mod ideas (FIPK and flowmaster catback) considered huge? To me, they are minor and common aftermarket changes that do not require an aftermarket throttle body or aftermarket MAF.

The intake and exhaust are all I'm looking to do now. Goal : grab a couple more MPG and add a slightly more exhaust tone.

Bolt on's only get you so far Computer tuning is key to make it all work together.
Damn granatelli never asked me any of that crap for my 4.0L, just make and year. 19# injectors.
My truck always did run a bit rich....hmmmm

Currently with the 5.0L I am all stock except for the KKM intake element, and my single 3" exhaust (Gt-40 with P heads)

410 if there is a bend B-4 your mafs, try to rotate it ( mafs) to align sampling tube with outside radius of bend. This minimizes the distortion. I do believe colder air is better, and I'm trying to locate my filter outside the engine compartment, but I'm going to have to locate my maf with it.


sagman I know I ramble, but yes do the exaust first. It will compound every other mod. I'd go with the single out to increase torque.
You might like the new sound so much though, you burn more gas,
and do more mods heh heh heh

did you say economy?

O.K I'm openeing another one What about those throttle body spacers? They claim 8 percent increase but I don't have a clue. anybody?

 

[410Fortune]

MY KKM has no bend before the MAS.

My setup is fed cold air via a 4" dia tube from behind the grill, the filter sits behind metal shrouding to shield it off from underhood heat and the fan/turbulance.

 

[Turdle]

Cool. that is what I want.

check this document I found , pro-m is oob now

I don't think the TB spacers do much on a MAF vehicle. Since the air has been sampled, and fuel ratio computed there, accelerating the air AFTER the meter probably won't do much. It may make it more direct/less turbulent, but I wouldn't expect much. I'm kinda curious about the intake plenum spacer that ford racing makes. I wonder if the "heat isolation" it's supposed to provide to the upper man. really makes a difference. It's a pretty cheap thing to do.

 

[410Fortune]

I did that to my 2.9L with Phenolic spacers, worked great at keeping the upper cool.

I have been recommended the intake spacer from FMS as well.
I am just broke as far as truck mod $$$ goes, I did my big project this year, but I would like to up the output of my GT-40, the BII already gets some nice looks

I have a professional products typhoon intake manifold with a 1" phenolic spacer between upper and lower. When engine is at operating temperature, I can rest my hand on the upper. They work extremely well for heat insulation, and add volume to the lower plennum runners ( more low rpm torque) but you have to lengthen your EGR tube which is a custom job.

 

[Phantom5.0]

410- do you have the GT40 intake or the stock "cobra" explorer intake? I've thought about doing the spacer, but decided that while I was there I might as well do plugs and wires. So I'm holding off a little 'cause I don't feel like doing that much of a project yet.

 

[410Fortune]

currently my 97 Gt-40 is stock aside from my filter element, headers, and exhaust.
A new EGR tube from Ford could be made to work, I had to bend mine into shape to fit my TM headers.

I cannot wait to get into the 5.0L aftermarket goodies, just need to hit lotto.
roller valvetrain, cam, intake, chip, shift kit oh my
