5.0 Perf Intake Mods

[ponycarlover]

I replace my coils for the reasons that you(^) mentioned as well as at the time I was experiencing the "ghost" coil misfire/malfunction check engine codethat is associated with late model 5.0l x/mountys so I replaced the coils in attempts to fix the problem soon after I learned of the "ghost" code.

Here is a link to a quick comparison: Accel vs. MSD

I found with the Accel I gained a little better idle and a small change in throttle response. Now granted I changed the plugs and wires at the same time but the improvement was more than what I have experienced with performance plug and wire replacement in the past on other applications. Improved idle is proven to aid in increased mpg another reason I went to aftermarket coils.


Ill post parts list for the intake after work.

I wasn't able to make the link work (that comparison only works on your PC because cookies were set). I was able to duplicate the comparison though. "Maximum" voltage of 40,000 v for the MSD vs 42,000 v for the Accel. I'm no tech expert and have no clue if 2,000 v makes a difference especially since many naysayers suggest that a coil pack change does nothing in our applications. I did NOT change my plugs and wires at the same time so our results are not really comparable of course. I was more curious about your comment that Accel have "better response" (presumably than MSD). That Summit comparison doesn't really show that (or at least I cannot interpet it from the stats). You've got me on the "value" front, although MSD and Accel were roughly the same price where I was shopping (I was able to get the MSD for less than the online price advertised in most places including Summit and I never paid for shipping because a local shop had them).

Nice work on the intake. I put together a "custom" intake too, but instead of rigging up my own parts, I merged parts from two different intake systems and married them with my C&L MAF body and totally overbuilt couplers for looks only (they're made for turbo/supercharged applications). I love it.

I like your intake what kits did you use to make yours?

I made mine from a cheap ebay kit almost identical to this:http://cgi.ebay.com/ebaymotors/96-9...tegoryZ38634QQihZ014QQitemZ330057070919QQrdZ1

(the tube has to be cut to fit with the other part I used for this application.)

A heavy duty drain clamp like this:

(You can buy them at Lowe's or Home Depot or most other hardware stores. for 5-8 dollars. Mine are stainless steel shielded.)

I also used a ABS 45 degree street elbow:

(you can find at most places that sell plumbing supplies)
I also used a K&N Filter part number E-1796 same as used by 96-99 Chevy truck with the 5.7l.

You also need a vacuum fitting to reconect the crank case vent tube to the intake. I drilled a small hole and used a double barbed elbow.
If you need help on how it goes to gether I can give more information.

interesting.
i'd be interested in hearing which, if either, offers any performance benefit.
thoughts?
thanks,

Celly,
that intake system looks awesome. are you pleased with the performance. do you parts numbers/list? where'd you get everything.
thanks,
philo

Very pleased with it. You won't find part numbers however. I started with a Volant intake kit for a SOHC Explorer (the ride I traded in on my Eddie Bauer). The intake tube on the 5.0 is a different shape, so I scored an entire 5.0 intake kit from a company called "ASMI" (they sell on eBay), and took the intake tube from that setup for use with my Volant. I still have all the other parts. ASMI's intake kits are effective on their own, but a bit on the cheapo side. The couplers and clamps come from a company called "High Temp Silicone" or something like that. I just replaced the couplers that came with the Volant (which were fine on their own, I just wanted something different purely for cosmetics). The C&L MAF body was ordered through Bamachips (was used on my SOHC Sport as well) and the 5.0L badge was scored on eBay. I also replaced the "oil and cloth" filter that came with it with a non-oiled one from Amsoil.

I wouldn't recommend this route. It's VERY expensive to do it this way. The Volant kit alone retails for just south of $300 normally. The only reason I did it was that I already had the Volant and really didn't want to give it up. I feel it's the best intake kit on the market, out of the box.

If you don't want to build a good intake setup from scratch, "MAC" sells a great kit for around $150/shipped. I think "Proficientperformance.com" has the best pricing on them.

isnt the MAS sensor supossed to be a little further upstream from the throttle body? It was my understanding you cannot mount it on the throttle body like shown in your picture.
Any codes with this setup?

Nice wires! I ordered the Taylor wires for my Explorer and I ordered the blue ones, but the jerks sent me black ones
Wish I had blue

I was questioning this also, along with the elbow upstream of MAF
I was In the undersanding the maf should be right after the filter--
But hey, if it works well-it sure looks nice

edit---I can't see your crankcase breather tube-where is it??

I wondered the same thing, but what do I know? Now that gurus like yourself and Jon (jtsmith) are asking, I don't feel so stupid. Whattya know? I'm learning.

To start out with I had located the MAS directly behind the air filter but cosmetically with the parts that I originally used it looked weird so I trimmed the tubes and relocated it where it presently is shown. I would prefer not to have the thing so close to the throttle body, but at the time I did not have a welder capable of rewelding the flange to the aluminum pipe so I have left it where it is. I have experience no ill effects of doing so. As far as having the MAS behind the elbow I am of the opinion that it makes little difference when using high flowing filters and tubes. I think the location of our style MAS are less affected by mounting location than other types such as a vane meter sensor. This location also reduces the risk of oil contamination from the K&N.

hey here in the future im going to be able to get my hands on a 90mm maf+cold air intake and 24 lb injectors (buddy with a stang looking to go carburated) whatcha think is a good price to offer and what kinda gains should i get? if i get it i know i'll get the programmer(sct) and the tm headers and dual cat back.

on my 97 5.0 awd i first went with a mac intake and noticed hardly any difference in performance...maybe a bit but not much.

Then I put on a dynomax ultraflow X muffler with dual 2.5 tailpipes into 4 inch tips. Sounds great and not too loud. Just what I wanted. Low end torque was pretty much the same as stock but I gained top end power.

Then I put on TM headers which give me more torque and power at all rpm ranges. They are pricey but nothing ive done so far gave me the power difference that the headers did.

Ill be getting an xcaliburator 2 as my next and probably final mod and hope to see a bit more difference from it.

I Too free flowing of an exhaust will hurt your lower end when you get the headers.

no such thing as to big of exhaust, the problem is not enough motor...
