intake suggestions?

I haven't got a clue about any of that. One other that only came out on a few thousand cars, was Mopar's Mechanical Fuel Injection on the 1957-1958 Chrysler D300 392 Hemi cars. AWESOME! About 3 MPG more fuel-efficient, but about 18 HP more! From 375 HP to 392 HP.

Wanna see a big car blow the doors of a 'vette, these were the cars (5,500 pound monster, with 900-15 radials just burning the tires off from 30 MPH!)? It was done to improve gas mileage by 50%, too. From 6 to 9 MPG !

 

Sequential EFI, I think.

 

Yeah, that's it. Thanks

 

It's starting to sound like the acronyms and abbreviations in a personal column. PGM-FI, SEFI, sheesh!

Good thing there's no FI-FI.

 

i guess i was unclear, i want to get rid of my airbox all together and get some sort of filter adaptor, i know they make nothing for my car (except the one on the site, thanks) and the filter being restrictive doesn't matter when no air can get to it... soo yeah, my airbox has like 4 tiny holes (see pic of my air box in gallery)

 

I do know what you mean, I am actually going true the same process. The difficulty besides availability (although you could always make something yourself, I find they often charge hundreds of dollars for a piece of pipe, ok, it is shiny), is that the original configuration at least gets fresh air. A lot of aftermarket systems rely on cone filter type things that take air from your engine bay. Not a good thing as you will really loose power. The other thing is that the airbox your standard filter is in is not only a place to put your filter in (duhh), but works as a plenum as well. Replacing it with a pipe often means you will loose low-end torque but gain extra power at higher revs. In mostly normal driving this is not really what you want (especially with a bigger, low rpm engine). Maybe when you rally-style drive your car to work everytime....

Having fresh air has its downside as well as it is involves often open pipes or scoops or low at the ground openings which can be dangerous for water suck up. You really don't want your engine to water-lock when driving true a puddle!!!

One last remark, if you replace your filter box with a pipe and cone filter, you car will make a lot more noise. I when I say a lot more, I mean a lot more!!! I have seen die hard import tuners change intakes for the sake of noise reduction.

I would still go for the standard filter box with aftermarket filter, open it up to a place where it can get enough of fresh air. But you can always experiment with some pipes and a cone filter (shield the intake from warm air if possible). I saw that they even put reflective material around the duct work (gold nasa style stuff) to minimize heat transfer to the breathing air. Looks cool!

In the end it is all down to personal taste and priorities on style and performance. The stock filter box does not really look so good, does it??

Some tuners can bend custom pipes (3" orso) on request, but I guess you can do it at a lot of places. Myself, I going to experiment with some PVC pipe first before spending money on some bends.

 

Let's see if this works for you:

Just checked the Tech Articles on that ThirdGen Page:

There should be something in there for ya!

This guy who's Ram Air page is from a Tufts University Engineering Project has his own site, not well kept anymore, but lots of tech facts. His Project Log Book Page:
http://www.skulte.com/logbook.html

keeps referring to Turbonetics' Air Ratio graphs, and I found that page:

Here's his University Project Page:

That should kickstart you.

With my little six-banger Ford, someday, I may be able to see all GM cars from my Rearview Mirror! I used to in my Hemi cars.

 

And a custom Ram Air on a Jeep TJ. Lots of pics, and the vendors are listed below both sections of this one page tech DIY:

Izzy remove your air box and look real good you should be able to make your own it's not that hard.Measure the Throttlebody inlet and see which way toy can route it you should be able to get most everything you need between the Parts store and/or your local home improvement store.

 

There are 2 main types of fuel injection. The multi port which has an injector at each cylinder and the simple TBI (throttle body injection) which has the injector(s) on top of a carburetor like device. It has throttle plates like a carb, but the fuel squirts from the injectors down the air horn. No floats or needle valves. This system uses much less fuel pressure than MPFI. About 13# compared to about 40#. Still rather have a Holley 4 barrel.

 

Now that's good to know. Thanks.

The Carter AFB's were good too, but Holley's were/are still the winners.

 

You can tune a Holley easier. Racers like them because all you have to do is change the jets instead of messing with metering rods. The old AFBs and AVSs were good, but not so easy to "dial in" as a Holley. I always liked the Thermoquad. If it was right, it ran great, but if it had problems like a leaky bowl, it was a pain. You could adjust the secondary air doors on the QJ to open later, minimizing bog, like changing diaphragm springs on a Holley so equipped. I have never liked the vacuum secondaries. My Holley is a mechanical double pumper.
