MAF & air intake questions

[Zandoz]

I'm building a T bucket/modified/track-roadster around an 89' Camaro 2.8 60V6. The plan is for the upper manifold & throttle body to be exposed, as opposed to being under a hood. My engine came with nothing beyond the throttle body. I know there is supposed to be MAF tube/sensor "out there", and from the pics I've seen it's ugly, and mounts on the end of a rather ugly flex tube. Ideally I'd like to just mount a K&N style filter right on the front of the throttle body. I've seen pics of cold air kits for Fiero 2.8s that appear to have no provision for a MAF. How necessary is the MAF sensor? A search brought up a post on a Camaro forum about swapping a working MAF tube with a gutted one...but gave no reason or results. Is possible to relocate it, and some how trick the ECM to thinking it is where it would normally be? Could it be mounted directly to the mouth of the throttle body, with a filter attached directly to it? Does anyone have the dimensions of the MAF tube?

Some F body ECMs use a MAF, some don't, you could use a '7730 ECM, and the would only require a MAP sensor.

How do I tell what ECM I have? How/where is a MAP sensor located? Would a MAP would be less obtrusive than the MAF set up?

a Map sensor measures engine vacuum, and looks like this

as far as the ECM goes, you should have the older MAF style. IIRC only 90-92 got the '7730

Do you know there is a nice intake made to mount a 4bbl Carb to that engine? Larry

please don't do a 4bbl! please! you're already doing something cool and unique, don't ruin it with a boring old 4bbl!

Yea, I know there are carb options, but I'd hoped to stick to the MPFI set up I have. I'm on a seriously tight budget (retired on disability), and as long as keeping the MPFI is financially feasible, that's what I'll do. If I do end up going the carb route I'd probably go with a Weber progressive 2bbl set up...a 4bbl seems to me to be overkill on an other wise near stock 2.8. The only mods I'm anticipating until I know how this thing runs as-is, are a set of lake style headers, a bit hotter coil with good plugs and wires, and what ever I figure out for the air intake. For a casual cruiser that is only going to be in the 1200-1500 lb weight range, I'm hoping I do not need much more.

If anyone is wondering, these are excellent examples of what I'm shooting for with my project........

there's another guy on here building one, 23trackroadsterV6 is his login.

here's one of his threads.

Lets see................A 1930's or 40's roadster with a fuel injected engine, what is wrong with this picture? Larry

[ericjon262]

nothing wrong with it, build something different and enjoy it. and I didn't say injected specifically, I just said no 4bbl.

Nothing more than the multitude out there running LS V8s...or alloy wheels...or super/turbo chargers...or disk brakes...or stereos...or tilt steering columns............not too many 4bbl carbs back then.

The ones pictured have modern Ford 2.3 SOHC 4s...and are 1920s bodies...1926/27 Model T to be specific. The same that I'm hoping to use with mine.

The beauty of building a hot rod is that you can build it any way you want and can afford.

[ericjon262]

do you have a build thread anywhere?

Not at this point. Right now i'm in the planning and acquisition phase. I want to get the major components on hand before I start frame construction. Right now it's all in my head, and a CAD file...both change several times a day...LOL. When I do get to the point of more than a pile of parts, I'll post something here.

[ericjon262]

keep us updated, I like seeing unique and different builds.
