I found someone who has been building custom EFI intakes for all types of vehicles, including 2.8 Fieros (similar, but different to our F-body intakes). I'm sending him a stock intake along with measurements (hood clearance etc) , and hopefully soon there will be an F-body replacement intake available. It will use the stock base, fuel rails, etc, and they will be available to fit non stock throttle bodies. I have no financial interest in this at all...I just would like to see more parts available for the 60 degree V6s. If there is any interest, please post!

 

Hmmm. Interesting looking intake. Do you have any more pictures? Perhaps larger pictures?

Sorry, some of these are too big to post...here's another vieew, but small

 

if they are on a site, you can hyperlink to them.

If nothing else, can you PM me so you can email them to me?


I see for me I would have to change the front TB mount, and possibly neck.

 

wow, that looks awesome, can you send me the pictures too? AdmAnt13@optonline.net

Any idea when this might be available?

 

look at the **** on that one!

i hope any of these intakes become available

 

Whoa that looks COOL! Put that and the pacesetters together...

 

I like the smooth wide arching bends. I wish the plenum was larger though and the runners just a tad shorter. I think to fit under our hoods, the arched runners should begin paralell to the hood line and then arch downward instead up the up and then down "heart shape" the both sides together make.

I am still very curious whether shorter runners like the unit I made or longer runners like this unit would work any better than the other. I am open to anything that works best and will buy one if results proove so.

 

That looks alot like what I plan on building myself (except I was going to go twin plenum)... might just have to save myself the trouble. I like the runner length just the way it is, personally.

 

The intake pictured is the Fiero version...it faces the opposite direction on the base (same base) from our cars, and the neck is much longer. The F-body version will have a much shorter neck. There are two different runner length versions for the Fiero; not sure if this will be practical for the F-body, but who knows. I'm shipping an intake to him this week, so hopefully I'll know something for sure soon.

 

that lookas about a thousand times more efficient then the piece of junk stock unit the factory put on there. .... course the average person would'nt care.... but we true "3rd genners" hold ourselves to a higher standard.

 

it reminds of kinda of the tpi intake for the v8. not really but kinda


I would really like to see the results from this myself. I know when loking under the hood of my friends firebird that stock intake looked like a joke.
nice tight bends crappy looking plenum all in all just not the greatest looking piece




I need to learn how to weld guys I really do

 

I just rented a Chrysler 300 Touring for the weekend and returned it already. It had a 3.5L V6 that puts out about 250hp.

I popped the hood to check out the motor (should have taken a picture) and the composite intake manifold has dual routings after the TB to two separate plenums that feed the same base intake manifold.

Each plenum has motor servos that open and close them. One plenum sits directly above the base manifold with very short runners and the other side over the passengerside valvecover and has loger runners angled diretly across and arching into the middle of the shorter runners.

There is a very noticiable powerband boost when this motor reached 3000 rpms and pulled very strongly right up to the 6500 prm redline (ps- rental agent:"Did you want our bumper to bumper insurance?" Myself: "Yes I do" I beat the livin crap out of it.

I'll have to find a picture of the plenum online somewhere

 

get it a CARB # and youll have my money.

damn CARB

 

Agreed

 

I think the guys set up is reminiscent of the early Chrysler long tube dual quad ram intakes. Like 1960-61 engines of the 413 size.
Those long tubes apparently great for more torque.
I think this guy is onto something as long as the choosen tubes do not degenrate over a period of time from gas/fuel/any other matter present in an engine.
The current MPFI set up ain't so bad. I mean it does adapt to 3.4 usage quite well!
And CARB ain't so bad. What CARB approval also gains us hot rodders is a better quality product for purchasing that "withstands" long term usage without breaking.
AND I definetly enjoy my 4 year old growing up in better cleaner air than when I first moved to SoCal back in 1980/81. Damn, I heard that the 1970's air quality was even worse than when I saw the air back then.
I'm happy to support the work of CARB.
This product is something to keep us posted on the development.

 

I finally got the original intake out yesterday, so hopefully we'll have it available soon. It shouldn't take much changing to the Fiero design to make it work on our cars. Hopefully, we'll have some pics of it on the car and some dyno #s soon!

 

Looks pretty cool, almost looks like a marine application intake. I wish there were some numbers on its performance.

 

There will be soon...the Fiero numbers were very good, so we're thinking the F-body version will do at least as well.

 

you ever gonna get that bad boy to my shop se we can tune her for ya ? just get nice new dyno!!! mustang 1750de !

 

what are those two hose barbs for? is that for the TB coolent lines?

 

those are for vacuum lines hookups. they would most likely be on the back on any f-body version; they should be, anyways.

 

Id use it.

 

NOW that is the intake I have been asking for , for years.
Thats its. A nice round fart can long tube intake.

He already sold 1 to me. I'll buy that last year.

ohh and screw and changes, just slap the TB on the other side and mod the hood guys. I want that one, right there. That will look super **** sticking out of my hood. Not to mention all the extra cooling.

 

Sort of imagine the hood line n window.

 

We agree on something. Go figure.

 

Will this clear the hood?

 

no, it will not clear the hood. if you had a camaro i can think of no better purpose for a shaker. oh, ... except perhaps a supercharger. yeah that might be better.

 

*laughes* Xopher, you got it

So I guess that leaves me as the only one not liking that plenum in the least?

 

The runners will likely have to be shorter to clear the hood...as I said, the F-body version is still in the planning stages. Soon though, hopefully! I'll post pics as soon as I get them.

BTW Doward, just curious...what don't you like about it?

 

What the... I had edited the post with all the reasons!! What happened?

In a nutshell, the runners seem to large in comparision to -

a) the intake runner of the head itself, causing a severe loss of velocity
b) the plenum is entirely too small in comparison to the motor, and runners.

I like to see runner volume = single cylinder volume (tune the length/cross section as to where you want peak VE) and the plenum volume = 1.5-2.0x the total displacement of the motor.

The McKinney manifold is much closer than this, IMHO, but not quite there. I do, on the other hand, REALLY like Dean's plenum! As a matter of fact, I've already spoken with him.. The plenum I'm designing is very close to his, only not *quite* so much plenum volume.

Now, don't get me wrong - I do like the way it looks! And it is definetely better than stock... only in my opinion, it's much like the turbo kit that was posted in these forums, it looks good, but could use a little more engineering

This is just my OPINION on it!

 

I might be restating what you (Doward) said as "a." But, the runners are the same diameter all the way down, that does not help velocity. Then the big killer of the velocity on this design... it appears as though the bottom of the runners are actually flared to match up to the base. That will cause the air to slow down, drastically.

 

However it does, we'll post the dyno results, before and after, and if it doesn't do as well as we hoped, we'll try AM91's intake. I just think its great that more parts are becoming avialable for these engines. When I first started frequenting the V6 forum, there were no intakes, no headers, no turbo kits, no serious V6 performance buildups...very little beyond good tuneups and engine swaps (very helpful, but you see my point).

 

Yes, I definately agree! Its great to see more stuff coming available for these engines!

 

BTW, does someone have a link to Dean's site? I had it bookmarked and lost it. Thanks!

 

deans is a car-domain site.

Try searching under vsixtoy, agood2.8, and his new name, "rftc"

Well who is the guy LT1. As I don't want some new design. I want that one in the pic.

Others:

Do you really think every intake or exhaust made on them custom bikes show gives the bike better performance??? Performance is never part of the equation. Its all about looks.
I really dig the looks and as long as it works as well as stock. fine. Doward seams to be able to force plenty of air into his.

As of right now. I like the looks the best.
Long as the intake doesn't hurt performance over stock.....

I was going to wait until we had a prototype, but here you go.
