Just to let everyone know, we awarded an order for the first 25 flanges for our 2,8 hi-flo intake manifold and should start work the first prototype real soon. If you're not on our list of 'may want to buy one' let me know.

Ill need ALOT more info before I sign up. Whats it replace? Just the plenum? What does it flow? What TB does it use? Is it dual TB? How big is the plenum? Runner Length? Runner cross section? Equal length runners bank to bank or unequal? Whats the manifold tuned for RPM -wise? Factory fuel rail? Provisions for NOS plumbing? Any info would be cool!

*ALL THROTTLE AND NO BOTTLE*

First off, we're not obligating anyone to buy the thing, just trying to get an idea on how many people would want them. When the prototype is done, we're going to do a dyno run with stock 2.8 manifold (already have someone waiting to use his car as the test mule) and then do some runs with the hi-flo. We will use a wide-band too to get a good picture of what's happening. We are not looking to make it for high rpm only, if you're worried about that. And it will replace BOTH the upper and lower units.

Hey thanks for the link to your site. I see what you have done but still have many questions. The same ones I have above. How did you decide plenum size and runner sizing? I would love an all out rpm intake thats why I have resorted to building my own also. Would love as much technical info as your willing to share

I think a lot of 3.4 people will get in on this one. I know I'd like to. Hopefully you will still be making them in a few months when I'm not in debt. When people swap in the Camaro 3.4 pushrod motor, we use the Fiero intakes because the Camaro one won't fit. But the 3.4 needs more air than the 2.8, and the Fiero intakes are restrictive for the 2.8, so you can imagine the problem they cause on a 3.4. I'll bet you definately see a few more ponies on the dyno on a 3.4 with a much better flowing intake system. Jstricker already tried increasing the plenum volume and decreasing the length of the runners, but minimal gain came from it. However, he was machining a stock upper plenum. A whole new system I think would do wonders.

What are you making the flanges out of?

Want to sell a pair? If so, how much?

thats why i volunteer'd my car has test mule, we will be testing it on my 85GT 2.8L automatic i suppose, only mod it has is a set of ported exhaust manifolds, otherwise its a bone stock motor (but getting code 32 for some reason)

If frank would rather test it on my 87GT i can bring it also, its a 3.4L pushrod motor, 19lb injectors, ported exhaust, bored out intake plenum and throttle body, custom exhaust with 2.5" pipes running back to a flowmaster muffler.

Question 1: as for the specs, my son is the tuner guru and he will list the specs when he's done. At the SCC ultimate street car compitition he had the highest HP per CC and that was with his mix set a little too lean (it was hotter in Ca than Virginia) and a knock. he knows his stuff.
2: our flanges are being laser cut from 3/8" steel. I'll ask my son if he wants to let one go.
3: Matt, since more people are running the 2.8 I think we should that engine first, but if you want to bring both, talk to my son. It would be nice to evaluate 2 engines on the same day. BTY, we'll also see what it does for my 2.8 turbo, and boy am I loving all that new HP. Spools up in a heartbeat too! YEs, pics soon

You can count me as interested.

You already know of my interest, but I'll comment again, here.
Fastback 86 pretty much nailed it. As beneficial as this will be for the 2.8 guys, the 3.4 engines are the ones that are in need of a "breath of fresh air".

So it was his Mr2 in the USCC!!

That thing is sick! I was pulling for him, I figured that since a fiero can't seem to make it's way onto
the USCC, the closest thing would be a MR2. Plus, I have alot more respect for people that actually
build the stuff that goes into their cars, instead of just walking into a tuner shop, handing the guy behind the counter
a blank check and telling them," I want two of everything, let me know when it's done"

So, any thoughts on a crankshaft main girdle for
a 60 degree v6??

That would help alot on the durability of the engine under high power apps.

I'm pretty sure I was on the list of your previous post, if not consider me very interested! (I'm also installing a 3.4) Jason

Francis T - Your comment about not getting rich by making the new manifolds is much too kind. Just like Rodney Dickman and The Fiero Store, if you make something good available to us, that we need and no one else has available, you deserve to get rich.
Some of the guys complain about Rodneys prices or the Fiero Store, but they have stuff available that saves us time and all kinds of labor. I just bought Rodneys stainless steel vacuum lines for $ 100. Try finding a custom set anywhere else. Or vacuum lines that assure you that for the rest of your life, you will not have a vacuum line problem. For that kind of product, $ 100 is a bargain. You're doing us all a favor by trying to produce a good product, you deserve a decent return for your efforts. Ed

I would also be very interested

I highly doubt that either Rodney or the Fiero store are getting rich off of the Fiero market.

I'd love to be wrong, though, because if they're getting rich they'll probably be around for a while.

I'd be interested in a set when I finally get a 3.4 into my '86. Not sure when that'll be tho.

Thanks for response everyone. BTY, that was my son's car in the compitation and to say he was bummed-out to have blown a head gasket that way, don't even come close. He was supposed to have two other drivers with him on his way to Ca from Va but both were too scared of the winds they encountered and thus he had to drive the whole way. On dyno day he was so tired, he forgot to adjust for the hotter LA weather and it went lean with 29lbs of boast! I'm still very prod of what he (with a little help from me) built. He engineered that car from top to bottom himself. I've been in lots of fast cars 250 v12 Farrirs, 427 vets, Mopars etc, and none of them can hold a candle to that MR2 of his. And the sound of 11,000 screaming rpm.... Anyway he has my little 2.8 turbo running hard now too, but not like that MR2. I best be quiet now, us dads can run on and on about our sons.

As you folks chime-in on wanting the manifold, I've been adding you to the list. We have about tweenty people so far. When we're ready for the first production run (after testing etc) we'll post pics, specs, dyno charts etc and take orders. Those on the list will get first crack at ordering. We ordered enough flanges for 25 units, so even with the prototypes, we'll be able to fill like 21 or 22 orders with that first batch, and that will be to those on the list in thanks for responding early. BTY, a few of you only gave your PFF handle and I listed that way, if you can, give me your e-mail too. Thanks everyone. Still waiting for the flanges to get here. When you see how complcated they are, you'll understand why we had them laser cut.

Something that I'm not clear about.

The MR2 manifold (It's a beautiful piece, by the way) feeds one bank of four cylinders, where the V-6 manifold has to feed two banks of three.
Does your manifold replace all three sections of the Fiero manifold, right down to the heads? Does it replace all but the base?
If it replaces "everything", it will have to include the valley cover and all the coolant passages and stuff. Right?
I'm just trying to picture it. Sounds like it's going to be a very complicated piece.

Please don't mistake my curiosity for cynicism. I've dreamed about a "good" manifold for a long time, even to the point of looking for metal stock to have a custom plenum fabricated. Just trying to picture it, is all.

Raydar, as of prototype # 1 we are going to use the valley cover (I.E. the bottom unit with the injectors) and replace both the top and middle units. All 6 runners will feed into one plenium, and you will be able to use the OEM fuel rail. We drafted up some plans for a 'direct to the heads' manifold with a really neat setup for the injectors, but we decided it would be a bit costly for most users. The thing is, if you make the manifold too costly, most people will ellect to use forced induction, if it's only going to cost a little more. However, if we don't get the big gains in flow that we expect (and we're still quite confident) from what were are going to build, we may build the more complicated design. If you look closely at the MR2 unit, you'll see that we went from the rectangle head ports to round runners and that's what we'll be doing for the fiero (though a little more complicated to achive) and why we had to have laser-cut flanges made, and I wish they'ed get here. Nuts, no UPS monday either, I'll keep ya posted.

Very cool. The lower plenum doesn't really appear to be that big of a problem. The intakes into the heads open up much more. The upper and middle plenums are the real restriction. That was my take on it when I had my engine apart.

The only real restriction after you port the lower is the upper plenum....save yourself the hassle and build a better plenum

Okay. That makes sense. That bottom casting would be a real biatch to reproduce with tubing and flat steel.

I understand the bottom intake (the part you are retaining) can be ported out quite a bit. Darrell Morse has done several of them, as have some others.
I don't have flow numbers, but I'm sure that many people here can supply educated guesses, if not exact measurements.

We'll be here...

[This message has been edited by Raydar (edited 05-30-2004).]

we thought about porting the lower unit, however that would require everyone sending us their valley (lowest manifold) covers and also add to the cost. We think the gains with just the 2 new upper units will be enough to negate the need for porting the lower unit too. For you guys looking for every last smeggen of power, you could of cause port the valley cover yourself or send it out. Considering that youll be able order our manifolds (at extra cost) setup for larger TBs, I think most will be happy without porting the valley cover.

Count me in for one. If you can solve the huge problem of low intake flow I would bet that you will have quite a few orders. Don't forget the equally huge cavalier Z24 market out there as well as any of the millions of GM cars that used the 2.8. Thanks for your dedication to improving the performance of the Fiero.

bump, anymore updates or how bout pics!

See above quote.

No we haven't forgot you flokes, we're still waiting for the initial order of flanges to get here. Should be any day now.

WOHOO! I personally can't wait!!

So I'm guessing your custom manifold is going to be like a header for the intake? I'm just trying to picture it.

Go to trueleo.com and take a look at the manifolds we make for MR2s, it will be something like that, kinda.

OOOOOO, im excited, Hopefully ill still have my stock 2.8L in my 85GT then

right now i have a 3.4L ready to go for it, but ive been holding off

How much would you and your son charge me for forced induction on my 3.4L? (shoot me an email with the price, or a PM) if you would even do such a thing

Your best bet would be to use the 3.4 block from a Camero or Firebird, they have a improved oiling system and wider main caps. With these improvements as well as a few others not, the 3.4 can hold higher RPM's ( from a local speed shop that built a few including mine, they say the stock block can pull 8,000 RPM for a good period of time ) and the heads will not be starved of oil unless hard decelleration is experianced. To me the 2.8 needs too many add ons and modifications to even come close to a stock 3.4, but that is only my opinion from research that I have come up with, you should look into both before making any decisions, but I am confident you would go with the 3.4 when you are done looking at the changes and improvments made over the 2.8.

any news frank?
