Saw this on Pennock's Fiero forum:


I thought it was pretty interesting looking.

MrNova

Isnt that a little like the LS1 intake?

So thats an aftermarket intake for a 2.8 MPFI Fiero right? If it is it would fit onto a 3.1 or 2.8 thirdgen... interesting.

just how many intake ports are on that manifold???

8

Looks like a SBC intake to me. 8 intake ports, siamesed intake ports, distributor mounting, water outlets, etc.

I assume those bright metal inlets are actually individual TBs? The only thing i don't see is injectors, i guess they're hidden under the runners.

Anyhow, it's neat looking, but i bet idle control is a pain. unless it has some kind of common IAC passages.

No, that's for a V8...

It's definitely fabbed, though. Not some "new" production manifold. Looks pretty good from what little there is to look at. I'd like to see how the fuel system is set up..

There's just something cool about seeing four butterflies opening at the same time whether or not it's worth anything power-wise.

Where's the rest of it?

Oh, I see.. hmm.. neat, I guess.

Unless there were two of them, that particular intake was fabricated in Lingenfelter's shop. It was for sale on eBay a few months ago.

and just for the record, I knew it was for a V8, thats why I put 8 after i made my last reply lol

Yes it is, in fact its basically the same idea except with individual throttle bodies. This thing should work wonders on an L98.

D Stroy H8

Whoops! Yeah there are obviously eight ports there... I'm a dumbass who doesn't make basic observations

Not at all. The LS1 intake is so nice because of it's very well designed intake runner length and port. The LS1 intake has a lot better tolerances and mounts with the LS1's heads without a gasket disrupting air flow (except for a o ring seal, but this does not disrupt air flow) this makes the air travel into the heads with less turbulence and resistance. Also the LS1 intake is made out of plastic to keep incoming air cooler.

this intake is nothing like a LS1 intake.

Take it easy chief, no one said it was an LS1 intake. But it's undeniable the idea behind the LS1's intermediate runner lengths (as oppoesed to the TPI Long setup and the LT1 short setup) to get the best of both worlds is at work here. It even looks modeled after the LS1 design rather modeled after the HSR or such.

The LS1 shares a central plenum,
and this looks nothing like an LS1 intake to me.

Think outside the box here for a sceond. Read what MrNova asked again

"Isnt that a little like the LS1 intake?"

And here's what I said in reply.

"Yes it is, in fact its basically the same idea..."

Maybe it doesn't look it to you but it looks more like an LS1 than anytihng else. But regardelss the fact remains that the idea (or one of the ideas) behind the LS1 intake was to have shorter runner lengths than an LTR setup for more hp yet not so short as the LT1 to provide for better tq. This idea is also obviously at work here in this intake. You can say all you want about its not being plastic or using individual runners instead of a plenum but the same idea remains.

MrNova

I just meant the runners had that pretty criss crossy design, if only they were shinny.

It looks like (in principle) a Hilborn...that was "laid on it's side".

Looks like the Fuel Rail(s) runs right down the center of the intake.

I think those four wire looms looking things are the fuel injector power wires.

RCR

From what I understand, it is from Lingenfelter, and there are three of them. This guy has all three.

I have no idea where the injectors go, and when I look at it, I think of the TPI base with a throttle body mounted to each opening. Pretty slick, I suppose it would run like an LT1 or HSR

Wow, that thing would look so killer powder coated red under the hood of my car!! I was looking at it and I think it would really be a pain to get setup right though. I guess Mr. Lingenfelter really does get creative. Taking LS-1 technology and bonding it to a TPI base. Right on.

89 Iroc Z

I just want to clear this up, this is not LS1 technology.

RCR

I don't know the age, but my guess is that it pre-dates the LS1 release.

You never know, maybe this piece is the forefather of the LS1 style intake.
