We recieved the sample mandril Sat and it looks good. Be placing an order today. So in something like four weeks, we should be ready to knock-off the finial protype and start making them. They're going to be so awsume (functionally and looks-wise) I wish we could post a pic.

We'll put one on my 2.8 turbo first, use on the street a bit and then take it to the dyno the same day we go with you. Once we get the finial prototype done, we'll come up with a date for you to drive out. We may also have another fellow (I think he's in Maryland) do one too. For now, we're back in a holding pattern waiting for the mandrils, which in a way is ok with me, since I'm still not 100% yet.

If I find the guy with the stock 2.8, then I guess you can bring your 3.4. But also, since we're putting one on my 2.8 anyway, and I can do runs with the turbo open and with it working, I suppose you can bring whichever you prefer. I'd really like see what it'll do for the 3.4 since the stock manifold has be putting an even bigger hurt on that engine. So which would you rather do? BTW: we recieved all of the main flanges yesterday, just need those custom mandrils now.

I think you should bring your 3.4 also. I know I'm (and a few others) counting on this intake to bring out the full potential of this larger displacement engine. Thanks again Francis I look foreward to the pics and some good numbers. Jason

Definately bring the 3.4. I plan to put mine on a ported lower plenum and stick a ported throttle body on it, then stick all that on my 3.4. I think it will make a significant difference.

well, ive got two fiero's with the 3.4L, but ill probably be bringing my white 87GT 3.4L, custom 2.5" exhaust from the Y of the y-pipe down, ported stock exhaust manifolds, and bored plenum and throttlebody, lastly 19# mustang injectors, other than those items its bone stock, i have not ported the middle or lower manifolds at all, and the car starts bogging down at 4800 RPM or so needing more air, a custom chip would do my car wonders also, it just doesnt feel like its running right to me.

Hold off on buying that chip for now Matt. I replaced my stock one with a Hypertec and it didn't help much for the money. It leanded the mix some to compensate for the lack of air at higher rpm. Since we put the turbo on my 2.8 Troy burned a chip to match things up better. In your case, with the better flow from our new manifold, the stock chip may be better than an aftermarket one. If not, and we're in no way going to do this for others, but because of your support with the project (free engine etc), I think Troy will burn a custom chip for you. With the dyno printouts he'll know just what to do. I love the setup he did for me.

Without doing dyno/wideband, you can't really 'order' that good of a custom chip. And we will use a wideband. The runs we made on my 2.8 were done with a wideband, thus we have some good data to compare the new manifold with.

What kind of chip editing capabilities do you have? Obviously, recording the changes from a stock program that will be necessary to run your intake on a stock engine will give you a big head start in being able to tune the intake on a modified engine because you'll have excellent data on how it affects VE curve relative to stock...

We have a burner and program and can change most any paramitor, but we're not going to offer that service. It's too big of a P.I.A, since people like to keep changing things on their engines and then complain that the chip is NG. Besides, you really have to put a car on a dyno with a wideband to do it right. I think the setup we brought to do our own chips cost something like $300, but I could be wrong. That's not too big an investment, but you best know what you're doing before you start to play around with chips. My son Troy does engine amagment systems and knows his stuff, I'm still in the dark about a lot of it. When all is said and done with the manifolds, he may make suggestions, but I know he doesn't want to get into that area.

Like I said a few post back, we ordered the custom mandrils and they could take another few weeks. After which, we'll work-up the finial prototype and post some pictures etc. Hang in there, they're comming.

Put me down as a potential buyer. I would hope it would wake up my highly modified 3.4. What would really be nice if you'ld make one to fit gen 3 heads, just a thought. I've been following this since it started and desided to add my 2 cents. Keep up the good work. Waiting patiently

Optimal runner dia for a fiero head is 1.54, yours is 1.375 A combined runner length of 13" including the head is about 2 to 4 inches to short for a 3.4 depending on tune. In my case, turning 6000rpm with a 272 cam the perfect length would be 14"......add some length as you detune and come down in rpm.
So if im building a 7500rpm large cam 3.4 that runner length would work. But the runners are too narrow and would negate any positive gains from the length tuning.
Tell me what you think.
I didnt even bother testing the numbers for the plenum.

Sorry for no updates as of late, been out of the country a few weeks. No pics, because we're still waiting for the custom mandrils, As for the last question: Optium runner size & lenght is depandant on a lot of factors and nice talk about and maybe even put a priority on if you're 'only planning' to build one on paper. As for making a real one, the larger dia mandrils would require larger bends and that would make the manifolds higher, so much so, that everyone would have to cut huge holes in the top of their engine lids and put a scoop or something over it. I don't think that would go over too well with most people. One of reasons it takes so long to design and build such things, (unless you have the computer systems and programs like GM) is that what looks great on paper (or you simple CAD program) does not always work when applied to the real thing. Don't worry, you'll like it a lot when you see it.

I got a call from the place I am buying the mandrels and they said they were getting shipped the beginning of this week. They are coming truck freight to me from west coast Canada to me. I was hoping to get them this week but they have not come in yet. I am pretty sure I will get them next week and once they are done I will let you know.
Donk316. Once I get the intake prototype done I will post all information. I will try to make the length as long as possible to within space constraints. You cannot just say lets make it this size and that long because of major space restraints. Well, I could but the trunk would not close. When you see what it looks like when done you will see what I am talking about. I do welcome your comments and opinions as this subject. If you want to email me at Troymx576@aol.com and I can discuss if further if you want about specifics. When I ordered the piping it is actually much longer in length so I will make it as long within what I can. I will also get more specifics on the lengths and diameters when the final prototype is done.
PS: The time the vendors are taking is killing me much more than it is killing any of you.
Originally posted by Skybax: I did read this entire thread... but that was months ago. Basic question..... how benificial do you think this intake would be on a stock 2.8 with stock PROM ID?
the whole key to opened intake is opened exhaust also. but, even with stock/unported exhaust manifolds, I do believe it will really help (2-5HP) a stock 2.8 with stock ECM in the 4500+ rpm area. but, with a cam & headers, yeehaw! 2-5 HP doesnt sound like a whole lot, but its also a longer power curve, so you can make a little more power a little longer, moving up the shift point
