I understand that from the picture. I guess what I'm asking is if you have a fuel feed system designed to mate with the intake? Or would a buyer need to fabricate one for himself?
Having made my own open plenum intake for a turbo engine I found that one of the most difficult aspects with the 60* engine is the limited space available between the heads to place injectors and the associated fuel supply rails. Just wondering if you had already worked out the details.
EDIT: those welds look beautiful. I wish I could weld half that well.

I understand your concern and that is why I went a different route as far as the fuel supply. Service and replacement of injectors will be a breeze. It will also give you the liberty of using the fuel pressure regulator ir FMU of your choice. Injector location was the other area that was carefully chosen for best performance.
As far as the welds, they are not mine! I just put the idea on paper and my fabricator does the rest. But thank you, I will let him know that.

I see you're finally ditching the stock middle intake and its "soda straw" intake ports. That should boost the upper end performance considerably.
Yes Blacktree, it was time to innovate something better. Although the current intake I have installed on the engine doesn't have those runners either and as you mentioned it boosted the power in the upper RPM range.
One of the big name brand companys is using the name " super ram" You might have to add some thing to the name. But finaly, some body has made a "no holds barred" intake for it.
Looked at the picture and I have one question: where are the screw bosses to mount a plenum? Or do you still need to weld on a plate at the top that will have holes for fastening a plenum?

No bolt-on plenum. It'll be one piece intake. About the name I just noticed that the name super ram is taken. I think I'd re-name it FunnelRam because that is the principle behind the design.
Interesting... so how much have you gained just from tweaking the intake? I'm taking it on assumption this is also from tuning?
This intake I haven't finished yet. There have been 3 previous intake designs but this latest one will be the best so far. The intakes by themselves will not give you much. I dynoed the 1st intake swap only and it only gave me 3whp and 2lbs/ft of torque at the wheel. Everything is about combination. After I combined the intake with the right head, camshaft exhaust and a better tuning I gained 88whp at 6100rpm. This intake is part of a package for my non roller 3.4, Every item of the package is one of a kind.
Nice, I wasn't sure if the heads had been ported, etc. If you've seen that much of a gain with an intake that started as a stock 2.8 unit, it makes me wonder what the 3900 is capable of in modified form.
On the next one, radius these runners at the plenum as much as possible. I was messing around with this on a flow bench, and you wouldn't believe the difference it makes.

That's something I learned the hard way. My ported and shortened stock intake w57mm TB combination made more power than my Trueleo + twin 48mm TB combination with the stock 3400 cam on my ported iron heads. I need a bigger cam to induce more vacuum from the intake to take advantage of the Trueleo...hence I'm switching back to the ported Fiero intake but adding the DAWG mod until my next motor build that will have a high lift cam and the Trueleo setup.
187 rwhp @ 4150 RPM and 249 ft*lbs @ 3600 RPM (ported and shortened Fiero upper and middle intake with 57mm TB) vs. 166 rwhp @ 4900 rpm and 203 ft*lbs @ 4000 rpm (Trueleo intake w/twin 48mm TB from L98 V8)
Both used the same ported and polished lower intake with ported heads, intake ports on the heads left rough, polished exhaust ports with 1 3/16" openings feeding Trueleo headers and a full 2.5" exhaust. Both dynos were done on the SAME MUSTANG dyno. On a dynojet, I've done 10rwhp and torque higher on the Trueleo setup and never took the old setup to a Dynojet. I'm hoping the DAWG mod will allow the stock intake to peak higher than 4150 rpm while still maintaining my torque over a wider power band. My goal is to break 200rwhp with the stock 3400 cam ... because iron heads DO FLOW when ported.
Lesson: if a 3.4/3400 only pulls 400cfm @ 100% VE or 360cfm @ 90% or 340cfm @ 85%, there is no need to build an intake that flows 500cfm.

Also as far at the design, I have seen a few similar designs where the Plenum was assembled more like a mail box and instead of a standard thickness sheet of aluminum for the piece where the air enters the runners they use a 3/4 or 1" plate and that becomes a very easy to port last 1" or so of the top of the runners then the top of the plenum can be welded on after all the runners are radiused. I'll try to find a pic. Bacialy you can eliminate all the welds on the inside of the plenum @ the runners inlet

When mated to a good intake, yes indeed the stock heads flow. Was that 400 cfm number with a stick intake; it sounds bit high for a stock intake?

Ehhhh, I still have my Fiero. Just doing some kart racing but the Fiero is my baby. Big valve head are just finished and on their way and this intake is going on them!
may want to redesign the entry of those ports, those sharp square edges aren't helping, probably reducing the entry by 20% or so. Would be my educated(or lack thereof)guess.
