As far as I'm aware, that's the only prototype which like yours, was modeled for a stroker. The results of this strocker intake on a 5 liter is very encouraging......wink wink....
I think you and Greg should bang heads together and get something figured out for the 5 liters.
Actually it cost neither Jim nor I anything other that time, Greg didn't think it was ready for prime time, and for the hours he had in it, he would have lost money selling it for $10K, so he didn't sell it. Each of the runners was a different shape, each inlet on the plenum was at a different angle, total nightmare to build. It was a full time job for one of Greg's guys, for large chunks of 2013.

According to the dyno's, Greg's intake was better suited for a 5.0 vs a 6.xx stroker. That is no slam at all because picking up those kind of numbers on a stock-ish 5.0 is beyond expectations, IMO at least.

I'm going to make a cant-roof version of our 654 intake manifold next. It will be lower at the front than at the back, so that the whole thing will fit under a stock 928 hood.
Compared to the Hi-Rise 654 manifold, the intake runner lengths will vary in length front-to-back so the power curve will be even broader, although the peak HP may not be quite as high. That will be better for street driving.

Mark, I have been watching your project with interest, mainly to see just how you were going to fab the tubes to match between the main pieces. My own project has kind of been on hold for a while for a couple of reasons: one is that I have based my fabrication base plate on the footprint of an existing S4 manifold, but I am not confident about how well that actually matches the headson an assembled engine. I think some of what you have shown in this thread is that they don't match very well. Because of that I have made a couple of attempts to have Obehave2.0 respond about selling me one of the fabrication base plates that you got from him, but he has not responded.
So, I wonder, if you really are going to abandon your project, are you perhaps willing to sell me the base plate you have? I hate to be gleaning like this if there is any chance you might get back to your project, but the plate will certainly help me out so I can get to the welding that I have been holding off on.
Hi jerry, sure, i have realized that this is way too much for me with my tools and resourses yes, i see great promise with an intake made from other manufactures adapted to the 928, but the runner adaptation is too much to work with. i bet Greg or someone could make it work, but i cant. no way.
so, PM me and i will get this base plate off to you . keep it around, in case in the next few years i get real good at tig welding. (starting to learn now)

Thanks, Mark. I'll send a PM. I too thought that it could very well come back to you at some point since I think I will need it only for this one-off I am working on. Shipping address in my avatar.
Is no one surprised how almost perfect the 944S2 ports are to the S4? this is about 5mins with a dremmel to make the adapters fit perfect! is there going to be a run on 944 intakes? looks like they are alll over ebay at $150 shipped.
QUOTE=mark kibort;14662937]Here is what i have left. interesting
to note , the 944 adapters look very close to what was made custom for this purpose.
the stubs or adapters
the runners from the 944S2 intake
and the Amv8 intake with its legs cut off. [/QUOTE]
Er, no. The 944S2 head and the 928 S4 head are very similar.
Er YEAH, few posts showing it was off by 6 mm,........ the ports look VERY close. so , i was happy to see that. sure makes the adapter issue, a non -issue, unless the aluminum is hard to weld or the missing bolt hole is a problem. i wonder if there is a different S2 intake...maybe the turbo version is bigger? 6mm is HUGE difference.
both Strosek and VRocket thought that there was a 6mm difference in width. VRocket had a picture of a 944S2 manifold on the S3 928 head, but that is not the S4 head. Strosek said he verfied by measuring... what am i missing here. why such a difference? you can see the pics. not much difference at all. 2mm on the center engine side. almost a perfect fit. https://rennlist.com/forums/928-foru...l#post14646350 https://rennlist.com/forums/928-foru...l#post14646730
Well, it is official. ive sold off the 944S2 intake cuff off -S4 intake adapter, and the mounting orienting plate and if anyone is interested in the AMV8 intake, im selling that too.
I still think its a great idea with a welll designed intake, that only needs some tubes attached at the legs... based on what ive seen here from Greg carl and so many others, i would think it would be easy to adapt some small tube sections , curved on the ends, to make this intake work on the 928. seems MUCH easier than an entire design. as you can see , my thought of an angled tube connection would not be ideal, but if someone could make an "S" curved tube to connect the intake to the base, it would be a slam dunk. just at TB, the MAF, bolt the stock fuel rails to it,with idle stabilization system and you would have some big bolt on HP over stock. 5 liter or 6.5 liter.
anyway, ill focus on racing the car this year, and you guys figure out how to make some easy power!

If it's so easy why didn't you hire someone do it?
Why not keep the AM manifold as a memento? That's what I did with my less than successful attempt to graft two Volvo intercoolers together for my home made SC setup.

I have two of them! i could have grafted them together for my V16 project!
What part of "it is easy" would apply to greg or carl, before it would apply to me. you dont think greg could graft 8 custom short pipes to connect these two? i figure it would be an order of magnitude easier than building the entire intake.
