What’s the tuning logic of the intake manifold? Torque peak around 3500-4000 rpm with the stroker?
I'm actually not looking for MAX torque or hp, as it's just a street car. Of course I'm hoping to get 'real' driving torque after spending a lot of money. I've never liked the idea of air intake going all the way to the back of the engine, then, to go down into the valley heat, rise up again, split and do a 'U' turn before it can enter the inlet runners. I simply wanted to take a short cut and I like the look of the Audi R8, so I thought I give this a go as 'mark I'.
the dyno will tell, eventually?

The other thing is that I don't want any of the old cable controlled stuff. I'm going electric hood release, cruise control, gas pedal and throttle bodies.
The Cayenne Coil-On-Plugs get rid of the coils, distributors and all the plug leads. It leave a 'clean' looking engine, I think.
It was very tricky to get a design that allows the manifold to be bolted on, the air intakes to be bolted on and still fit the fuel rails in. I get there with 0.0001" to spare.
that intake is kick ***.
flappy deleted? 6.5 liters should make up for the "torque boost"....max breathing FTW.
Yes flappy delete. This is an '89 S4 manifold I've adapted to fit my '86 motor in place of the 'organ pipe' system, as it was the easiest way to get what I wanted.
It did involve some head and manifold Dremel grinding to get the ports to match up.
very neat project.
i am putting an 86 928 head onto a 944 block and made a similar "gasket adapter plate" to use a 944 DOHC manifold (visible gasket).
928 DOHC heads (at least in US) are cheaper than 944 DOHC, and they come in pairs

I like your cam follower holders. I discovered the need for these the first time I turned the engine on the stand!
Finished the trans oil cooler, tucked up under the RH rear seat. I did plan to have a temp controlled fan on it but it's too tight and an over kill for my intended use. It will get plenty of air flow and no rocks, I hope! The Stainless steel under cover will take quite some belting before it exposes the core.

That's no longer a car....it's a piece of jewelry!
That is an impressive engine. Can't wait to see the numbers.
Audio: For amps, I love my Pioneer GM-D1004s. I have two of them bridged providing 90w per channel at <0.1% distortion (excellent for car audio) under the passenger side cover where the lame Porsche factory amp was installed on later cars. They fit perfectly and play clean and loud at concert volumes. I couldn't believe the power coming from these tiny boxes.
Hopefully, sometime before I die! As I tell my wife, "what would I do if I finish this?"
Seriously though, I have no completion vision. It will happen when it happens.

I look forward to the engine output figures also. That is kind of the big money side of this project but the numbers aren't my 'big dream', I just want a torquey street car.
The sound system scares me a bit. What if it spoils the sound of the engine?
Exhaust will be much like the early 'S' cars by way of path. 'X' pipe, 2-in-2-out high flow cat, 2 pipes down the middle, turning to the left side, a 2-in-2-out muffler under the LH rear seat, then 2 pipes out in the original 'S' tailpipe spot.
If it's noisy, I'll put a resonator just before the tailpipes.
I would love to have extractors but as I'm doing no cylinder head work at this stage, I don't really see the point. I have a spare set of heads and I'd dearly love to have them professionally modified but that is not in my current budget.
Though it may not look like it, I have to work strictly to a budget!
