Improving Vantage performance via smoother intake airflow?

The image of the intake tubes and trumpets are after the air filrer and MAF. It is a image of the S62 out of a E39 M5.

telum01 you are correct, the image is off a S65 M3 V8. Looks the same as the ones for the M5 so =p.

I believe they just run them open without filters. Some put a metal mesh over them to keep larger things out. People do it with large turbos, too - just a velocity stack and no filter.

I guess that's what I figured. Just seems like it would harm the engine, even if it's just fine particulate matter entering.

Then the tuning and show scenes got hold of it and went with it - first with old school muscle cars with giant blowers sticking out of the hood, then the import tuner crowd with giant turbos or open ITBs (like the pic above).

Intake wise, dual throttle bodies sound sexy but in my opinion it would be a programming nightmare. You would require independent torque based electronic throttle programming and Equizzer checks for each throttle body to be safe. It is not clear to me if such programming could be duplicated on the single ECU of the AMV8. You would likely have to run 2 ECUs or go to a completely aftermarket system.
For example, take a look at this manifold. It uses two throttle bodies, but they both feed into the same manifold at the same place.

That's what I've been talking about doing all along
The TB in the pic you posted is the same I linked to in this.NOTE: I was saying "dual TB" when I meant to say "dual-flap TB" *woops*
I think a more feasible solution, would be to adapt the OEM intake manifold. Cut the front of the manifold off at the taper, fabricate a new front that tapers to a dual TB setup (much less taper due to wider TB housing).
Here's my wicked sweet, highly-technical design.
By having a dual TB setup, airflow will be coming into the manifold on the sides of the wall, rather than pointing directly at it. I'm guessing this could improve throttle response quite a bit. Ford Racing makes a couple dual-TB setups that might be suitable. One is 2x63.5mm and the other is 2x65mm. Assuming the pivot bar is the same size, the 2x65mm TB should have a similar opening. However, the TB will open faster with a dual-plate setup than single, so more air will come through quicker at the same throttle position (all else being the same). That should mean better response - so long as the tune for the new setup takes it into account and the throttle doesn't become too touchy. (For reference: http://www.summitracing.com/parts/fms-m-9926-cj65)

I know what you meant. =)
The AMV8 is a Ford based motor from what I was reading or am I wrong? That intake I posted is off a ford V8 so in theory could you use and adapt those parts to a a AMV8 with some minor modifying?
Just a thought.

The chances of the Ford intake manifold properly mating up to the AM block would be very slim, and modification of the runners would be extremely difficult.

AH got it, must have misread the motor report.
The area in orange is the par in theory you need to match up with. There has to be something close that matches up to that pattern.
