Why no dual intake?

[Ctease]

This is an Audi single plenum single throttle body intake manifold used on their old V8s. Was dropped when they introduced VVT cam pulleys. The VVT acheieved wide torque curve without variable intake system.

Thanks very informative posts. Exactly what I was looking for.

I think in one of the interviews back in 2015, they mentioned fitment being an issue.

I think in one of the interviews back in 2015, they mentioned fitment being an issue.

This exactly, it is also why they made the Flat plane crank up-down-up-down instead of the traditional up-down-down-up used by almost every 4 cylinder and FPC V8 made. It comes down to acoustics and pressure waves. an inline 4, because of the space between the firing has a beneficial pressure wave at low to mid RPM which helps VE. In a traditional FPC V8, these would smash into each other from the different banks and hurt VE. so the ferrari engine functions like two I4s bolted to one crank. The problem is that they are very tall and would not have fit under the GT350's hood.

By changing the firing order, the engineers were able to use a single plenum and throttle body while only loosing some low and mid range torque.

At high RPM the Ferrari engine has valves that open, combining the plenums to take advantage of the harmonics between the intake pulses. The Voodoo obviously does not require that saving space and complexity.

How dare you offer up such a concise response!

Tear it up MCarsFan!

Touche, I forgot a fart joke. And my flared up torched hair.

The dual throttle-body design is engineered to accept two 90-millimeter throttle bodies and is ideally suited for twin-turbo race setups.

That looks a lot better than the red plastic engine cover I had on my Z06 lol.
