take 2 head units of your choice, be it twin turbos, twin blowers, twin centri's, whatever.............instead of using a common plenum, set it up in banks or sides. For simple math, lets say we have a 400 ci motor, or 2 200 ci halves......since I'm not very familiar with turbo sizing vs. ci displacement .......let's take something old, cheap, and plentiful........2 M90 Eaton blower head units, 1 for each 200 ci side. Let's say we go MAF-less for ease of intake routing.........(thinking out loud).....do we keep the exhaust systems seperate? or do we merge them............any other issue's we may need to consider?

 

Have you tried some Ambien?

 

A true positive displacement blower like a roots style would be the best I feel, that way you know each side is getting the same amount of air. If you use a turbo and you have a miss on one cyl then the turbine on that side won't be pumping as much air. Regaurdless of which type of FI you go with I still feel you need at least a balance tube between each intake bank.
On another thought, the best set-up I can think of would be a supercharger and turbo. I think this has already been done, but have a turbo pushing all the time and have a clutch on the supercharger (maybe an electro one like on a a/c compressor) and have the supercharger disengage at around 3k rpm for example to take care of turbo lag. I'm thinking Mercedes or some company has at least toyed with the idea.

 

vw has that system.. i think they call it twin charger or something like that

 

well, I had the country right! Hail farfignuggen!

 

On a recent episode of xtreme 4x4, Gale Banks designed a turbo system for Urban Gorilla that has twin turbos and twin plenums. Looked pretty cool to me...

 

I think you might still want some type of a balance tube between them. Some did a twin supercharge set up but it had a common plenium. Blowers were tilted but still fti between the valve covers.
The exhaust I would run them together or some form of a cross over, again that balance thing.
If you split the banks perfectly you now have 2 4 cylinder engines. Not sure what the harmonics would do.
It would be an interesting test.

i was thinking the same thing i wasn't real impressed though because the stock d-max has made more power then what they made. but i guess they said theres was makeing it easier. or something.

 

What exactly would the advantage be splitting the plenum? I guess all I see is potential problems with this setup.
