i have an idea
Idk if anyone has ever seen how the intake on the older ferrari H12's are but I noticed something similar about them to our engine. They have 2 seperate intakes 6 per side, was wondering if that would be a good idea for ours. Would seperate runners help the engine breath a bit more or would it not matter. More or less just split ours, close them and put 1 throttle body per 3 cylinders. Good? Bad? No point? I want some feedback

Re: i have an idea
There are advantages and disadvantages to both, and Subaru was smart enough to give us the best of both worlds. The IRIS valve divides our intake into two halves or opens to allow the cylinders to breath together. I forget what the changeover points are, but at certain points of the operating range we have a dual intake system.

Re: i have an idea
The main issue would be engine management. You would need a system that manages 2 MAF sensors or some other way to measure the air going into the engine.

Re: i have an idea
I actually make firmware for dual intakes. It's not listed on the website but it does exist. It is the same as Stage2Av1 except it uses STI yellow top injectors and twin SVX air flow meters. You tap the wires for the 2nd air flow meter into the wires for the existing air flow meter so that they are connected in parallel. The signals are averaged and the firmware handles it from there.

Re: i have an idea
you pretty much need a balance tube between them or you should be running engine management that can deal with each bank like its a separate motor.
Which I think is why the ferraris used separate manifolds. They could use 2 6cyl bosch systems. |
