You know the droning to wailing roar you get from the air going into the engine when you give that V8 a bootfull :-P With carburettors you can have either a two-plane manifold with 4 cyls sucking the left barrels and the other 4 sucking on the right barrels, or a single plane setup where all 8 cyls go to one big hole under the carb. They both sound a bit different to each other. What I want to ask though is how does a single plane manifold compare for noise to a bunch of bananas injection setup where they also suck from a single throttle body? The difference is though that these banana shaped pieces of pipe are a certain length so they resonate and help fill the cylinders more than otherwise. Does this resonance actually make more inlet noise? Maybe someone that hast tried both injection and carby on the same engine could answer this.
