As the title suggests , i'm curious to know what benefits i'd get out of twin throttle bodies on my EA with BBM. Just want to know theoretically what would happen if i made an adapter (like the 2(or even 3)in to 1 exhaust style join) This would look particularly sweet with a twin turbo setup. I already have a high rise hornet scoop so i have the room to do it. The throttle cable is an issue but can be fixed with linkages. Anyone????
don't know if there would be too much benefit, could be benefitial with TT's, but probably not worth the cost, i'm fairly sure someone has done it on an EF/EL and saw minimum gains, but it leaves room for the setup to scale.
the only issue i can see with a TT setup wtih dual throttle bodies is that if you were to have an intercooler... piping would be a nightmare!

for looks value, with a turbo install, it would be worth it - if you polished everything it would look great - but as far as performance goes i really think you would be wasting your time.
also, if you are dead set keen on turbo/s, retain the standard multipoint intake manifold, or get an ED one (allegedly they are larger internally, i dont know for sure) it is MUCH MUCH easier to route the piping for the turbos, it looks much neater, and if you polish the manifold it looks awesome.
the ED manifold supposedly flows as much hp as a EF one (or more, depending on who you talk to) but has better cylinder filling at high revs due to the plenum design, EF onwards has no plenum as such, just pipes going straight into the ports.
turbo guys reckon that for best power/driveability you need an intake manifold/plenum that can hold about as much air as the engine (in our case, 4 litres) and the ED manifold is about 3.2 i believe, which is as good as your going to get unless you start cutting and shutting stuff.

You've gotta remember that it's the more air into the CYLINDER that gives more power, so you'd need your head, cam, etc. to flow enough to make use of it.
By putting twin throttle bodies on, you're basically just getting more air into the manifold, which won't really be able to flow any more into the ports on the head or through the valves into the cylinder.
