Similar discussion here talking about the benefits of multiple throttle bodies.
Personally I would stick to throttle bodies the benefits mentioned above suits what I look for in the way my RB engine drives on the road.
Saying that on my Formula Renault it has a single 65mm iirc throttle body. Two different engines so no comparison but it is fed with fresh air from the scoop and then down through the plenum through the air filter and into the engine. As far as response goes it's pretty crap low down and only and we always keep to the power band from around 4800-7250rpm. As far as I can remember F3 uses throttle bodies but totally different engine and concept as these are spec race engines.
