Any proof of this? I mean the rotating assembly should be balanced, so this should only affect the car at idle.
The rotating assembly is only balanced so far. the only production engines that are perfectly balanced to come out of a honda plant are the Type-R engines which are perfectly balanced and therefore dont need the harmonic balancer the other honda engines need. If you put the Type-R non harmonic balanced crank pully and put it on an engine that needed one you will damage the engine over time due to its addition vibrations. You will get away with it for a while, however in time it will damage your engine.
The fact that honda spend billions of dollars in designing, tooling and manufacturing the balancing shafts point to them being needed. If honda could get away with out doing this it only makes sense to do so.
There is no state mandate saying cars over X liters need balancing shafts, the reason honda puts in EGR parts is to comply with governmental requirements of the markets it sells its cars in. since no mandate requires these shafts to be in an engine, and honda puts them in at great cost over the millions of engines they make they have a darn good reason for putting them in.
As stated before I will never do this mod to any H series engine i will ever own, nor if such a mod was done, Wouldn't buy that engine/car. It tells you the person who modded the car/engine before cared more about going fast then the longevity of the car/engine. It will have been raced on and who knows what other sketchy things have been done as well. I'm sure i am a small percentage of people thinking of it that way but thats how i view it.
