what do you guys think is better? The stock Dual Butterfly manifold or wouldyou go with an aftermarket like a Skunk2 or JG Edelbrock?

is the Dual Betterfly manifold any good? some people say its a really good disign and others say its garbage.

what is the benefit of having a dual butterfly? is that what makes the VTEC kick in twice?

Thanks everyone

the vtec kicks in. then the iabs switch over.

as far as your question goes, it depends on your setup. the gsr mani has 2 sets of runners. it uses the long runners at lower RPM and the short runners at high RPM (switches around 5500). The benifit of this is that there is a shockwave created when your intake valves close that travels to the back of the manifold and then bounces off that and travels towards the valves again. with 2 sets of runners, this shockwave can be timed so that it is pushing the air back into the valves right when they open again. when your engine is at higher rpm, the shockwave has less time to do its thing and get back to the valves hence the shorter runner.

now is that a good thing or just bullshit. i don't know. for a stock engine, i would stick to the stock manifold. if you are boosting or have a built motor, i'd step it to a skunk2.

Hmmm... good question. I wouldn't mind knowing the answer to this one too.
