High and Low VTEC!! :laff: :laff: Thats a new one. I knew what you were trying to say though. Not flaming, just being funny.#17 said:lo vtec is at 4400 and hi vtec is at 5800
Acurabro is right on this one, the GS-R has a dual stage intake manifold, unlike the ls and type-r which only has a single stage intake manifold, at 4400 vtec engages and when you hit 5800 the butterflies open allowing my air to pass through, creating the loud sound and depending on the setup the sound can be pretty loud4400 to go from small lobe to mid, then 5800 from mid to high. The most noticeable difference is at 4400. The "VVIS" Variable Volume Induction System" also activates at 5800, basicly your intake manifold butterfly valve opens then and lets the air go though the short-runners.
AcuraBro, article was just to show when VTEC engaged for the GS-R since everyone had their interpretation on the whole subjectMaybe if you're driving a Civic EX, but in the DOHC VTEC Camp, there are 3 seprate and different cam lobes Per 2 valves. So you're saying that one of the lobes and corresponding rocker arms is there for no use but dead weight? Me thinks you on crack. Type R is Single runner intake manifold. Don't post things unless you know what you're talking about.

What does the LS have? I didn't know it has some engagement device like VTEC in its IM?HondaTegGSR said:... unlike the ls and type-r which only has a single stage intake manifold...
