4.6.8 fuel/ignition starved certain cylinders during points where all the torque all 8 weren't needed...I could be wrong but I don't think it had much if anything to do with the valves...
*edit* I did some looking around and the only thing I could find is ONE guy who said it "lifted the camshaft to keep all the valves closed" but that doesn't make much sense to me... *?edit*

My vtec engine as well as ALL b series vtecs are performance minded... I don't know crap about the f series or accord engines... like I said it's EITHER performace z6, b series or economy d15 the one's hondamaniac mentioned...

the vtec in my car has NOTHING to do with gas savings... it's smaller profile lobes are to get the most power at low rpm and the biggers are to make the best top end... niether are for fuel economy like the d15's in which 1 valve opens lower than the other to create a better air/fuel swirl making it possible to run leaner... ie less gas....

Turbo's are about the most fuel efficient mod you can do to your car... so what you're saying is dumb... Of course you add more fuel because you've effectively increased your displacement... it's till FAR more fuel efficient than a car making the same power na. beyond that.. My comparison to turbo was a JOKE...

turbo: adds power ONLY after it spools (2-6k)
vtec: adds power ONLY at a certain rpm range (4-7k)

they are BOTH power adders and they BOTH leave you with a piss poor bottom end... the vtec is just a REALLY CRAPPY one that takes FOREVER to kick in... it was a joke.

I'm comparing cars in the SAME class... A 1.8t is DIRECT competition with the civic/integra... so is the vr6... just because they use displacement to make power instead of vtec doesn't make it an invalid point...

want a more valid point... my sentra had a 1.6 that ran MUCH better than my civic and it had a MUCH more linear powerband... and it's not even their sport model...
