so essentially putting a big cam like the MS4 in your car is like "VTEC"
hurts low end but dominated in the high end?

So today I witnessed first hand, THE ULTIMATE TOUGH GUY!
And i know what your thinking and it is definitely true, he was driving a mustang gt.... a yellow one at that!
So my g/f and I are crusin on the 101 coming back from scottsdale mall when i look in my mirror to find this mustang all over the road, cutting people off left and right. Im in the middle lane and cruisin at 70, i see him coming up next to me in the fast lane and wait for him to pass.
I wait and wait and he slows down and gets dead even with me, i look over and was just dumbfounded at the sight i just saw. this guy is sitting there with his windows down, the HARDEST stiff arm known to all man, and the most outrageous look of determination on his face.
At this point all I can do is laugh, so naturally I do. He does nothing and still stares, now im cracking up trying to get this guy to crack his "I own a mustang" smirk... Still nothing, now both my g/f and I are hysterical only to **** this guy off even more.
He starts revving mad and jerking the car, granted it did sound very nice, but still he was an idiot. So there is not much traffic ahead and i see him shake his head. I laugh and throw it in third while he took off... Not even before out of third did i pull on this guy, as i look over at this retard, he is sittin there white knuckles and all still with his grin on his face now all pissed because he just blew his tough guy image losing to an lt1.
Great encounter and I hope i see this guy again so i can shake his hand and reward him with "TUFFY OF THE YEAR"

I feel like I've heard this before...

Plus, watching an old flame practice her sexercise and then kicking a few beers back with ya just makes it all the betta =)
Ah, yes, it was a good night.

VVT is going to play a huge part in the engines of the future. I think I remember hearing that GM (others too, I'm sure) has been testing a cam-less motor with pneumatically-actuated valves, which would yield infinitely variable timing. Would be pretty sweet to get a new valve timing profile by changing your tune.
Anyway, back on topic....if I understand correctly, VTEC just changes the amount of lift that the valves get, lower lift at lower RPM and higher lift at higher RPM. Someone correct me if I'm wrong.
GM has a similar thing out in the new I5 motor that's in the Colorado, except it hydraulically advances and retards the exhaust valve timing in relation to the timing gear, so the exhaust timing is advanced at high and retarded at low RPM, or vice versa. Can't remember which exactly.

Would be pretty neat to see a large displacement V8 with VTEC...

Oil pressure rises in the cylinder head and pushes a pin in the rockers of the low speed lobe profiles...Meanwhile the nasty lobe is actuated, and that's where you get the different sound, and performance...It's controlling not only lift, but duration and VTE as well...
