why don't you just go out and drive around and try it. it's when your car jumps to speed a little. to make V-Tech work, your car must warm up nicely. You can't start your car up, and and floor your car and expect a V-Tech. I personally dont like V-Tech

Ok my video went completly unnoticed. VTEC is really just a slight improvement nothing major. i mean technically the roller-liffters on a corvette engine do what VTEC does, by using rollers instead of direct contact lobes you can get a more agressive lift at higher rpms. VTEC is not some magical power that makes your honda a Formula racer... i believe toyota also has a variable valvetrain system and you dont see them making a huge deal out of it... just drop it!
since this started last year im not sure which year this thread is the worst in... so its the worst thread in 05-06

BOTH EXHUAST AND INTAKE VALVES ARE LEFT WIDE OPEN AT HIGH RPM RANGE THUS MORE HORSE POWER AND TORQUE. this forumn is full of noobs!
I may as well correct you since you insist on being an ass. SOHC VTEC only has a variable intake cam, not both exhaust and intake, which Honda's DOHC engines carry. Because of this, DOHC VTEC usually is far more effective as far as power figures go. The lift and duration is also much more aggressive on these motors than the lowly SOHC counterparts.
Secondly, this SOHC VTEC Integra you speak of, I have no idea what the fuck you're talking about. VTEC was first introduced in the NSX in 1989 and has since then made it's way through the Honda lineup.
My point was initially that there is such a small performance gain from SOHC VTEC that I was surprised that people were still arguing about it.
