from what i here the vtech thing is supposed to be a valvetrain thing that is supposed to improve the volumetric efficiency. from how the my honda friends talk about it, they act as if its some boost as if its like a big turbo lag that doesnt hit till around the higher rpms

RE: Me vs civic si
"Honda's VTEC system is a simple method of endowing the engine with multiple camshaft profiles optimized for low and high RPM operations. Instead of one cam lobe actuating each valve, there are two: one optimized for low-RPM stability & fuel efficiency; the other designed to maximize high-RPM power output. Switching between the two cam lobes is controlled by the ECU which takes account of engine oil pressure, engine temperature, vehicle speed, engine speed and throttle position. Using these inputs, the ECU is programmed to switch from the low lift to the high lift cam lobes when the conditions mean that engine output will be improved. At the switch point a solenoid is actuated which allows oil pressure from a spool valve to operate a locking pin which binds the high RPM cam follower to the low rpm ones. From this point on, the poppet valve opens and closes according to the high-lift profile, which opens the valve further and for a longer time. The switch-over point is variable, between a minimum and maximum point, and is determined by engine load; the switch back from high to low rpm cams is set to occur at a lower engine speed than the up-switch, to avoid surging if the engine is asked to operate continuously at or around the switch-over point. The DOHC VTEC system has high and low lift cam lobe profiles on both the intake and exhaust valve camshafts."

RE: Me vs civic si
i guess i got to try it....
hondas are nice tho i drove a accord coupe on stick it was the v6.... that car moves and the clutch is very smooth i liked it...
but it sounds weak, but mustang are so loud but there not that fast..
when i used to hear mustangs before i used to think they have like 500 horses cuz they were so loud lol
i love mustangs for the noise they make i get all my anger out when i press the gas, lol 3 rpm's is enough for me!
