not really. VTEC engages at higher RPMs, not whenever you want it to engage. it's not saving any gas at all. |
actualy it sorta does, think about what you said it engages at high rpms, so unless your racing or ****** around why should you be at high rpms??? so in a way you do save gass |
everyone saves gas if they don't go into high RPMs.
VTEC is a way to extract more power out of a tiny engine by switching to a different camshaft at a certain RPM (somewhere around 6000 or so). |
even if you arent in high RPMs, the engine is still using less gas because of the less aggressive cam pattern. That way it can get great gas mileage, and still make a decent amount of power for the engine size. |
i don't think you're getting the point. the VTEC system entails the use of the more aggressive cam. when the engine is below 6000 RPM, it's using the regular cam. it's like any other 4-cyl. |
yes...im not getting the point. How do you know that the less aggressive cam is the same as the SOHC motors? It could be even less aggressive, so that it can use less gas. Dont make assumptions if you dont know the facts. I dont know the facts either, but its a good bet that the VTEC motors are more fuel efficient than the SOHC non-vtec motors. and do you know why? because the VTEC system is made to save gas.
Its purpose isnt to make horsepower, its to be more fuel efficient, along with all of the other acronyms (i-vtec, vvti, whatever.)
And cbrmike, i dunno about you but last time i drove a 4 cyl car i had no problem keeping it under 4k in normal driving.
