I know tons about GM V8's and general engine workings, but I don't know crap about VTEC. I'm only guessing, but does it use some sort of solenoid actuated mechanism that alters the timing of the cams at a certain RPM to gain top end? If this is correct, what are the cams driven from?
Anyone who would like to help me expand my knowledge, please respond.
Thanks.:thumbup:
