How VTEC Sound Like
This is what VTEC should sound like. The crossover to the high cams should
be linear without any power loss. My car was tuned to make maximum power
across the RPM range. This was done in 4th gear.
I Dynoed 210whp &
154wtq on a Dynojet.
Car: 2008 Honda Civic Si FG2

VTEC kicks in at 4k RPM all the way to a redline of 8.6k RPM.
"VTEC (which stands for Variable Valve Timing and Lift Electronic Control)
is an electronic and mechanical system in some Honda engines that allows
the engine to effectively have multiple camshafts. As the engine moves into
different rpm ranges, the engine's computer can activate alternate lobes on
the camshaft and change the cam's timing. In this way, the engine gets the
best features of low-speed and high-speed camshafts in the same engine."

My second pull I shifted too early because I was focused on the camera that
was moving around. Bottle was close to empty so it had low pressure. Thanks
for watching and enjoy.
