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
Tune: Hondata FlashPro
Mods: I/H/E

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."
