when DOES vtec kick in?
so i was reading this post.... http://www.team-integra.net/forum/di...urnPage=Search
and they are claiming 4400-4700. Now i drive a 97 gsr, and when i floor it in 4th gear (so i can hear the rpm's clearer and slower) i can hear a change in sound at 4700 and then vtec @ 6k (on the dot). Someone told me that the butterfly opens at 4700 (in the TB?)
Anyways, what is the stock vtec crossover/engagement? And what is the butterfly/when does it open (Besides full throttle) lol
Thanks

The cams switch to the VTEC lobes at 4400rpm.
