a few nights ago i drove my mate's VTI-S (Sp00n) and i redlined it.
from what i heard from the engine, vtec kicks in somewhere in between 4000 and 5000rpm.. it's very subtle but u could hear something! nothing like my car 8) =P
i agree with coladuna, 3600rpm seems way too early.
just had a play with mine.The between 2300 and 3600 figure 'sounds' abt right. Probly unnoticable cos it comes in so early. But when u hear it come in its pretty obvious. 'feeling' it is another matter.
i had a "play" with mine a few nights ago. accelerating up to 5K+ after each change of lights.
damn .. couldn't really tell. THOUGHT i heard some thign .. it's either the vtec or the engine protesting.
hahaha
all these people and its still not clear when it cuts in :? :roll:
oh well
here's something to do for fun (and it might even help who knows)
when your in a jazz and your going down a hill or capable of cruising along or it may even work when your parked (havent tried it parked yet)
have it in neutral or foot on the clutch. MAKE SURE ITS NOT IN GEAR!!
make sure your listening and watching the tacho!
hit the accelerator as fast as you can so it hits the floor before the revs start to pick up (jazz isnt the worlds most responsive car)
when they do watch and listen as the revs increase (really quickly) but at a certain point the engine will scream and the revs rise much quicker when it hits vtec.
from my observation it seemed to be a between 3500rpm and 4000rpm.
it could be 5000rpm or watever anyone think it is but thats just MY observation.
anyway give it a go if you want and watch out for the rev cut

right from honda's website

lol that settles it! :P
wonder why noone looked that up before :?

i just remembered this morning that there was something on the honda website about this when i was buying my car early this year. Also read somewhere that the engagement of the VTEC system is seamless or something as such
My friend has a 2000 model integra type r with extractors, zorst and power fc etc and you DEFINATELY know when vtec kicks in.
As im new to hondas and vtec i was trying to find the same effect when i test drove the jazz and found nothing... haha
Something i wanted to know (albeit may sound dumb but..) when it sezdoes it mean that vtec only works between 2300-3600 or that vtec goes from 2300/3600 to redline???? :oQuote:
Between 2,300 to 3,600 rpm, VTEC piston engages the two intake rocker arms together. The engagement speed is variable, depending on the input sensor signals from the VTEC management system.

with the aircon full blast it seems to get alot more urge just under 4000rpm but as i already posted the quote of honda website there's not much to wonder anymore
