Activating Vee-TAKKk!

[93HondaMan]

Is there a way to activate it before 6K-7K RPMS on a D16Z6 motor?

[kommon_sense]

it kicks in around 5500rpms. why would you want it to kick in earlier?

I don't, I dont even have Vee-TAK! A friend of mine thinks he can haul more ass with it engauging sooner.Guess I augh to break em the bad news

you can buy a V-tec controller.. read about tha purpose of v-tec, its like having two cams. one for lowend on tha RPM scale & one for tha highend. if vtec kicks in too early and tha puter is not tuned for it, most likely youll run into troubles.. imo

Warning
· Do not set the VTEC point too low as the engine will lose oil pressure and possibly damage the engine. It is not recommended to set the VTEC point below 2000 rpm.

· Do not set the VTEC point too high as the high speed cam rocker arm may float on the lost motion assembly, damaging the valve spring retainers. It is not recommended to set the VTEC point over 6500 rpm.



The determine the best VTEC point perform two dyno runs, one with VTEC set low (e.g. 3000 rpm) and the other run with VTEC set high (e.g. 6500 rpm). Set the VTEC point to the intersection of the high speed cam and the low speed cam. Generally if there is a sudden increase in engine output immediately after the cams switch then lower VTEC. Conversely if there is a sudden dip in engine output then raise the VTEC point. Since the VTEC point will be at the intersection of the low speed and high speed cam torque curves, it is normal for the torque to dip around the VTEC point.


I'm sure honda set it right for stock

That is so true....ideally you should never tell when VTEC kicks in in terms of a surge of power....yeah you may hear it in terms of intake/exhaust, but if it is set correctly the power band should ideally be smooth.
