..... ^.....
is it when i floor it and i take off then at a certain point really pick up speed and zoom off?
(did a search already ...)

 

You can feel and hear the VTAK

 

from what I know it deals with valve timing at higher speeds, not just flooring it. Read up on it on a webpage, it's not an unknown tech.
Find out what the acronym v-tec means, it does mean something.

 

i know what it means and all that i just was wanting to know how i know when it kicks into effect. i heard around 4k rpms. but unless i drive in 3rd gear and really give it the gas my auto isnt gonna hit that high....
valve timing electronic control. ya..

 

Vtec engages after a certain set RPM point. When it does the cam profile changes to allow more air and fuel into the mixture.

 

vtec on f22/f23 sohc motors engages between 2300 and 3200 rpm, above 6.2mph, when coolant temps are >50 degrees fahrenheit...the exact crossover point is determined by manifold pressure.

with the sohc design it actually has the motor operating essentially as a 12v motor (with half of the intake valves opening briefly and slightly on the secondary lobe to prevent fuel pooling, while the other half follow the primary lobe at moderate lift/duration)...after vtec engages the motor operates on the mid lobe at slightly higher lift/longer duration as a conventional 16v motor

 

Thank you everyone.
esp you street accord got what i was looking for


thanks again !!!

 

Had a customer that tagged a small light to the solenoid and ran the wires to his dash so he could see when the V-Tec engaged
