A g35 owner recently insisted that turning the VDC off enhanced the straightline performance of the 3.5 engine. He likened VDC to A/C in that it leeches power and torque from the engine to operate. Taking into account the usual discount one applies to the owner of pseudo 350Z (joking), does this G35 owner's statement have any merit? He insisted that if I turn the VDC off there would be a perceptible difference in acceleration and response. I've yet to discover it. Anyone else?

 

Run a search on VDC or simply read your owners manual or Nissan or Infiniti's website and find out what VDC is/does and you will find that this thread just might be a little silly...

 

Hell, I run with my VDC off for the most part. Nothing pisses you off more than wanting to give 'er hell and it hesitates (similar to hitting a red line fuel cut) . . .

VDC = good for normal driving aka Driving Miss Daisy
VDC OFF = Testosterone Valve Open

 

The G35 owner's statements may be correct in their result, but it sounds like his reasoning is a little whacked. Turning the VDC off may enhance the straightline performance of your car, if you are experienced enough to launch properly and limit wheelspin. VDC only comes into play if wheelslip is detected (in straightline situations). Then it does cut power to the wheels. His comparison to A/C is off the mark. VDC in and of itself does not leech power and torque to operate. It is basically a program running in your cars ECU monitoring and comparing information it receives from wheel speed, steering and yaw sensors. Probably consumes about 1/1000 HP when it is on.

As Mr. Potato Head pointed out, it sounds like the G35 owner could use a little primer in what VDC is and how it works, because it sure sounds like he doesn't have a clue about either.

 

Very well said

 

i bet VDC has something to do with the tire wear ....

because when i have it on it feels like my car PULLS to the right or left... when its off.. its smoooooooth..
*that is when just driving straight*

 

It is very, very unlikely that VDC has anything whatsoever to do with your car pulling to the right or left, assuming that it hasn't been activated.

 

The only way the VDC could cause a pull is if there is a fault in the system and it's applying brakes to one wheel. I would think however that the symptoms of this would be more dramatic than a slight pull and that a dummy light would be on.

 

I've noticed that I'm more irritable with my VDC on.

 

I get a headache when I take VDC.

 

Dont worry man, I picked up on the sarcasm.

 

Is this one of those sexual diseases my mom warned me about?
