Long subject line, I know, sorry about that.
So I smoked a GT mustang today, an older one, probably early/mid 90's model... wasn't even close. Only thing noteworthy about it was that the guy wasn't mulletized, he had more of a "horseshack" from welcome back kotter thing going on - white boy mini-fro, if you can dig it?
Scary.
So anyway, my questions/observations about launching - with VDC on, I don't get the spin and hop that I got today launching with it off in this little stupid street race - so someone explain to me again why I need to turn it off to get the best launch? It steals power to KEEP the wheels from spinning, is that correct?
It didn't seem any faster with it off, I launched at around 3k I think and seemed like I just spun wheels forever... So what RPMs gives the best launch with the VDC off? Just looking for everybody's .02 on this.
Spanks.

 

LMAO @ mullet joke. Great kill dude. As for the VDC thing...Ehhh I dunno.

 

Try it at the track and you'll see that with the VDC on you'll be .3 to .5 sec off your 1/4 mile time.

I find that 2000 RPM with slipping of the clutch gives a good compromise of wheel spin and fairly quick take off....with the VDC off that is.

 

Well, I've been told several times that a tire gives the most grip when just barely slipping. Therefore, you best launch is one that gives you a slight hint of wheelspin.

I never really understood why people say this though, because the coefficient of dynamic friction is ALWAYS less than for static friction....

 

Because with a little bit of tire slip you don't bog the engine. Technically from a standstill with 100% locked up powertrain and tires, your engine prefers to be @ 0 rpm. If you can launch at 2000 rpm, building power, you'll get a faster acceleration run than if you leave the line with biting tires @ 6-800 rpm.

 

I like to shirp and go...
