^ Is there any reason you're beating on 4DGS so much?

 

it's been around for quite a while

Why do most 1/4 machines go to some type of automatic when the hp/torque get to a certain point?

 

your VDC must not be functioning properly... I've never know anyone that didn't notice the obtrusive brake and fuel cutoff of a spirited hard corner (particularly 90 degree turn under heavy acceleration from a stop) - and also launching. It does this much less (if at all) when it's turned off (hardly at all with Quaife)

It is very, very noticeable when its on.

 

everything i have read over the past decade or so indicates that AT's have more parasitic drivetrain loss than MT's. i have always been led to believe that AT's, depending on many factors, can sap 15-20% of the flywheel HP. MT's on the other hand, lose 10-15%. so, in general, AT's "consume" about 5% more HP. AWD/4WD drivetrains will negatively affect this number.

i believe this to be a well-accepted fact that i assume most readers of this thread are aware of. it's hard to tell what the point of the thread is anymore, but it seems some people may not understand this.

 

I think he meant different in transmission shift patterns...not actual use when the wheels slip or the car yaws.

The Vehicle Dynamic Control is just traction control...and I don't know of any system that affects transmission shift patterns as part of traction control.

With mine on or off, i notice no difference at all...unless, i spin up the tires or something. I played with it on my ride home today. VDC on/off, auto or manumatic...no difference at all.


Personally...i keep mine on all the time. I'm not a particularly aggressive driver and the AWD kinda puts a damper on my powersliding my corners

 

Consistency, and simplicity of the launch....plus built autos can take SERIOUS Horsepower

I've drag raced both trans at the track. An Automatic is MUCH more easier to launch and race at a track than a manual trans. I find my times with an auto are usually +/- 0.2 tenths while my times with a stick can vary even greater...if i don't miss a shift or bake the tires off the launch. Even if the auto is the faster car, it's easier to launch. Driving a powerful manual trans car is a very tricky art. Notice i said art. I'm sure those of you that have been to the track have seen plenty of Zo6's and other fast cars running high 14's. I'd bet they were prob manual trans cars.

Driving a stick is a skill. Most can do it to get from point A to point B, but in terms of racing, it requires touch to put the power down on the launch and execute your shifts properly.

I have a friend with a 1000HP Mustang (i kid you not) that was determined to keep it a manual trans. Car is actually a street car with 17" wheels, A/C, 1500watt stereo, etc. He struggled to get the car out of the 11's due to a VERY difficult launch. Plus every time he shifted, the car got a little squirrelly. He would snap axles all the time dropping a clutch on slicks. He switched over to a built automatic and the car was an instant 10 second car, and he even dipped into the 9's this past season.

Both cars in this vid are autos. My friends i spoke up above is the Yellow car in the far lane. This was actually a poor run for him but he runs a 10.4 @ 146MPH while the green car runs 10.4 @ 123MPH

 

Exactly. How good do you think the people here are that are trying to tell everyone shifting a manual is faster than even a torque convertor based automatic (that let's say has at least 4 forward underdriven gears)

 

if thats the case then I agree - VDC does nothing for shifts, acceleration (other than traction) or any part of the transmission... but it is very annoying when it kicks in during spirited driving... I leave it off when its not raining - its actually a hazard imo, I've had it freak out when I tried to accelerate out of a sticky situation - the f-ing thing bogged me down and almost got me hit. I'll control the car thank you.

 

Safe to assume that 99.99% of the posters in this thread here have an automatic transmission?

 

My current car is an auto but my all my previous cars have been manuals (and I've modded them all)

 

You know... there's a saying about the word assume... but that's for another time....
To answer your question, no. I've owned both. Mustang just said he's actually raced both at the track. I think DaveB has had both too.

 

safe to assume that this one will beat yours if you are NA. and I'll take the offer you were giving earlier in thread

oh and btw - yes I've owned MTs (and driven plenty others). Figured I'd add that since it seems prerequisite.

 

holy wheelie batman!. I can't believe the yellow one had such a terrible launch and almost caught up at the end

 

Special offer for 4DGS only

I do however have a manual car which I'm not sure if you want to test out. It should run low to mid 12's when it should be done this month, given I don't go E85. But that definetely isn't NA, I give you handicap?

But for the G35 it is auto (incase people didn't know), it is by choice and it is a good auto I just don't make it out to be God's gift to mankind.
