What's the best launch technique?

There has been a lot of discussion of 0-60 times for the 135, but how are drivers getting them?

I'm curious: what rpm's at launch, pop or slip the clutch, etc.

I haven't had to embarrass a Shelby Mustang yet, but you never know when the need will arise. I could find out through trial-and-error, I suppose, but in my case that usually involves so much error....

In the May issue of Road & Track they wre getting 4.8 second 0-60. Their technique was traction control off, 4000 RPM and release clutch smoothly. There should be just a little tire slip. I don't have mine for 2 more weeks, so I can't confrim how this works - and then there's that break in thing.

I heard they ran 4.7 with automatic? Is there such thing as launch technique for automatics other than just hit the gas and go?

Yep, a little bit. We touched on that subject here...

4,000 seems like a lot of rpms, given how much torque this engine has. Won't it just sit there & smoke the tires? Especially with only the e-diff functioning?

Plus, in another thread, I ran across this quote from a 135 owner with an automatic: "Launch at 1800rpms on a dry sunny day on decent ground and I don't see any reason a 4.7-4.8 0-60 is not possible."

Somebody's got it wrong.

I'm wondering if anyone who doesn't work for a magazine has tried an actual, real-world 0-60 run, and how they did it....

I must have missed something, where are you reading 4000 rpms? The thread I posted mentioned around 2000 rpms...

EDIT: Nevermind, I found it in this thread. Man I'm easy to confuse today. That was for an MT but you are right, even for that 4000 would make a wicked burn spot.

That was me who said that! :biggrin: I should have added in there that I did that in an auto transmission. For me I found that was a sweet spot and any higher RPM the back wheels would start to spin or I would get too much wheel spin off the line. 4000 RPM launch for the auto would be great for a smoke show!

Maybe on the manual you might pull it off if you let off slowly. Not sure haven't driven this car with a MT.

In another test I read they launched the manual at 4500 rpm's. Letting the clutch out easily. Yes this is the way.

This is also the way to burn out your clutch, throwout bearings, etc. quicker. Letting out the clutch slow enough to not peel out at that RPM tends to put a lot of wear and tear on your system...

Launching at 4,000 rpm in a muddy field with wings attached to my car -- now, I can accept THAT....

Road and Track did not pay $40000+ for their car so I would not take a chance with that method. Sound like trouble to me.

I would probably try around 3000-3500 and smoothly let out clutch to avoid bogging down.

i read a review that suggested 3500 as the best in terms of generating an ideal amount of wheelspin at launch.
