Launch Technique For M6

To my experience and based on extensive readings - maximum tire adhesion starts around and above 106F.
Anything lower than 106F and tires will slip and slide.

My EDC setting is almost always at normal / 1 LED lit mode.

It appears you already have your M6 set at maximum / optimum torque and power.

The only thing I can think of would be modulating your throttle to keep the wheel from spinning and getting the best tire grip.

In addition, no matter what you do, you shall never be able to keep up with a Porsche from a stand still. Your friend had a GT3, I can assure you, you shall be surprised how fast the Carrera S is off the line. Absolutely unbelievable.

Yes, its amazing how P cars can effectively put down so much power to their wheels. My friend's GT3 is able to gain 1 car length from a f430 scuderia at launch, and won the 1/4 mile by more than 4 car lengths.

P has the perfect formula for launch. Rear engine, rear wheel drive and a ligt weight body. There is nothing that can best that.

You should see the new Turbos with PDK go. They are absolutely mind blowing.

I tried drag racing my stroker with my friend's tuned GT3, and he basically flew pass me at launch, while my car is struggling for grip. My EDC was at the softest setting, traction with M-dynamic mode, tire pressure at 33psi and tranny at S5 setting.

S5 MDM is actually a LOT slower than S6 DSC off. The only way you will get traction without Slicks/drag radials is going to a track that is prepped extremely well. EDC on softest setting seems to help too, but I still leave it on the hardest setting. For a stroker, I would just ease into it, but for a stock M5/6 just stomp the pedal and go. It will launch your car at 3500 RPM instead of the USA launch control setting which is lower. I have had times of 12.5-12.6 with my heavy cabrio stock by doing that method, and I think that is a decent time for that heavy car. Coupe's should be able to get a 12.0-12.1. I know for sure with slicks you could see 11.9 stock.

Also, the age of your rear tires will make a big difference with regards to how well they hook up. You can pretty much stomp on it with new tires, but I've found that the PS2s get really greasy after they are about two thirds worn.

I ran my times with bald tires too...I want to get back to a track to test it out with new tires.

Driver needs practice to get the hang of it.

Note: based on what I've read - clutch wont last very long after a few runs using Launch Control.
So take note.

THANKS A MILLION whatheheck..... that PDF is awesome. I guess we'll try out both methods and report back

Thanks to all who replied, I appreciate your help

You're welcome.

As you can see, each of us have different techniques.

It is best to experiment and do whatever works best for you.

I agree with M6Cabrio - S6 DSC off mode provides the most power to the wheels.

Just make sure you try the S6 DSC off first on an empty street as the power of the V10 is insane with traction control off, engine and torque set to maximum (S6 DSC off.)

The tires have about 2000 miles on them right now so hopefully they'll be alright.... I just hope we get a nice cool day in SoCal for this event because lately it seems that it's been getting hotter instead of cooler although last year around the same time, it did drop down to 50 F at the track (Famoso) and almost everybody beat their personal best . It'd be awesome if we get a negative DA.

I have a hell of a time hooking up and know with practice I will get better. One night after 6 or 7 runs, trying all kinds of ways and still not hooking up, I tried this... I left the M button off, slammed my foot to the floor and after a blink of an eye, hit the M button. It worked with just a little wheel spin and cut 2/10th off my other times. Is it the way to go, can't say without some more runs.
