C7/7.5 How to Launch

[Ze_Nardo6]

Great thread Doc. Here is my take from the 20+ runs at stage 3 levels thus far

I'm not totally throwing in the towel just yet on using launch control at this power level, but it did not bode well thus far. I tried a 3k launch which came off the line well but bogged during the 1-2 upshift. I then tried the 5k launch which was way too much in every way. Massive spin and wheelhop and new underwear required (will never do that again).

I noticed when I wasn't using launch control and was more so "loading" the car from idle (more of an upswing method as you alluded to), the car would come out of the hole nicely and without any tire squeal or spin. The problem with this method was that the car kept engaging in LC and I couldn't "load" the car as I wanted to...my solution was to keep the traction control on as I knew this would prevent activating LC. There is a sweet spot with this loading method that I am still trying to dial in (getting close). I cut a few 1.61 and 1.63 60' times using this method on street tires, which I think are in the top tier for stage 3 S car 60' times. Really excited to give it another go this month back home.

Here is a video of me loading the launch as described above. Not my quickest run but one of my better 60' times. As you can see, no drama off the line and it just goes.

Thanks for sharing that, it will be something I will be trying soon.

In keeping traction control on, I assume the system is interfering a little bit during the initial 60" because of wheel spin... but it's not messing too much with our times?


Recently broke my rear half shaft using launch control on my Stg 2 S6 and was wondering about a different method to try next time out. Will still probably use launch control, but busting things does have me a little bit trigger shy
