Thanks. Yes we had at least 50 to 60 launches that day and we tested it both in race start and brake torquing and found that the best results were from brake torquing where you release the brake at about 2500 RPMs.
To do it properly you step on the brake first and floor the brake. Then your floor the gas and simply let the revs come up to about 2500 and release the brake. it's that simple

Because as soon as you floor it, you will have to immediately lift off the brakes, as the RPM will climb so fast, it would be very hard to catch before it passes 2500 rpm
Also 2 feet or one foot?
Thx

Attached is a log from yesterday. All runs done in S mode. What timing advance are you guys seeing at WOT? I see a couple of degrees. Cooling seems to be OK on these runs, which is great.
Interesting that I see 22 lbs of boost, which is about 3 lbs more than I had seen in my other logs, which were all logged in S+ or M. I remember seeing another member post he sees more boost in S as well. Mine could be bad data also, but just throwing it out there for the group.
...data sorted by boost, low to high

Pretty sure sdg has quickest documented e63S on this board with just tune and mufflers

i reliably get my best launches with sdg's technique... I don't bother with race start anymore

Sorry for what might be a stupid question. But I am planning on heading to the track here in NJ this weds evening.
It seems that the technique that is recommended is to side step the brakes as the RPMs hit 2500 as the floor the throttle? Or are you saying to hold the RPMs at 2500 side steps the brakes and then floor it?
Out of curiosity what is the issue with the RS mode?

2 add throttle slowly up to 2500 rpm
3 foot of the brake
4 100% throttle
RS just slower

Went to the track this evening, as we finally have some cooler weather (71 degrees). Launched at about 2100 rpms. 50/50 mix of 93 and 100 octane fuel.
Run 1: 11.548 @ 126.70 mph (My best trap speed thus far)
Run 2: 11.577 @ 124.95 mph

From what I've tried on the street RS seemed to launch harder than brake torque.
