Since I didn't win Mega Millions last night I decided to go to opening day at Great Lakes Dragaway in Union Grove Wisconsin today. Track conditions were dry, even though it had rained a bunch the night before and misted on the way there this am. Temps were cold, 39 when I got there and 73% humidity. I was only the 15th car when I got there at 930 am. There were probably 75 when I left at 2pm.
I only practiced launching a few times before going to the track, my car only has 1800 miles on it. 4500rpms seemed to be making the car come out of the hole pretty nicely on the street with just a hint of front tire spin. Things were different at the track with all the rubber and vht on the ground. I wound up having to launch in the 5500-6000 rpm range. Surprisingly the clutch held up just fine the entire time. I wound up making 21 passes in total, almost all of my 60ft times were between 2.0 and 2.2. Never once did I actually "slip" the clutch to the point where the engine revd freely with the clutch all the way out, this clutch held up to some abuse today. I only smelled clutch once or twice and it was after the first couple passes. If you get it just right the car will really come out hard with no bog and no spin, it feels incredible. I imagine this is how launch control feels every time
Car specs, 2 door R, no sunroof, 6 speed manual(Obviously, its a US car) Completely 100% stock. Stock suspension. Stock Dunlop tires set to 40 psi. No mods whatesoever, stock paper air filter, stock oil etc. nothing has been touched since I took delivery of the car 3 weeks ago. No weight reduction. The full interior was in place, the factory jack, spare tire, tools etc were all in the car, it was completely full weight. When I began the day there was 3/8s of a tank of gas. Unfortunately the scale at the track wasnt working so I couldnt get the weight of the car.
Pics of time slips are below, I wont bother posting all 21 of them but the first 8 in sequential order leading up to the fastest of the day are listed. They are in order by time of day, the date is wrong, it says April 1 2012 but today is March 31 2012. Keep in mind this was not a pro tree so reaction times are NOT factored into the ET. I was going for good launches not fast reaction times as you'll surely see! Some of the slips are cut in half by the track people because the bracket racers that are practicing don't want you to know their times. My best pass was my 8th pass, firstname.lastname@example.org mph.
It would be really nice to have a data logger so I could see what I did for that 13.95 pass because I was not quite able to get there again, lots of 14.0x but no other 13s. I know the 60ft time of 1.980 is what did it but I'd like to know what rpm I launched at. Unfortunately I was alone so I wasn't able to get video proof. There were people taking pictures and videos, hopefully I'll be able to find vids of it on the track website or some midwest racing forums. For now all I have is the time slips. I was car number 415.
My overall impression of the 14.2 second estimates that car magazines have been giving our car are dead nuts accurate. Thinking in terms of normal street driving conditions and what rpm people are willing to launch at I think 14.2 is on the quick side but still reasonable for a stock Golf R. Removing all excess weight from the car, adding a short shifter and a dogbone mount bushing and installing lighter wheels could get this car consistently in the mid-high 13s with a completely stock engine.
