Keep the slips comin’
That is my reason for getting the Dragy. Actually I shared the purchase with a couple of friends. I have Cargraphic headers and OAP on order from BGB. I want to objectively validate any gains from the mods.
BTW, I could not load the Dragy on my phone due to no signal where we were at. My friend previously loaded to his phone and we just changed the device between the cars. He texted me the Dragy result slip earlier. The 0-60 was actually a verified 4.29 seconds, not 4.5.
The 1/4 mile time was a recorded 12.23 but I noticed that it did not have a verified tag, and was there was a low sattellite notice. Probably due to us being chased out by a coming storm. So maybe my 1/4 is invalid and you can take me off the leaderboard. Odd that I did get a recorded 1/4 though.
Oh well, I will be back out next weekend weather permitting and will report updated results. Good thread!

Sometimes its not valid due to slope > -1 degree or low sats. You also can get anomalous results passing under bridges etc. No worries if u dont have the slips now just post up a screenshot like the ones above and I will edit as they start rolling in (prob will get a barage of them as winter breaks).The real world confirmation of performance mods is the exact reason i created this thread. We all like paper racing and dyno mastrubation (im guilty) but this thread is specifically here for street documentation.
Dont forget to also activate 60-130 to get the 100-200kph time. And make sure your slopes are less than 1 degree with good signal.

Car and Driver did 11.9 @ 120 mph with the manual GT4. Historically, all the PDK 718s have been 0.4s and 2 mph quicker in their quarter mile testing. Thus, I’m expecting them to hit 11.5 @ 122 mph (in ideal drag strip conditions at low altitude).

Well, before someone tells me to JRTFI's I didn't have them. Honest!.... I will learn though. Ours was a rushed affair. Dragy came in the night before, we drove to a safe spot and only got in 2 runs each before we ran from the rain. So, interesting about the slope, it was 7.85%.
Here is the data:

What is a good 60-30 time?

Dont know for the GT4, but just set 60-130 mph to be captured and afterwards you can switch your units to metric to see the 100-200 - it should be there. Look at the JCR times in the earlier posts. Re: 60-130mph, My R8 did it in 6.0 sec (under ideal conditions) and my Aston did it in 9.2 sec. I would say stock GT4 will be in the 10s.

Yes, very informative. I'm obviously not the most tech savvy guy but it's crazy how such an innocuous little box can provide so much data!
Again, thanks for setting this up. This should be a sticky!!

I think you mean 8s for the R8... but yeah GT4 will start with a 10. My 450 hp PDK 981 did it in 9.1s.

I have some preliminary data from the 718 but from a slower updating GPS source. And on track, in the rain, on winter tires in a slight bend with a 1% slope. But with nice fresh air for the engine. 10.8s. Which still isn't slow by any means.

looking forward to seeing your data! Good catch on the R8 typo. Ive done 6.8-6.9 multiple times in the winter but the v10 plus ran low-mid 7s all day even in the summer. That car was too fast for me to be honest. I cant even imagine the sambo tts monsters and mclarens that run 4s or the modded gtr that run 2s (i would throw up &#129314

Yeah I've not driven the R8 but I have the Lambo equivalent (in a journalistic capacity) and stuff like the Performante put in some silly times. Like 0 to 124 in 8.5s. It didn't feel that crazy to me because of the linear NA power delivery. Something with turbos feels a lot quicker still even doing the same times. Like the 992 Turbo S felt like a rocketship by comparison - also entirely useless power levels for the street. You just can't deploy it anywhere.

OK, I have a validated update. Went out to a secure spot yesterday to get some Dragy times. Didn't have quite enough room to run an 1/8 mile because of lack of run out, but great for the 0-60 test.
In short I ran multiple 3.75s so very consistent, with a few low 3.8's. I feel vindicated after my first run that didn't have the best conditions. The 3.7 matches Porsche's advertised claim for PDK cars performance to 60.
Question though. I notice the 1 foot roll out times of 3.5 seconds. I understand that most magazines use the 1' roll out, but have heard that "some" European manufactures don't. Is Porsche one of them. In any event I am very satisfied that my car meets 0=60 times as advertised. I'll get to the 1/8, 1000', and 1/4 mile times later in the week.

Leaderboard updated. Nice runs. It takes a violent launch to hit sub 4. If you can also program it to catch 50-130kph, 100-180kph (these two are custom measurements), and 100-200kph (built in but you need to activate 60-130mph to record it automatically) that would be great and we can start benchmarking with the manuals and european guys
