So I just got a new-to-me 981 Cayman S and decided to see what it could do from a dig.

A little background, I have a 997 turbo that's tuned to about 600HP, so I have a vbox to see real-world changes to the mods I make.. for the turbo, it's all 60-100 and 60-130, etc. My turbo is a manual, and I can honestly say I have never done a super hard launch in it because I really don't want to abuse the clutch. That car is not a dragster.. Now once you get up to a little speed, it's a rocket!

Anyway, I thought I'd throw the vbox into the Cayman and see what it does.. For those who don't know, a vbox is a professional performance measurement device that is about the size of a large cell phone and sits on your windshield like a radar detector.. Most of the major car publications use it when performance testing cars. It's pretty darn accurate. I did two launches and kept the best one, really this is a novelty and I probably wont be doing it again as I'm sure it's not easy on the PDK. (Yes, I saw the video of the guy in a 991 turbo S do 50 launches in a row..)

This is my first PDK, so doing the whole launch control thing was odd at first. Not natural to have your foot on the brake and gas at the same time.. Regardless, these times are for a stock 2014 Cayman S, w/ sport chrono, 22K miles, on 20" wheels, outside temp was 54F, tires are fairly new MPSS, tire pressure was 30psi all around.. I did get some tire slip on the launches, so there are probably better times to be had in the right conditions (tire pressure, tire temp, etc.) if you can get it to hook up at the start.

From what I understand, when MOST magazines quote 0-60 times, they include what is called a 1-ft rollout, which basically means the clock starts after the car moves 1 foot. Honestly I'm not sure how Porsche measures it, but my vbox captures both with and without 1-ft rollout. Anyone know what the quoted times from Porsche are?

First is 0-60mph w/ 1-ft rollout, impressive time of 4.1s



Below is 0-100kph w/ 1-ft rollout..




Below is 0-60mph (no rollout allowed), not bad at 4.4s


Finally, below is 0-100kph (no rollout allowed)



I gotta say, this car is a hoot to drive.. I am really liking the PDK, the way it shifts up/down and the sound with the PSE is glorious! And it is super rev-happy which is also completely different from my turbo.. And having a semi-modern tech in the PCM3.1 is also cool!

Sweet looking car. What wheels do you have?

I have a 2016 981 Boxster S with PDK. Using my VBOX HD2 from a standing start, in Sport Plus mode but not using launch control, just planting my right foot all the way to the downshift detent (but not actuating the detent), I get 4.70 sec. zero to 60 MPH as indicated on the data trace. This would be equivalent to your "no 1 foot roll out" run. Never tried with launch control. I had MPS-S4 tires on the car at the time. Outside temps were around 48 F. Had quite a bit of tire slip at the start but let PSM do it's thing and kept the pedal down.

OP, great color choice on your CS

Okie981,
4.7 is pretty impressive. I assume that's the 3.4L flat 6? Rated at 330 HP?
When I got my new-to-me 2010 BS, I did some digging around for perf stats and found the info below (including the 981 series info below).

From: en.wikipedia.org/wiki/Porsche_Boxster/Cayman
Boxster 981 model history
Year ....Engine and Power (PS / bhp) (N.m / lb.ft)... Transmission... 0–100 / 60 (k/m)
2014..... 3.4L 243 kW (330 / 326). (370 / 273) ...........Manual (6) .........5.0 /
........................................................................ ...............PDK (7) ...........4.7 / <<<== Just what you found!

The engine appearantly was the same from 2014 thru 2015 and into 2016; the turbo 4 came at the end of 2016. Also, the Spyder had the 3.8L starting in 2015.
The data goes on to show you'd probably shave another 1 or 2 tenths by using Launch Control.
Nice!

Very cool, thanks for sharing that! Did I miss what your 0-60 times were for your turbo?

The 3.4L NA 6 is truly a gem and I think it is very underrated. The smaller size makes it a very rev happy engine that pulls hard from 3500 RPM to redline. Years from now I think it will be highly coveted for these reasons.

Yes, it is the 3.4L flat 6. Actually I think the OEM rating on the 981 Boxster S is 315 HP and the Cayman S is a little higher. My car has Cargraphic headers installed, did not mention that in my earlier post.....
