I've owned my 2017 C63 Coupe for a little over 2 years now and hadn't taken it to the track yet. The weather forecast on Friday looked like it was going to be a great night to go to the track and make some passes, so I made the 2 hour drive in rush hour traffic from Miami to Palm Beach International Raceway. Got there around 8:00 p.m. and it was packed for test and tune night. Got through tech and got into the staging lanes then waited.

Unfortunately, there were a lot of breakdowns on the track so I only managed to get two passes in between 8:00 and midnight due to all the down time. The first pass was my best of the night and faster than I expected to go given the car is a non-S model and bone stock down to the paper air filters. All I have done to it was install MP4S tires all around (275/35/19 F and 305/30/19 rear) a little over a year ago and change the plugs a couple weeks ago.

The slip, video and Dragy data are below:





I was pleased to see that the Dragy numbers were very close to the numbers on the timeslip. Especially since PBIR is being sold to a company that is going to turn the entire facility into a distribution center and this winter racing season will be its last.

Temperature was about 67 degrees farenheit on that run, but it was pretty humid with a lot of moisture in the air. I had everything in Sport+ mode, used race start and let the car shift itself. I set rear tire pressure to 35 psi. The track prep at this point of the night was good and the car hooked and took off. Here is the 0-60 mph data from the Dragy on that run.



Unfortunately, I was only able to make one more pass and I was the very last run of the night. I was going to manually shift on this pass with the car in comfort suspension mode but I engaged launch control too soon and it caused a terrible start, then spun badly with the traction control off and the track prep being pretty much gone by then. Ended up being a 12.21 @ 116.42 mph with a 2.025 60'.

All-in-all I'm happy with how the car performed and I'm looking forward to getting the mods started.

 

Nice run! Very nice to see how accurate the dragy is.

 

Yeah, that was the highlight of the night considering how few runs I was able get in. I just need to find a secluded area closer to me so I can test out future modifications. No easy task where I live, though.

 

nice runs. good for base c63. i love seeing the dragy strip comparisons. it really is accurate. I too have found that it is slightly slower than the strip. I also have found a secluded area near me. no waiting in line for 2 runs haha.

 

Tell me about it. I was reminded as to why I stopped going to test and tune nights all those years ago. Glad I was able to confirm the Dragy is accurate enough that I can test out future mods without the need to waste an entire evening getting to a track (although the track surface is better prepped for testing acceleration from a standstill).
