GT3 engine break-in
With apologies to all since I'm sure this has been covered in full. I'm not very fascile with the forum search function and wasn't able to find anything. I was lucky enough to secure a 2018 touring and am just short of 500 miles now. My memory (from lurking for 2 plus years with scant hope of getting a build) was that 1000 miles spent below 4000 rpm was considered adequate for this engine. But looking at some info from Porsche, which may be generic for all 911's, it seems they recommend 2000 miles. Any links to established threads or advice is greatly appreciated! Pics to follow in the touring and car/motorcycle threads.

0-1000 miles is fine |

Outstanding - thanks. Looks like I can push the revs a bit higher well..

From 500 to 1000 I would push to 6000 From 1000 to 1500 up to 7000 At 1500 drive it like you stole her |
This should make it clear;
Porsche GT boss Andreas Preuninger on Porsche break-in, during a video presentation in Autumn 2015, as reported by someone on Rennlist (https://rennlist.com/forums/gt4/90228...e-rules.html): "I videoed AP's presentation, and here is what he said: «I can only tell you how I personally do it, or how we do it at Weissach – for the first 500 kilometres or 300 miles, we don’t drive that car car ever over 5000 rpm, never. From then on, every 200 kilometres, we up the rpms by 500, so we end up at 1300, 1400 kilometres at the threshold before we can really go full throttle, at 800 or 900 miles.» He then went on that this procedure was really important for the GT3 RS engines given their more «delicate» rings - and how important this break in really is for any of their engines. Another point - he recommended to realign the car after 1000-1500 miles due to settling - especially since the tires are getting bigger and bigger, and more sensitive to changes. The RS apparently is really sensitive around this. You figure the head of the GT program would give you the straight goods." |

Reading, researching, and breaking in many cars, I say best is to be gentle, but push the engine up to 4k rpm and possibly higher for the gt cars. I subscribe to the idea that babying the engine too much or going crazy with it right at the beginning, may not be the smartest thing to do. Make sure to warm the engine above 190 F before pushing it. Think this latter part is important. |
Thanks to all - super helpful. Other than a few tire spinning overly revvy moments getting out of my slick driveway I think the break in has been at an appropriate pace. Here's the beast. It's Carmine but perhaps looks a little Guards red due to the lighting.

Beautiful color...and love those Silver (Satin Aluminum?) wheels with ceramic brakes!

Satin. It's crazy how the lighting affects these colors. I dig the white as well and am familiar with your car having followed all of the GT3T threads on here for what seems like an eternity!

Looks like we just get generic 911 break in instructions. One commonality appears to be the 4k RPM limit for the turbo charged cars (ie 991.2 911 and GT@RS).
Perhaps someone here has access to a 991.1 911S or GTS manual for comparison |
Im still surprised they dont bed the brakes at the factory. 500 miles is my personal rule. 2k miles of normal driving seems impossible to me in a gt3rs |
