Is the Akrapovic Sports Cup a complete system from headers all the way down? Did the dealership say anything about the system regarding warranty? I'm assuming no?

Rob, is the F engine F 03048, similar to the E engine that was put in after the engine recall? If not, there should be another choice, one for replacement E engines and one for F engines up to F 03048. Does this make sense?

Good question bronson. I am under the impression that as far as the top end is concerned, there are no major differences between the E and early F engines. Most likely because it took that long to see the problem, devise a fix, and get that fix into production. Basically, I think you and I have E engines, at least as far as the finger follower wear issue is concerned. In any case, I don't think any serious attempts were made to fix the issue until engine F 03048.

That is my understanding. Someone please correct me if i am wrong.

Also, the early data we are collecting here shows that the top end change made after engine F 03048 did not in fact fix the issue. The DLC cam fix might have promise, but we need more data, and time. The first fix came in early 2015, the next in mid 2016. Curious to see if another fix to this issue shows up in 2017.

Bronson, another thing i find interesting is the range of outcomes. Some people have lots of miles, and plenty of track usage, with no issue. Others have less miles, minimal track time, and failures. I wonder why this is. Could heavy use of PDK Sport mode be the culprit? Is there a difference in oil used? Or maybe climate where the cars are driven is a factor. Understanding what the differences are could help people understand how susceptible their car is to the problem. Even track usage has tons of variables. The more experienced guys clearly track harder than the less experienced ones. They might even go to more demanding, and higher speed tracks. This group may have pushed these cars in a way that you or I would never do.

You see where I am going?

Rob i remember reading E engines were replaced with E1 engines then came F engines. Now, looks like you discovered F1. The F1 was followed by G then G1 or G2 (feel free to correct me if G1 or G2 is the latest).

I would think there is a difference between E1 and F otherwise why use a different letter.

Rob,
FYI, all my track miles except for a couple hundred early on were using PDK-S; oil & filter changes every 3,000 miles and low rpm warm up.

robmypro

They would have changed the letter with the new MY. So the change from E1 to F from a top end point of view is probably meaningless. I think we are on G1, assuming G was the start of MY 2016. That is why I am not distinguishing between F1 and G. I think it was the same engine.

robmypro

That's a lot of track miles without a failure. I am assuming you are very experienced, and push the car hard. What sort of ambient temps are we talking about, and what tracks are you on?

robmypro

Also, what exact oil are you running?

robmypro

We need to understand why we have these outcomes. Same engine, around the same mileage, yet one tracks the hell out of their car with no issues, while the other one has minimal track usage, and issues.

A couple of questions for you two:

1. What oil are you running? Mobil 1? 0w-40?
2. Are you doing any daily commute miles on the car in heavy stop and go traffic?

GT3 KSA

Also how often is oil being changed? I change mine every 5,000 KM and i use Motul 5w40
