Ordered and installed NGK U5014 (R8) coils and replaced my worn out NGK BKR8EIX spark plugs. Also replaced cam follower after almost 5k miles, which evidently wasn't necessary as it came out literally intact, I was a little surprised I was expecting at least the DLC to be a little worn with my Autotech HPFP. Threw the new one in and gonna inspect in 10k miles. Also cleaned and polished the engine just a little using a damp cloth first, and then Autoglym's Vinyl and Rubber Care lotion for the finish. Don't expect to see professional work, tired as I was after working on the car
And did a DSG fluid and filter change, although for that I went to the dealer.
Here's the coils and spark plugs:
Couple more engine bay pics:
And went out for logging, thanks
queen :thumbsup: Primarily wanted to check for cf since I'm running aggressive settings and wanted to see if there was room for even more timing advance:
64F ambient, 80F IAT, top 2nd to top 4th about 7300 rpm but due to refresh rate vcds logged 7200. I didn't log overboost cause I wanted to see how it runs just like an ordinary pull on an ordinary day.
As we see here, the cf are acceptable for an engine running aggressive settings, considering you get 0 to 1 when running very safe. But you don't want to see values above 6 and especially if you want a DD car. So where I am at the moment is acceptable, but I doubt I can increase timing further at this point. Since my IAT is pretty good the bottleneck for more timing is fuel octane itself. I use pump gas only, 100 RON which is the US equivalent of 95 AKI, but for more timing without increasing cf I'm gonna have to use either race gas or w/m. I'm not gonna look for race gas and I'm not sure about w/m either, considering I'm now saving for my big turbo setup.
I'll update with another dyno after it gets a little colder, probably next month, because inside the dyno temps are nowhere near 64F.
