As previously posted, I have installed the C63 oil cooling upgrade (code 44O) a while back. Details including pictures of the parts and install can be found here:
https://mbworld.org/forums/c63-amg-w...ing-c63-5.html
Yesterday I took the car to Mid-Ohio for a full track day (with only 18 cars, so we got in a lot of track time).
The weather was sunny, temp. around 55 - 60 F. I drove the car hard as can be seen by the fact, that I burned 1.5 tanks of fuel (average fuel consumption on track was around 3 mpg ), the brake pads are gone and need to be replaced, and the rims got so hot, that I lost several balancing weights since the adhesive melted.
However, thermal health of engine was actually amazing! The highest oil temp I saw was 232 F all day. Engine temp was 194-197 consistently and the transmission oil peaked at 210 F (monitored via OBD dongle and Torque; it is normally at around 204 F).


Conclusion:
My C63 has no thermal issues whatsoever. I am convinced that even on a 100 F day, it will be just fine, given that it did not even break a sweat and has a huge margin to the 284 F or so where limp mode kicks in. One thing to note is that I have the BS front bumper, which allows somewhat more air in than the stock C63 - that probably helps a bit.


The main limitations on the car are now, in this order: 1. The operator , and 2. the brakes (which were still solid thermally all day, even with really thin pads).


I definitely need to learn how to be more gentle and smooth to reduce wear and tear. I also learned an interesting trick to keep the tire balancing weights on (aluminum tape).


All of you who knew about the track day and did not come: You missed a great and memorable day! Only 1 other Forum member actually showed up. That was actually pretty lame.


Finally: I love the header tune from MHP. The car goes like crazy - really, really strong. Andy from MHP was there also and showed his CLA45 with close to 500 hp - I was amazed by how fast yet still very driveable it is given the small 2 liter engine. No issues with turbo lag at least when you keep it moving on the track.

Great post Wobble, and glad the package worked out for you. Definitely on my list if I stay in the car long-term. Super jealous because I've had 2 trackdays cancelled this year already (Lime Rock and Pocono) - snow and ice really damaged the tracks out here this year.

What brake pads, rotors, brake fluid, and tires are you using? SS brake lines?

Wobble64

I have not done anything special with the brakes. They are stock 507, i.e. the PP 2-piece rotors and red calipers and stock fluid, one year old. They were rock solid, until close to the end when the pads got really thin. I barely made it home with very little pad left. Thinking about what pads to buy now.


Just had the car up on the lift. It looks like both the diff and tranny have had small oil leaks, as if they vented some. No stains on the garage floor though, so whatever leaked, did leak yesterday and stopped.


The Engine needed no oil, it still shows half between the min and max level.


I certainly got my 'fix'.

hi there where did you buy the upgrade from and how much was it??

Thanks for the update Wobble64. It is great to hear this cooling package functioned as advertised! I'm sold on the package now and will most likely do the upgrade soon.


It's also good to hear about the brakes. Sorry if I misquote here....But I think Diabolis mentioned that the MB Brake Fluid is very good compared to racing brake fluid: a very high boiling point. With the pads/rotors on the 507, multiple triple digits stops are not an issue in my experience. No fade and pedal feel stays consistent.


Thanks again for the write up. Happy motoring!

mr747,


see the above quoted thread - part numbers, price etc are all there on page 4. Here is a direct link

Regarding brakes, yes I am actually impressed with the stock brakes. With fresh fluid and good pads they are very robust. I just ordered stock pads again - when buying them at oediscountparts.com, they are actually cheaper than Porterfields = 238$ for a full set for the front. Maybe there are great Porterfield deals out there somewhere, but I saw them for 299$.
Glad I have matte black rims though - can't see the dust.

I guess you have you only ran brake easy tracks like Mid-Ohio?

Your temps are really impressive - I think we've got a winner here! Thanks for all the info.

Questions about tires - how much track time do you think you had today, what kind of tires were you running, and how much wear do you think it incurred?

Wobble64

I have experience so far on Laguna Seca (on AMG cars) and Mid-Ohio (my car). Both are ok with stock brakes. It is well possible, however, that other tracks would be more demanding. However, it became also very clear to me that it also depends a lot on how I drive - there is a huge difference between driving smooth and clean vs beating on it. The latter may not be faster.


I drove Yokohama Advan Neovas. 255 in front and 295 in the rear (Black Series fenders!). I probably did 150 - 200 miles on the track. My alignment seems pretty good, as there is no excessive wear inside or outside. The rears are getting close to the tread wear indicator, the fronts are maybe 30%. I had maybe 8,000 miles of mild commuting on the tires before. I think more width helps increase life.

Thanks for the update on your track day at Mid-Ohio, sounds like you had fun and the car held up well. If you are still interested in brake options, I see posts where a C63 owner has put the AMG Carbon Ceramic brakes on his car, only a spacer and 19' wheels are needed to fit them. It would be great if you could let us know how the cooling package worked on a hot summer track day where the temperatures are 80 degrees F or higher. I am thinking that the cooling package will really show its greatest benefit when outside temperatures are 80 degrees F and higher.

Bazman

Same here. Car went from limp modes every track day to none yesterday with the Package 440 installed. Temps reached 99C or 210F using all of the 570-580hp. Very happy.

colinamg

What was the outside temperature at the track?

Durban

unrelated question: how do you find out about track days? would love to go track my car but I have no idea when the events are, or when events that I could actually drive in are...

colinamg

I live in So. Cal. and have been going to speeddistrict events. There is also speed ventures and many other clubs. Just google the names above and the websites have all the info you need. It would be great to see more AMG's at these events.

Going to Watkins Glen with these guys Mon-Tue. They have a bunch of great events.

10 10ths is another organization that organizes track events.
