    • Renntech W204 C63 Black Series M156 dynojet tune and baseline results - + ~15-19 wheel horsepower

      The C63 AMG Black Series is in a much higher state of tune than standard C63 AMG which should be obvious to most people. Renntech in SAE correction got a baseline of 434.4 and 436.7. The tuned numbers are 453.9, 452.8, and 451.2 on the three post tune dyno runs. This makes for gains just under and around 20 wheel horsepower on 93 octane pump gas. Logged temperature details are also included showing it was quite hot during these runs in the 90 degree range.

      In STD correction the peak rear wheel horsepower number goes to 463 tune only on 93 pump. Very nice and it also shows just how strong the C63 Black Series is in stock form with its 447 wheel horsepower baseline. The peak tuned numbers in STD correction correlate to what we saw posted from Velos Designwerks. Thankfully Renntech included both SAE and STD.

      Very nice work as always squeezing power out of what is an already aggressively tuned motor.

        Facts are facts, they ain't no stock C63 BS on the planet putting down 434 to the wheels, dyno must be broken.....PERIOD! Sticky, you can post all the graphs SAE or STD you want, I can read the entire post til I am blue in the face but it's not going to change the fact that an honest 434 to the wheels out of a bone ass stock C63 BS is impossible.

        LOL...you guys arguing over dynos and what appears to be about 15-20 whp. I've seen a stock '10 P31 C63 dyno 425 whp on a well known and reliable dynojet. SAE. MB obviously underrated the P31, many others have dyno'd about that whp. I don't see why it's so hard to believe a C63 BS could put down 434 whp. Doesn't it have a slightly different block design anyhow?

        I know they are arguing over a percentage that can be attributed to dyno variance, weather, and break in. I've seen M3's vary by 40 whp with their baselines.

        What facts? There are no facts posted to refute the fact the C63 dyno'd what it did.

        Honestly feel however you want about it, I'm not about to say Renntech is lying or inflating numbers for no reason as they never have and have no reason to. A higher baseline number also doesn't help them so it just makes no sense.

        I have a good amount of CLK Black Series and C63 Black Series dynojet run files in my inbox to sort through so we should have some more data to work with shortly to hopefully understand this topic a bit better.
