[Rematch] Modded E92 M3 DCT vs. Tuned C63 AMG +59whp!

I mean I'm just wondering. I comprehend the efficiency of the DCT but outperforming > 100 rwhp defiicit is a head scratcher. Cheers Ranger btw I know Curio that you are going to slam back. It was dyno tuned, baseline on a DD's was 342whp stoc, then 401 WHP with the tune, like Vic said, the C63 has the same motor as the E63 but comes from the factory with 50 less BHP, this tune basically gives you that and a little more, its' the real deal!

Just to add to that: The displacement, compression and bore and stroke are all identical in the 6.2 (not 6.3) liter Benz engines. MBenz plays games by controlling the output of the engine mostly via the ECU.

For example, the SL63 and S63 generate 518HP, the E63 generates 507HP, the C63 generates 451HP. I believe that there are also some minor exhaust diffferences. MBenz is concerned that customers would become upset by spending over $100K for an SL63 and having the same crank HP as a C63 for $70K!

The cars are basically heads-up now, eventhough the C63 has nearly 40 more WHP. DLSJ5's M3 DCT, primarily makes that difference up by weighing about 300 pounds less than the C63 and that awesome DCT tranny!

Very close race!
Is the C63 in stock form generally faster than the M3?

I dont get whats so surprising about the gains on the C63 it has a 6.2L motor that has to be good for something. I was there when they tuned that C63 and they got 342whp and looking at the dyno u can tell how the car was held back it look as if once the car hit 5000 rpm the power just stopped climbing and stayed flat like a shelf. Then after the tune it climbed all the way to redline and made 401whp. This was done on the same machine that I made 380whp after all my mods! and my Baseline was only 310whp lol those cars are beast so props to mercedes for that idea.

Great videos, thanks for sharing.

read somewhere MB limits the throttle body opening on the C63s to limit HP.. these tunes basically reprogram the ECU to open up the throttle body..

Uh, it is mostly software, the throttle body stuff you are thinking of is with the E55 vs. the other 55 AMG's which had larger throttle bodies.

That is a pretty big jump but not absolutely impossible especially from a big capacity V8 restricted from the factory. Is the dyno a little stingy, because 401 RWHP seems a little low for a estimated 507-518 flywheel engine. I wonder what kind of drivetrain loss the 7 speed auto has?

Its a Dyno Dynamics it doesnt get anymore stingy then that.

nice runs!

i was there when they tuned that beast too...

Nice runs! We just got our ECU back from EVOSport for our C63 last week! Might have to make some runs vs my M3 on pump!

Congrats.

Thanks Bro, with my current setup I haven't lost to another M3 yet, but did run even in one run vs. my buddies DCT, and he did not have a tune. We ran a about 5 times total on different days, I'd pull 1-2 cars, in two of the runs he had 20's on though. With more miles the car feels a bit faster as well, no doubt I will probably loose to another modded DCT, looking to run another one to see, Jon Martin's Modded 6MT and I ran very close as well.

I ran my buddies slightly modded DCT recently as well, here's the vid.

I would say the stock C63 and DCT M3 are pretty close stock.

That's what I was told as well from Jeremy at PC and Josh who owns the Stage 3 C63 that I ran in the vid posted here by 997slover, that's what 100whp more will do to you, Josh kicked my butt in that run!

I think he's right Bro!

Like JM said, it was on a DD's, on a Dynojet probably 435whp!

Atta boy Evan!! Love to see those runs. You should run him on pump a few times, then pump & Meth.

Damn that is crazy that C63 sounds more American than most American V8's! I am really curious to see how close a 3 way between a stock CTS-V, a tuned DCT M3 , and a tuned C63 would be.
