500whp in a c63 amg
Performance Package dont give u really a higher overall Engine power...but your Engine revs better to high rpms because the Engine internals are from SLS.
Facelift pro:
No headbolt problems (Engine Number must be higher than 060658)
With PP better engine revving
Interior Looks more quality
Faster shifting gearbox (mct)
Facelift contra :
Heat Problems under the hood because of the Facelift front bumper (smaller air intakes)
In Germany i know some e63/sl63 with mct which have gearbox problems
Shifting isnt smooth as pre Facelift with converter gearbox

Drove a stock C63 and this one is no question stronger. First MB so please help a brother out. Former Boss302 owner and while I thought the Ford Coyote V8 was strong (did heads, cams, AR LTs and tune), this car would destroy it!


The one you bought that is over 500 probably has the same mods. The progression path on these cars is fairly linear in terms of required items:power gains.

No idea about emission, I doubt it will with no cats.
Yes, extremely loud. Not safe for people with kids.
We have 98 unleaded here (like the USA 93) and I'm at 458rwhp with stock exhaust. As it was ex UK, I already have the OEM Euro airboxs and filters.
Race headers and higher flow exhaust I can see getting me to around 480rw, maybe a bit more. I think that another point in octane might be needed to touch 500rw, I'll know soon enough
500whp on a mustang dyno you'll need a supercharger
500whp on dyno dynamics, improperly calibrated dynojet etc... headers/tune/air filters.
if you have like 98 octane and a badass tuner 500whp on a mustang may happen.
how are you guys getting to 500?

I am at 435rwhp with tune and filters. Some of these numbers seem high

it seems that peoples numbers are so heavily dependent on whom made the dyno. Don't forget altitude (air density) plays a huge factor on NA power output. We use a Dynocom Dyno, and have somewhat thin air up here in Calgary. I definitely feel the difference when I'm driving somewhere like Vancouver with very dense air.

Im at 465 / 405 LB FT TQ. AP LTH / Renntech Itakes + AFE Pro Dry Filters / HFC's / Eisenmann Catback and Modified V5 tune from Eurocharged.
All my dyno pulls are from the same shop / Dyno Dynamics machine. I went as far as to dyno the car after every subsequent mod, just to see what kid of power each addition made.
My baseline was 385 WHP, after Tune it was around 425 after headers it was 465. Dyno's are worthless, My car read 420 WHP stock on a dyno dynamics machine, but pulled 385 WHP on the Eurocharged dyno dynamics dyno.
There are also the options crank pulleys and throttle bodies, but for that kind of coin, I might as well super charge the car.
I'm not sure how some of you guys are doing 500+ all motor on our cars without tearing the engine down and going ported heads / cams etc.

On the flip side, my car runs somewhat poor on 91 (often backfiring hard). I learned this when I went on a road trip and only 91 was available, and it was off brand mystery gas.
