500whp in a c63 amg

What it needs to get close to 500whp or 60-130 in 8-8.5sec .
Easier to get with a car as have perfomance package?

Tune, long tube headers, no cats should yield to 460-480 rwhp. Ported heads you give you another 25-30 rwhp on top.

Or you can do a supercharger and yield crazy power

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

Here's the dyno that came with my car

'11 P31 with 23k miles, bought the car modded just not sure what all is on it yet. Any ideas? Sales guy said exhaust, intake, tune but I haven't had time to look under the car. Airboxes are carbon fiber if that helps?

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!

I am achieving over 500rwhp with long tubes, straight mids, euro air boxes, high flow filters, custom tuning, and a few other little bits and bites. And most importantly, high ethanol 94 octane gasoline.

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.

Hi, thanks for sharing. Would you mind posting or messaging me your specific mods? If you don't mind of course, if not I understand lots of racers like to keep their parts lists secrets so I get it. I'd just like to see what you have vs what I have when I find out what I have lol.

Hey guys silly question perhaps. But will headers void warranty? Can you pass emission in CA as well if need be? Is the car much much louder with headers? I have 2nd cats deleted and mikes H pipe.

Thanks

It may void your warranty, depends if the SA likes you or not.

No idea about emission, I doubt it will with no cats.

Yes, extremely loud. Not safe for people with kids.

Nice results!!

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

depends on what dyno and what fuel. for usa 93 octane
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.

I have AR LTH with xpipe and 3 inch cat back, ram air intakes and cf air boxes with high flow filters. Custom tuning . Light weight rotors and wheels for rotation mass and I'm at 470rw 435tq. My tuning is on point I log everything thru my zentronic system that's plugged to my exhaust . Tune and headers made 440rw. Stock 365. Dybo jet. 70° .fans not the greatest.

how are you guys getting to 500?

Don't worry about their dyno 440 rwhp. Remember how Jon used to say he has a factory freak? I don't believe his 440hp ever beat u.

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

What tuning are you on? We tune very aggressive compared to most (our stage 1 is 540CHP).

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.

I've been thinking the same. I made 426 whp on a 45 degree day with tune and filters. I doubt 500 is possible all motor without heads and cams. And I'm even at sea level...below sea level DA on cold days!

Im with you as well. 500 HP on a solid dyno is tough all motor on our cars.


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.

Do you prefer Husky and Petrol 94 over Shell 91?

Wouldnt touch husky with a 10 foot pole. It's garbage gas.

If I need 94, petro Canada. If only 91, then shell for sure.

Did you make any test that shows the C63 benefits from ethanol 94 octane? I didn't feel any increase in power instead getting lower mileage.

I definitely get a HP gain from ethanol enriched fuel. But my car has been tuned for it. Cars not tuned for ethanol often experience minor detonation, due to ethanol being more reactive, this is resolved by the car retarding timing via information from the knock sensors.

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.
