Okay it might be in the new E63 but at least it looks like it's possible without forced induction. The article is a snippet of the full one on worldcarfans.com

"Under the hood, VÄTH enlarged the cylinder head channels, installed new engine management software, and added new pistons, valves, sport cam shafts, a larger intake, and bigger exhaust valves (all for a whopping €19,635). Thanks to these modifications, the engine produces 605 hp and 690 Nm of torque (an increase of 87 hp and 60 Nm of torque). This allows the V63RS to accelerate from 0 to 100 km/h in 4.1 seconds, before topping out at 340 km/h (211 mph)"

yeah, VATH is doing a great job, dnt know whether it is available for C63

white_beast

Yeah we definitly needed for our light weight beast!!

the body shop manager at my MB dealer is into old school hot rods.

He thinks the 63 engine can go to 800hp

Guys,
Remember that number is FWHP(BHP) and not RWHP. There are C63's already at the 600FWHP(BHP) and haven't done any motor work. I believe with just bolt ons and cams they are capable of 650 to 700FWHP(BHP). Remember there is about 17-20% drivetrain loss. 605 less 20% is 484rwhp and some have already gone higher than that. These motors ARE monsters!!

Some folk(s) over at m3post would probably disagree with that. Sorry....couldn't resist.

What the hell are you talking about FWHP... FRONT WHEEL HORSEPOWER???? These are not Front Wheel Drive cars!!

Vath has completely rebuilt that motor, good luck getting that work done for anything less than $20k. Might as well just get a used 65.

What the HELL are you talikng about???? FWHP= FLY WHEEL HORSEPOWER. I would think that someone with 4500 posts and stats in his sig. that state RWHP number would be able to figure that out...... Oh wait nevermind I see what he drives.

Yeah I drive about $30k more car than you, not even counting the others in my stable. FWHP has always been Front Wheel Horsepower, not sure who you've been talking to. BHP, or Brake Horsepower is the measurement of pure engine horsepower without loss from the drivetrain or accessories.

cdd

I think that one could safely infer that he meant flywheel (bhp) from the context, but CH is definitely right on this one.

When I first read the post, I thought he meant front wheel as well...

Yes you did while using an entirely improper acronym in the process. Flywheel horsepower is BHP, now you know.

benscott01

Ok, so BHP or FWHP either way, you still made the complete DUMB *** assumption that the guy with "one" if not "the" fastest C63's would have actually thought his car is front wheel drive. Way to go you are now my hero.

Sincity, can I ask you an honest question? Why does the BMW group feel like the M3 is a faster and better car? I looked on dragtimes.com and none are below 11.41 and the quickest 60-130 on sixspeedonline.com (with the exception of 5.83 - RaceMX-M3 / Turbocharged E46 M3 / 1-shift) is 8.59. Both cars are equally fast when modified as much. Why does the M3 or M5 crowd feel like they need to come over here and tell us how slow we are?? I dont troll over on the M3post and tell them how their cars perform. Both cars are great cars and I like them both. Why can't we race and get along? There will always be a car faster than our own. Racing is fun and both cars run well.

AMS Performance

Crank HP is easiest

Sincity

I wholeheartedly agree with you. Both cars are great, and I too, wished that a mod from another forum did not do what he did.

Dads C63

They are also comparing a "supercharged" version to our N/A version. Whats up with that? I guess when the cams and stroker kit come out we will be more competitive.

Sincity

Ok. Let's cut the cowl, extend the front rails, widen the aprons and stuff a S65 motor into a C63. We'll go back to AMG roots and call it the "Hammer III" (that is if you consider the 190e AMG conversion as Hammer II). Talk about leveling the playing field.

No, I didn't, dip*****. I was pointing out the fact that the acronym in usage was ENTIRELY INCORRECT, as others have also said.

You're really not getting anywhere with this one.

MB_Forever

Assuming an 18% drivetrain loss, 605 hp would equate roughly to 496 wheel hp, which is not much at all for all the work done by VATH There are at least a couple of members on this board who reached numbers that were very close to those numbers with less intrusive mods. Jrcart hit 502 rwhp after his first round of upgrades at Evosport.

benscott01

No, you were poking your nose into a conversation that had nothng to do with you or your "stable", by nit-picking someones use of an acronym that as you and "others" have pointed out as being ENTIRELY INCORRECT. If it was so hard to understand, I'm more than certain you never would have understood it either. Maybe one day we will all have cars cool enough to hang with the big boys over in the bimmer world..... until then, we'l just keep out running them.

Stock for stock, you're not outrunning my M5. Second of all, if you really want to race, I can just bring out my rice burner and you can watch all seven hundred and ninety RWHP explode to the ground. The M5 gets me to and from work every day, and to dinner on the weekends.

Stop trying to make this a BMW vs. Benz thing. I've been a member of this forum far longer than you, and have always been a fan of benzes. The C63 crowd here regularly makes fools of themselves and this FWHP debacle has been no exception.

Dads C63

Wouldnt racing my little C63 against your 790 RWHP Supra be like bringing a knife to a gun fight?

Guys, we all understand the misinterpretation with the FWHP and BHP. Lets move on. The original topic was 605hp and we've covered that.

benscott01

First of all, once again nothing to do with the current topic "605hp from the 63 engine". We are clearly not talking about stock cars. And second of all, if i wanted to see your (and every other turbo-charged, NOS injected, highly over modded RICE BURNER explode to the ground, I'd run down to the local drag strip and watch just as many not explode to the ground, just plain explode internally and blow the motors....

I'm truly impressed with you being a member of an internet forum longer than me..... Once again has nothing to do with the topic. So anytime you want to run your "Pork Eating Crusader" we'll be ready

benscott01

I don't know, you still have to put that 790 RWHP to the ground..... Good luck.

Hans Delbruck

The AMG guys in Affalterbach have extracted over 700HP at the crank out of the M156 6.2l, without F/I. Learned that firsthand on my visit there in September.
