Year C63 to mod to 500 rwhp
 

Hello fellow AMG ers. I've just came out of a fbo 500+ rwhp 700 lb/ft 2006 CL55 AMG wrecked by a cell/texter. The CL55, though an awesome sleeper, was heavy (4300 lbs.). Among its many attributes, what appealed to me most was the stout Kompressor V8 motor and two doors. Before leaping in to a 2005 CL65 (V12 TT) I've been eyeing, the prospect of the lighter two door C63. My central question is; aside from the 4.0 V8 Bi-Turbo, what year is best to push off in attaining 500+ rwhp? The platform prior to the bi-turbo is preferred. And yes, my 06 CL55 blew the doors off most American and Foreign muscle, including a 2017 C63S AMG sedan. Budget for initial purchase is up to $30k. Thank you.

2012-13 Black Series would be best. Second best would be a 2014-15 507 Coupe which has all of the best bits from throughout the production years. Third best would be any 2012-15 P31 Coupe with the forged internals (these are the only ones close to your budget).

Thx a bunch for suggestions. Will search for the 507, but what will it be called if surfing Autotrader, Cargurus, etc.? Does the P31 have forged internals?

Yes, P31 has forged internals.

How does the 6.2 litre stack up against the 4.0 V8 bi-turbo?

Stock for stock the 4.0 will beat the 6.2, tune vs tune the 4.0 will beat the 6.2. Now when it comes to the different stages of the 6.2 with the supercharger vs the 4.0 with the different stages im not sure who will come out on top but im pretty sure it will still be the 4.0. But Stage 3 4.0 vs stage 3 6.2 this is a toss up but i think this will go to the 6.2 as i believe some guys are in the 10.2 and the fastest 4.0 stage 3 i have seen is 10.7 (PL27 username) or better? but i could be wrong. I sure do love the 6.2 sound though, nothing like it.

Tuned W204 C63 should walk a stock W205 in a straight line

The new 4.0 turbo are simply faster and easier to get hp.

MY stage 3 6.2 runs 9.9 at over 140mph no c63s will catch that ( well not yet anyway)

Aside from the 204 bolt-ons, can 285 or 295 rear tire be had? Can it take a 100 shot nitrous?

Aren't the non-pano 4-doors a tad lighter than the coupes, since all coupes have pano roof?

I got 275 no fitment issue, no spacers. Add spacers, bigger rims, you're set. 205s are about 20k-30k more expensive. Add half that in mods to a w204 and it's game over w205.

Ah, I didn't see that he specified coupes!

Well, it should be noted that, all other things being equal, a sedan is (counter-intuitively) ~150 lbs lighter than a coupe.. If weight is an issue for you, of course.

MB Star Tekinfo shows curb weight for the Sedan is 3924 lb, the Coupe is 3935 lb.

Car and Driver has the specs for a 2014 base C63 coupe and sedan.

Coupe: 3816
Sedan: 3649

Base C63 + tune = cheapest way to get there

Thx you CL63 gang. Your responses and wisdom is very much appreciated. Will a 2012 bolt-on C63 hold it's own against a Stang 5.0, Camaro SS, Challenger 392, M3, M4? Aside from exhaust mods, are there cams and throttle bodies available to equal and/or best the 507? Thx you in advance.

Unibody Sedans are usually lighter than unibody coupes not just because of the pano roof. The coupe's B pillar sits farther back and the lack of door window frame compromises roll over protection therefore additional support is added to compensate for it.
Same with a convertible they are even heavier than coupes because of additional support.

Best example: Most of the e36 which are converted to track cars are sedans because of the lower weight and lower flex in the body.

LOL, this's awesome news
 

This's all i needed to know...assurance, lol Thx you

I think you missed the wheel hp part of OPs question. A tune won't get you anywhere close to 500 whp. . .

It will if you add those intake spacers.............(sarcasm)

Quit hating, those spacers are the ****.:cool:

LOL, intake spacers still are the smirk mod for the V8 Kompressor forums. Is there a large distance of Black Series vs standard C63; internals, etc.? Can a C63 be brought to Black Series specs then beyond?

Yes then No. Everyone who bought a base/cheap c63 argues that a tuned base c63 will surpass a pp c63. But then what happens when the pp gets a tune. It puts down more power than the base. Well, get headers on that base. So get headers on that pp. And the argument will continue. Slice it how you want, a pp car will always be at an advantage over the base if you stay stock or go mod for mod. By pp I'm talking about p31, edition 1, 507 and black series. BS has a lot more going on than just internals and a tune. If your goal is the 500 whp, why not give yourself a head start by getting the better engine.

The lightweight, forged internals make a difference. Rotational mass.

Mod for mod a P31 car will always be at advantage.

The black series has a better block

yea they could of just slapped a spacer under the air filter but gee they might know a few things about building engines lol

I'm so waiting for your TB results and debating still on sls intake.

How would one differentiate between a base and a P31?

There is a guy here in Cape Town running a 100 shot on his C63, and it hasn't had any issues.

Look up dads c63 I can't remember for sure but I think he was running everything from a 75 to a 200 shot

Let's try and leave that in 2017 :rolf:

The W204 pre facelift sedan isn't as light as some would expect. Mine weighed in at 3950lbs NA. I am in the final stages of running an ESS supercharger so that will definitely put it up over 4k pounds. Not exactly a lightweight

I plan on starting a new thread with my thoughts one I've had some seat time and when it is above freezing outside. I was not able to find much information on the kit either but ESS is big in other car communities. So far it seems like a very high quality kit. I have experience with the weistec kit on my last personal vehicle which was a clk55 and set the 1/4 Mile record and have put together several weistec supercharged E55s so I am familiar with their setup and customer service. The ESS kit cooling design is superior in my opinion due to the intercooler being on top instead of sandwiched between the supercharger and engine. The intercooler also looks much larger. They use the same Whipple 2.9L as weistec stage 3 at a much lower price point. So far their customer service has been better than what I'm used to. On time delivery and questions answered promptly. I don't want to get too off topic in here so I will start a thread when I have more info to share.

I too would love to know what you think about the ESS kit as, like you mentioned, it's the same 2.9L Whipple as Weistec at a lot lower price. I remember you did a lot of crazy stuff with that CLK55!

ESS is big in the BMW world and have a lot of high power cars out there.

With all the um, negative experiences I've been reading about with Weistec recently, I have been looking much more closely at mainly the Magnuson TVS2300 kit, and to a lesser extent the ESS 2.9L Whipple kit. There is absolutely no information out there that I can seem to find about the ESS kit though.

Who's tuning it?

Thanks. I will start a thread when I have more info. One down side is they use a 6 rib pulley setup for now. But if you're not building the motor for big boost that won't be an issue. After speaking with them they said they plan on releasing a bigger crank pulley and then a complete 8 rib pulley system for built motors. The kit comes with a tune from ESS.



I spoke with Magnuson at SEMA when I was doing my research. I wasn't finding much info on their kit either They told me they are moving away from the European market. That is what made me cross them off my list. I would like a company that is devoted to the platform. You should talk to each company prior to making a decision.

I finally hit 500whp to the wheels all NA! Followed the mod priorities on this forum and a little corn juice

Obviously the forged internals are a plus for weight and strength but the non performance cars without forged internals aren't anywhere near unsafe power level at 450 (tune)-500whp(fbo), are they?

LOL cast pistons are just as strong if not better then the forged internals in PP cars

These engines are build strong from the factory

Thanks.
