2006 CL55 AMG
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).

Keep in mind that FBO will get you to just around the 500whp mark. Any more than that you will need FI or N2O.

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?

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

17' C43 Coupe
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

maybe on a highway pull, but from a ditch donít underestimate 285 stock rears vs 255. That extra 3cm is quite a bit of extra traction.

and tuned w205 is putting out like 600 wheel isnít it?

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.

Yep the w204 sedan is lighter than the coupe because of the pano roof.

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.

A FBO W204 C63 will smoke all of those cars.

Cams are not worth the hassle. Throttle bodies can be upgraded. Theyíre all the same from the factory across the various models.

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.

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