Performance Crankshaft Pulley for C55
Hi all --
Just thought I'd tell you about the latest mod to my C55. I started off with evosport under drive accessory pullies on my '05 C55 that I loved on my '99 C43. I liked these pullies as they added a little kick to these cars.
However, I found on these threads that someone was making lightened billet alluminum crank pulleys for the
C55 (www.abedinmotorsports.com) and I immediately bought one. Combined with my evosport pullies, that crank pully really unleashed the reving potential of my car. It now accellerates like crazy and so well (much better than before installation) from 60 to 90 that I leave most cars on the highway behind by at least 4 lengths before they realize what happened. 0-60 accelleration seems a bit better as well, but the main difference is that I can get the engine into the 5k rpm range much more quickly and at will than before installation and without as much noise or drama. This aluminum crank pulley (harmonic dampener) is the same diameter as the OE pulley so I was able to use the same belt supplied with my evosport kit (apparently, a longer belt than OE so as to decrease the rpm of the accessory pullies -- thanks Mertd93). Don't think this thing increased the hp of my engine but I do know that it certainly decreased the loss of hp between my engine and my wheels. Have yet to go for a dyno but I will certainly post the results when I do.
Later,

I'm glad you pulled the trigger on this crankshaft pulley, I was gonna try it myself but i was waiting for some feedback. Good to hear you can feel a difference. Did you install it yourself? Might want to check it out since you're in NY.

I had my mechanic friend install the pulley. I hear this is a fairly simple install from under the car -- should take less than 1 hour total. This is a butt dyno and engine usability upgrade -- I love it! Strange thing is, at normal acceleration my average mpg went from 17 to 19. No such improvement driving like a maniac.
Yes the AMS billet pulley is a full harmonic dampener with the appropriate rubber piece to absorb vibrations. The OE piece has been fraught with difficulities (at least on my C43). I definately consider the OE pulley to be a wear item.
Mertd93 -- pm me and we will exchange numbers.

Thanks for the write-up! I have been exchanging e-mails with Abedin Motorsports. Does anyone have detail installation instructions?

Hey Marc,
Thanks for blazing the trail with the AMS Crank Pulley. I've been toying with the idea of whether to go for just the UD Pulley Kit (from Vrus) or the UD Kit + Crank from AMS. Did you get a chance to do a Dyno? Those results would be a great help.
Thanks again for the info.

North 44: If I can escape unoticed from my wife I will get a dyno tomorrow or next Saturday. I think getting both the evo or Vrus and the AMS crank would be the best bet (but, I'm biased).
AMG Dude: install should be straight forward. The only problem is holding the crank pulley and being able to exert enough torque to loosen the one bolt holding the OE pulley and the securing the new pulley. Your mechanic should have the necessary tools. If not, search around, I seem to remeber a thread here, Club202 or MBWorld where harmonic dampner pulley replacement was discussed (same procedure).

Dyno Results.
All --
I had the dyno done, and need someone to post the dyno sheet for me. With the mods listed below the best 3 dyno runs of 5 are as follows:
HP: 308.12, TQ: 319.56
HP: 307.70, TQ: 319.43
HP: 306.04, TQ: 322.77
Done on a Dyno Jet at ICS in Stamford CT: 71.90 deg. f.; 29.64 in-Hg; Humidity 28%; SAE 0.99. (best run)
The dyno guy states his dyno is "stingy" and that the correct conversion from the above RWHP readings to Crank HP on an automatic for his dyno is 21% to 23%.
That means my best run showed max HP to be 400.15 at 23%, 390.02 at 21% and max TQ to be 419.18 at 23% and 408.56 at 21%.
The only unlisted engine mod. is Denso Iridium IK 22's.
Realistically, I am probably pushing 385 to 390 crank hp with the evo sport pulleys, AMS crank pulley, phenolic spacers & renntech CF airbox. (Note: I am running stock wires, the magnacor 8.55 mm wires didn't work for me). Next step: header, then quaife or renntech ecu.
The torque curve is flat above 300 lb-ft from 2.65k rpm to 5.25k rpm and the hp curve goes from 100 at 2.00k rpm to 308.12 at 5.75k rpm at a 45 degree angle.
(shoot me an email, I'll send you the dyno and then please post it in this thread).

Nice numbers
Did you do a BEFORE dyno to see what you gained from the pullies?
See yeah

But best of all, did anyone notice in the cut out pictures of the C63 showing the front the 63 engine as posted by a member on this forum, that the C63 itself uses the same kind of billet aluminum lightened crank shaft pulley as the one offered by AMS? See the AMG CLK 63 Black Series site, search around and click on "technical" to see a picture of the engine including the upgraded pulley: http://www.mercedes-amg.com/

I just looked at the pics, believe it or not thats the stock pulley, just looks aluminum b/c of the lighting, but thats what the OEM pulley looks like. No manufacuter will do this b/c the sheer costs alone are prohibative (remember at the end of the day they are out there to make $$).

pulley
Just wanted to share this with everyone. On Sat. i went to Countyline Dragway here in Miami and ran a time of 8.042 at 87.3mph track is 1/8 mile. These numbers were after i installed crank pulley and kleemann headers. Before this install it was running 8.478 at 85mph. I know it is hard to judge any differences with just track times but it was close to half a second difference so i think it is some what valid to say that between the crank pulley and headers there was a big change. Once again i do not know how much the pulley did but before the pulley i dynoed the car with the headers installed and headers gave me around 16rwhp. I personally think that 16rwhp will not drop a half a second at the track. All the setup was the same only thing that changed was first run w/o crank pulley and headers temp was at 78 and after install it was 75. Don't think it is much of a difference? Well hoplefully this helps.

Great news, good times. Just put Evosport headers on my car and want to take it for a dyno. Car is definately faster now with the pulley and the headers. Rather remarkable. It impressed the hell out my big displacement muscle car head of a mechanic.

Man, I would love to see just a straight up pre-pully dyno followed by a same day post-pulley dyno. Too many uncertainties for a guy like me. Headers, CF air box, underdrive pullies, just too many "could be this" factors. Don't get me wrong, you guys are doing more than 90% of us lumps sitting on our PCs.
I would think AMS would have nailed this data down from the begining. I would have. If AMS is interested in paying for the dyno I would have no problem using video to cover the pre/post dyno to confirm what the "pulley alone" makes.

Evosport makes headers now for the C55? When did they start doing this and how much do they cost?

Do you have pics of these headers? Are they a direct bolt on to your down pipes or do they need to be modified or changed?

They are a direct bolt on shorty header (see the Evosport web site picture of the E55 headers -- mine look exactly the same). No modifications or bending were required. You keep the OE down pipes and pre-cats. Apparently, they take a bit of time to install. My mechanic had to undo the motor mounts and jack the engine up a bit to gain enough clearance to install and torque the headers. Didn't have to do that to remove the OEM manifolds though. Will go get a dyno soon and will then learn to photo post and will post a picture of the post-AMS crank pulley dyno I discussed above and then post a post-AMS crank pulley and post-header dyno to see which part did what. The only previous mods were the Renntech airbox, Iridum plugs, Evosport u.d.p.'s and green filters. These could not account for more than a 7 to 10 hp gain at most. My Sprintboster only affects acceleration/driveability not torque or hp.

update
Hello to everyone just wanted to update the progress with the AMS crankpulley. After about 2 months with it installed and the car fully adapted with it feels great tons of torque off the hole. Even with the esp on it just breaks threw like it was on dyno mode and before it didn't do that. The thing that really caught my eye was the fuel. It was advertised to help in fuel milage but was skeptical about it and also wasn't to worried about it b/c this car was not meant to be a great mpg car. It really did make a difference in fuel cosumption. With the same trips on a daily basis the fuel last now from a week 1/2 bumped up to 2 weeks i was able to get about 3 or 4 extra days. I do not look much to the mpg thing on the dash because i don't know if that is accurate but my everyday traveling is accurate to me. Once again same trips nothing changed work and back home. So there you have it performance and save fuel thats great. If intrested for pulley contact Omey at AMS performance great guy. Hope that helps for anyone that was skeptical about the pulley like i was until i tried it for myself and was happy that i jumped on it.
