BROKEN SUPERCHARGER PULLEY DESTROYED my car!!!!
Here's the deal. All parts and tunes were purchased from Eurocharged, all installations done by RageTek, all dyno runs done on the same dyno during the same two month span with basically the same humidity and temperature. So any variables are out the window.
100% stock motor/tune with a CM30 pump and HE
411whp and 454wtq
ECU Dyno Tune by EC
444whp and 481wtq
added SC Pulley with Box Tune
451whp and 502wtq
added Kleemann headers with Box Tune
478whp and 515wtq
same mods with custom dyno tune
491whp and 525wtq
removed SC pulley with dyno tune
482whp and 510wtq
So there you have it.. I've posted various dyno graphs over the past 4 years to go along with these numbers. I've attended dyno days with some of the nastiest 55k's you'll ever see.
Don't come across like a veteran until you can bring more substance than a copy and paste from a vendors website.
By the way, nice jacket and pants...
Hey 10 year rotary engined veteran, two things:
1. Stock supercharger pulleys also lets go, mine did and shot a bearing out like a bullet toward my radiator, only stopped by the shrouds
2. MB probably spent a 100 times more dollars developing the stock pulley and stock intake than ANY aftermarket parts maker. Have you never wondered why a full aluminum pulley costs less than half of the plastic stock crap?
No worries. You're car looks great. I see you're also in a warm climate. If I were you, I'd throw a stock pulley back on the car and upgrade the throttle body. With headers, throttle body and a good tune, you can be very close to 500whp and you wont have to worry as much about pulley failures.
Another options is to grab a Kleemann or Renntech 168mm crank pulley and a meth kit for cooling.
My upper pulley also failed on me. Luckily it was at idle so nothing was damaged. That's why I ultimately went back to stock.




First, my man card:
Past 13 years as an MB dealership diagnostic tech. 7 years before that- Factory trained Ferrari tech. Before that- a self-taught car guy, I was drag racing down in S. Florida in my '71 Dodge Dart (gutted and rebuilt front to back by myself except for the paintwork) back when a lot of the guys on here were playing Playstation Final Fantasy on their mom's TV. I used to have a 5.0 emblem hanging from a noose on my rearview mirror. Killed them all on the street- and later the paxton/steeda crowd, laid to waste. My Dart ran a whopping 12.28 in full street trim..on street "legal" tires...and that was FAST back in the mid/late 90's. The only cars that would beat me on the street were those with nitrous, full tubbed big blocks, or trailer queens that couldn't drive 2 miles without overheating, or getting pulled over by the fuzz for no mufflers..and that SOB with a small block in a 280z...I would take him up to about 40mph then he would walk past me. I'd run into him every Saturday night it seemed! OK, nostalgia over..manhood proven hahaha..Oh, random fact about me: I also have my own Fire Truck.
Our intakes- damn good in stock form. Remember, this isn't an economy car we are trying to turn into a race car (aka Honda) Our air filters are basically double the surface area (hence two filters!) of your standard passenger car/V8 motor air filter. Look at our tiny throttle body vs the size of the air filters/box. Coincidentally, I've also dyno'd at Ragetek in S. Florida, and, I was the one to test the Needswings air intake that same day. I picked up around 6whp if I remember. And honestly, that could have been because the car cooled for 2 hours while I waited to get back on the dyno after swapping out my stock airbox.
Supercharger pulley...I always thought about 15-20 WHP. Nothing to back that up, just my guess, but the numbers you are seeing claimed for that pulley are the pulley PLUS the tune. So subtract the tune alone, from the claimed number and there you have it- the net gain from the pulley itself over stock.
My dyno numbers line up with FinanceMike, both at Ragetek's dyno and another Dynojet locally at a Mustang performance shop.
I also have around forty+ 1/4 mile passes in my E55 at 2 tracks here in Florida. I've learned a LOT about the E55 at the track, more specifically what is real-world and what is B.S. here on MBworld (and the internet in general) about what our E55's run at the track. Everyone (myself included!) posts their best times. So, my car is a solid mid-11's car at the track. But I don't post the few 12.00's and 12.10's I've run due to poor prep or scorching hot weather. And my times were all on drag radials. You'll hear the E55 runs 12.4 stock. Yes, it does..in the right weather at the right track. I've seen plenty running mid 13's stock too, because it was hot, or high 13's because it was hot and the car was running street tires with traction problems. Take all these E.T.'s with a grain of salt.
Some other findings that debunk some MBworld myths- The 82mm throttle body is worth about 25whp..and .1 sec and 1 mph in the quarter, that's it. If sure feels like more though. The 10hp=.1sec/1mph rule does NOT apply at these power levels. On a 14 second car, yes. The .1sec faster 60ft = .2sec faster E.T. does not jive either. .1 in the 60 ft. = .1 in the E.T. PERIOD! I have a stack of time slips to prove it. Weather!! Good one- I've found a good (approx) rule of thumb for our cars is= .1sec and 1mph in the quarter for each 10F ambient temp difference. Example, 11.50@122mph @ 60F = 11.70@120mph @ 80F. No wonder our cars feel like they have 100 more horsepower when the temps drop into the 40's here in Florida!!
Just remember, the gains on our cars which are already designed to make some serious power from the good AMG engineers, are small steps, as AMG did a real nice job maxing out performance with reliability!!
!
So that's about it- note: I am not attacking anyone, I'm really not a chest-puffer type, it's all in good fun, and giving back information to this community who I have learned so much from. ..and I'm up for some internet racing any day!! But I'm not sure if I'd buy a car from Timbershake...j/k!

Hahaha that's what's up my man, your making it happen!!! I'm happy to see experienced people on here

Even better, it can be done for $235. This is what I was going to do once crapmatic is out and coilovers are in.

but I guess I keep forgetting these beautiful machines we all own are practically maxed out and we're pushing them beyond the limits. I have to say I'm so proud to own this beautiful car, was just suprised about the pulley busting. But all in all, we have to "pay to play" 









Stock is too quiet for me...
