MKB? Actually, Oberklasse is a shop in Texas that sells MKB- hence the Oberklasse stuff is MKB, not the other way around. EvoSport is also an authorized MKB dealer. We use their differentials in our upgrades.

Mr V.

How much improvement do you actually get when you upgrade the diff on a stock E55? How much hp gains and how much does it costs??


TIA!

I live in Northern California and I had my CLK430 shipped to Oberklasse in Texas. Among other things, they installed the E55 Hypertune kit and the 3.07 differential. My car sounds awesome and really performs. I have G-tech'd my car and pulled 0-60 in 4.6 in less than ideal conditions. The dyno on my car netted results that significantly exceeded the stock CLK55. Having raced a 55, I can tell you that numbers don't lie. I am switching from Brabus to BBS rims in the next week or so and am planning to dyno my car again after the switch. I am completely happy with the work that Oberklasse did and the performance of my car. You should know, however, that it is not a cheap process and you will get more hp with a supercharger... which I am planning to do as well. Nevertheless, I have no regrets and would be glad to give you more information if you are interested.

Are you keeping the 3.07 or going to a 3.27?

Sleestack, what is price for the diff change and what does the process entail?? I remember Simon telling me that it requires a remapping of your computer to adjust for the gear change??

Got any pics of your car and especially the engine?? And how much did the whole process cost you?? And how long did it take for the conversion??

Thanks!

Mach - I'm sticking with the 3.07. I think the 3.27 is too severe. I don't want to lose the power on the upper end, however, my opinion on that might change if I throw a Kleeman on top of my setup.

Vic - The pricing on the differential change is around $3500. I believe Evosport also does the differential using the MKB differential kit. I'm not exactly sure what they do, however, I can tell you that the net result is worth the money.

Jam - My wife loves that little cartoon you are running. I'll be posting pictures of my car (including the engine) after I switch from my 18" Brabus rims to 19" BBS LMs and after I install my Lorinser rear deck lid and trunk lip. Both should arrive in the next week or so. The conversion took a long time... 2 months with shipping. I live in NoCal and my car was shipped to Texas. I had the Hypertune kit, the differential kit, MKB sway bars, Bilstein shocks, charcoal ultrasuede headliner, and various exterior and interior upgrades installed. I have a spare E320 and V6Jetta to drive so I didn't mind the wait. The cost I would rather not disclose online because I negotiated a price with Oberklasse based on the extent of the work I was having done. I can tell you that I picked up my car with less than 1000 miles from a distressed seller for under $45K. At the time I was planning to buy a new CLK55 but I just couldn't pass up the deal. After doing all the work with Oberklasse, I ended up spending what I would have on a new 55.

Some people have asked me if I could do it all over again if I would just have slapped on a Kleeman.... my answer is no. I love what Oberklasse did with my car. Nevertheless, I am planning to put the Kleeman on top of the work I have already done because my need for speed is insatiable.

My father-in-law is waiting on his new SLR. When it arrives he has promised me his 500SEC. I plan on converting that car into a nasty luxury rocket cruiser.

Thanks for the cartoons! So on top of that you'll still slap on a Kleemann S/C on it?? Daaamn!! So i'm guesstimating you'll probably be putting out over 600+hp on the fly wheel once the Kleemann is installed right?? Daamn!!

BTW.. pls check your PM.

He's still a 4.3L engine. I'm guessing around 500HP.

Vic:
The EGS controller is changed to adjust shifting and more importantly, the ESP. If you change your diff without adjusting the ESP settings, you'll wind up with your "Happy Light" always flashing. --This is about all I know on differentials, besides they're sweet!

Yeah,

I'll be more than happy if I can get 500hp at the engine. 400hp at the wheel would please me greatly. I don't think the 55 even runs 600hp at the flywheel with a Kleeman installed. Anyway, given that I don't really bring my car to the track, all that power becomes moot beyond a certain point for street driving. Right now, I'm most interested in seeing how my car is going to drive with 19" BBS LMs and new Kleeman shocks.

Actually if you do Oberklasse conversion + the Kleemann S/C you might be able to attain past the 600hp mark??

BTW. Just checked out the Oberklasse site and... is that your CLK430?? Tell me it ain't so..??

:p :p

Yes it is, however, I can tell you that the hp number they posted is very conservative. The dyno's they ran on my car and my independent dyno have me pushing about 310hp at the rear wheel... with 36lb Brabus wheels.

One of the Kleemann customers i talked to back at Willow Springs who has an E55 had his pushing about 430/440rwhp and about 560/570 on the fly. I'm guessing the nos you have here is very good.

I'm not exactly sure what you mean. The numbers I have are rear wheel HP and Torque numbers. I'm not exactly sure how to convert those numbers to flywheel numbers. After I do the Kleeman, I'm hoping to get 400+ at the rear wheel. I can't really ask for much more out of my 4.3 liter.

All i'm saying is that you have some impressive nos there considering the stock HP is 275. But that will be something to see and experience once you combine that conversion plus the Kleemann S/C.

flywheel vs rear wheel hp

Sleestack

As a rule of thumb, there is approximately 15% loss of power through the drivetrain, which I guess is dissipated as heat, from the flywheel to the rear wheels. So if you ran your car on a chassis dyno with the rear wheels turning the drums and recorded 310hp, the flywheel hp would be about 310/0.85=365hp. I don't know how relevant wheel weights are .
