I contacted Kleemann HQ in Colorado Springs with a few questions about thier supercharger kit, how much it was for install etc. They said because I have the 7 speed I have to buy thier EMS module; this is seperate from the ECU and costs $2,200. I found this EMS module they speak of, but it was in with the supercharger kit for the new 4 valve engines.

Did any of you have to purchase this EMS module? It seems a little odd since this EMS is fairly new and I was told "The transmission would not shift at all without the EMS." and "It limits torque in first and reverse. Otherwise at the shift from first to second the cars computer would kill power." I guess all your supercharged cars are stuck in 1st gear then?

It may very well be beneficial to preserve the transmission, engine, etc, just want to learn more about it.

 

From my observation, the 7 g tranny will not be able to accommodate the extra power from the SC.

What is this EMS ? Is this a TCU upgrade ? I am suspecting the TCU has the torque limiter removed but nothing else. Do they offer tranny reinforcement?

 

Have you tried PMing addicted2speed or SLK 55 Kleemann ..... both of them have the Kleemann SC along with some other goodies!

 

Here is the EMS in question. It's a seperate module they install. From what I was told it's to protect the 7 speed and engine by limiting the torque. They said nothing about tranny reinforcment or TCU. Just this EMS thing.

Kleemann EMS

 

From Kleemann:
KLEEMANN EMS (KLEEMANN Engine Management System)

Cutting edge engine management technology - Sporty engine characteristics
The anti-clockwise rotating Roots type Kompressor is characterized by its unique ability to develop plenty of power at low boost pressure and this type of supercharger has proved its reliability and efficiency for many years. The new electronically controlled fuel injection and management system KLEEMANN EMS is on the other hand a technological break through.
The fuel injection and management system allows boost pressure to vary from 0,3 bar to 0,70 bar as the engine rotates up the rev scale. The electronically controlled, varying boost pressure ensures progressive and sporty engine characteristics known from naturally aspirated high performance engines. Increase in rpm results increase in increased power output all the way to up to the rev limiter. Furthermore the system ensures an effect curve without any bumps or valleys.
The EMS reduces boost pressure thus power output a fraction of a second before gearshifts to ensure smooth and gentle shifts.

Punch from idle - Flat torque curve remains intact
Like the earlier generations of KLEEMANN Kompressor solutions the new system still ensures plenty of torque from low revs thus a car fitted with the new system will have plenty of punch from rev levels just above idle. 90% of torque is present at 2000 rpm.

Safe, durable, reliable
The low boost pressure of just 0,30 - 0,70 bar makes the system safe and provides long-term durability for the engine. To further improve the safety aspect the EMS features a safety mode constantly monitoring the fuel - boost pressure ratio ensuring that the engine cannot run lean thus suffer damage to the engine. In other words the boost pressure and amount of fuel injected to the engine will always comply.
Even if the car is driven in an area of high altitude (less oxygen, low pressure) and down to sea level boost pressure and fuel supply adjusts automatically to protect the engine from running lean.

 

Interesting. I have 2 fuel pumps (not just 1) to handle the extra fuel load requirements. I also run ~96 octane to further help ensure I don't run too lean.

I have had zero problems with our tranny handling all the power & torque (I do not have this EMS).

-Matt

 

What? The EMS is for smoother shifting (although ours is not harsh/abrupt at all) - it's not that it can't handle the additional Hp/Tq.

 

Matt,

OK thanks for the info.

Let me rephrase my statement
It's my observation of one SLK 55 with SC. Might not apply to all.

Hmmm. You know of someone else's SLK55 with a Kleemann blower (or Renntech) that blew a 7 Spd tranny? Just curious - if so, it's the first I have heard of it happening. Whos was/is it (if you know)?

See ya,
-Matt

 

I'm no expert but isn't the 7 speed rated for 540 ft lbs of torque? The SLK with blower only puts out 480 ft lbs with stage 1 and 516 with stage 4, the current max. It should be ok then. The 63 with the 7 speed puts out 465 ft lbs which is right there with the stage 1's numbers. It should be safe one would think.

 

You need a separate kleemann ecu module with the kompressor, which controls A/F and transmission, among other things. I believe its about 2,000$ and the kompressor is about $14,500... which means you need around $16,500 minimum to add a supercharger to your car and have it working correctly.

 

According to Kleemann you don't need the ECU at all. The EMS module controls A/F and transmission. Kompressor is $10,000 and EMS is $2,200 + install. My drive away price for everything installed at Kleeman HQ is $14,000

 

Omg I strongly regret that I didnt bring my car to US for my Kleemann mods (Kompressor, EMS, Headers, LSD, cams, exhaust), I paid 40 000 US$ to Kleemann in Denmark for the whole package, 40 000 -14 000$= 26 000 for airticket, shipping and a lot of fun in US.
Why is it so expensive over here in Scandinavia? Its all about taxes
I pay about 3000$ in tax every month.

 

Anyone want to lone me $16,000?

 

Picked up my SLK from Kleemann in Denmark today, got a little bit more - from 513 hp to 535 hp and from 700 Nm to 735 Nm, and its smother, more torqe from the bottom, and it feels goooood The car feels smother, a true Mercedes.
I will add the exhaust soon, I have the same problem when the Kompressor was installed, shifting gear is a bit jumpy, but it will be better after some miles. Im pleased

 

The last dynotest after cams:

 

Congrats! That's a beast. Aside from the SLR/SLK, you may have the most powerful SLK that I'm aware of.

 

Yeah! i guess that I beat the SLR,

 

Kleemann's dyno's reverse calculate horsepower at the flywheel, not the rear wheels. Your SLK is likely putting down ~ 435 - 455 rwhp (assumes 15 - 19% drivetrain loss).

Kleemann calculates hp, not rwhp, because they advertise power at the flywheel (and back it up with dyno/software that proves it). Different cars have different drivetrain losses (5 Spd Auto vs 7 Spd Auto vs 6 Spd Mannual, etc so to avoid rwhp dyno disparity & keep it simple, they calculate flywheel Hp).

Question...have you got some wider rubber back there yet or are you still looking for rims/tires? Nice SLK BTW. Cheers.

-Matt

 

I thought he was measuring RWHP. Doesn't those numbers look too low for a supercharger and cams? I'm guessing he has a S8 right?

 

I have bought Kleemann TS-7, 10x19 and 8,5x19, and will add Toyo Proxes TR-1 on them soon, 275/30 and 235/35, so im still running with my original 18" wheels, not much rubber left . Also bought the Kleemann frontlip, have to paint it and put it on soon, my Kleemann exhaust system is waiting for me in Malmoe, I hope they phone me some day, and then I have every mods available for my SLK 55 engine, its a K4 not a S8.
True about the dynotest, but from 360 hp to 535 hp - Im pleased, the car is absolute a beast.

 

I'm planning on getting mine done next month as a birthday present to myself. It's not too wild and crazy is it? Drivability still good?

 

Excellent! You will have to post a pic for us when you get your rims/tires on Buddy.

Curious - what octane is available in Europe at the pump (ie Denmark/Sweden/Germany region)? Here in the US, you can buy 94 Octane (Sunoco), but not in California where only 91 octane is available (unless you buy 100 octane (race gas) - available at some pump stations...or 116 at the race track for cars running high boost turbo applications). Just curious - I have not been to that area in a while (northeast Europe) & was wondering what you can buy at the pump.

Dan my man, 535 Hp is HUGE power - especially with a 7 Spd tranny. Unless you run more blower boost w/higher octane, 535 Hp is pretty much the limit (and useless below 70 mph due to traction issues unless you run DRs, or maybe some R compound).

-Matt

 

My wife drives her SLK without issue. The car has significant torque & somewhat of a short wheelbase so you must be mindful of wheelspin - the car can rotate on you quickly (but if engaged, T/C will catch it - the wife always leaves T/C engaged when she drives).

 

I'm sure it is HUGE. For a sec though, I thought he had you beat. lol. I guess not. I still laugh thinking about you losing traction at 70+mph. That's not simply HUGE, but better described as SCARY.
