E55 RUSS

Wetterauer Tuning for E55 Kompressor:

Stage 1 Chip

400 kW/544 hp at 6100 rpm
torque: 700 Nm at 2650 rpm 800 Nm at 2800 rpm
top speed: 250 km/h 300 km/h

Stage 2 - Chip and pullies

412 kW/560 hp at 6100 rpm
torque: 700 Nm at 2650 rpm 900 Nm at 2800 rpm
top speed: 250 km/h 310 km/h


Stage 3 - Chip, Pullies and Pressure Regulators


They say:

Stage 1 is done by software. We advance the timing maps and fuel delivery in the electronic engine control module. Additional we remove/modify the speed governor as desired. Also the wastegate timing is changed that we are holding more boost at high end.

In Stage 2 we add another pulley to the crank to generate more boost through slightly higher compressor rpm. That gives the necessary amount of air to increase the fuel quantity and produces 30 hp more.

If desired we also offer another kit with 590 hp with changed pressure regulators. The cost is Stage 2 and 1490 € on top for that.

All prices including installation and tax.

I wonder how reliable are their kits...

If it's possible to increase the POWER to 560 HP just with pullies and chip...

Why Kleemann is Headers to get the same HP??? Heat issues ???

and what do they mean by pressure regulators???

Vadim @ evosport

There is no wastegate on E55.

E55 RUSS

So they dont know what they are talking about...

Jakpro1

There is a Kompressor bypass valve though.....are they messing with that??

Anyway, my Kleemann Stage 2 runs 585 while Gid-e-ups ran 600.....and they don't even touch the wastegate.

E55 RUSS

Are you tailing about stage 3???

What is bad about if they are messing with Kompressor BY PASS Valve???

E55 RUSS

Another answer:

The boost is controlled by valves electronically. Therefore the ECU is able to close or open boostvalves even without changing the pulley.
The reliability is not an issue at all for our customer.
We like also to sell exhaust and metallic converters and so on, but we are specialized in power advancements, therefore you can choose any exhaust to attach to your car. It is true, that the heat is little bit increased in long term full throttle settings. But how often is that ?
Most customer want acceleration. That’s just for a few seconds. No more heat is generated by that. Heat is relevant if you drive hard like 1 hour at top speed. That is basically unusual.

Our warranty works just in the European community.

Can Drive 55

Isn't Gid running Stage 3?

E55 RUSS

Yes believe so...Stage 3 also includes on top of stage 2... Sport cats, middle and rear muffles and Sport CAMS...making 610 HP...

BUT lets not get

Vadim @ evosport

I have no idea about which valves they are talking about. Here are pictures that show and trace air flow into 55K engine.

The only way to increase boost is to increase kompressor speed. Period.

Jakpro1

Yes Gid is running Stage 3, but just like the awesome guys at EVO, Klee dyno's the car along each step to let you know how she is doing....she was pulling near 600hp before they put in the cam. Just trying to show that EVO and Klee stage 2's are not 560hp.

Thanks for the info Vad...as usual you are the man!

Can Drive 55

Hey Jak, I see you have now graduated from Jr. High. Must have been some photo that the mod censored. I didn't see it.

Can Drive 55

What am I thinking? Please excuse me M5. No more hijacking your thread. I will stay on topic.

pas

maybe someone can email these claims to Cory at Kleeman for his take on them?

E55 RUSS

OK...then how does MKB increase the BOOST from 0.9 to 1.0 with their stage 1 or stage 2???

With stage 2.. due less pressure in the exhausts...the boost drops from 0.9 to 0.7....and they bring it back to 0.9 or 1.0...

Notice...MKB uses pullies only in thier 620 HP stage 3!!!

for 595HP stages 2 they dont use pullies:

Increase in performance to 438 KW (595HP) at 5800 rpm, 765 Nm at 4190 rpm
modification:
high performance camshaft, exhaust headers s/s, adaptation of ECU inkl. Vmax delimiterter, sports air filters, shorter transmission ratio (I = 2,82), modified transmission control unit for a better acceleration rate, MKB optimized air intake duct

Vadim @ evosport

M5 RUS: Do not know, you will have to call them. What they are claiming makes no sense.

E55 RUSS

MKB has very good reputation as a Mercedes tuner...So it shoud make sense...

I thought Evosport is MKB dealer and should now how MKB does this ???

Wetterauer offers 544 with just a chip, MKB offers 540HP with chip and Air Duct intake...

Someone must know somethin about it...

WayneE

M5 RUS, are you familiar with the way a supercharger works? Think about what you're saying about Wetterauer - exactly how would they increase boost by playing with software?

E55 RUSS

No I dont know all the details...

If you read the post...I am not claiming anything...I just post what Wetterauer saying and know what MKB does...

MKB also increases the Boost from 0.9 to 1.0 with ECU...

Staff@RPM

I am not quite sure about this - the only way I see that being possible is with a Crank pulley like the Kleemann Stage 1, etc. They may have left it out, I sell MKB as well and they don't mention the crank pulley in their catalog at all. I believe it must be a misprint. As far as I know the boost must be increased physically via the pulleys, not through the ECU - that is basics on how a supercharger works. I personally recomend Kleemann products. As you will see from many others on this board as well, their products produce the HP numbers, are top quality and we have not had 1 problem with any of their items. That's not really biased because as you can see from my banner ad, I sell it all for MB.

Vadim @ evosport

I do not know how it is possible. ECU has no control over boost.

My guess someone in their marketing department is confusing 55Ks with turbo cars like Audis and so on.

E55 RUSS

H ave spoke with MKB Germany 20times about it...and that is no misprint...

Erik..if you sell MKB..perhaps you can find out from them..how do they do it???

silversurfer

Just a thought....

If you have spoken with MKB 20 times about it, why can't you find out how they do it? You've gotten responses from many people here (including two vendors) explaining that what you're saying is either incorrect or not possible. If you're interested in the product, maybe you should do the extra research needed to get your questions answered.

Good luck.

E55 RUSS

Thanks for smart answer....

MKB saying that they play with timing, ignition and something else...Its been at least 6 months ago...when they explained me this...

I just find hard to beleive that such tuner as MKB can say BS...

Someone must know the TRUTH

silversurfer

It's just not possible...you can't boost a supercharged car's HP numbers that significantly by reprogramming the ecu and playing with timing but not changing the pulley.

Maybe it's time to talk to Wett. and MKB directly to get an up to date explanation of their product.

E55 RUSS

OK...If this cant happend...then MKB is misleading thier customers???

I thought that tuners on this board, especially those who sells MKB products, would make this clear for US...

I find hard to beleive that such company as MKB would mislead their customers...
