ESIX3POWER

Can some one please confirm that the Horse power on the E55 From 2003-2006 is exactly the same for every year ? 469 HP A friend of mine is adamant that for the 06 year the Horse power was higher. True or false ?

hello and you should find your answer here

I could not access the link provided. Would you know if there is a difference in the HP ?

Thanks

Zod

As it states there is yes, later models been higher hp/more things added....not sure how you can not access the link

They are all about 500HP in reality. Some '03 cars have proven to be VERY strong and '06 cars have some ECU software updates that can make tuning a real challenge.

In the SL55, the very early '03 cars and late cars add larger throttle bodies that added another 25 or so HP.

Nice summation. Are you sure the '03 SL had an 80mm TB? I know the '07 SL55 got it, but thought that was the first OEM 80mmTB on a 55K.

At any rate, they are all around 505hp at the crank, and about 420hp at the wheel. I personally think the '03 and '04s are a little faster. It being software or hardware changes, I dunno.

my 03 is faster than my friends 06 when we race...both bone stock....except i have a cf lip!!

I am pretty sure that Victor verified an 80MM TB on an '03 SL55 and obtained one using the VIN from said car. I could be wrong but I am pretty sure that it was an '03.

jangy

Hmm, I never knew that. I knew the Maybach's had the 80mm TB that could be altered to work with the 55k, but that is all I really knew of.

I have an 03 and I ran a 416whp and 456 lb/ft of torque on a dynapack. If I'm not mistaken, Dynapacks do read a lil higher...so believe what you will...

vrus

Someone really pays attention!

You are 99.9% correct..

The 80mm TB was in production for 3short months on the 2002 BUILT 2003 SL55.. After 3 months of production they went to the current setup.

vrus

Oh yea... 1 more thing..

03 - 04 cars tend to dyno 10 - 15rwhp LESS than 05 - 06 cars. That was BEFORE the recall flash occured (which imposed the load limits in ECU).

I am not sure what the differences were after the load limits were put in place.

Yes, all the 55 kompressor engine models dyno very close to each other; about 420 whp on average (500 hp at the crank) despite Mercedes' claims of the SL/CL/S having more power than the E/CLS. Like Victor mentioned, some of the early 2003 SL55 models had the 80mm TB but the claimed hp numbers were not changed from 493 hp until the 2007 SL55, which was advertised with 510 hp.

05 E55's are the fastest. Just look on dragtimes Enzom for example.

jangy

Sweet!! Learn something new everyday. Wonder why MB went to an 80mm on the SL and then back? I wonder if they were phasing out the 80mm leftovers of the time? I'll do a part number cross check and price up. I doubt it, but the '03 SL55 80mmTB may be cheaper than the '07 SL55 TB or they may be the same.

skooby

I have an 2005 with new Michelin PS2's on it and nothing is coming close to me race wise.

Enzom's car is faster than ALL stock E55s. That car is on steroids

Enzom's car thinks it's an SLR

rflow306

I have seen other stock e55's run 12.00's- 116 to 117 + at Moroso under not so great conditions. So while Enzom's car is the fastest, these cars at the same track and conditions will run very close times imho.

Zod

to be honest i just think its the later models which ae better, just seems to be more 05's on the seen now, not sure if there is many 06, and if there were maybe owners not keen on hard core draging their car/lack the skill to get good results.
ofcourse this is all theory though

StealthAuto

Lol!~

enzom

I agree.

MB_Forever

I know. That's why I think that stock E63s will also be able to run very close times to Enzom's car if ran at that same track (at least within 0.1 to 0.2 seconds). When the E63 first came out, everybody said it was a 13 second car, and it was immediately discounted as slow because of a couple of runs. But now that people understand more about DA and weather conditions, and its effects on the car, more and more people are seeing the bigger picture.

Unfortunately, there is not nearly as many E63s on the road as there is E55s (4 years of production vs 1 or 2). Plus, sales back in 2003 and 2004 were at their peak while now they're very low. As a result, we're not seeing too many people driving the E63 let alone dragging it. This makes our E63 data sample very small compared to the E55.

Hopefully, Oldgixxer will upgrade his tires by his next track rental to PS2s and maybe go 275 on the width like Enzom's setup, and hopefully cut his time down by 0.2 seconds. And this should put him only 0.2 seconds away from the fastest E55 in the world

I have an '03 so I am obviously bias, but why should there be any difference from '03 to '06 when engine specifications and transmission are exactly the same? Oh, I just remembered '05 and '06 have 200 MPH speedo. That must explain the difference.

Natural variation among cars explains more than model year.
