I see...well get it looked at, which shouldn't cost much. Hopefully nothing serious, these guys are giving good advice here.

It is very extremely rare that someone would not be impressed by the level of torque and power of the 55k engine. If you're not feeling that instant jolt of power and especially torque, then the car is definitely not running optimally.

As others have mentioned, the stock IC pump is not very good and is very popular for failing intermittently (in some cases without codes). If you check the pump and find that it's working fine, then there maybe something else more serious preventing the supercharger from engaging

LOL this bloody thread aint English

OP? You sure you aint got E320 ****-ant calipers/brakes

Umi...how much due diligence did you do before you bought this car? I don't care how much I love a car or think the price is too low to pass up...I'd still do a VIN check (at the very minimum) either via websites like Carfax (or the European equivalent) or even just through your local MB dealership to find out the work (warranty and non-warranty work done on the car).

Well that is enough of my high horse...

1. Invest in a CM30 pump.
2. Find an independent MB tech shop ASAP.
3. Heat soak will always be a problem with your car...an upgraded heat exchanger is a way to help...and is a must if you mod.

to be quite frank, I wasn't at all impressed by the Sl55 my father purchased. I know its a bit heavier, but I don't see what the fuss is all about.

not being impressed with the E55's power would be like pantsing Miranda Kerr (hot aussie model - look her up) and saying "meh Ive had better"

480bhp is not really anything crazy now a days.

A little OT here, but did you see tonight's 90210? Next week I'm going to watch with no audio

Love your sig BTW.

Cheers

Didnt catch it I'm afraid. The last time they screened that show (down here) was in the 90's when Luke Perry was in it (he was so cool back then )

Agreed

lol. Timing is everything. The new 90210 just finished when I logged on to the forum and saw your sig. I must say the writing/script has gone down the tube since the Luke Perry days and that is not saying much. But who is watching it for the script anyway

I had a '02 RUF 550 Rturbo and an '06 Porsche Cayenne Turbo S both with 550+hp and I was impressed when I drove my friends E55. What are you guys driving that makes an E55 not feel fast? 1000+hp vipers??

I have a 600ish whp awd dsm and have owned 700+ hp cars int he past. The e55 is still very impressive. Anyone that says they aren't is either named Jay Leno or Schumaker (spelling?)..

I have had 700whp Supras, 650whp Terminators, 500hp EVO's Z06's Vipers...ect My CLS55 impressed the hell out of me the first time i drove it and it still does.

I have a 700rwhp mustang, and as mentioned, the sl55 felt very flat. torquey down low, but thats about it. from a roll I thought a clk550 was pretty much the same in acceleration.

480bhp+4000lbs=meh

I feel that the E55 is really fast as standard, it will not be embarrassed by any other standard car including exotics such as Gallardo, F430 etc, (when it comes to speed/power).

To the OP, No standard Cosworth is as fast as the E55, I had a stage 3 saff myself.

Some of the guys have advised on what the problem may be, unfortunately here in the UK these cars are not popular so you need to be looking at finding a good specialist Mercedes garage or as a last resort, main dealer.

As for noise, they are not loud at all and bad fuel consumption is to be expected from a 5.4 ltr supercharged V8.

These engines are solid if maintained properly, check the history, @ 100k it should have lots, if not, change i/c pump and give it a full service, if that does not make a difference sell it and get a good one!

a good friend of mine drove mine (hammered it is more like it) and he said it was fast - his daily drivers are a SRT8 and a F-16 (still trying to drive the latter but for some odd reason the US govt wont allow it).
