Let's talk mods.
Renntech seems to offer a decent mod (ecu & pully), what other, reasonably priced mods are available?
EVO is supposed to come out with an ecu & pully upgrade, is evo a reliable company for such products? (No offense to the guy's at evo). Would you go with EVO or Renntech?
Is a differential mod available?
Can the car be lowered by manipulating the electronic suspension control?
Can the sport suspension settings be made even stiffer?
What is the deal with Nitrous? I always see it on japanesse imports, is it a practical upgrade for an E55?
I'm also think of getting these Lorinser front fenders, I would not get the side skirts or rest of the kit.
What do you think of these fenders?

NOS sprayed directly on the intercooler heat exchanger would be good for some ponies. I think it is 1% power gain for every 10 degree reduction in temp. I don't know if I'd do a direct injection dry NOS system but there is probably no reason you couldn't get one of their wet systems that will piggyback on the stock injectors. You could pick up another few hundred ponies with a good NOS wet system.
Have you met someone quicker on the street than your 211 E55? The only quicker 4 door car out there is the S600. New tires and a chip upgrade will get you in the mid 11's in the 1/4. The new 211's are running low 12's at the track, right?

Rave E55- I think that Renntech is a very good company and you can't go wrong by doing their chip and pulley upgrade. Evosport is also a very good company and you can't go wrong with them either. I think by getting a pulley and chip upgrade, and swapping tires (what tires come stock with E55?) your car will be absolutely unbeleivable!! I would suggest not going with NOS as I have heard some horror stories about it. One slip-up and you can be dead!! A board member (can't remember his name) had his car lowered by having the dealer tweak his ECU. The drop looks great and he says the car handles much better now.
My vote goes for upgraded tires, chip and pulley upgrade, and ECU lowering, you will be a monster then!!

Thanks,
I already changed the rims and tires, I have 19's with 285's in the rear.
I'm leaning towards the Renntech mods, I just want to see what EVO comes up with.

im in on some mods but $5,000 for 40 hp through renntech seems a bit steep. on my c32 i had vadim and those guys at evosport were on that board all the time. inever see them post here. i wish they would update more. powerchip has a chip for 1200 that gets you to 489ish with a chip alone.

I've been told by people who have dynoed stock E55's back to back on the same dyno as a new SL55 that they both dyno with the exact same hp. The new E55's have the same power as the SL55's even though Mercedes rates the SL55's higher. I'd bet it is a marketing ploy to sell more SL55's? I guess they want the SL55 owners to feel superior since they had to ante up so much more money.
Don't take any tuners word for performance. Make them gurantee their performance on a dyno. Many things will actually reduce hp when they are supposed to improve hp. You don't want to go backwards when you are trying to go forward and the only way to really know if your mods worked is to take it across a DynoJet or some other reputable independent dyno shop. Once again, make them give you a written guarantee that can be tested at an independent dyno shop. If they will not give you any guarantees, take your money and walk away.

I went the RENNtech route---great improvement. I would recommend it.
What about exhaust mods? The options from range from a full exhaust change to just changing the mufflers(silencers). I am leaning toward just changing out the mufflers--the stock exhuast system is not bad---and an entirely new exhaust system is several thousand dollars--for at most 15-20 horses.

Check out a prior thread about RENNtech mods--has more detail. I went the ECU and Pulley route. Was not able to do a dyno--see prior threads about this as well---however,--I saw some dyno reports on SL55's(same set up) and my seat of the pants feel confirmed the improvement for me. The price was $5K plus installation. If you think this is bad--check out the price of Dinan mods. I have had around 1200 enjoyable miles since the mod--and it runs beautifully. I would like a little more exhaust sound---and as I said before, I am checking out what is available. Supposedly RENNtech is going some sport mufflers soon.

I would also like to know who has has a couple of 211 E55's on a dyno in the US. Everyone that I know that has tried has had issues including myself. Any thoughts would be very helpful. It would seem that the US ECU has a serious issue with the Dyno.
Thanks

Not a bad time given the temp, humidity and street tires, I doubt stock s600 in the same conditions would have done much better.

Ya think the E55 is faster than the S600's?

This S600 now with a Renntech chip upgrade runs regularly at 11.6-11.8 @ 118-119 in the 1/4.

On those 11 sec runs he was using drag radials - FYI

No, I don't think the E55 is faster---my point however, is that the 1/4 mile times would likely be much closer than 12.7 and 11.7 assuming you had a similarly modded E55 (ECU and Pulley--sports mufflers and drag radials) and similar altitude and weather.

I'm going with the Renntech ecu / pully upgrade, sending in the ecu on Monday.
Does anyone know of a good shop in the NY area to install the pully?
The jury is still out on the Lorinser fenders, come on guy's give me your opinion.

"Right..and imagine the E55 with the same mods and the car is lighter."
O.K. That S600 has a chip upgrade. Get a new chip in an E55 and it still will not touch that car. Get a chip and a pulley - still will not beat that S600 in a drag race.
The S600's stats on street tires:
With RENNtech ECU and 275/40-18 Potenza S02A rear tires: 522 RWHP, 660 RWTQ, 11.99 @ 117.0
Here are the renntech chip and pulley upgrades on an SL55:
http://www.mbautowerks.com/performance/00010/00010.html
The E55 with mods would still be almost 80 RWHP and 171.9 RWTQ less than the S600. The torque and horspower difference is huge even with the weight difference. I'm a big fan of the E55 too but the S600 twin turbo is king of the Mercedes line in drag racing. Twisties, well, that is a different story.

.............I am glad someone brought up the issue. I have been researching the S600 since someone here locally ordered one. Initially, I was wondering why he would do that instead of buying S55. It turns out the actual fastest production MB may not be Sl55 or E55 but S600. Unfortunately, there are not too many of them around to test. I believe car and Driver tested S600 vs BMW 12 cylinder counterpart. The stock S600 did a 0-60 in 4.3 secs. Of course at twice the price of the E55, I'll still go with an E55.

I love watching those videos---that S600 is damn fast---truly the ultimate sleeper. Sooner or later, someone on this board is going to run a modded E55--in cool dry air---like nighttime in Sacramento---and we will see
