Who here on the forum has made the most horse power (naturally aspirated) with what mods? thanks everyone

t-boy

Hello,
I am new to the forum and have a 01 E55. I had my first runs with it this weekend (what fun) but could only get a 13.83 at 102mph. I am looking also for some cheaper, easier ways to improve my time.
Thanks

Actually ... that's about right for stock, unmodified, depending upon altitude and temperature.

My 99 55 put out 285hp at the wheels and 297tq. I added K&N intakes, Evo lightened pullies, exhaust and PowerChip. At the end of all this I ended up with 310hp and 324tq at the wheels, not bad.

Now, I removed the Powerchip and added an HPS supercharger. Having a supercharged car is way more fun. I'm guessing I'm putting down about 360whp, but I'm still doing some more mods to get the HP's closer to 400whp

Please contact me if you have more questions.

Though if previous gen CLK55's are hitting 13.2 - 13.5, shouldn't the E55 be a few tenths lower? 300 or so pounds shouldn't take as much as a 1/2 second hit, should it? (I have a vested interest in this thread as I'm running a motor from a 2001 E55... )

The 208 Clk 55 had less HP and Tq than the 210 E55's. I'm sure the only difference is software. I'm guessing MB tuned the CLK down so that the 0-60 and 1/4 mile times would be close between the CLK and E.

Not n/a but FI. Putting down over 500+rwhp. Minor mods. :v

^^"minor mods" LOL

^^ They are minor. :p lol

Have any of you guys broken into the 12's??

13.5 @ 103mph here 3 weeks ago. Stock down to the paper filters which I just swapped out for K&N's last night. Dealer didn't replace my paper filters at the last service - needless to say I'm not happy. Car is a little snappier with the K&N's.

Anyway, with stickier summer tires I'm hoping to get it down to 13.2 or better. I had to drive the car off the line with my Pilot Sports, it would not take any brake torquing at launch without spinning. Best 60' was 1.9x so there's room for improvement.

I wouldn't waste time on pulleys, etc. they really won't net you much at the track. There aren't a lot of mods for this car that aren't major, i.e. supercharger or increased displacement.

How can I improve my time a little with a few thousand. I am considering Renntech and a ECU upgrade and carbon air filter (?) Anyone with experience with this or thoughts. I want to try to keep a smooth running car... it is a Mercedes still.

t-boy

13.5 is a nice run. How many miles does your car have on it? Also can you explain more about the K&N filter? Is it easy to install?
Thanks

That's a bit high IMO.... but it was your 1st run and could very well be because of your skill

I did once couple years ago when my car was around 30K miles at near sea altitude, around 60 deg & 30%-40% humidity (if I remember correctly). Lost the slip... Bone stock w/ street tires (S03) & ESP off.... I hit low 13's (I think around 13.1-13.3) w/ around the same trap as yours (give or take 3 mph). I did power brake at around 1500-2000 rpm (just right before the tires break loose) and then smoothly (not at once) flooring it.

It depends on what you want

- if you want to be able to tell people the car runs a low et then go buy some slicks, heat them up, and run them. Should take about 1/2 second or more off of the best time you can run on street tires.

- if you want more performance all the time, on your street tires, then open up the tuner catalogs (brabus/renntech/kleemann/etc) and have at it. I think at this point the conventional wisdom is that the carbon airbox is not worth the money spent, pulleys do little if anything to et's, and chip tuners are getting some gains here and there on some cars. The consistently fast 210 E55's all have superchargers.

I for one have been continuously thinking about doing a small dry shot on the car but am not willing to be the one who blazes the trail. Without knowing more about how the 210 naturally aspirated engine measures its incoming air, I wouldn't want to do a dry kit and not get some sort of additional fuel enrichment from the ECU. The intake manifold design doesn't look good for a wet kit since the runners are long and you'd risk fuel puddling.

Also, in its stock form the 210 E55 is a seriously fast car and you will have a hard time finding many other cars that would give you a run for your money. I'm focusing on doing small things to mine (suspension/wheels) and putting money off to the side to buy a drag car - I'm not going to try forcing my car into being something it's not. The 211 guys are lucky because they have factory power adders that can be tweaked.

295 WHP stock, about 13.3 sec. according to a G-Tech that was surprising accurate in another car when tested at the track. With "minor mods" I am now at 426+ WHP, but don't have any ET slips yet. I'm guessing 11.9X to 12.2X, but who knows, traction is a problem on street tires.

JamE55

Must be that CF engine cover that added all those ponies huh? lol :p

AMGPARTS18

Does the Renntech air box make any horsepower or is it all for show?

X55

Earlier this year a forum member was selling a Renntech carbon box for the E55. It looked like a modified stock box with a little more volume. I'd bet that the majority of the gain reported by Renntech with their box is due to switching to freer flowing filters within the box and eliminating the metal screen, rather than the box design itself. I wasn't impressed considering how much Renntech charges for it.

........X55- very well said!!

Low 13 is entirely possible stock. Pocholin probably had the quickest stock W210 E55 at right around 13.2. I was able to get a couple of low 13.3 at 107-8 but that was after having my ECU reflashed by Powerchip. Good advice on the launch technique. Any more RPM and you'll go up in smoke! I tried BFG drag radials but they did not improve 60' times as much as I thought they would only netting me .05 in the launch.

Hi guys, I posted this on the CLK55 forum on Oct 14th 2005 .....



I have a '98 model W210 E55 with about 80K miles on the clock and managed a personal best of 13.224sec at 107.32mph. My car's basically stock except for K&N air filters and i ran with a half tank of 98RON fuel with octane booster added. Back seats, spare tire plus jack were also removed. Car runs on street tires (Falken Azenis ST115; which i don't believe is sold in the US).
This run was made on Weds Oct 12th at WSID, Sydney, Australia. (Elevation is 70m or 230 feet above sea level) Conditions was as follows ....


Time 5.58pm
Air Temp: 17 degrees Celcius (62.6 degrees Fahrenheit)
Relative humidity : 82
Absolute Barometer : 30.00
Track temp : 29 degrees Celcius (84.2 degrees Fahrenheit)


Here is the break up of my run :

R/T : 0.181
60: 2.035
330: 5.632
660: 8.573
mph: 82.22
1000: 11.105
ET: 13.224
MPH: 107.32


I am quite happy with the results as my previous best at this dragstrip 2-3 weeks prior was a 13.339 sec at 104.11 mph (60 foot time was 2.053 for that run and conditions were : Air temp 15 degrees C, Rel humidity 56%, track temp 26 degrees C ).

...fyi for you other fellow American'ers 'n case you're thinking that means 98 Octane in the "US Octane" sense of the word that we're used to... RON98 converted to the US standard, which uses the (RON+MON)/2 rating system, where MON = 89 for our fuels, yields (98+89)/2 = 93.5 . So figure, that's like using the best Sunoco you can get.

t-boy

With V8 AMG getting low 13's along with some others it makes me think I need to try again and shoot for a 13.5 or better. I did't have my spare out which may help a little. Would higher than 93 octane gas help? Also nobody has yet to explain to me the K&N filters? What are they, do they help, are they easy to put in?

X55

maybe

probably not, because octane doesn't make horsepower

they are replacement air filters

www.knfilters.com <--will explain everything
