Ok, just got the car a few days ago and was dying to see how fast it was. Couldn't help it (I know about break-in, but a few 0-60's can't hurt).

Ran only 3, but ranged from about 5.8 to 6.1

I started the watch when I hit the gas and stopped the watch when the spedo hit 60mph...I felt the traction was very good.

Anything to be concerned about? I guess I will try again in 1,500 miles when the engine is broken in. Hopefully then the times will be more impressive.

The fact that you used a stop watch and think its accurate enough to warrant concern. :p You'd be lucky to get within a second of the real time using that method

Most of the time cars will 'gain' more power after a few thousand miles.

What are you driving.. if it's a C55, then you've got problems.. if it's a C32.. sounds pretty good.

I get between 6.5 and 6.8 on my CDI, but the book figure is closer to 6.6.... I think those numbers are with test equipment, etc..

Also wait for the engine to brake in... it will get a few more horses.

vraa

5.8 from a C32?
I thought C32's were about a whole second faster...?

smjjpres

Yes, it is a C55. Hope i don't have a problem, though, those figures certainly elude to one!

CE750

****, you should be in the low 4's... I wonder if there is some kind of "Break-in" governor mode to protect the engine.. My bro-in-laws old CL55 (which weighs 1000 more lbs) did it in 5.0 flat on my stop watch.

Go test drive another c55 and see if it feels the same. The engine should improve after a few thousand miles

I would have to think its your thumb and not the car.

get a G-meter or hit a stip>>>>>

I just G-Techd my car a few days ago. My first 2 runs were 6.1sec 0-to-60.
Then I brake torqued and pulled 5.4. This is with myself and a passenger. I'm positive it will do better!

vraa

You shouldn't be that high.
I've seen M3's (or heard reports) of them in the high 4's.
Work harder...

how many stock m3 can pull a high 4?

smjjpres

What I do not understand is how C&D can run the car at 4.7s totally stock.

I am by no means a professional driver, but, I have been driving sports cars for more than 10 years and have a decent feel for things.

To shave off a FULL second? Seems unlikely. Maybe a few .10s here and there, but, how off could me and the stop watch really be?

Maybe those Greenfilters are prohibitive as that is my ONLY mod.

No idea man, this is remembering stuff I had in an argument freshman year. C32 vs M3.

That's what BMWUSA says I think

CE750

that is your one major variable, and the dealer will insist you remove them before they start looking for problems with your engine.

Another option is to pay and have it dynoed, I did it for $120 and it was worth to see the 411 ft/lb torque with my own eyes (Assuming a 35% correction that is).

vraa

35% correction on what?! Back to SAE corrected numbers?
The AMG's should have something around a 25% driveline loss (from what I'm assuming as a automatic).

I normally use 20% as it's a pretty nice automatic

E55AMG99

Interesting.....I must be 4.5-4.6 in the E55 because I can pull a stock M3 pretty good. My early runs with the G-Tech said 4.6 but I had rhe weight wrong. After using the right weight, all I could get was 4.8.

I need to try it again after the new tires get worn in a little more.

vraa

Easily.
Torque wins races.
Horsepower sells cars.

E55 has torque.

Don't you love my logic?

E55AMG99

Yeah, Ricky. I do love your logic!

CE750

yup some 100 more than my torque monster if I recall..

Black C32

If its a C32 its pretty good?? Not so sure how you think 0-60 in 5.8+ is good for a C32. Its bad for a C32. You drive a CDI and not a C32. Do you own a C32? I suggest you edit your post and take back the ignorant false statement ASAP.

vraa

Okay I did a little bit more research. Lots of folks are hitting the mid to high 4's with TC and what not in the M3.

C32 should be matching pretty much that, they are direct (seriously direct) competitors.

But that's a moot point, the man has a C55, which should be as fast as, or faster than a C32.

So I've concluded that the parent poster needs to wait another few thousand miles and attempt again, however with a much more accurate way of measuring his performance. A stop watch has simply too many variables.

E55AMG99

My 99 had 349HP/391LB stock. According to Powerchip, it should now have 368HP/410LB.

vraa

Now that you've chipped your car, it's not more so of the gain of the line on your power curve, but what's underneth the power curve.

CE750

Go shove it pal, or at least your elitist attitude.. I've driven 90% of the benzes sold today.. my family together probably has more AMG's than most dealers in their inventory. I chose to drive a CDI cause I believe in Diesel, not cause it's all I can afford.

The stock C32 is between 5.1 and 5.3 in all the published data.. so a driver could easily time it a 5.8 on a stop watch by had.

Are you saying the C32 is quicker than the C55 or something?
