Coming to work this morning, real early in the morning, stop at the stop light to turn on to the freeway on ramp and a new C55 lines up next to me. The driver looks over and gives a quick nod and jerks his car forward an inch or so to indicate he wanted to run.

Light changed to green and I slammed on the gas. My wheels start smoking like crazy, but I finally hook up. By the time my traction is hooked again the C55 is about a full car length in front fo me. I hit red line, shift, I am caught up to it, another second I am in front, by the time I hit 75mph and merged on tot he freeway the C55 was behind by good 10-15 feet.

He rolled by and gave me a thmbs up once we were on the freeway. We couldn't go any faster at that point as the freeway was congested and traffic began building up.

Good race and good attitude fromt he driver of C55~! He obviously knew the capabilities of my car, but wanted to run anyway, kudos to him!

Specs on my car:
300C
JET performance chip
Dynomaxx Headers
Exhaust mods
AirRaid Cold Air Intake

Last dyoned without headers and chip at 318rwhp.

Interesting. I always thought that a stock C55 can outrun a stock 300C easily given the specs and magazine performance numbers.

The 300C SRT-8 is a whole different ballgame.

However, I see that you have modified your 300C with real-time results to show!!

slk320

I will tell you right now, that I would rather drive the C55 The 300C or SRT8 are only good in the straight line. If I had to take a corner then any horsepower advantage I had would have disappeared completely.

I did race an W210 E55 before and had similar results... I know I can't beat a W211 E55

Nice run! I test drove the hemi-powered 300 with my parents (who were thinking about buying one). Nice car, but not really well-priced IMO once you option it up (easy to break $40k), and considering that discounts are pretty much out of the question on the hemi model. Mom got a better deal on the new Avalon.

E55 RUSS

Oh...I thought NEW C55 was much FASTER

Vomit

Oh...And we assumed that if you can TYPE English you can READ it too (the Chrysler is modded)

slk320

Well, I dodn't know... this is the first time I ran with C55... I think its a real nice car!

From MBUSA:

C55
362 hp and 376 lb-ft 0-60 = 4.9

I think that right now, I have a bit more horsepower then that... Its hard to calculate with drivetrain loss ration, but our best guess is its closer to 380-390hp.... My G-tech read 5.2 to 60, so it could have been more of a driver's race anyway.

Maybe the guy wasn't punching it

Fast55

Maybe if the C had a couple plug wires pulled off. Those mods won't amount to enough HP to touch a C55.

slk320

I have more rwhp then C55...so I am not sure where the "touching" comments come from. I will not touch a W211E55...but a W210 E55 I beat..routinely.

Vomit

What does the 300 weigh?

Thericker

I found some info at Autotrader.com
Mercedes C55 curb weight 3500lb
Stock 300c 340hp 390to
as far as weights all I could find was a listing for the 300m w/V-6 engine
curb weight--3766lbs
Now you know that big Hemi must weigh a lot more so he's probably in the 4200lb area
they also had a review by Consumer guide and they had perf. quotes for the 300c 0-60 6.3 seconds!!
With that info I agree with the other doubters---NO WAY W/OR WITH OUT YOUR MODS WOULD YOU EVEN TOUCH THE MERCEDES C55 AMG...
All you'd be seeing was tiny little "C55 AMG" badging fading away very quickly in front of you...Dream on dude The only way you'd be able to even hang (not even beat the C55) would be to get a Supercharger on the Hemi....Or buy the SRT-8 that comes w/6.1 liter

zoink

Hmmm.... w/ only 5.2 to 60, I don't think you could say you could beat W210 E55 "routinely".... unless you met w/ some ppl who just tried to play catch up. W210 E55 is ranging 5.0 - 5.4 to 60.

C55 performance is a bit faster than W210 E55... claimed to be 4.8 - 5.2.

Also, I would be pleasantly surprised if your mods could drop your 0-60 by 1sec. I raced couple 300C's before and they could not even touch me.... I guess they were stock.

Well.... on the street, anything could happen.... driver's skills, driver's guts, tires, lanes, etc. etc. etc. so I would not discount your claim unless you said you routinely beat C55.

slk320

Like I said before, I would rather drive a C55.

I don't know whether the guy was going all out or whether he was saving his engine during break-in (still had dealer plates). Could be either, I am merely constituing the events of that morning.

I forget sometimes that the only "kills" allowed on this forum is when Mercedes wins... The E55 W210 that I have beaten was a friend of mine; and when I say routinely I mean the same car time and time again.

zoink

No, your assumption is wrong.... the only "kills" allowed in this forum are the "believable" ones... which is when all numbers and odds add up or are likely to add up (if it's already an obvious win, it's not a kill anymore, right? ).

Unfortunately, your numbers and odds don't add up... that's why you got a lot of skeptics:
1. With your mods, it's hard to believe your 300 is 1 tick less to 60
2. Even w/ your mods and your claim that your car just needs 5.2 to 60, C55 is still faster (test results: 4.9-5.2)
3. Your claim at the bottom of your first post of this thread:

sounds like your strong belief that your car is (a lot?) faster than his, which all of us in this forum do not believe (especially when you said your 0-60 was "only" 5.2).

Well, you're still lucky our famous member, IMPROVIZ, has not seen this thread. He always trusts the numbers and real results, and would challenge anyone who said otherwise.

Once again, I don't discount your victory.... if that's what happened, then yes, you won and killed C55.... but (there's a but) ...

it was very likely one of the followings happened during the race:
1. C55's driver did not really push his car (like you said, may be because it was new)
2. C55's driver did not know how to drive (why did he even buy C55? LOL)
3. C55's driver did not have gut
4. C55 had an engine failure (lemon may be )
5. C55's driver just wanted to play catch-up (I did that 95% of street racing - less likelihood of getting a ticket ) as he just wanted to confirm that C55 is faster

Otherwise, if all of the above were not true, it was either a fluke (which should get a rematch) or I think C55 would kill or slowly walk away.

To put it into more extreme.... just like if I claimed my E55 beat modded Z06... hard to believe as odds and numbers don't say so but it came true one time. Not sure what happened... driver's skills?

Peace...

Vomit

I find the kill feasible. He dynod at 318 before additional mods. Probably 340 RWHP would be a good guess now. The C55 dynos around 300. It would be a close race (which it apparently was).

AMG or NOTHING

Dyno? What dyno? Butt dyno?

Thericker

Exactly I didn't see any Dyno graphs, just some #'s he posted up could be anything And Vomit what about the weight difference of near 500lbs??Also those mods Ecu, headers, = hardly any gains to the rear wheels on a non-aspirated motor..add in the intake and exhaust he might gain 40 total hp at the crank, So what are you talking about

Fast55

Anything is possible, but it doesn't make sense. A 300C is a 14 sec. car at best, a C55 will break into the 13's easily. Even if the dyno numbers are correct, you need a lot more than a 40 HP advantage to overcome 400+ lbs. of weight.

EuroCoupe

The Jet chip for the Hemi 300C gains 22hp at the wheels with tuned exhaust/headers and intake (according to their website). If he's telling the truth about the 318 at the wheels before the chip and header mods, 340whp is believable, no problem. Check out this Car & Driver test link. Car weighs 4100 lbs and change. They got a 13.9 1/4 mile in stock trim. Give this guy a break, a C55 will not walk away with his mods... If he has 340 whp, he has a slightly better power to wieght ratio if a C55 gets 300 whp.

Thericker

Listen...I'm all for mods but you can never believe Manufacturers hp claims there BS over exaggerating...Proofs right there "22hp gain at the wheels" Please!!....On a non-aspirated motor that's a laughable hp expectation as well as headers, anyone that knows anything about mods will tell you gains from headers on a non-supercharged engine are nil to none >5hp.... Yes a C55 will blow past him..Please someone that owns a C55 step up and prove this guy wrong

Vomit

Also, why would he lie? He is not a troll (check his vehicle ownership). Why can't you all fathom the POSSIBILITY that a car which runs a high 13 or low 14 in the 1/4, when moderately modded, could run with, or even slightly outrun, a car which runs a low-to-mid 13 second 1/4?

My guess is that his modded 300 Hemi is probably running almost identical 1/4 times as a stock C55. If my C32 were stock, I certainly would not "bet the farm" on a race with a 300 Hemi with his mods. What's the big deal people?

Thericker

Why can't you FATHOM The possibility his mods don't=====SQUAT!! ON A NON SUPERCHARGED MOTOR THOSE MODS COULDN'T ====MORE THAN 35-40 HP AT THE CRANK So about 15-20hp extra at the wheels

Vomit

Well, then, maybe he has Costco nitrogen in his tires

Thericker

Now your talkin' that must be his perf edge

zoink

Dude... chill out On the street, anything can happen.... slow car beats or "beats" fast car... I should put a quote there as to distinguish people who claim victory over someone who does not even know he is racing...

Kind of the experience I had when an STS or CTS passed me when I was cruising along local road.... I knew he was next to me for a while and did not know he asked for a race... he slowed down and passed me very fast (he must've floored the car) and shortly after, the blinkers turned on hope he was not claiming victory

Or.... playing catch-up is also common.... I typically know whether my car is faster or slower before I actually pass...
