I've had a few runins with srt8s at higher speeds before, but none from a dig or lower speed rolls. Yesterday I got the chance to do multiple runs. From a dig the mcoupe would win pretty easy. In defense of the SRT8 I am running r-comp tires and they hook up pretty good when warm. From a low speed roll the SRT8 would do better and jump on me. The Mcoupe has crappy gearing and it is easy to get caught outside the ideal powerband at certain speeds (got a new rear end sitting in the my garage which should address this issue :devillook)
Higher speed rolls are pretty close, with the win going to the m eventually as it slowly pulls away. Overall the cars are a pretty close match. Props to the srt8 drivers for almost always being up for a race.

Plus the power:weight difference between the two is huge. Nice races.

I would have imagined the SRT-8 pulling.

Guess M Coupes are pretty quick.

mods on your car?

Not sure I understand the M pulling from high speed rolls but not low. Doesn't he have 100hp or so on you?

100ish HP 1000ish pounds and an automatic.

100ish HP 1000ish pounds and an automatic.

But don't the 1000ish pounds and automatic mean significantly less at high speeds than low?

FWIW,
My brother has an 01 M Coupe and my uncle has an SRT8 and every single time they race, the M Coupe wins no matter how they go, dig, roll, freeway etc.

The SRT8 weighs A LOT(I believe they're ~4300, which is another 300lbs more than an E39 M5), even though it does have a substantial power advantage over the M Coupe, not to mention the torque.

I ran a few when we used to have an E39 M5 in the family and I would walk away from them without much effort; I would expect the S54 wouldn't have a problem with them.

weight dif means less at high speeds but the automatic plays a more detrimental roll at high speeds..automatics are FTL @ highspeeds

Remember, we're talking about the S54 M Coupe They can run low, low 13's and pull off ~109mph traps if driven properly. They are vicious and very capable cars in the right hands.

how much HP is that M coupe runnin?

I'm surprised with an M Coupe doing that as well unless modded. SRT-8s trap in the 108-110mph range unless heat soaked. They also top out at over 170mph and the HP peak is at 6000rpm so it's got good top end. Props to the coupe!

However, a 70mph race from a roll is a problem - it's the bottom of 3rd and somewhat sluggish. I raced an M5 at 60mph and 70mph. At 60mph I pulled 1-1.5 cars, at 70mph he pulled 1-1.5 cars. It was all gearing.

My fully loaded Charger with a full tank of gas weighed in at 4198lbs +/- 20lbs of variance on the scale.

There is a video and fully documented races, multiple runs, of an 300C SRT-8 vs. a stock E39 M5. It's on both forums. It's basically dead even - about the closest match up you can find. To "walk away from them with out much effort" is either BS or it wasn't an SRT-8, PERIOD.

nice job slaying a 6.1L Hemi :buttrock

Here is a vid of an M5 racing an Srt8 300C I believe. it was close especially when the M5 uses the stck intake.

Now is an M coupe faster than an M5 ?:dunno

calculate the power to weight ratio. I believe that the e46 m3 and e39 m5 (4023 lbs and 400hp) have about the same power to weight ratio and around 10 lbs per hp. The M coupe is lighter than the e46 m3 (3415 - 3131 = 284 lbs) if I'm not mistaken. Not that this proves anything for sure but it should dispell doubt.

Wow...it looks like the M5 pulls alitte w/o the intake. I know the S54 M coupes are about even with a stock E39M5.Both cars have gotten into the high 12's with good rubber by board members..bone stock. Now this one has R comps..that should make launching cake and 12's very achievable

Watching that video it looks like the M5 driver isn't so hot. Not sure where he's shifting, but I am sure he is slow at shifting. Hell, the passenger in the SRT8 laughs at him on the first race because he lost so much ground on the shift.

Looks like a driver's race with the edge for the M5 and the driver skill of the SRT-8 driver isn't a factor as all they have to do is push the go pedal.

qft autos are parasitic at any speed.

Here is the thread from the 300C forums. M5 forums is similar too. They did quite a few runs.

The M5 driver needs some lessons.

FWIW,
I ran a 13.01@110 at the 1/4 mile. I think S54 M Coupes can get that as well.

Armo! You need to go to MIR with me on the 19th. It is the last day the track is open and it is a test and tune. If the day is nice then i gonna be up there( if i can get this diff bolt issue resolved). you gotta bring the beast up there.

I just may. I just ran the car two weeks in Hagerstown, at a track called Dixon. It's an awesome track.

I hit my best mph of 110.49 there. I had three runs total, the best being the 13.01 and my worst being a 13.2.


I'll let you know about the 19th, I may out of town that weekend.

Why would you say that?

Stock SRT-8's have seen 12.8's.
The 2 cars are very evenly matched, as the video shows.
But you see a BMW driver who needs lessons.? :confused

Did you watch the video? The E39 M5 loses significant ground between shifts, especially in the first race that's noticeable. Or did you not watch the video? :confused

And? Who said they haven't seen 12.8's?

I'm sure I can run 12.8's with more practice, but I have nothing to prove. I'm not a fan of drag racing, not by a long shot (just wanted to get a feel for where I was with the car).

Some even a lil faster!

Watch the first race of the video; it's obvious he may need some lessons.

Quite a few have hit high 12s and one freak 12.56 @ 111mph. 35-40 degrees, 1.87 60ft. Low 13s is the norm. It's a great match up - provided you don't start at 70mph!
