2009 challenger rt auto vs 2010 L99

[Mr CLuTcH]

Im not willing to buy that the 400hp/410tq SS is putting down the same rearwheel horsepower a 372hp/400tq RT Challenger. The Challenger should be putting down far less given the drivetrain loss. My SS puts down 355 at the rearwheels, stock, no CIA or exhuast and I've had no problems with Chargers or Challengers of any kind. Im happy with it's performance.

I just don't think the R/T is very close to the L99 in performance at all, given the circumstances. I mean, in every review of the big three, take your pick, the Challenger comes in last place in a drag race. And this is the SRT we're talking. So I highly doubt an R/T would be something to flinch at even for a average driver. Not putting down the car, I just don't feel the same about it's performance in comparison to an SS. Let me ask,....out of the SS and R/T who would win from a 60mph roll? Who would be the car left behind? Surely not an SS.

Ok buddy, have it your way.

All I know is my R/T, stock, put down 330 to the wheels. With just a CAI(and no tune) in 1800 foot DA I ran 13.266, which is the slip in my signature. I average 13.3/13.4 in 2000+ foot DA.

Lots of R/T's are running in mid-high 12's with just basic bolt ons. One member over on ChallengerTalk, HemiTx I belive his name is, runs 12.5's and faster with drag radials, longtubes, exhaust, tune and intake. Another with just a catback, tune and radials was running 12.7's and 8's.

In the real world the R/T's are just as fast in the 1/4 mile as the L99 SS's ON AVERAGE.

viper...we're paper racing here!

Stock L99 on stock RT the edge goes to the L99.
Against an SRT8 you'll have your work cut out for you.

[VADER SS L99]

The RT might and I stress might put down as much RWHP as the L99 but we have a big six speed trans, IRS, and 20" wheels with big diameter tires that eats it up. RWHP #'s on a automatic you can take with a grain of salt. Its what happens at the track thats the real proof. My 4th gen only put down 345RWHP but ran consistantly low 12's. On the same day on the same track with equal traction I would own a stock RT when I was stock. The advantage goes heavily in the SS's favor in every stat. It has more power, more torque, weighs less, and has better gearing both in the rear end and trans. Ther are even a couple of L99's that have run 12's bone stock with stock tires. If the RT had been a faster more powerfull car then I would have seriously considered it when I was in the market because the looks are killer.

Coming from a current owner of an SRT8 Charger, plan & simple, you will win. As mentioned many times above, the L99 is lighter & has more hp. After driver differences, those are the two biggest factors to consider.

To those who said the L99 can beat an SRT8 though, sorry, not happening. Not in most situations anyhow. The SRT's might weight more, but that's about the only advantage going in an L99's favor. Most SRT8's are actually rated lower than they really are. Not to mention the suspension & steering is much better in the SRT's than in the R/T's.

[VADER SS L99]

While I would agree that the auto SRT8 Challenger would probably beat me when I was stock I think it would have been a very good race with the Charger. What do you guys weigh? 4200lbs?

The Charger SRT8 and Challenger SRT8 have nearly identical specs when purchased w/ Auto trans. Both trap from 108-109mph when stock.

The Charger curb weight is ~4160lbs, the Challenger is ~4130lbs.
Both have identical motor, trans, gearing if auto.
Charger is setup lower and more firm (tighter handling).

Ditto on what Sleestack said.

[Mr CLuTcH]

Actually, the Challenger SRT8 weighs 4,140lbs,....not 4,130, checked dodges website.

So the Challenger weighs at least 240 pounds more than the L99(3,900 or 3,913) yet has 25 more horsepower and 10 more lbs feet of torque but somehow I just find it hard to believe that a mere "25" more horsepower is enough to overcome the car's 200+ pound disadvantage. To me, that doesn't make sense.

If so, Challenger/Charger defenders are expecting you to believe 25 horsepower alone is enough to overcome a 200+ pound weight disadvantage. Somehow, I just DONT see it happening,nor does that make sense to me.

Like I said, if that's all it takes to tip the race into your favor, a simple CAI (k&N 18.62rwhp) would be enough to allow an L99 to beat a SRT8. It will forever be a mystery to me how 25hp can overcome a 200 lbs disadvantage. Sure the L99 is heavy,....but 200+ pounds is ALOT more added to the car. Don't think so? Go place 200lbs worth of cinder-blocks in your trunk then tell me how performance looks.

I believe the SRT8 has better gearing than the Camaro.. correct me if I'm wrong

Actually, it is pretty well known that a 10HP increase will make-up for a 100lbs difference. Thus, it will take an extra 20HP for a 4000lbs car to run even with a 3800lbs car. If it doesn't make sense to you, you need to educate yourself. Like I stated before, the SRT8 traps higher than the stock L99. Until you can explain that, you don't have a leg to stand on.....

Ahh.... who cares about stock! or all the paper racing..?

you also have to remember that that dude aint taking into account aerodynamics (maybe the charger srt8 is better in that reguard than the flat front-ended camaro and challengers). And drivetrain losses between the two (dodge vs l99) doesnt seem to be the same. The L99 drivetrain for some reason seem to really love soaking up some HP! According to the "fastsest list" on this site, most are trapping in the 105ish MPH i believe.
