I'm going to have to drive this
... it's REALLY growing on me and I LOVE the blue/white stripe combo... I remember St Antoine's (the only MT editor I consistenly agree with) 3K odyssey drive in the Challenger SRT where he harkened back to the old days, more than he felt with the Shelby... gonna to see if I can line up a drive back-to-back with the Shelby... alas, our first real snow begins falling this afternoon... looks like a fun spring ![Cool](https://www.clublexus.com/forums/images/smilies/cool.gif)

It's not likely the 2010 Dodge Challenger SRT8's 6.1-liter V8 strikes you as meek. However, in a move that surely rankled Dodge's marketing gang, the Camaro SS debuted with 426 horsepower to the SRT8's 425. That's too close to be a coincidence.
There's just one thing to do. See, there's an old adage among hotrodders, and that's: Adequate substitutes for swept internal capacity are curiously nonexistent.
No, that doesn't sound quite right. It's... There's no replacement for displacement.
Dodge is reintroducing the storied 392 V8 engine for the 2011 Challenger SRT8. That's 6.4-liters for you metric weenies -- 0.3-liter more than the outgoing SRT8 -- and it all adds up to one mean Mopar. We'll have a full test including video of the Challenger SRT8 soon but in the meantime, check out how the bored and stroked Hemi fares on the dyno after the jump.
Okay, the 392 is actually 0.8 cubic inches shy of 392 cubic inches, but such white lies aren't unheard of -- examples like the Ford 5.0 (a 4.9-liter); the AMG Mercedes-Benz 6.3 (6.2-liters) come to mind. Heck, even the "Hemi" label itself is bogus for the moden version as it has pentroof combustion chambers and not hemispherical ones.
That's all window dressing. What really matters is this: the 392 is rated by Dodge at 470 horsepower and 470 lb-ft of torque, and the 2011 model not only makes bigger numbers than the outgoing SRT8, they arrive sooner too. Peak torque arrives at 4200 rpm, some 600 rpm lower in rev range than the 2010 model, and peak power hits at 6000 rpm (the 6.1's peak power is at 6200 rpm).
On the Dynojet chassis dyno, we measured the 392's potency thusly:
Torque hits hard and early, with 365 lb-ft on tap at 2500 rpm, and rising to a peak of 443 lb-ft at 4400 rpm. From there it rolls off gradually until the 6200 rpm fuel cut. Peak power of 452 horsepower arrives at 6200 rpm, so it's safe to say that this bruiser is making at least what Dodge claims.
Whereas the 6.1-liter was relatively thin at lower revs, the 392 delivers big torque off idle, and brings a friendly torque curve with no flat spots or hiccups. On the dyno it was dead-repeatable, and the autobox's manual mode let me hold the gear of my choosing as far down in the rev range as I desired without deciding it was smarter than me and delivering a bunch of unwanted downshifts upon goosing it. Nice.
About the SRT8's cross-town rival, the Camaro. It happens that we dynoed our long-term 2010 Chevrolet Camaro SS on this very dyno last year. Here's how the new Hemi compares:
That's pretty much an ***-kicking, particularly in the midrange where the 392 wallops the Camaro's LS3 V8 by some 100 lb-ft. The Chevy's ability to rev slightly higher isn't nearly enough to make up for the huge disparity in weapons-grade grunt. However, the SRT8 costs substantially more than the SS, and there's a supercharged Camaro Z28 on the horizon.
This brings to mind another old adage: Velocity is proportional to the weight of your man-purse; can you kick down a tenspot for beer and nachos? I'm pretty sure that's how it goes.

My brother has been looking for a new pony car and I've been trying to steer him in this direction. He's not into Mustangs; and we both think the Camaro just looks a little... off. Out of the three at least, I think the Challenger is just a little bit better looking than the Mustang (flame suit on). If I was shopping for a new V8; I'd gladly take either though.
I'll have to get the Buick out in the spring and get it dynoed to see how the engine compares, hopefully I come close to that torque number.

Every one here knows my affinity for the Shelby Cobra but ever since the re-design, there's just something I can't quite get that's off about it
... when I look at a Roush, I don't see it, the Roush just flat ROCKS... with the new Challenger in blue, it's instantly more exciting than both the Shelby, the Camaro is FAR in the rear view... just can't quite figure it out... ![Uhh...](https://www.clublexus.com/forums/images/smilies/1387914497.gif)
![Uhh...](https://www.clublexus.com/forums/images/smilies/1387914497.gif)
but I think it's the wheels and rear diffuser....
