The SRT-6s 20HP/lb-ft deficit is probably either due to an artificial restriction in the exhaust, and possibly some sub-optimal fuel maps. If it's just the exhaust, I'm sure that only $1000-1500 is all it'll take to produce output similar to the SLK32.

The SRT-6 will probably only have, at most, a 100lb weight advantage to the Benz. Though if you cut those rear wheels down to 18s, you probably can shave off 20-30lbs between the tires and wheels. Running the tires 3psi under nominal pressure can also cut a tenth off if wheelspin is an issue.

Out of the box I'd guess the SRT-6 could do a 13.2 guaranteed. If you could get that 20HP/lb-ft back, a 12.8 @ 109.5 - 110.0 isn't out of question. Not bad at all for a Chrysler!

And let's keep in mind, this being a bonified AMG driveline, means that regular M-B modifications would likely be suitable for this car. If I end up grabbing one of these beasts, I'm going to give RENNTech a call. For about $3000-$3500, swapping out pulleys and massaging the ECU could easily bring output to 390-400 HP and lb-ft.

12.4 - 12.5 would be very realistic, meaning the SRT-6 would stand a good chance against a C6 Corvette in the 1/4 mile -- the best I've ever seen a stock Z06 pull was 12.2 @ 115, and the driver exhibited nothing short of perfection. Though I'm positive that on a road course, it'd obviously be the Vette hands down every time.

To sum it up... 60 in 5 flat, 1/4 barely still in the 13s. But for a few thousand dollars, the car could be a downright brute, and do burnouts on demand if the transmission and electronic safeguards allow. Again, not bad for a Chrysler.
