Anyway, I WAG'd a 1600 stall converter with a 1.8 stall torque ratio. I don't have a power curve for the hemi, so I had to use just the peak numbers. What I came up with is 0-60 in 5.9 and 14.28 @ 101 mph. C&D had 0-60 in 5.6 and 14.2 @ 101 mph, so I figure I'm pretty close.

DD had the charger's 60 ft time at 2.6, which is horrible. So, I swapped in a 3000 stall converter with a 2.0 STR. WITH NO OTHER CHANGES, the 60 ft time dropped to 2.0, 0-60 dropped to 5.0 and ET dropped to 13.52 @ 102. Going to my current conveter, a 3500 stall converter with a 2.5 STR, dropped the 0-60 to 4.8 and the quarter in 13.33 @ 102. No engine changes, no intake mods, no exhaust mods. Just a converter.

So now that I have the software reasonably close to reality, I put the SRT8 in. With the same stock converter, the numbers were 0-60 in 5.1, 60 ft in 2.4, and the quarter in 13.3 @ 108 mph. We've already had word that a stock 300c SRT8 has done a 12.9 at Cecil, so again, the software seems fairly close to reality. The 60 ft again is really, really bad - ideally it should be somewhere around 1.7 or 1.8. So on goes the 3000 stall converter: 0-60 in 4.5 and the quarter in 12.9 @ 108.

The 3500 stall converter with 2.5 STR gives 0-60 in 4.2, 60 ft in 1.8, and the quarter in 12.5 @ 108 mph. Incidently, with this converter the car crosses the finish line in 3rd gear at 6495 rpm, so the stock gears are exactly perfect. Changing the gears to a 4.25 rear to hit redline in 4th across the finish line netted me less than a tenth, so rear gear swaps are probably not worth much in this car (although they may be worth more with a milder converter).

Parameters were:

car weight: 4300 (with driver)

RT rear gear: 2.83

SRT8 rear gear: 3.06

RT redline: 5750

SRT8 redline: 6500

Typical track conditions

coverter was set at 96% efficiency.

Disclaimer: This was just a thought exercise, but I've been using this program now for several years, so I feel confident that the real numbers, when they come out, will be within a couple-three tenths of these predictions. I'd be able to get even closer if I knew for sure what the real torque converter's specs were.
