The problem isn't the power, it's the gearing. The SRT8's have taller (read lower number) gears than our cars have stock. With the extra weight these have over us, they need more mechanical advantage to the that barge moving. Lower gears means greater mechanical advantage, which is why so many of us have switched to 3.73 or 4.10 gears in our cars. I have no doubt that with lower gears and probably a torque converter, they could be high to mid 12sec cars right out of the box. The fact is that even with DOD, chrysler needed to put the taller gear in to avoid higher penalties for gas milage.

Ford went through the same thing with the GT500, that's why they come with a 3.31 gear - for gas milage listings to the government.

SRTs have a shorter geared tranny as well, as for times, high 12s, low 13s, either it was a 300C with only 345 HP or it was a baad driver

um. . . all SRT8's are 425 hp . . . and no 300C with only 345 is gonna go high 12's or low 13's. . . it needs that extra 80 hp if it wants to see those times. . . :-)

um nevermind, i see what your saying now

Im not sure how much 20 inch rims would slow you down. But looks like you have alll the basic bolt ons besides the drive shaft. So i mean Look at the mods i have and i raced a stock one and pulled decently on him. you have another 15 20 hp on me. Im sure 20 inch rims woudllnt slow you down to much.

Default RE: How fast are the SRT8s

Well I am a dodge and ford man, well I am confused, whatever. The point is I know for a fact that a 300C SRT8 completly stock less than 500 miles on the odometer with nothing but drag radials can run in the 12s, to be exact It was a 12.98 Yes they are good cars out of the box, however dollar for dollar on mods the mustang wins every day. Daimlyer chrysler really screwed the pooch when they made the hemi's with speed Density and a **** computer. You add an air intake and exhaust on a hemi and might get 15 rear wheel horsepower. You just cant get them to take to mods not even with a programmer. After that all the other mods including a cam along with ported heads and headers might net you 20 to 30 more RWHP. For a whoping 35 to 45 more RWHP so be glad that you are driving a mustang.

Your probably right. I knew it was higher than a manual GT's gear.I was going off of memory, and I have a very bad memory. But the rest is true, Ford did that to keep EPA listed fuel economy up. As for the GT500, drag radials and 4.10's, and I guarantee it's a 11 sec car. Look at the traps, all between 115 and 120, no matter which magazine is running it.

I had a 300C SRT-8 pass my stock auto GT convertible from 50mph, and I could only watch him walk away...
The Charger SRT-8s are a tick slower than a stock GT in the 1/4, but the SRT-8 300s have us by 1/2 second, acording to Car and Driver...

s-197s run high 13s, SRT8 is high 12s to low 13s, drivers race for a mach maybe, but also srt8s are only autos, and if you cant drive an auto, you dont deserve a car

Default RE: How fast are the SRT8s

I was at the track the other day when a 300C did 15.2s in all three runs, got even beat by a Nissan Altima (both are bone stock), wonder how much faster the SRT8 will be? it was 95 and the humidity was like 100%...
