SRT Engineers have confirmed no electronic limiters on SRT8 Challenger.I thought the SRT was computer limited to 168mph unless removed by a predator and that was because above 168mph you ran into integrity issues with body parts (i.e lowlife's one mile speed runs). I also thought the 2011 were computer limited to 180mph because of the re-worked front spoiler duct work allowed a higher top end.
If that's the case, wouldn't the manual tranny have another 290 rpm left in it; therefore, increasing the vehicle's speed over what was achieved at 5710rpm? What would be the manual's speed at 6000 or 6020 rpm?There is a gearing difference between auto and stick. For an SRT8 with F1 tires these are the approximate RPMs at 170 mph:
Manual trans 5710 rpm in 5th
Auto trans 6020 rpm in 4th lockup
As the maximum engine HP is reached at 6000 rpm, you would think the top speed of the auto trans model might be 1 or 2 mph higher than the stick car.
