Assuming that the speed governor is eliminated and you have proper tires and flat open road, what speed can the stock 5.7 push a Magnum to? I found a thread where a stock (no mods listed) AWD hit 159MPH... I know that SRT-8s can hit a little over 170MPH before aerodynamics hold them back.

Would any mods aside from a turbo or a supercharger allow an R/T to hit the 170 mark? What would be the minimum mods required to reach that speed?

128 on a stock r/t. somewhere between 155 and 160 on a stock srt-8. both are electronically limited.

Gotta love the Superchips (and coming Morpheus). And rumor has it he topped out at 176 before shutting down.

I have been to 165 with my Magnum. The only mod is Superchips to raise the speed limiter and smaller diameter tires for a tiny bit of gearing advantage. The car felt as stable at 165 as it does at 100, like a rock on the road. I have also had mine on Mont Tremblant at a performance driving class and it feels great at 100 sliding through a turn ( Patrick, before you comment, I know sliding at 100 was not good, made adjustments to my line on the next lap!). I ran it wide open on track and wiped out a full tank of fuel in under 80 miles.
