As for myself - no. Apkano says I drive like a grandma, maybe he's right. I have only hit ~100 in it. I'm more of a 0-60 guy.

I had the speedometer up to
180 mph this morning, the tac was at 5,800 RPM and the car was solid as a rock, still pulling hard when I let off. With the car having 285's on the back, I would have been running
186 mph. Renntech tuned my ECU for 93 octane, I run 94 octane and they raise my redline to 6,200 RPM so I do think an SRT6 will hit the 200 mph mark, I got this following statement from a tire size calculator. --- When speedometer reads 60 mph (96.6 km/h) actual speed will be 62 mph (99.8 km/h): 3.3% faster.
