I ran a 12.3's at 111mph (if memory serves) with my 181, but my MPH was inhibited by running lean. Once I correct the issue I ran a 12.3 at 116. Obviously both days I was running street tires.
Once you up the boost you'll likely smoke the tires (2.0-2.1 60') and run another 12.3, but the MPH will be much higher (114-117) due to the higher power and spinning. If at that point you install DR's/Slicks, your ET will be lowered by 2-3 tenths, which will in turn lower your ET by the same and result in high 11's. This is based on my experience with racing and the Crossfire in particular.
Do you still have the SRT seats?
Makes total sense, thanks! I was pleasantly surprised with my runs today. As Steve mentioned, I was going to be quite happy with a 12.5 but figured with the weather and other misc. gremlins, a 12.7 would likely be my time.
Boy, did I undersell the car!
And yes, I have the SRT seats.
