I ran my SHO at the track yesterday (DA of 1916, track air temp was 70F but the track was heating up) with my latest tune. The manifold temp was 160F or higher. I still have the stock airbox, stock exhaust, stock everything even 30k mile worn out RS-As. I only added the 3-bar MAP, colder plugs, and a colder t-stat (but feel they aren't needed). Ran 12.4 @ 110 all day long with 1.8 60', all day long with variations in hundredths/tenths of a second/MPH.
I ran up against a brand new Dodge Charger Scat/392. The SHO launches like a bullet off the line and through the 1/8 mile, but past that, the Charger hauls serious ass and blew past me right at the 1/4 mile line. We ended up finishing within 0.041 seconds but he claimed that his best ET of the day was 12.6
I looked up magazine tests, and they rated the Charger 392/Scat as 12.4 @ 115 mph with 0-60 in 4.1 and a top speed of 175 mph which is fairly bad ass for a car that's priced slightly more than the SHO but you get a sweet sounding OHV V8 (not as nice sounding as the 13-14 Coyote GT that was smoked by the SHO).
I think with the Charger, throwing on wider stickier tires, and some exhaust and intake mods would make a great daily driver until you run into snow. I hate swapping to snow tires in SE MI because we can count the number of snow days on one hand that require snow tires. The rest of the 6 months of winter is mainly cold, slush, salt, or icy patches.
