Have not gotten the Challenger R/T to the track yet, my local track doesn't open up again until April. But a little playing around has gotten me a 5.29 zero to 60 time on the in-dash timer on the streets. And it will be on the factory all seasons when I do get to the track. Eventually, I'll put a stickier tire on it but it will still be a street radial.

In my 06 Mustang GT with 5 speed manual trans, I got to a best of 13.67 at 103 while it was still bone stock, tires and all. With CAI, tune and underdrive pullies I was able to knock it down to 13.26 at 109, again still on the factory stock tires (and that was with a pittiful 2.06 second 60 foot time!).

So, with the Challenger, I want to do about the same thing. See what I can do bone stock, then make a few mods (CAI and tune) and see how much better it can get. I'm hoping it surprizes me on the track.
