My buddy's stock 01 Cobra with only K&N drop in filter and Borla mufflers ran a 13.0 at 107mph (that's bone stock 3.27 gears and IRS) in the hot ass humid Louisiana summer temps the other night at NO PROBLEM raceway. I have 4.30 gears in my 01- which would prolly give me a lil quicker time. Now what about an 01 not hanging with a Mach???? I know we can get our's in the high 12's with cooler temps.
