I'll be sure to send you a pm after my mods get finished. Pretty sure a 400rwhp car that weighs 2400 lbs will beat a viper. Right now I'm only good till about the 1000 ft mark until I get dusted. Dr. Dirt I have raced 3 different stock SC Cobras at BMP at track events and a couple at Sunshine. Pretty confident they didn't all screw up. Like I said weight does make a difference. If it didn't guys wouldn't be gutting their cars. Look 12.845 with only 251RWHP in the 1/4. I'd say weight and driving make a hugh difference.
