[QUOTE="dgdoc, post: 12239505, member: 122178"] Good feedback. Sounds like there is indeed a fine line between clutch slip and throttle application. With the street tires, they spin very easily, and that's not what anyone wants. Also, you are correct that there is some form of Clutch Protection: [B]Clutch Protection[/B] (Page 12 of GT500 Supplement) "[I]Your vehicle is equipped with an electronic powertrain feature to reduce clutch damage. When excessive clutch slip is detected at a high power level, the powertrain control module will limit torque to reduce damage to the clutch. Full power is restored as soon as the clutch is fully engaged. This feature is calibrated in a way that it does not interfere with normal driving and [COLOR="DeepSkyBlue"][COLOR="Blue"][/COLOR][B]does not impede maximum acceleration capability[/B][/COLOR][/I]" Anyway, still intrigued that MotorTrend managed to run 11.6 @125 with the stock tires. [URL]http://www.motortrend.com/roadtests/coupes/1205_2013_ford_shelby_gt500_first_test/viewall.html[/URL] Given enough seat time, believe good drivers will be able to beat that time. When the C6Z06 came out, the magazines ran 11.7@125, (which was the spec from Chevy). Over time (5 years), racers managed to knock 0.7 off of this time on street tires, and a full second on drag radials. Did you have a chance to try the technique of hitting the throttle harder/quicker, getting the engine into it's power curve, then letting the clutch lock-up, to see if this changed things? [/QUOTE]
