    Well.. Had a few runs at the dragstrip when stock and the best I could do was a 12.758 @ 112.91mph. Car had about 3,600 miles on it at the time.

    Had a Roush blower installed about 3 weeks ago and finally made it to the strip again this past Saturday. Still on the stock Michelin Pilots. I only had time for two runs that day due to all of the team events but this time I managed a 12.213 @ 123.09mph. First run I barely launched it because I didn't know what traction would be like (2.47 60' time, lol). Second run I launched at about half throttle and kept it there until I found the tires hooking up. I did not pre-load, launch was off idle.

    I know these times suck but this is my first rear wheel drive car with power and I am still learning how to launch properly.

    The slip on the left is my best stock run, the slip on the right is run #2 with a blower. Traction control was NOT on for the stock time but WAS on for run two with the blower. I could feel it kicking in for at least the 1/8th mile.

    The traction control killed you. 123 is good MPH. should easy be low 11's with that MPH. Your biggest problem is probably going to be traction with the stock tires.

    Seriously you need drag radials or any chance of consistancy will never be obtained.

    Understood :) Haven't had much practice with traction control off. Kinda scared to send it. Or break stuff! Heading back soon. Hopefully traction will be as good at the next T&T as it was during the team event.

    Turn both traction control & stability control off with a set of M/T ET Streets and you will enter a different world.

    With the blower, you will want to upgrade halfshafts when you go to a DR.

    But that's sure to happen anyway

    You have invested a good junk with the blower setup. Not sure why the first mod would not be a good set of drag radials. I bet you will even pick up more mph with the drag radials. Probably be around 126mph and drop an easy second.

    Definitely on the list :) Just seeing what my lack of driving skill can do with street tires before I go whole hog.

    No.. 300a. No extra modes.. If I turn TC off and floor it from a dead stop it doesn't move.. Just spins tires. Finessing the throttle isn't something I'm used to :)

    ya track prep also matters if its good. you might actually do slightly better pre loading the rear a tad and easing into the throttle. but of course grabbing some used 17x10 wheels with some tires at least some Street SS are going to make a big difference. toss in some torco and probably drop at least a second

    Get you some cheap 9.5 inch wheels and a set of MTs or NTo5Rs and let er rip. I’m fairly sure the DA at any Arizona track is very high. So you have that to deal with. I’d also run a can of boostane or similar octane booster. To insure your not pulling timing. Your good on the half shafts with the auto.

    Someone help me understand why some folks say the 10A is easier on halfshafts than the 6M. The A10 puts FAR more power to the axles in the lower gears than the 6M does due to the gearing differences. I realize the OP doesn't have drag mode but even in sport mode, the A10 shifts very firmly.....similarly to powershifting a manual. Those with drag mode or a tune have no torque management so the shifts are even more brutal.

    There have been a few people snap the driver's side half shaft with naturally aspirated cars when using sticky tires. Running a boosted A10 at a prepped strip with drag radials seems like a recipe for half shaft carnage.

    The difference is you can't launch the auto at 5 grand. So the launch is a lot softer. Most half shafts that I have seen break are on the starting line. The shock to the shaft can be much harder than on the auto.

    Screw all of the traction control shit. I turned that stuff off even on the street with my 2015 whippled mustang.
