OK, I just got back from my test and tune session at Sacramento Raceway. There was not alot of people there so I got a good amount of runs in. Here is my problem. My best time was a 13.6 at 98mph. This is a 09 R/T, with a Techco supercharger,Tuned by Techco when supercharger was installed, corsa exhaust and Hurst shifter. It is only running 5.5 psi boost, but it is dyno'd at 448rwhp and 446 ft lbs of torque. I am running 305/45/R18 M/T Drag Radials and they are nice an sticky. At first I couldn't get the launch right( never raced with drag radials till now, also first time with a stick). I can't seem to figure out what I'm doing wrong? I launched it at about 4,000rpm so it would not bog off the line, got a little wheel hop but nothing too bad. Any advice on what I might doing wrong? I figure I should be in the 12's with this setup, and my MPH says different. Thanks for any tips or advice on what to do.
