ANY Cobra with a decent motor should get into the 11's. Certainly the motor you describe will, IF YOU GET THE POWER TO THE GROUND. I quarter pretty regularly, and have found the MT DOT race slick with lo pressure tends to work best for me. I use the standard 15" rim, a 15" wide slick with retaining screws and treat the tires with gum solvent. Launch mid range and hammer the throttle once you are hooked. I run a 9' with locker, usually 4.11's but sometimes 3.56 (my 'street' gear) and sometimes 4.56's. If you build the motor to deliver torque, it will be reliable and then you can play with the chassis to get the power to the ground. After awhile, you'll start looking for 10's!
