Actually Botlfed did 11.4 at Las Vegas NV. Not sure what the alt is but I doubt sea level.
He does have stock long block, turbo, intercooler, tranny, converter with 130,000 miles and has ran a 75 shot around several hundred times. He has removed rear seat, a/c, stock seats, inner fenders, wipers & wiper motor, window & lock motors, no exhaust but 4 in. pipe of the turbo, has fiberglass hood, and bumpers.
Since has removed door reinforcement bar, fiberglass trunk lid, cruise control, radio, speakers, console, and anything not needed so I think it will run 10's, oh yea added a second stage of nitrous.
If you lighten it, tune your chip for nitrous, run to stages of nitrous 50 shot of the line and 100 hp after you reach 30 mph (because of traction) I think 10's are feasible even above sea level.
nitrous with two nozzles (50 & 100) attached to one bottle used should be around 250-300, good fuel pump(double pumper would be nice-400-500 used, send me a blank or used chip and I will burn you a chip that should be close for a stock Gn- free, good tune up (new platinum plugs, clean intercooler, clean throttle body, can of gm intake cleaner to clean carbon deposits, Tranny fluid and fliter, basic spring cleaning of gnttype board) 100-150. If lightened should be dam close to tens. If you have money left over by a progressive nitrous controller and use 1 stage of nitrous and bring it in over 1-1.5 seconds and that help with traction.
