i have about the same stuff you got accept i run drag radials now but when i was on street tires i pulled up and did a little burnout NOT in the waterpit! then pull up and get it stage and hold it at about 3000 and have the clutch ready to engage and let the clutch slip a little on launch, DONT drop it tho let it start to fall on its face then give it hell good luck!

if its stock turbo dont launch any higher than 2000rpm as more than 90% of peak torque is available from 2000-4600rpm.....

roll into the water box and spin the tires just once, move out of the water box and spin em till they squeal. launch about 1800-2200rpm feathering the clutch and make sure in 1st you don't smash the gas pedal to the floor u gotta "roll" it down, a nice steady acceleration. shifting into 2nd comes at about 5800 rpm, DO NOT WOT SHIFT 2ND, however WOT into 3rd+4th is fine. and the tire pressure does better around 22psi in front and 40 in the rear

i know 2000k drop on street tires will result in nothing but wheel spin, my advice is no higher then 1000-1100rpms feather clutch and ease into gas, no powershift for second and make sure to deflate the tires a bit....happy now?
