What was your 60'? With that much power, you should be knocking on 11's door if you have the traction.

thats a good size turbo, whats the AR?. My brother and I are running 62mm, he ran a 12.1 @ 119 60ft@1.9 w/ street tires with about the same power 385rwhp/440rwtq.

If you want to get out of the hole HARD, then get some sticky tires (slicks or MT DRs) and a 2 step rev limiter. You can set the 2 step for about 4000 and build boost at the line. Then, when you let the clutch out, the tires will hook and you'll already have the boost to power out of the hole. That should give you an easy and consistent 1.6 60' time, even with an otherwise stock suspension.

Another, cheaper option is a small shot of nitrous. I picked up a used kit for under 150$ and spray a 35 shot on my 2.3. I spray it from the line which not only gives a nice boot of torque, but spools the turbo much faster. With the 35 shot, I have no appreciable turbo lag, but without it, I don't reach full boost until about 3500. The 35 shot alone brought me from inconsistent 2.00 60' times, to 1.7's. You could even turn the nitrous off using a hobbs switch (pressure switch) once you reach full boost, but that's not as much fun.

A 2 step allows you to build boost without putting an actual load to the drivetrain. Lets say your 2 step is set for 4000 rpm. You can floor the gas in neutral and the rpms will rise to 4000 rpm. At that point, the 2 step will severely retard the timing, keeping the engine at 4000rpm and delaying the combustion process. This allows the fuel to burn later, and the turbo starts building boost. In just a couple of seconds you can reach the boost level you want, and let the clutch out when the lights are green. The 2 step should be tunable... a lower rpm will build less boost, and your tires will be more likely to hook. A higher rpm can get you off the line harder and faster, but could very possibly result in excessive wheelspin. It makes a heck of a racket and sounds like hell on your engine, but actually causes no damage at all. Using a 2 step is a very common way to launch a stick shift turbo car. It is very consistent as well. Oh yeah, you'll need good tires... no nittos. Get slicks or MTs.
