I'm with you brother. My 60' times suck. I'm not so worried about the tranny, but I can't seem to get my launch right. I think that I just need more time behind the wheel on the strip. Bandimere has been incredibly sticky when I've been there, and even with street tires I was dead hooking with a 4000rpm launch (7000 rpm redline). I think that I need more right pedal and more clutch slip off of the launch. Damn drag racing isn't as easy as it looks.....especially with a manual clutch. I have my first 3/8 mile circle track drag on the 4th. That should be a fawkin blast.

You both can setup a 2 step device. For ZX-Tex, it'll make boost off the line. For you, it'll let you leave flat on the floor. Drag racing takes just as much skill to do right then most other sports. Time, patients, practice, finesse, and a wad of cash your just looking to burn.

It is a 2nd revlimiter that you can hold the engine at while at the tree. You can then put your foot flat on the mat while it holds whatever rpm you set it for. It also makes powershifting a bit easier on the car since when you clutch it, it goes to the lower rpm the 2 step devise is set at.

Yes I do, or at least flat shift which is working great. If the clutch is in, and the throttle is at WOT, then it rev limits at 4500 (settable). For upshifts, just keep the throttle at WOT, push in the clutch, and shift. The BOV does not even open up. It takes getting used to not lifting the throttle for upshifts.
I have not played with launch control yet but maybe I will. The Adaptronic has it.

Either one. You can cut spark, fuel, or both. AFAIK with a cat you have to cut both since just cutting spark can cook your cat. No tail pipe flames, bummer.

Ive tried both, and the car reacts exactly the same way for either one. I thought spark cut would make flames and/or sound like antilag (thing big turbo supra) but nah. Just a slow bounce off the preset limit.
gets the job done though
I was able to get 3-5psi off the line

Launch control now working. Yesterday I turned it over to the tamed racing driver who did a quick 1/4 mile run on the abandoned airstrip. On street tires, and according to Trackaroo Dynomaster, with a lame launch (3.15 sec 60 foot), the Stig still managed a 14.18@101.8. So a better launch, some stickier tires, and some drag strip pavement should get it into the low 13s.

Video of the car on the dyno. This shows how the load dyno holds the RPM as the operator goes to WOT. You can hear the turbo spool but the RPM stays constant before he releases it for the ramp run.
