Message I apologize early for the lack of smoky burn out pictures in this post, but Ashley was focused on taking more video at the drags than pictures.

After a relatively painless trip to Uhaul for a trailer rental, I load up the Z on the MT ET Streets, and take an afternoon trip up to Sears Point Raceway's Wednesday night drags. This is bracket racing, which I'm horrible at, but I'm curious what the new build can do.

We meet Rob at Z Car Garage, and he follows us up in his Z32TT for a few fun runs.

We manage to get there in time for make a few practice runs. I just want to practice launching on the MTs, and run two 11.7s at 126-127mph in a row with my 2-step launch technique. After hooking up the ProfecB's remote-switch, I'm able to launch under low boost, then click to high boost once I'm in third gear. It was 90^F with a slight head-wind as Sears Point always has, so I kept the high boost down to 20#.

At 6pm, the bracket trials began. I had just made two 11.7s passes, but the temp dropped down a bit to 76^F. I decided to dial-in at 11.45s, thinking I would run in the 11.5s.

I launch, and the car is alive with the cooler air. Although the absolute air temperature drop was only 14^F, the radiant heat off of the pavement (where the ICs are getting cooling from) I'm sure was well over 100^F before it cooled off. I assume the actual change in intake temp is about 25^F.

The Evo that ran next to me dialed-in at 13.6, so he was given a over a 2s head start. All I have to do is beat him to the finish line, without breaking out (beating my dial-in), to advance. I have bracket-dragged on two other occasions, and have never advanced to the 2nd round. =) He staged, I staged - he went. Finally, I got the green light. As I shifted into third, I hit the remote for high-boost and the Z surged forward. He was many lengths ahead of me at this point. I was going over 100mph in the 1/8th, and reeled him in hard. I figure I could hit the brakes and advance to the next round, or stay on the throttle to see what my (fair) time was. I chose the latter, and broke-out.

As I picked up my slip, the woman escorted me to "that guy" who politely suggested I leave the track until I have the proper safety gear or keep the boost down. What fun is that? ;-)

Here is the final timeslip:

I'll get that video hosted and posted one of these days.
