Night Racing @ Barona Tonight

[Alky V6]

First night race of the year. Lots going on.
NE1 cars. (Nostalgia dragsters)
Mustang Club versus the world.
A few fuel cars are expected to show.
An alcohol funny car.
A few Pro Mod.
Fastest street car challenge.
And of course, my favorite, the test and tune lanes are open to anything that comes through the gates.
I'll be testing out a new, and hopefully, more appropriate torque converter for the car tonight, so I expect some whacky first halfs from the car.

4:00pm to 10:00pm.
$10.00 for spectators. Cheaper than a movie and lasts longer.

It was very cold after the sun went down. I had a hard time trying to get the nitrous bottle pressure up where it needed to be. Luckily, even with the low bottle pressure, the hit was clean.
I still have some tweaking of the boost controller pressure curve to do. I over corrected to get the boost low enough to keep the 1-2 from blowing away. Now I have a clean 1-2 shift, but the rise after the shift needs to be controlled better so that it begins to rise sooner after the completion of the shift.
The new TC demanded some very minor tweaking of the fuel map and nitrous timer. By the 3rd pass, we got a pretty clean pass. The new TC allowed me to drop .8 of a second off the nitrous on-time after the transbrake release point. The amount of nitrous on-time after the transbrake is released is now 1.3 seconds. Before transbrake release, .995 of a second.
The new TC is a little tighter than hoped for, and with practically a full second on-the-nitrous before the transbrake is released, launch rpm is reaching 4857rpm/109kPa. Lower than the hoped for 5600rpm/130kPa, but even though, the front tire popped up off the ground, 6 to 12 inches, three times throughout the launch on the last pass.
Wheelie bars were installed for this testing session, since the TC was an unknown factor. I didn't get video, but I believe the car didn't use the wheelie bars on any of the passes.
The impression from the driver's seat was that the car left the line straight, flat and with a hint of the tires popping off the ground. The pull felt very cool.
