7/19/2009 California Speedway

Seems appropriate to start a new page with Cal Speedway. This time at Redline Time Attack. Real quick notes:

• New wheels and tires, just purchased this week for the event. OZ Superleggara, 18 x 8" with Kumho Tires. Tires were definately the week point. The tires I had counted on, Bridgestone S-03's, fell through.
• Ran a 2:03.13 in practice Saturday, six seconds slower that my best NASA time on R-compounds.
• Turbo housing cracked during the first practice session Sunday, so no official Time Attack run time was posted.

New Projects and Issues:

• Pull the cold side housing and repair or replace.
• Need aero and belly pan installed.
• Transponder was not working. Check wiring.

Buttonwillow Audi Club Prep

• Turbo housing repaired by Twins Turbo
• Belly pan bracket installed so pan is ready to go back on
• Reinstalled wiring for transponder. Properly hooked up into the main circuit with fused link.
• Added two new Dzus fittings into the bumper for additional strength
• Moved wiring and N75 away from the heat
• Rerouted hoses that were rubbing
• Adjusted the brake pedal to master linkage to eliminate dragging and/or double pumping issue

Current issues

• Rough idle and flashing check engine light. Suspect it is fuel related. Pulled codes with Dave Kan, missing on cylinder 2&4. Swapped plugs and added some miracles in a can, heat and injector cleaner. Also scheduled it to go into Beach House Imports to be looked at. Needs to get smogged.

Fuel Issue Resolved 12/31/2008

Beach House could not find the problem, although they did find a boost leak under the intake. The R&R for that was $300. The car barely made it back home though it ran so poorly.

Talked to Jeff Moss and he suggested looking for a leak at the injectors by spraying carb cleaner. With that technique I found #4 injector with a huge leak. Pulled the rail and found that one of the injectors had lost it's clip and dropped too deep into the intake causing a leak. The injector was stuck in the intake and it's nylon washer dropped into the intake/engine when the injector was removed. The repair then required that the intake manifold be removed to retrieve it. Also replaced the injector.

Finally running good again today! In addition I bought a replacement for the old cracked junction box.

• Replaced junction box on R.H. side of engine bay.
