Well was able to run 13.1 at 110 mph on 91 and 10psi of boost even though the track conditions were so bad that the adjusted alt was 3500 ft at the CA speedway. Sad part is that the car still leaned out in 3rd gear even with the maf unplugged, I guess its time to replace the walbro fuel pump.

Next stop is Waterwagons, which means I will have hit 3 major 1/4 mile tracks in 3 weekends with 2 of them being big audi/vw events. :)

Did I ever tell you how much your turbo scares me?

Why are you running 91? I'd expect you to be out there with race gas just stompin' on people.

Well I cant run more then 10psi at the track with the race pipe installed. The car was tuned for 20-22psi of boost on 105 octane but with the cat. As you can see I am flowing even more air now with the race pipe at just 10psi then I was at 20-22psi with the cat.

I log the car while I run and was able to hold 18-22 degs of adv timing on 91 while running 91 octane. Just sucks that the car runs lean in 3rd gear getting up to mid 14:1 AFR, so most of the time I have to let off the throttle and coast to the finish line. Once I get this all fixed I plan on pushing it to 25-30psi on 110-116 octane.

Air temps were about 95 degs, high humidity, pit surface was 114 and track surface was even hotter. It is the high temps and high humidity that hurts the most.

Can I get a little more info on your setup? Rods/pistons/etc...

I should have gone bigger than the GT28RS. Damn.

Custom chip and EBC. My goal was to hit 500+ hp while still running a chip and still running as a dbw car. Now my goal is to hit 500+ whp while still running chip tuning and EBC only.
