I participated in this even again this last weekend. Truck wasn't 100% ready from the last round of changes I made but I have been working a lot of over time and didn't have all kinds of time to work on it.
Here is a run down of the last race...

My goal this race was to run 170MPH to beat my last race best of 165.6MPH. The only changes to the truck are listed below.
-CTS-V 4 piston brakes front and rear
-18" Z06 wheels compared to 18" wagon wheels (same tires though)
-32 spline Ty output on the t-case
-added a second meth nozzle
-actually cleaned the truck the morning before we left
-new windshield to keep Renz happy
I didn't do any tuning for the second nozzle prior to the race and the last race I was at a 98% duty cycle on my faster run.
Here it is nice and clean...
Almost there with the convoy of my friends cars
In line for the first race
A lot of fast cars out there
My first race was against my buddies 13' GT500. During the race at about 150MPH i hear a snapping sound and saw a black blur go flying past my drivers side window. Finished the race running 160MPH and found this...
The track guys were nice enough to pick up the pieces for me
I grabbed some tape out of the tool bag and got to work. I wasn't going to let that stop me from racing
I raced again and ran a new best of 166.4MPH. This was only at 13psi and 18* of timing. Over the next couple runs it when I started having real problems. The solenoids on my Boost Leash boost controller went out and would not let me make any more boost. I already had my biggest spring in the wastegate which netted me the 13psi with the controller off.
So I pulled the controller and started to play with my lines and other springs. The only combo I could get to work netted me 8psi (too low!), 13psi (still too low!), and 26psi (way too high!) After the 26psi fiasco I put the truck back on the trailer and called it a day. Due to my over extended fuel system my AFRs were 12.3:1 at the 26psi. I did turn my timing down to 12* prior for a safety measure. The engine is not making any funny noises and I hoping running E85, dual meth nozzles and low timing saved the motor. I will look at it when I have time in a few weeks. The 2-3 seconds I was at 26psi was absolutely amazing though!
Here are some pics I found on instagram of the truck
While this race was kind of disappointing with the boost controller issues, I still had fun. My buddies GT500 ran 159 spinning a lot and my other buddies G35 ran 170 starting in 2nd due to some shifter issues. The new brakes were freaking awesome and stopped 1000000 times better that the last setup. Hoping to get out and run this event year again. As of right now, I'm going to focus on some 1/4 mile racing!
Over all my runs were 158, 160, 161, 166, 162, 160, 115(aborted 26psi). No two races were with the same setup.
I have some videos but have to edit them so might be a while
