I went back and forth trying to choose a cam. I was on the fence between the Speed Inc tu2 and the Comp XR281HR. I finally picked the later. 




As I was doing the install, the lifters would not stay in the trays so I was using a magnet to lift them up while I slid a dowel in to retain them. I got to the last 3 lifters when the magnet broke off inside the motor. I did what I had to do and pulled that head off and got everything back together the way it should be. 



Also on this round of upgrades is a new windshield and I got new Tokico blues installed up front. The old shocks were a little blown. 

 



Lastly for this update got some logo's donated for the car. 



The goal for latest sprint to get the car ready was a local Import vs Domestic race named All Out Call Out. I had taken the car to work to make sure all was good but had no time to really dial in the tune on the smaller motor. I got two runs on the new setup in the test passes before the real race to tune it. On the first run I had the boost controller off and with 4psi it ran a 12.1 @ 115 with a 1.9 60 ft. Run 2 with the boost controller set the same as last year the new setup hit 18psi (down 6psi) and ran 10.3 @ 144mph (only down 3mph from last year) but still a weak 1.8 60 ft. It is not building boost on the line like it use too. Next up was the first round of eliminations and I'm facing Scott in the Vega that I ran in No Bull last year. I had adjusted the Ams1000 to push some more pressure into the top port of the wastegate and added some timing. He left the line with a much better reaction time but I was playing chase. Still no real boost on the launch but I came on much quicker and harder. I lost both my tach and shiftlight but still shifted flawlessly. Unfortunately the car didn't stick with the increased boost and I found myself in the middle of a wild ride trying to keep the car off the wall. I succeeded in saving the car but lost the round with a 12.3 @ 110 mph.
