I'm pleased with the results, you can actually feel the weight difference in just spinning the rotor.

Borrowed some scales from a friend and all my hard work paid off over the winter. I was rewarde with a 2152lb race car with it 2326 with all safety gear and me in it

Finally got back to the 1/4 mile this year after my winter upgrades. Nothing crazy but man the results are impressive
This is at PIR in Portland on there street grudge night/test and tune
I made 4 passes doing some testing on Wastegate pressures and starting to turn it up
Major changes this year are a Glide versus the 80e I had, a2a versus a2w cooler and some random weight savings
Setup is still soft on the launch as Portland isn't usually that great with the prep
First pass. 4lb spring, 3400 launch. 10.46@145
Second pass. 10lb spring, 3400 launch. 9.76@152
Third pass. 10lb spring in low gear, ramped in 14lbs in high gear, 3400 launch. 9.39@165
Fourth and final pass. 10lb spring ramped to 14psi in low gear, ramped from 14 to 18ish lbs in high gear, raised the two step 4000. Car mustard an firstname.lastname@example.org
And to be honest, like how we all datalog in our heads, it could have taken more power in low gear, and a bit more in the top of high gear. I could feel the car nose over near the finish and it may have taken more two step as well. But I was happy it made a clean pass and it drove on to the trailer!
The last pass was a medium soft, 1.5x sixty foot with a 5.9x@131 1/8th mile time. The car picked up 40mph on the back half!
