Rather I stalled it or flashed it with just the gas pedal it, just shy of 1,700rpm is all it'd get. Right around 1,680rpm on the stall speed. It launched better stalled up with about 40% throttle to keep air speed up. It'd just barely chirp the tires when I let off the brake on launch.

Even with all the milling the compression is still only a measured 8.37:1.
