The effects are documented. I had a turbo car that would eat a thrust in 1 pass. I mean chew it right off to the effect of .030" after a pass. I made adjustments and we went to the track to test. The static cooler pressure was intact and we were ready to test.
We made 3 passes which consisted of spoolup , stage , launch but no gear change just ran it to the shift point and let off.
Checked the thrust every attempt and it was fine. There were some spikes on the launch but it seemed ok.
The next pass was a full pass and it was all over. Crank was done .017"
thrust from .008" Better than .030" but not fixed.
This was a glide and the time spent on stall after the gear change is greater than a 3 spd.
