Had some good runs today. The larger shot size was not an improvement. After a little work on the fuel table, I was able to at least match the performance of the previous shot size. I will be going back to the 364 shot.
Now that the limit of what the nitrous could do for me has been found, it's time to work on the boost control curve. There's a little work still to be done there.
With the tire pressure at 10.25 psi, the car smoked the tires from the 330 ft mark to the 660 finish line. The car did not lose complete traction, but tire shake was felt as I crossed the finish line, and when I checked the rearview mirror, tire smoke. Watchers also confirmed this.
With no changes to the boost control, I dropped the tire pressure to 9.0 psi on the last run and picked up one mph and the car felt much more stable.
The rpm drop on the 1-2 shift was 900-1200 rpm, depending on the shift point rpm, 6950 or 7250 rpm. This was at a leveled boost pressure of 200 kPa.
The rpm drop on the 2-3 shift was 650 rpm. Boost pressure during the 2-3 shift was 274 kPa.
Rpm across the finish (660 foot mark) was 7350 at a boost pressure of 280 kPa. The slip across the finish is much higher than the previous TC where I was crossing the finish at around 6700-6800 rpm.
