I'll get a few miles more miles on it and switch to the 75 and get it dialed in with that pulley and probably run about 12 lbs to start the year out.

We were running out of low pressure fuel pump before we added the BAP and that was with the LT4 in-tank pump. Once we added the voltage booster with the in-tank pump, we were perfect.
Yes.
85mm - 8psi
80mm - 10psi
75mm - 12psi
70mm - on the bench until summer...out of injector.
Since you are spraying alky, you can probably demand less fuel...but once you have the in-tank and voltage booster, you won’t need alky until you go to the 70mm unless it's just for cooling since you make consecutive runs.
