My own calculations/notes
200 hp guess:
12.5 AFR, VE 81, 3200 lb race weight, 15 psi of boost, 25 lb/min air from turbo, 34.2lb/hr injector at 87.5% duty cycle, 14.6 @ 92 mph
To make 230 hp:
12.5 AFR, VE 81, 3200lb race weight, 19.6 psi of boost, 28.75 lb/min air from turbo, 39.42lb/hr or 35 lb/hr 100% duty cycle, 14.01 @ 97 mph
15.3 1/4 mile time equates to a 3200 lb car race weight making an actual 175 hp. 185 hp would give a 90 mph trap speed. May be limited to a 14.3 @ 95 with stock parts 215 hp.
