timing for nitrus

[buneke]

the engine is 565 bbc 14.7 to 1 34.5 degrees
first stage is a big shot plate 225hp was pulling out 8
2nd stage is a fogger 300hp hit what should the timing be at this point
car has been 9.40 on motor 8.30 on the first hit pulling out the 8
help is always appreciated thanks

On that first system I'd be pulling out 7 degrees. On the fogger with 300hp I'd pull out another 6 degrees. The fuel pressure for the fogger should be about 5.5 - 6 lbs at 950-1000 psi nitrous pressure.
