recommended shot
recommended shot So ive had a nitrous outlet lt1 nozzle kit for a while now. Anyway, looking for opinions on a safe shot on my setup. I do have a racetronix 255 pump with hotwire setup. My motor made 438/419 on a dynojet dyno. Question is, would a 100 shot be safe with the current setup? or should i hold off until i buy a dedicated cell?
That pump will support at least 600HP on motor. That leaves at least 100HP of motor fuel and nitrous uses less fuel. 50lb/hr for 100HP on motor and 32lb/hr for 100HP of nitrous. You should have enough for about 300HP shot. Safer estimate would be 200HP shot. Super safe bet would be 100HP shot will be fine.

Roughing out fuel system numbers. 50lb/hr per 100HP for NA motor, so 800HP motor would need 8 injectors a 50lb/hr for a total 400lb/hr of fuel. A 600HP motor will need 300lb/hr total fuel. This is what I use to roughly plan out my fuel needs on a motor I'm building or tuning.
Nitrous is different (at least people who in modern times) it takes about 32lb/hr for each 100HP. So, if you take that 600HP motor and want spray it with 250 shot. You would devide the 600 by 100 to get 6 and multiply it by 50bl/hr x 6 = 300lb/hr total. Then you divide 250 by 100 to get 2.5 and multiply it by 32lb/hr x 2.5 = 80lb/hr total for nitrous. Add the two together an you get 380lb/hr to run that motor. Add you 20% or so for room to grow and to keep the injectors out of 100% duty cycle.
If you can remember that you can do it on the fly or just go here and use their calculator. https://www.rceng.com/technical.aspx
