* Bottle Temp = Bottle Pressure

NOTE: I recommend a bottle pressure of 950 psi for best performance.

Fuel Pressure
PSI ex: 40 (EFI: ~38-45 Carb: ~7psi)
(info only needed if you are using a 'Wet' setup)
Nitrous Pressure
PSI ex: 1200 (900-1200 is optimum pressure)
(info only needed if you are using a 'Wet' setup)
Nitrous Jet Size
"Thousandths of an inch". ex: .030
(Will calculate Horse Power(HP) rating for jet)
Number of Nitrous Jets
Fuel Jet Size Needed:
" Thousandths of an inch" or mm
