Good help finding what size injectors to use for each setup.
I found something,to determine the right size fuel injectors for each setup.
Very important you know your boost pressure,fill in the chart and the proper size injector is given.
I did some testing riva x-upgrade 12 psi
1 psi added = 10 hp
stock hp x model 255 hp
stock x-charger = 10 psi
255 hp + 20 hp (2 psi upgrade from charger) = 275 hp
stock fuelpressure 58 psi
3 injectors used
brake specific fuel consumption 0.50 ( charts says 0.55-0.60 this doesn't work just keep the 0.50)
Now fill in the fuel injector worksheet.
Outcome required injectors is 49.62 riva claims 50 lbs .
I also did the test for the 215 hp engine,outcome the same as oem size .
This really works ,as long as you now the extra boost your getting from your new supercharger upgrade,you can find the right size injectors.
I use it only as a reference,and a rrfpr can be added to get the right afr,but still its a big help!
