LT1 fuel pressure

The formula for determining a different injector flow rate by changing the fuel pressure is :

(Square root (New Pressure/Old Pressure)) x Old Flow Rate = New Flow Rate

So if you go by Dans' combo where he stuck in LS1 injectors (24lbs@58psi) and he lowered the pressure to 43psi . The rating would now be (21lbs@43psi) . Basically a wash compared to a stock LT1 injector which is (22@43psi) .

Its important to know what pressure is used when comparing injectors
