What's your target horsepower, and how many injectors can you fit?

blowncoupe,

Did you see this: http://www.megamanual.com/v22manual/minj.htm#size

It gives 44.1 pounds per hour as the minimum required flow rate for 600HP and 8 injectors. There is lots more info about injector selection there too.

High impedance is a lot easier to set up; they put out a lot less electrical noise.
