I am hoping that 550 injectors will be enough. That's what I have in there now. Any objections?

Larry, your injectors are really 500s.

Deatschwerks rates the G/Z injectors at 3.5 Bar, which is the stock fuel pressure on these cars. At 3.5 bar, they flow 550cc/min. But at 3 bar, which seems to be the industry standard for reference, the Deatschwerks 550s only flow 500 cc/min.

So if you are to compare these injectors to an RC 550, they don't flow as much......

of course, you can always jack up your base fuel pressure about 10 psi and make up for the difference.....but then we get back to how fuel pump lose flow at higher pressures. It is a vicious cycle...

I suggest getting bigger injectors and running less fuel pressure!
