ALL variables equal... Whats the flow rate of S1 inj and whats the rate of RC650's?
Thanks
As posted at the top of this page:
If RC Engineering flowed our injectors with their test fluid @ 43 psi, they would rate the injectors as follows:
2003 Injectors - 343.3 g/min = 45.3 lb/hr = 498.3 cc/min
2004 Injectors - 377.6 g/min = 49.8 lb/hr = 547.8 cc/min
So theoretically, the stock 03's are ~500's, and the S1 injectors are ~550's by RC standards. The RC 650's would be...well....650's.

The 630 number I gave was the conversion for 58 psi. Without doing any calculations, it appears as though the S2 injectors would be in the 640 range by RC standards.
