I'm seriously considering getting higher flow injectors to be able to run straight E85 with no CELs.
Figuring out what the injectors are, and what higher flow injectors are compatible, is no easy thing.
It seems that the stock injectors are Siemens part number 12790827. I've seen them quoted at 355cc/min, 32#/hr, 34#/hr, and 36#/hr. Not sure which they are, and I'm just going to assume 36#/hr.
These injectors are also used in the supercharger Cobalt SS.
Just doing the calculation, at 210 hp, with a .5 BSFC and 80% of capacity, you need 33#/hr injectors, so 36 seems right to me.
Now I need to figure out a compatible higher flow injector. Just comparing air-fuel ratios between gas and E85, I need about a 55# injector. Maybe a little less, since we know that the Saab injector is optimized for E10, not gas.
