i think the 04 version got a bigger injector when they went to the returnless fuel system. I think it is around the 28 to 30 range.

FWIW, my stock IFR table is as follows (in my 04):

0 vac through 80 vac.

24.49 24.62 24.8 24.93 25.11 25.24 25.36 25.55 25.67 25.79 25.98 26.1 26.23 26.48 26.66 26.91 27.1

I guess I have no idea what sized injectors I'm running. I always assumed they were 24's.

Those are g/sec IFR values??

25.11 g/sec = 199.3 lb/hr

Them 'er some bigguns, ayuh.

(or did HPT allow lb/hr finally? )


BTW Stock 03 injectors are 3.18 g/sec with the regulator, so 25lb/hr @ 58 psi

During one of my last few HPT upgrades, my IFR tables mysteriously got converted to lb/hr.
