If I may quote the Nov 97 Turbo+Hi Tech Performance Mag. page 98+99
C.R B.S.F.C.
6:1 .7
7:1 .64
8:1 .59
9:1 .52
10:1 .47
11:1 .45
12:1 .42
C.R. compression ratio
B.S.F.C.-how many pounds of fuel to make one horsepower-sometimes
refered to B.M.F.C.
Desired Inj.Flow= HP x (B.S.F.C.)/ (no. of inj) x.8
If you want cc/min multiply the above by 10.5
This .8 is interesting, it's to limit the injector to 80% duty
cycle, now I've read here (in the archives) that the lb/hr rating
of a injector is figuered at 85% duty cycle, and have read that
it is 100%, can someone that can quote a source, and clearify that.
For really high rpm, I'd think disc type would be about your best.
