To convert cc / min to lbs. / hr. - Divide by 10.5
720cc=68lbs
750cc=71lbs
720cc=68lbs
750cc=71lbs

i suggest getting them flow tested as they are not all too accurate especially when getting that big of an injector. My buddy just tested his denso 720's and they all flowed over 800cc at 43psi.

John, actually, that method only gets you a close estimate to the correct size. The much more accurate equation goes like this: [(lbs./hr) x 60] / 6.177 = cc/minL2RTSiAWD said:

lb/min caculations have everything to do with psi and base fuel pressure. so its more complicated then that.
