Reference: Injector flow rates Hi all,
I know everyone has anguished over injector flow rates at one time or another. I came across this website with actual flow rates for many, many injectors. I have no affiliation with this company, just a good reference.

Enjoy!

Cool. However, it just says cc @ pressure. Is that cc per minute? Per hour? What's the conversion to lb/hr?
FYI: My SVO 30# injectors are part number 0280 150 945. That site says that they flow 312cc @ 43.5psi.

theres a sticky in the fuel and injection section already for fuel injector calculator also, maybe post this in there and ask it to be a sticky also. but this is the same thing

Wouldn't it be more accurate to find out exactly how much your fuel weighs? And doesn't that depend on the type/octane and temperature?
'cause if I use 6.25 gal = 1 lb (assuming I'm using 87 octane at ~ 70°F), then the formula wouldn't be using a simple 1 lb/hr = 10.5 cc/min.
Instead it would be: Total cc/min = x (lb/hr) * 3785.4118 (cc) / 6.25 (gal/lb) * 60 (min)
Now, the weight isn't very accurate. Google isn't very accurate either it seems, but using those figures I get 1 lb/hr = 10.09 cc/min, or 30 lb/hr = 302.83 cc/min. Apparently premium gasoline is close to 6.35 gal = 1 lb, which is 298.06 cc/min for 30 lb/hr injectors... FYI, I'm finding everything from 6.0 gallons per 1 lb to 6.5 gallons per 1 lb of gasoline. I think I'm just going to fill up a gas can and weigh my own damn fuel for greatest accuracy.
Good thread though.

Injector delivery is really volume based and unless
you are using gasoline to test, the lb/hr would be
off (unless you correct for gasoline/reference fluid
densities). Most pros prefer to use the reference
fluid it seems (which does have very carefully
measured attributes).
