aarang Posted January 9, 2003 Share Posted January 9, 2003 I know this is a simple question, but how do you convert cc's to lbs/hour on injectors? I have some merkur injectors @370cc each. Ford Mosport sells 8 new injectors for $200 in a variety of sizes that would fit right into the Z manifold. They look identicle to the Merkur ones. I might try these instead.

blueovalz Posted January 9, 2003 Share Posted January 9, 2003 Does a 370cc injector inject 370cc of fuel/minute?. There are roughly 3785 cc/gallon. Fuel weighs roughly 6.6 lbs/gallon. This means that there are about 573cc/pound of fuel or 1cc/.00175 lbs of fuel. Assuming 370cc of fuel/minute, this equates to .645lb of fuel/minute, or 38 lbs/hour. I'm not an injector kind of guy, but does this sound correct? Any FI folks out there that can help? Quote Link to comment Share on other sites More sharing options...
Kennysgreen280zt Posted January 9, 2003 Share Posted January 9, 2003 according to Max Boost by Corky Bell..... CC/minute = lbs/hour x 10.5 SOOOOOO your 370cc injectors come out to 35.2lbs per hour. Assuming I know how to do 9th grade math that should be correct HTH ~Kenny Quote Link to comment Share on other sites More sharing options...
blueovalz Posted January 9, 2003 Share Posted January 9, 2003 Hmmmm. I wished I knew where I went wrong. Considering that 92 octane is 6.4 lbs/gallon and 87 octane is 6.2, I still only get as close 36.42lbs/hour with wimpy gas. Quote Link to comment Share on other sites More sharing options...
Pop N Wood Posted January 9, 2003 Share Posted January 9, 2003 How do you know that "CC" means "CC/minute"? Quote Link to comment Share on other sites More sharing options...
SleeperZ Posted January 9, 2003 Share Posted January 9, 2003 Originally posted by Jim Powers:How do you know that "CC" means "CC/minute"? It does. The original poster just failed to put in that assumed detail. The metric flow rating for fuel injectors is in cc/min. Quote Link to comment Share on other sites More sharing options...
dot Posted January 28, 2003 Share Posted January 28, 2003 I might be wrong cc/mi X .0158503 = gal/hr You also might consider the impedence of the injector. A change to low impedence injectors could burn out your ECM if it was not designed to drive them. Quote Link to comment Share on other sites More sharing options...
