914World.com _ 914World Garage _ Injector flow rates?

Posted by: newto914s Sep 19 2005, 10:01 PM

My heads are running a little hot and since I can't find any vacuum leaks and my injectors are miss-matched(two green stock 76, and two blue volvo injectors-280 150 024) I thought I'd check their flow.

All four appeared to have a nice spray, here are the numbers I got. This is over a 5 second crank, cold engine, and my Mom as the assistant(so figure in with the margine of error

#1) .85ml out of 7 pulses
#2) 1ml out of 8-9 pulses
#3) 1.1ml out of 8 pulses
#4) 1.15ml out of 9 pulses

#3&4 are the blue injectors, I was going to order some new ones to have a matching set(greens), but mabye I shouldn't if they're flowing more.
What do you think?

OK, I should have done a search first, their are a number of posts that show the flow rate. 380cc/min.
How would I change the numbers that I have to compare them to cc/min

Also, if the injectors are close, how important is it that they are matching(I guess I'm thinking in term or resistance)
