[Land-speed] Fuel Injector Testing #2--Adendum

[drmayf]

JG, we are thinking along the same lines with a few differences.   I 
will use my hardware in the loop simulator to run the cars efi 
electronics That provides the drive for the injectors just as if I was 
making a run. I can stop at any rpm and any engine load and gather 
samples. I want to get a set of 8 samples at a time so I can do a direct 
comparison of the fuel mass per unit time or rpm  Instead of volume 
measurement, since injectors are rated in pounds per hour, I will use a 
scale to make a weight measurement on the sample jars. I was thinking 
some pint mason jars, lol.   If I use gasoline it will be via long 
extension hoses outside the shop.  I have a 5 gallon can of mineral 
spirits that may be the working fluid, however. Hopefully less flamable 
and it will also clean the  injectors.

Thanks for th eideas!
