i have a set of these injectors but am starting to question the accuracy of their flow rate. the ones i have are brown. one says 137.5 and the other 136.5. The reason is the following. i have my map maxed out in order to hit 15 lbs of boost. these are my mods anyone else have this problem and this is the first time i have seen brown 1600's.

street ported 13b cosmo
nonsequential twins
npr ic
haltech
walbro
550 primaries
1600 secondaries

 

Well first of all 160 lb/hr = 1680 and these are what most people use when they say 1600. What you have listed shows to be roughly 1400 cc.

 

Hey, I have a cosmo engine also. How did you port the exhaust on the housings? Did you take the cosmo sleves out and put in different ones or did you just reshape the cosmo ones?

sorry for going off topic.

 

left them out.
