i have a set of precision injectors laying around that i can no longer remember what size they are....they are either 770s or 880s i dont remember what they are


all that is on the injectors are the numbers 18743

thats all i can find on them...ill post pics if need be

 

post pictures, are you sure there RC? Any rc injectors ive seen or used always has the model numbers stamped into them ie: peak&hold 1000cc's would say PL4-1000H

 

they are precision injectors....there is no stamping on any of the injectors....just a number code on them. i have been looking on precision's site and can not find ****

 

my bad idk why i read RC lol, stupid me, have you tried calling precision?

i can give you precision 680's from crome, which would be ballpark batt offset values for the injectors you have.

Volts ....16.....14.....13......12......11......9......7
INJ MS...89...1.05...1.13...1.22...1.36...1.84...2.55

i found online for precision 780's

Volts.....15.....14.....13.....12......11.....10
INJ MS...96...1.05...1.13...1.22...1.36...1.56

From what ive read online the 880's are same batt offset as the 1000's
