i bought a set of used lt1 injectors and question what lb/hr rate they are. the numberon the injector body is 17121068. i would like to know before i tear apart my tpi.(what a pita.) can anyone with injector knowledge please help. i've searched and searched to no avail. thanks.

 

If they're from a stock LT1, I believe that they're supposed to be 24 lb./hr. Don't quote me on that, though--I'm not an LT1 expert.

 

they are 24lb

 

If you want to know the EXACT flow (not the rated flow) and want to make sure they all flow the same, send off a note to Rich at Cruzin' Performance. For a paltry $11 each, the set will be returned cleaned, flow-matched, and have good 'O' rings, caps, and clips.

 

the set i recieved were guranteed and good working order. pulled off a good running 97' Z(upgraded to larger injectors). i did put them in and them worked great. even with changing the prom settings at first the computer has a slight floating idle. then adjusted and worked normally. thanks again.


i will send off the next two sets i'm getting in to rich. thanks alot guys.

 

I have a set of injectors with the same number but on a couple websites it says they are 21.1#, can anyone verify for sure what they are? What's your source? Anyone know a way to contact Rochester to try to ask them directly?
