Help me figure out my injector size

I am trying to figure out about what size my secondary injectors are in my turbo II. The previous owner is not sure. I searched for different conversions but can't seem to figure this out. Im not sure if its even possible to figure it out with little information.

I am running haltech on a hybrid turbo (similar to BNR stage 1) at 13 pounds at 7500rpms, my secondary injectors are running at 6.25 MS.

I know that is not much information, but I know some of you all are smart dudes and might be able to find an equation to help me out.

Please enlighten me.

I found this thread, using this information I found my injectors are running 78% duty.

Now I just wonder what cc/min my injectors are. Can't be very big.

Only real way to tell would be a flow test.

But do you have any pics of them?

+1 on the flow test and cleaning. Winter is coming, take the car down for a couple weeks and send the injectors out to get cleaned and flow tested. They will come back like new and you'll know exactly what you have and you'll know they are good. You can get all 4 done for $60-$80.

Agree with the above. You can get a good idea of what they are supposed to be by getting the model number off the side of them and referencing here...http://injector-rehab.com/kbse/flowrates.htm
