Hey guys, I need some help. I bought some 8.1 marine injectors for my motor, but can't use them till I get the right #'s to put in the IFR table. I have LS1 edit. Thanks for any help you guys can give me. I'd like to put the injectors in before I go to the track on Friday night.

 

Just pull an 8.1L OS and copy the injector values over. What year is your truck?

 

Check out redhardsupra's injector sizing spreadsheet. Can find it on his blog at: http://redhardsupra.blogspot.com/

 

My truck is a '00 model with a 5.7 ls1 swap in it. What is 8.1OS? I wish I had gotten the regular 8.1 injectors, but I felt like I got a good deal on the Marine ones.

 

ttt, someone must have these injectors

 

You want the g/sec flow for 8.1L marine injectors... is your fuel system vaccum referenced?

 

41.98 is the number across the board if you are vacuum referenced. For 05 and up you would have to use the spreadsheet. The 41.98 is at 58psi (stock rail pressure) and I use HPT I don't know if edit would be the same.
