I was just wondering some recommendations on what injector size I should look at. Currently with the stock cam and mods listed, my stock injectors are running at a max of about 90-92 idc. I am planning on installing a TR224 and I suspect that will max out the stock injectors. I am thinking of getting some regular 8.1L injectors. Do you guys think this is a good idea or have any other opinions?

 

you could bo with the 8.1L marine injectors, i think they are 42# ers......

 

8.1L truck injectors will be plenty unless you plan on nitrous or FI or a built stroker

 

Yep

 

flywheel HP times 0.5 divided by 8 cylinders, times 1.1 = injector size, divide by 0.8 for safety factor = injector to be used.

 

if you are going to add in a safety factor, you should multiply by 1.2 instead of divide by 0.8 so you get a larger injector number that you need instead of a lower number and chance going lean

 

Both do about the same thing for saftey factor. Dividing by 0.8 is the same as multiplying by 1.25

Currently I am not "planning" on additional power adders, after the cam, due to lack of funds, but you all know how that goes. If I found a good deal on a N20 setup and happen to have some extra $$ I might do it. I have considered the Marine injectors just to have a little extra I just didn't know if it was worth spending 2.5 times the cost of some regular 8.1L injectors at this time. Man if I could find a better price on the marine injectors it would make this decision much easier.

 

if you divide by .8 you will get a higher number than multiplying by 1.2

my stock injectors are only seeing 55%idc on a 100shot
