I am getting a tune soon and I have a 3.0 pulley, a header and downpipe, do i really need bigger injectors?

 

no i think you can run 3.0 on stock injectors. But it wouldn't hurt to get some 42s.

 

i heard at our cars with the stock pulley run full injector campacity at 11lbs psi so we actually overrun the injectors stock so yes for a 3.0 you actually need 42s from what i have read

 

im wondering the same

 

just get them
more power and keep you safe

 

Get 42s just to be safe....

 

thanks guys!

 

You overrun the stock injectors with the stock pulley (~120 IDC).

 

so if we end up maxing out our 42lb injectors with say a 2.9 thats kind of okay cause we max out stock to begin with....right? I know its not good but if it happens then it happens...

 

You shouldn't be maxing the 42# with a 2.9" pulley. The problem you will run into is after about 6.5k rpms, you will lose a lot of control with the 42# injectors. Ask Area47 if you want more details. He can explain it better then me.
