Size of the injectors depends on the power you want to make. The GTP from Michigan yesterday had 60's on corn make 340 whp. Injectors were at 80% duty cycle.
Might as well go with 60's out of the gate......
Would you say 60s, fuel pump and a what, 3.1 pulley...? And im in business?
If i threw 60s in now, would my pcm still be throwing the same fuel mix on pump gas? Or do they automatically use more fuel cause theyre bigger?
I guess what I want to know is-
If I installed injectors and a fuel pump, drove it up to columbus for a tune and switched my pulley then... Does it work like that?
Is there a thread containing this information? Ive looked with no avail. If there isnt, THERE SHOULD BE. Unless its just common knowledge and Im just way out of the loop. Thanks guys.
Gotcha. Thanks for the reply.the computer has to be told when you change injector size, if you threw in bigger injectors, it would shoot more fuel, for example if you had 30's in and you installed 60's it would shoot approximately double the fuel at the same pulse width
the computer can compensate a little for the bigger injectors by adjusting its fuel trims, but not enough for a set of 60's where the 36's were, just bring them with to install them when you get it tuned.
