I am trying to figure if 60# injectors are to much for my setup. I want to get 42 but if i upgrade my motor latter i dont want to buy injectors again latter. My question is can i run 60 # injectors with my setup and dont have to worry about it being to big , like running rich or fouling plugs here is my setup.

Stock Lt1
S-trim 7 #s of boost
1 3/4 long tube headers, ory pipe, 3 inch cutout, flowmaster catback
255 walboro fuel pump
pcmforless tune
3.73 gears
peformabuilt level2 trans, 3000 stall

 

I would check with Bryan since you will need to have the PCM reflashed to correct the injector constant. They should be fine but he may advise you differently.

 

ok i will call him tomorrow.

 

My 60# mototrons worked fine on the stock motor.

 

Go 60s to be safe, I thought 60s would be fine for my setup and on 8psi I maxed mine and thats on LS fuel pressure so theyre like 70's

go big or go home... the 60 will work fine.. then you got room for more power to be made with them..

 

8 lbs on your setup is a bit more airflow than what a stock LT1 will see.

 

fine 8psi on my old 383 LT1 583rwhp hahahaha

Still tho once he gets use to the boost he will upgrade like we all do.

called today and found out that the 42s are good to 500 to the wheels. But can run the 60s if i want also.

 

500 to the wheels on a NA application probably...

He knew i am going supercharged. But maybe he got confused?
