Re: Considering Injector Change..



   Fuel vs Hp guidelines:  24lb to 450 Hp , 30lb to 550 Hp, 36lb to 650 Hp.
   Choose components wisely and  in matching quantities.
   LT1 Fueling is very well done as GM sold the vehicle, with respect to NA
   calibration, You should be able to see 12s with stock injectors, everything
else with the vehicle being up to speed. NOS is a completely different game than NA, leaving stock injectors out of the game. Make a decision and stick
   with a PLAN. Again , choose wisely before taking the plunge.

I have a currently stock '94 LT1.
I am considering changing out my injectors for larger ones. The ones I have
have over 140,000 miles on them and are likely due to be changed. I am
flowing a little more air then stock and I figured being able to throw more
fuel at the engine would be good. Especially if I decide to go with a NOS
system I want the injectors to be able to handle the pressure.
I understand I have 24lb injectors now. If I go to 30# or 36# injectors I
won't be hurting anything will I? I AM using LT1 edit and can change the
program to reflect the added injection.
I am guessing my duty cycle will be less that way.
But can someone tell me the pros and cons to doing this change before the
engine really needs it?
I figure though that if I am going to buy injectors I only want to buy them
once.
