Would 46lb Injectors be overkill? I plan on running about a 100 dry shot.

Not overkill at all, I am having no problems whatsoever with 42's on my stock LS1, you should be fine with yours. If your sig is what your spraying with, I say you would be on the edge with a dry shot (100+) with your 28's.

i have 36 lb pound injectors-bosch i make just a tad under 550 bhp on a 175 n20 hit-zex wet system-

the computer says we are at 63% duty-i am not to good on how to work the duty cycle rule-if their is one-

i plan to up the anti to 250-300 hit-

will the duty cycle go up or since its a wet system and has its own fuel supply-will it affect-

i have a walbro intank pump already or will have i have to change the injectors because the n2o will raise the hp?

rather ask a silly question before hurting something-

Thankyou-

When using a Wet kit, the fuel comes from the nozzle which is jetted. Wet kits are not affected by the injector size.

A dry kit generally uses the MAF to tell the PCM to add fuel via the injectors, therefore injectors play an important role in Dry kit planning.

The general rule of thumb is 85% duty cycle is the most guys like to run, does that mean you can't go to 100% or more?? No, you can, buts its is said to shorten the life of the injectors if its going "Static" (holding itself open) alot.

My 99 LS1 w/ 26 # injectors was at 106% duty cycle with a 50 Shot of Dry.

I havent sprayed the car with neither dry or wet kit with the new motor. Just making sure it wasnt too much.
