So I have heard that 19lb injectors are tapped out at like 275 hp or something like that. Has anyone heard of this? I know that blown cars are running 36 and 42 lb. But if I am trying to get to 400 engine or 350 whp. Would I need to step up the injectos, what about the pump. My car is a 97 so I would think it would be a good idea to do anyway, but I just figured I would get some input. Id like to avoid swapping injectors if I could.

yes 19s are way too small for 350whp, even NA. If boosting you should go with 36s as a minimum for that power. You will probably need a pump as well. Fuel is one thing you dont want to mess with because running lean = boom and $$$$. Widebands are cheap motor insurance.

I wouldnt advise trying to use the 19#'s for your goal. Are you going boosted? If so go straight to 42#'s even if you plan on low boost. This way it will still leave you room to grow if you want to up the boost.

If your gonna sta NA then 30 or 36#'s would do ya. It all depends on your plan.

Either way get a 255 pump and be done.

Here is an interesting read for you:

This is to determine if your injectors can handle a dry shot, but some of the basics will still apply for what you need. The math equations here are very helpfull.

I was pushing over 300 RWHP N/A with stock fuel pump and injectors. After I changed to 30# and upgraded fuel pump, the pull was a lot smoother but I didn't pick up any power. It was just a little smoother mid range.
