New Injectors

[john_V63400]

I have a 01 grand am 3400 W\ RSM 8psi supercharger
I need bigger injectors???

What injectors would be a good choice to increase fuel flow.

If you have a website that would be awsome. Thanks.

well what do you think

[torq455]

if you can adjust your fuel pressure, a set of 26-28# should be fine. depnends if you have bigger cam, p&p heads ect.

Honestly, the best way to tell is to scan and see what your IPWs look like. Based on what RPM they max out at, you should be able to determine your needs. If you grab the 42.5# from ZZP, you will certainly not have any more fuel delivery issues, and should be fine up to 12PSI. However, you should really be scanning first...

Are you using RSM's PCM?

You basically have two options. 28lb/hr trailblazer injectors or 42.5lb/hr lucas injectors. The trailblazers are delphi injectors and will plug right in but they're only about 25% bigger so they will only be good for so much boost. Like tejohnson said you need to see what your injector pulse width is first before making a decision. The lucas injectors will certainly flow enough, but they are more expensive and a slightly harder install because you have to change the plugs on the harness.

60lb is also an option

[AaronGTR]

Well, right... but probably not needed for the boost he'll be running. Maybe if he had a turbo like you... I just figured I'd give him the two options that would work well for his application. Going way bigger than you need just makes it harder to dial in and going too big can make it idle poorly.
