Injector Limitations

SlyZGuy · 08-01-2016, 08:47 PM

What are your opinions on the limitations of the 600cc injectors that come on the stillen kit? Do you think they should be swapped out at a specific WHP or dependent on certain upgrades? Currently running 9lb pulley, and installing a2a kit and not planning on any future engine mods. My shop is suggesting the si Trim impeller and injector upgrade and I anticipate around 470-480whp with the si or 460whp without swapping and keeping stock impeller.

Depending on fuel the 600cc should be fine. This is also tuner preference. As long as your under 90% duty cycle you will be fine.

I ran 600's at 12psi on my turbo kit with 520whp. You should be fine
