Default Injectors sizes
Hi was looking for some help for some injector sizes for my build. Are the rdx injectors enough or do I need bigger? Running a 2.4 stroker that is being put together currently. Any input would be appreciated.

No need to upgrade at all. Stock injectors should be more than enough...

Stock injectors are good to 300-310whp in my experience utilizing them with a base kit supercharger.

At stock fuel pressure and 100% duty the stock injectors theoretically supports up to 233whp.

Great injectors. I ran ID1000 on the stock engine for some time during my FI transition. Runs good as stock.

I made 240whp and my injector duty cycle doesn't even touch 70%.... buying injectors with a n/a setup is a waste of money

What ever it takes. Fuel pressure is free. I run 85psi idle pressure on my stock injectors. You wont need to run that high if you can increase injector duty, I cannot because I'm running a factory ecu.
