I got a set of 720cc injectors for a good deal and was wondering if I should run them even when I'm only looking for around 200-220whp at 8psi of boost. Would it make more sense to sell them and buy a set of lower cc injectors? I'm on a stock fuel pump and FPR as well.

 

What brand?
Are they EV14 style?
If so I'd run them.
Always better to be able to deliver too much fuel.
And, with the proper ECU changes you will have headroom for far higher power goals down the road if you so choose.

 

I don't know the brand but they are EV14 and thank you for the advice!

 

I ran 750cc/min injectors for years at about 210whp. Just make sure the injector dead time settings are accurate in your tune to avoid idle quality issues.

 

I've been running 725cc FlowForce EV14 injectors at stock power (136whp) without issues.

 

Assuming standalone ecu.

Most quality injectors will have low pulsewidth data available. Without this it can be hard to get large injectors to idle properly.

That said, 720cc injectors aren't huge, you'll be fine.
