Most of us at times have done something similar. In the end, it never saves money. It costs more money and time.

I would go with 80lb injectors if it was me.
UnderPSI,

I haven't ordered them yet. All options are on the table. Can you have too big of injectors, to where you can't dial them down at idle? Seems a legitimate question....

I'll discuss with the builder.

Thanks. Brad.

You can have to big of an injector. I haven't found to big yet. I run 210lb injectors on my 353ci street car. I can lean it out as low as I want at any rpm.

There would be an optimum injector pressure/duration.

60lb injectors at 0.6 BSFC would deliver 560hp at 70% duty cycle.

You're turning up the Pro Charger...you would be in that 560hp area.

One of your project goals is to streamline and bulletproof the fuel system. Having a buffer on the injectors to ensure there isn't a lean scenario may be job #1.

I wouldn't think you're running at 0.6 BSFC at WOT. Maybe 0.5 or 0.55.

That's at the rated pressure of 43.5psi.

60psi running pressure you may gtg with 60lb inj with sufficient buffer.
