Hello,

For a 450hp engine, assuming 85% duty-cycle and a BSFC of 55 a set of 37 lb/hr or 383 cc/min injectors will be enough. Now, for the same power level and BSFC the app says a minimum of 156 LPH pump would be required.

Cheers!

stock ls3 rails and injectors. If over 600wp than stock zr1 ls9 injectors.
that is the cheapest and best way to go.

Default Correction for 600 HP

Well, adjusting the HP slider up to 600hp the app gives an injector flow of 61 lb/hr (stock ZR1 LS9 are 56 lb/hr) and a pump of 265 LPH. Double check as the pump flow comes below the one suggested by "one fast zo6".

Ls9 injectors are 52.5lb/hr@4bar.

So the stock ls3 rails and injectors will work with the fuel lines and pump set up that the car has in it factory? With a pump upgrade? Motor is looking to be around 520 to 540 at flywheel from estimating

Both will fit. But the manifold opening is 92.
