Default 450cc inj max?

Off the top of your heads, does anyone know how moch power you can put down before maxing them out? I currently have dsm450cc peak and holds, phaseII block and heads. They are fine right now(8psi w/ 10:1 comp.) But I am building a new shortblock with Sti internals. Anyone have experience?

450cc will get you safe to approx. 320/330 bhp. That is if your fuelpressure is right.... If you use a wideband you will see until wenn your afr is good enough.
