injector size and brand for S/C'd nitrous ranger

[V8RangerBoy]

You'll be fine at 9.4:1 on mild boost, like everyone else has said. A cheap and quick way to gain a little lower cr is to throw on a set of thicker head gaskets. The only bad thing with a PD blower is they build a pretty serious amount of heat compared to centri's and turbos, but they build alot of power in a hurry! A good tune and 93oct gas and you'll be good.
