    was just wondering if $285 shipped for a set of rc 550s was a good price? and that size injector would be topping out at about 400-450 hp correct? thanks for any help ahead of time

    The price isn't bad if they are new but why not just put DSM's in with a resistor box for half that price...

    Use the conversion table here to figure out what size injector you need:

    "edit: They are high impedence right? "

    Injector size in lbs/Hr = Expected HP x BSFC / # of injectors

    use .55 for BSFC(BrakeSpecificFuelConsumption)

    To convert Inj.'s to CC's=[(Inj size in lb/Hrx454)/60]/.75

    that equation was a little better. like i said, with the website one, i plugged everything in and it came out as needing 721 injectors. :blink: In hellbents equation, for 400 hp, injector size came out to 554.88, so some 550s should do me just right. :D but rc 550s new for $285, good deal, or does anyone here know a cheaper place to get em?

    thats funny. you're prob looking at the same 550's on ebay that i am, there's 2 'Buy It Now's. i think that's about the best price anywhere for one of the better aftermarket brand injectors.
    you buy 1 and ill buy the other.. :D
