Sure, a 550 CAN do 500RWHP, but it's at a higher duty cycle than most injector manufacturers will guarantee (most people you talk to will recommend 650's for 500RWHP). Flow ratings are peak, not the max sustainable flow. EDIT: Oh, and if you're running so rich you're shooting fireballs, I'd completely forget the fuel filter and expect to spend time troubleshooting the knock sensors and ignition system. __________________ If something breaks or you need to contact a member of the administration please post HERE.
