Since the RC550 injectors was sold off with the Hydra I got myself a set of the all hyped up Injector Dynamics 1000cc from 949Racing. They are said to have excellent idle characteristics and can handle variations in fuelpressure without big alterations i spray pattern. OEM connectors and handles E85 if that should be necessary. 1000cc is probably way more then what I need but didn't cost any more than the 800cc ones. Nice and shiny anodized covers that will add 500+ hp with the included stickers! 600-700cc shold be enough fuel for 400whp so the DC will probably in the 70-80% range.
