No, not common rail. It's a true blue 7.3L Powerstroke with compound turbos making over 100psi of boost along with a crapload of nitrous.
I've been around the block in that truck with smaller injectors than these...it's freaking insane! What's truly amazing, driving it around town in a "normal" manner, you'd never know there was any serious HP parts if it wasn't for the WOP stickers, NOS stickers, flames.
