That's mine, its a Hilborn Injector with telescoping stacks controlled by a electronic linear actuator. We did this for Engine Masters Challenge in 2017, ran out of time testing with only 20 pulls or so, and ended up Runner Up against Kaase MEL while snagging Best Appearing Engine. Learned alot about variable runner length and I still have it sitting in my shop today!
