Are Waste gates Worth It or Just Wasted Time?

Will and Myer hit the Dyno with one goal in mind. Find out if external wastegates actually help make more power on a compound turbo setup or if they’re just adding extra complexity for nothing. After 43 pulls on Will’s 6.7L Cummins race truck, they’ve got some answers and a few surprises.They tested screamer pipes and hot pipe gates, played with turbine housing sizes, swapped cams and valve train parts, and tried different control strategies to get this setup to break past 1800 horsepower on fuel only. Some combos picked up power. Some didn’t. And a few just made things harder to tune.In this episode you’ll hear- How screamer pipes compared to hot pipe gates in real-world Dyno testing- What boost and drive pressure numbers actually meant for power- Why a 900 horsepower street truck might benefit more from gating than a full race build- How housing changes made the gating more or less effectiveWhat the data told us about controlling the manifold charger without snuffing itWill also shares his theory on why this truck might be capped just short of 2000 horsepower and what it’s going to take to push past it.Myer brings in insight from testing smaller builds like the Junker and the VP Dually and how they responded to different wastegate setups.If you’re building a high horsepower truck or just trying to get your setup dialed in, this one’s worth a listenSubscribe to the Power Driven Diesel YouTube channel for more Dyno testing and real-world tuningShop the parts we used at www.powerdrivendiesel.comDrop a comment if you want more live streams or have questions for Will and MyerShop the parts we used at www.powerdrivendiesel.comDrop a comment if you want more live streams or have questions for Will and Myer
