Does anyone publish a horsepower number for F-150 upgraded turbos?
Often, yes. Of 26 F-150 upgraded turbos in our catalog, 19 publish a horsepower figure and 7 do not. Every figure below is labeled with where it came from: an independent test, the manufacturer's own claim, or an estimate from comparable hardware.
the ones that do
why the rest don't
CLAIMED (capability ceiling, not a bolt-on gain) - Full-Race states these Garrett PowerMax Stage 2 turbos can support upwards of 700+ whp once properly equipped / with supporting modifications (verified 2026-07-26). This is a supported-power rating that assumes fuel, tuning and supporting mods, NOT a measured gain over stock. No torque figure is published. Source: https://www.full-race.com/garrett-2017-2020-ford-f-150-3-5l-ecoboost-powermaxtm-stage2-turbo-upgrade.
Same Stage 2 basis as above: "54% more flow, 400-700+ whp with supporting mods."
No whole-truck HP figure published for this specific application - this is a race-oriented big-turbo upgrade requiring custom fabrication and professional tuning, sold as reverse-rotation individual turbos, not a complete matched kit.
No manufacturer-published HP figure found. Forum/retailer chatter exists but is not a confirmed dyno claim - not entered as a real number.
