Bronco Raptor Hits the Dyno at Livernois Motorsports | Power Numbers Inside!!!
No trip to Detroit would be complete without stopping by @Livernois Motorsports for a visit. Since I had the Bronco Raptor with me, and it was obviously thoroughly broken-in with ~100 miles on it, I thought it would be a good idea to get some dyno numbers on it. Since I had just picked it up it had a tank full of mystery fuel supplied by the dealership. We were obviously dyno ready... Here's how the runs turned out:
After driving back to SC I had a chance to more closely review the dyno charts. Surprisingly, the third pull was the best one. Once I applied the SAE correction factor to it, the final numbers were 315 HP @ 5400 RPM and 362 lb-ft @ 3700RPM. Considering the factors mentioned above and the low 90s temperatures I'd say those numbers are decent. The factory rating is 418HP and 440 lb-ft, and the drivetrain contains far more rotating mass than your average truck.
The torque curve is pretty good, but some tuning could make it better. You can def see that the boost is building slower than what would be optimal. Being able to make the pull in a taller gear would help as well. More on that in the future.
The distinctive amber lights of the BRaptor look great.
She's almost too wide for the rollers on Livernois's AWD dyno. Their other dynos were tied up with other projects this day.
We made these pulls in 4th gear in order to avoid hitting any factory limiters. 4th is 1.76:1, which is not ideal (notice the relatively short sounding pulls in the vid). Had we made the runs in 7th gear (1:1) I would expect the power numbers to be a bit higher. Turbos love load, 7th would likely have allowed them to make more boost and therefore increase torque production.
The numbers are also pretty similar to those from a stock Explorer ST, which also comes equipped with the 3.0L EcoBoost. However, the BRaptor has unique (supposedly larger) turbos. Bigger turbos could also produced the softer torque production on the bottom end that we're seeing. More testing will sort that out.
We have another dyno session planned (along with some power mod installs) in the near future at a couple different shops. I'm interested in seeing what difference a verified tank of South Carolina 93 Octane and several hundred more miles on the clock makes. It'll all be posted here on SVTP. Big thanks to the crew at Livernois for their hospitality.
The metric Dana 50 rear axle stands out with its cast aluminum cover.
The BRaptor's 37-Inch BFGs create an imposing presence, but take a lot of power to turn.
Any guess how much more power we'll squeeze out of the 3.0L EcoBoost in the next few weeks?
