1000+ HP Supra B58 Finally Hits the Engine Dyno!
Months of planning, hundreds of hours of troubleshooting & thousands of dollars have been spent. Will the B58 live up to expectations?
It’s been a long time coming for this moment, but we are finally here. The Papadakis Racing B58 project finally hit the engine dyno and we couldn’t be more excited to see countless hours of work finally put to test. We have been covering this project since its inception and if you would like to see any of our previous coverage we’ll provide some links below.
Papadakis Racing has been hard at work since the last video. Previously they showed us the team putting together the 1000+ HP engine together for the first time. Considering well over $100k has gone into getting this engine to this stage, a lot is riding on the line. However, considering this is far from Papadakis Racing’s first rodeo with big-power builds, they’ll meet their goals. If they didn’t, they would find a way to make sure they do the next time.
The Superflow engine dyno on which the B58 will be tested is rated from a maximum of 1,500 HP and 1,200 ft/lbs of torque. It is safe to say the Supra engine will fall somewhere below those numbers, but not too far off. The mounting method to the engine dyno is unique and specific to each engine. The novelty of this engine requires some custom work (no surprises there). After 3D printing a reference, then milling and creating a mounting adapter from aluminum, the team was ready to mount. This still needs to connect to a small block Chevy long block bell housing for which another custom piece had been created.
How did they manage to get this complex modern engine to run by itself on the dyno? A standalone ECU does the job. In this case, it’s an AEM Infinity for which they created a custom harness. For fueling, the team is running E85 as a baseline fuel. Making 1000+ HP with regular octane levels is just so much more difficult. After some troubleshooting and fixing a minor leak, the engine was ready to be broken in.
Papadakis started with a conservative 10 psi, then 15 after more troubleshooting. According to him, the engine made “850 horsepower its first day on the dyno.” However, after a couple of technical kinks were sorted, the engine was back for action. At 42 psi, an obvious jump from the conservative figures, the engine was making around 970 WHP, just 30 horsepower shy of their goal. Another kink fixed and boom, 1009 WHP and 908 ft/lbs of torque. Congrats to the team at Papadakis Racing, you guys worked hard and definitely deserved this win.
