175.16 lb-ft
With stock FRS at 173whp (SAE) on the same dyno, the GR86 is making over 48whp peak, and over 55whp more at 7,000RPM than 1st gen.
"The FA24’s power curve is very similar to the FA20 with a CARB-legal supercharger."
"With the 2022 GR86, Toyota claims 228 horsepower at the flywheel. Toyota lied. We measured 221.25 horsepower at the wheels. That equates to 260 horsepower at the flywheel. Toyota has underrated the power by nearly 15 percent. In comparison to the first-generations FA20 engine, the 94mm bore FA24 engine delivers 28 percent more power and 21 percent more torque from the 19.5-percent larger displacement engine."

I agree about the difference, and THAT is the important thing here - I don't want to stress that enough, the car is far more powerful stock than just 25hp over the last gen. However the flywheel prediction is not worth much. SAE is one thing, but with all the other set-up and configuration on a roller dynos mean that trying to say what the flywheel power should be taken with a large grain of salt.
