Your point is valid IF hp was unchanged. With 430 hp, the torque at every given rpm will be higher compared to the 2020 model.
I wouldn’t be at all surprised to see the torque of the 2021 model at 1800 rpm at 1000 lbft the same as the 2020 model was. Often the torque curves follow a pretty straight line from peak torque rpm to peak hp rpm. So if the peak hp of 430 is still at 2800 rpm it will produce about 807 lbft of torque at 2800. On average the engine is gaining 18.6 lbft of torque per every 100 rpm that it drops from 2800. In other words it would seem reasonable to expect a torque rise of about 150 lbft (8 x 18.6) or about 957 lbft at 1800 rpm. So I’d be surprised to see it much higher than the 2020 model. This is what I’m really getting at is that I think this 2021 torque rating is more of a thing to gain boasting rights than to actually bring a more powerful engine into the game.
