Greetings, Here is a graph comparing a 2020 Supra to our 1 day old 2021 Supra. Both 100% stock. Both on the same dyno running California 91oct premium fuel. the difference in power output above 5000rpm is profound where the 2021 car enjoys a 40-50 wheel HP advantage. Full disclosure: This is the only 2021 we have run on our dyno. So I don't like to make assumptions based upon a sample pool of one. It's more than likely that it is representative of all other 2021 cars but until I get more samples, I can only assume this. The 2020 car is in line with the other 2020 cars we have tested on this same dyno. That said, Toyota's hp increase claims of 47hp between the 2020 and 2021 seems right on the money. Although the power rating for both the 2020 and 2021 seem to be conservative (ie, car makes power power than claimed). It's really impressive that they decided to make such a big power bump after the first production year.
