I recall having this discussion with Richard 15yrs ago at Thunderhill Raceway during a USTCC race. I argued that drivetrain losses are *mostly* fixed. But there is also a loss component that is depending on power output. A car that pulls more power to the rollers will generate more heat...

Absolutely. Working on one now :)

I don't think we can be absolutely sure of anything until we finish tuning the 2021. So far all we did was test an incomplete tune file that I spent 30min putting together at Starbucks while chugging a chai latte :)

Greetings, It didn't take us long to start digging into the ECU on our now 2 day old Supra. The same night we picked it up, we read out the ECU calibration and started to work on an ECU tune. The Supra shares the same ECU hardware (Bosch MG1) as some other cars that we are very familiar with...

Good to see you here too. It's great seeing how many current Supra owners are former 86/brz drivers :)

I have some logged data from our 2021 that we dyno tested yesterday. Once I get similar data from a 2020, I'll be happy to post up a comparison between the two.

Car and Driver also used a Dynojet for tested the 2020 and 2021 Supra. But as with all dynos, there is always going to be some variance in calibration. In this case, the Dynojet that C&D used looks to read a bit higher than the Dynojet we used. I think assuming a 15% driveline loss is...

We will be making some announcements soon :)

Yes it was comforting to see a similar delta in both tests. C&D uses a dyno that tends to read a bit high. But the % difference between the 2020 and 2021 is right in line with what we saw. Historically, there have been press cars that have been ahem.. tweaked by the manufacturer to make more...

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...
