Many car fans suspected that Toyota underrated Supra’s maximum power. But it took time for the truth to come out once aftermarket companies started to put the vehicle on the dyno. Latest to join the list is UK based Litchfield Motors that has some big plans for BMW sourced B58 motor. Before attempting to tune the turbocharged 3.0-liter straight-six engine, Litchfield Motors wanted to find out how much power and torque it delivered in stock form. Officially number of 2020 Toyota Supra is said to be 335hp and 500 Nm of torque.
Dyno (which is German made MAHA unit used by BMW too) gave a different figure that stated to deliver 376hp and 529 Nm of torque. The figure is quite close to US-spec BMW Z4 M40i that goes on to prove that Supra has the mechanical muscle as its platform sibling. Nonetheless, Litchfield Motors had an option to push the B58 engine to over 400 horsepower with a simple software upgrade. UK based aftermarket tuner has already produced test arts ad said that it can already program ECU by OBD port with help from BFlash.
This revamp makes the output jump to 420hp and 597Nm of torque. What is more interesting is the fact that hardware was untouched and Litchfield claims that it can squeeze more from B58 engine with help from Milltek and Akrapovic exhaust setups. Company has its own plan to produce their lowering spring kit for the 2020 Toyota Supra along with suspension bush replacements that is set to improve grip and steering feel. Litchfield is considering carbon exterior upgrades for 2020 Toyota Supra.
