Adam LZ wants to get his Toyota Supra in the quarter mile to nine seconds, but his car doesn't cooperate. A new video documents a recent attempt and there are a lot of setbacks along the way.
First it turns out that there is a problem with the superstructure for the nitrous oxide system of the Supra. Nothing of the substance is injected when the vehicle starts. Adam needs several runs before he realizes this.
Then the first real problem arises. If the NOS is working properly, the Supra breaks its rear axle shafts immediately when moving off. Adam is very lucky and the new reinforced components from Driveshaft Shop are available on the route. While the stock components are hollow, they are solid, which means that they can withstand the powertrain punishment.
"Should", however, is the key word in the previous sentence. With the new axle shafts it is time to drive the Supra again. However, the car breaks off. From there Adam simply takes the car home.
A follow-up video offers a deeper insight into the problem. The culprit seems to be the differential. But it still hardly works. The stronger axle shafts apparently stand up to the punishment of the powertrain, and the differential is now the weakness of the powertrain.
The Supra uses a 3.0-liter inline six-cylinder turbo engine of the type BMW B58. The analysis shows that the closed block design of the engine and the strong internals should make it possible to withstand 1,000 horsepower (746 kilowatts). According to the video by Adam LZ the drive components behind the engine are the problem when it comes to increasing the performance of Toyota's new sports coupe.
