Was there a factory defect involved?
What we have here could be the world's first blown A90 Supra, which was being built by German tuning outfit Dreihundert. Details are scarce at the moment but the tuner, via Instagram, has promised more updates will come in the following days.
What we do know is that they've already removed the Supra's engine and a full teardown is currently underway. It appears the tuner was working on power increase modifications when it was discovered the engine had a manufacturing defect. Unfortunately, it was too late to save the engine. According to the Instagram post, the engine potentially has a "manufacturing issue, they dropped the piston & rod in the factory. We touched the fuel limit around 650 whp, added some meth and pushed another 4psi boost."
A stock 2020 Toyota Supra, to compare, has a total of 335 hp and 365 lb-ft of torque, with power being routed to the rear wheels through an 8-speed automatic gearbox. So, how did this engine essentially get killed? Well, the Supra's fuel system was running on 27 psi at the time, though it was supposedly maxed out at 24 psi. That probably had something to do with it. This was either a mistake on the tuner's part or the stock engine itself couldn't handle the extra power.
During our own conversations with Toyota officials regarding Supra aftermarket modifications, they've expressed nothing but support for the tuning community. They knew well in advance the Supra would become a tuning favorite - within the confines of the engine's capabilities.
We even asked Supra chief engineer Tatsuya Tada last year about possibly increasing the coupe's output but he didn't feel this was necessary for Toyota to handle. The aftermarket industry would take care of that.
Hopefully, we'll have more details and photos in the coming days about this now ruined Supra engine. Could this particular Supra's manufacturing issue be found in other examples? Is this type of thing under warranty? We've reached out to Toyota for comment.
