When the new M3/M4 was released in late 2020, it didn’t take long to see them hit the track. CSF’s Engineers and Motorsports department was in attendance for some of the first track days that local R&D Partners & Premier Dealers Studio RSR and Art of Attack took their new G8Xs to. The results were not all that surprising. Similar to the 2nd Gen B58 cars (A90 Supra & BWM G2X), the S58 had major issues with heat soak. This overheating of the intercooling system causes a large spike in Intake Air Temperatures (IATs). Subsequently, the ECU started pulling timing which decreases power output. In extreme cases this can also send the car into limp mode. This problem became even more prevalent as testing continued into the hot summer months.

As with most performance vehicles, power adders were some of the first product to be release for the new G8X platform. Bolt-on upgrades, software tunes, and upgraded turbos are all great for speed, but most of these only exacerbate the heat issues the car already has. Any time you add power to your car, you naturally increase the amount of heat the engine produces.
