Turbocharged engines can make plenty of power. Keeping that performance as temperatures rise is the harder part.
On a four cylinder turbo engine, high intake temperatures can cause the ECU to start trimming power. That becomes increasingly relevant when the car is being driven hard or repeatedly.
On this MINI JCW GP, I’m using an upgraded front mount intercooler, intake changes and engine recalibration to improve cooling and intake efficiency.
The objective isn’t simply a bigger peak figure. It’s to make more power while keeping temperatures under control so the performance can be maintained for longer.
For a road or track car, repeatable performance matters more than one good number.
