I have a serious turbo problem:

We installed a 3SGTE engine in our MR1 endurance off road race car (3 hour race with deteriorating terrain think motocross, very popular in belgium)

The engine features a Mitsu Lancer Evo III turbo, and spools up at around 1800rpm. we ride at 400gr turbopressure 205 hp and 260Nm torque.

We also ride with a oil cooler system.


After a few hours of racing (7-8 hours) the engine starts dropping power...
