Putting the TESTAROSSA on the DYNO! How much HP will it make?!

The Project Ferrari Testarossa is almost ready for it’s major, but before we take the engine out of the car, we wanted to see what it will put down on the dyno. The factory rating is 385HP at the crank, so you factor in a 15-18% loss and it should put down somewhere between 315-330HP if it is in perfect condition.
