drivetrain losses?
 

Yesterday I got my car dynoed. It seems results are quite ridiculous. Since I've a stock MY98 Impreza Turbo and the engine power should be around 218hp, the dyno sheet shows +25 hp(243hp). In addition to this, it shows 85hp power losses. Is it possible to lose 85 hp on wheels since its a AWD car. I've no problems with drivetrain.

Here is the dyno sheet:

Lets clear out this...

Engine Power: 178.6 KW@5906RPM (242.7 HP)
Wheel Horsepower: 115.8 KW (157.4 HP)
Power Losses: 62.3 KW (85.3 HP)
Real Power: 216.4 KW (294.1 HP) [DIN70020 rule] ===> I really dont know what this value shows?

Max Torque:325.3 NM 4016 g/m (151.4 km/h)
Transmission Ratio: 1.0:1
Final Reduction: 2.9 [dyno detects automatically. (fifth gear ratio) 0.738 X 3,9(final reduction) =2,8782 )]

Here is the manufacturer specs of my car:

218 HP (160 kW) at 5600 rpm
290 Nm at 4000 rpm

All datas are here in DIN europe standard. Measure at 101.3kPa and 20°C. Rated in hp (ps). 1kW = 1.360hp (DIN). So I don't know how do I gain +25hp on my car. Drivetrain loses seems too much, isn't it? I dont know if I should trust this dyno. Any input would be appreciated.

ps: I've a catted Blitz Nür spec R muffler(not catback or turboback) and walbro fuel pump. I dont think so that they had affected the performance of my car.

does AWD eats power? any input?

Dependant on type and make transmission you will loose that sort of amount on most 4wd be it scoobie lancia ford mitsi etc
