Power test results S60 2001

posted by  someone claiming to be Dutchman on  Wed Dec 11 05:53 CST 2002 [RELATED]

Just to inform you.

A few days agoI had the car tested. Reason was that I had slight detonation under non-normal conditions last summer. It turned out to be the spark plugs. After changing the plugs it was practically free of detonation (EU RON 95). To be sure the dealership decided for a power test from which it turned out that everything is okay now.

The results are as follows (from the graph):

- Specification: 102.5 kW (=139.3 HP)
- Measured: 104 KW @5170 rpm
- Measured at wheels: 82 KW
- Power loss: 22 kW

Conditions:
RON 95 fuel
Air temperature 30 deg C
Oil temperature 80 deg C.

Notes made by the specialists:
- short detonation could only be enforced at full throttle from 1000 rpm in 3rd gear. This is outside the bandwidth of the correction loop with the detonation sensors (retardation of ignition, etc)and therefore not corrected (immediately).

What is also interesting to notice is that maximum power is reached at 5170 rpm. This is in agreement with the - limited- topspeed of 209 km/h on the radio display (223 km/h tacho)which I reached on the Autobahn.
However, the Volvo brochure reads that maximum power (140 HP) is reached at 4500 rpm. So, the latter is not the case.

Greetings,

Dutchman
