Dyno Results Of My 2Is - Good Or Bad ?

[turmoll]

Hello,

I put my 2IS on the dyno. These are the results:

my 2IS:

Power: 197,5 HP(M) @ 6310 rpm

Torque: 246Nm @ 3766 rpm

Milage 106 000 km

Temperature 28 C

series (expected):

Power: 207 HP(M) @ 6400 rpm

Torque 250 Nm @ 4800 rpm

Seems I lost 10 HP(M).

We do not have much 2IS in Polish forum to compare results so I want your opinion.,

Thx,

turmoll

What is it supposed to be/were you expecting?

I want to find out if it's common that this V6 is under powered or I should start tracking some issues.

10hp isnt that much of a varience. Could has been the rollers. Car may be due a service. Climate control may have been on. Not high enough Ron fuel used. If it was 15hp or upwards id be looking for issues. If you get all the above done and do on a cool day it may get closer to stock figures.

Previously I owned Vectra C Z19DTH 150 HP (M). I put it on two different rollers (including the one I was with 2IS) and I got 153 and 154 HP(M) . So I assume this roller is pretty reliable.

Climate control was off.

Car was at 104 k km in the service, however it was not 'full-service' but 'half/in-beetween full service' and air filter was not changed.

Fuel was ordinary 95 Unleaded.

I think I will try in cooler day, with 98 petrol and/or Shell V-Power Nitro+ after air filter changed on the same dyno.
