Hi Guys,
So, after reading some posts earlier today discussing gear shifting and torque curves I decided I wanted to know the torque curve (and power) of my '96 model 80 series, petrol. I jumped onto Google and have now been fustrated for about an hour and 1/2 bottle of red less. I haven't found a thing!!
If anyone knows of a site or just the facts i'm after I'll be able to enjoy the other 1/2.

Cheers,
Alex

Hi Dave and Alex,

I think you will find this graph is NOT at the rear wheels. The graph I put up earlier is at the rear wheels of my GU. You will lose something like 30-40% of this in your drive train. So the peak power figure would be closer to 110-120KW at the rear wheels of this car (approx obviously). similar loss in torque as well.
I don't know why there is not one standard graph comparing "car A" to "car B" for all makes. It drives me crazy.

Trevor.

Hi Alex
Have some info that may of use
4.5litre 1fz te 6 cyl
power 165 KW @ 4600 rpm
torque 387 NM @ 3600 rpm
These figures are for 100 series cruiser but I think you will find that they are applicable for 80 series as well
as comparison
4.7 litre 2uz fe V8
power 170 KW @ 4800 rpm
torque 410 NM @ 3400 rpm
If you are overtaking/accelerating you should be working towards peak power
If you are towing up hill you shuold be working towards peak torque,

Alex
3200 rpm is max torque, so also max motor efficiency...problem is, this is usually way too high revs for a 4.5, as they have a flat torque curve, that has over 300nm at 1500 rpm.......so i missed the discussion b4 about changing gears, have heard all sorts of driving in a 4.5 will return thesame fuel economy because the motor is always driven outside of its maximum efficiency revs, but if you drive it there, it uses thesame anyway...having owned a auto 4.5, it used to go best in power mode, when the box would hold onto gears longer,. and change down straight into 3200rpm (350nm) in the next gear...
