Huh? Can calculate in this way meh?

wana sell to me?

I thought vehicle's curb weight is often specified in the car brochures (Heck, you can even find it in Wikipedia)?

Empty your boot and just add driver's weight to it can?

I got the software. Its completely useless.

Sure,I have no use for it!

Shoot me a pm!

If have wider tyres will be different again.....

Different countries have different accessories. In Europe Aircon is optional so it would be lighter than Malaysia version.

So, actual dyno will still be the most accurate.....

If you have your engine rpm & speed logged, together with car + driver weight, & aerodynamic drag you can calculate relatively accurate data, not sure how often the dynos are calibrated.

Just a sidenote for dynos where do they plug in the engine to read the rpm?

To me, benchmarking solely on hp alone is pure crap. In the real world, Power to weight ratio, 0-100 or quarter mile time are the benchmark. Whats the use having a 300 hp with a 2.5 tonne weight, when a sub 1tonne car with half the HP can easily out maneuver and perform better than the big hp car? Not to mention, a low HP car with a high torque makes urban driving much more fun.

also depends on the dyno. so far innertia based ones are most accurate. like dyno dynamics.

Very true......

Anybody know how to get dyno? Can share with me please =)

go to sunway and ask around "where got dyno?" and u'll find it...............

The problem now is I am living at Sabah now.

Somehow a bit of a problem there. I have some members from Labuan, Kuching also, and some mention have to travel further to source for service or parts also....

Because there is no much highways for us to speed. Our highways just have two lines only plus our roads are too good already until I don't know how to say. 3months need to alignment a times.

Understand, as I was in KK a few years back for an assignment, but for a few days only.
As far as I know the sales personnel who took me around, mentioned the road to Sandakan very winding so good to play but dangerous......

Ya... Tat's y most of the people here r driving 4X4 cars... Small car nid to alignment everything especially sportcars..

Actually that's how inertia dyno like Dynojet works. Instead of car+driver weight, it uses the roller's fixed weight.

I've done this to my Exora Bold CFE. Using home-made Excel. Something like this :



The formulas are explained here : http://www.herberts.org/wayne/valk/valktorque.htm

I added aerodynamic drag & rolling resistance formulas for final values. Looks pretty accurate to me.
