Original power

[CMF_swiss n/a]

Hey peoplez
well im new here, and iwanted to ask, if some of you dynoed the car, when it was stock? well i did and had about 62kw at wheels...

Are you certain of that?

62kw at the wheels sounds very optimistic. Mabye the dyno was giving an approximation of flywheel kw?

62 is a bit more than the factory 55kw but I wouldn't be suprised if nissan was a little conservative with how much power the cg13 makes.

 

[CMF_jamm'n]

i'm pretty sure 55kw (stock) is off an engine dyno, as opposed to chassis, which is what we normally use here to give ideas of power increase after mods and such:-D

62kw on a "chassis" dyno is not correct for a stock micra.

 

[CMF_jamm'n]

what does...'had "about" 62kw' mean?

 

[CMF_swiss n/a]

well it still has 84.2 PS and 118.1 Nm
and there was only an kn changefilter installed.
the airtemp. was 36°C.
i will scan the results and put it online...

 

[CMF_swiss n/a]

yeah and it was a chassis dyno where the car was spinning a drum...

 

[CMF_Polar]

i have known of another micra to get that much at the wheels also with K&N and back section exhaust only. so could be within the margins of what a rolling road would calculate.

 

[CMF_swiss n/a]

and now for those, who wont believe me... =)

 

[CMF_Yom]

Its not that we don't believe you.

The way Dyno's display and calculate power differs very slightly between every dyno and especially around the world.

It would be helpful if you could find out what power reading is recorded on that print out.

Whether it is power at the wheels or a calculated flywheel figure.

Also - does your engine number match up with the number on your build/compliance plate? If you havent owned your car since it was brand new, it is possible it is sporting a non-standard motor.

Cheers

well in the service booklet stands nothing, that they swaped the engine! but i didnt looked on my own, if the number is the same! most of my mates had the power they should have to! my car was the only 1 who has that difference...

but im gonna check that out..

greetz from the sunny switzerland... =) (yiippiiieee, the summer is coming...)

 

[CMF_jamm'n]

off topic. how offen does it get that hot in switzerland >36'C?

 

[CMF_Polar]

maximum average mid summer is 25. so 36? i dont know, unless it was in a sauna, or in direct sunlight...

 

[CMF_swiss n/a]

well, it was on a hot sunny afternoon... but dont ask me, why the air intake temp. was so hot...
and my mates yaris turbo was over 40°C

[CMF_Alex_B]

ambient air temp is different to air intake temp, lol.

it would be an @ flywheel figure. seems there is always a huff about figures on here, i think its safe to assume all/most euro dynos are giving out flywheel figures whereas all/most ausralian dynos give out power at the wheels. if you allow 15-20% for transmission loss it works out that you have abit more power than factory. Just not possible for the little cg to be putting out such powah without bigger intake/extractors/morefuel/light flywheel

interesting that your peak torque is very early compared too stock at 4000rpm, wonder is that due to the catback exhaust.

[CMF_Yom]

Well alex that could just be the case. We can't tell if they've got a non-standard motor, mabye even something like the fabeled JDM alpha spec.

 

[CMF_Alex_B]

my bad polar mentioned catback exh, you only have k&n panel filter,

Alex

 

[CMF_Polar]

the figure i gave was at the wheels, 83bhp with K&N and cat back. UK dyno mostly give fly and @wheels figures.
