dyno run'd my micra

[mik]

I drove my micra yesterday on the dyno.
Came out some nice 85.7HP and 115nm

I'm pretty happy with it, as its not much modifications done performance wise.

mods:
catback exhaust system
ga16de injectors
k&n panel filter
modified air pipe

So thats 63 at the engine and only 45 at the wheels yeah?

 

[CMF_sikK11]

And i see it was done in 3rd gear. This will give you a higher power figure also as its not 1:1 ratio. Most manuals are done in 4th for that reason.

 

[CMF_sikK11]

Also your PS is slightly higher then BHP.

See here
Actually an SAE hp is slightly bigger than a DIN PS.

You get 1.0139 PS per hp.

DIN is German and SAE is the US standard.

The ISO measure of Power is the kW and there are 1.36 PS per kW.

Here endeth the lesson. Amen.

uhm, good question. i'm new to that dyno run stuff and all those terms :-/
the 3rd gear is 1:1, that's what they said.
there' also a gear correction factor on the sheet which says:

gear: 1.03 correction factor
din: 1.02 correction factor

anyone maybe an answer?
18kw loss is huge in my opinion.

 

[CMF_sikK11]

Yeah 18kw is a massive loss in a FWD platform car. The micra came out with 55kw to start with i think so the power is about right though the figures in my opinion dont match up. My dyno run the other day on our Supercharged Micra on 6psi is 86kw at the wheels.

 

[CMF_sikK11]

Oh and that was in fourth gear also.

Between 13-16kW is the usual range for the K11 gearbox dependant on condition.
