Hay im getting the mini dynoed. should i do this with sport on and dsc off and in what gear?

 

will you be driving while the Mini is on the rollers? My guess would be a 5th gear pull to redline with TC off.

I'm curious about others opinions though

 

This may be me being dumb but having no experience with dynos...do the rollers make it possible to make a 5th gear pull without rapeing your clutch? I barely like to set off in second let alone fifth

 

Usually a 4th gear pull is used and you shouldn't be doing it. The shop should be doing the "driving".

 

On a semi-related note, if you haven't seen Garage419, they did a test of two dyno devices, with the Garage 419 Mini. Kind of cool.

Wait wait wait! It dyno'd (on a dyno machine) at 165.5 HP. When MINI says 172 HP (and MINI is known to understate their numbers.)

 

*shrug* Don't ask me, I just thought it'd be an interesting watch

 

LOL

no man u don't start from 5th

u start from first.. and go through the gearbox till u reach 5th

u then hit record and mash the pedal.. from approx 1,500-2,000 RPM till redline..

then u let go and let the engine speed fall... when it reaches near idle speeds u push in the clutch




as for the others asking about the gear

no matter what Car it is.. You always choose the gear that is closest to 1:1 ratio

u don't want the torque multipliying affect of the tranny effecting readings..

 

Ah see I wouldn't have known that.

 

Depends on the dyno used.

 

Dynos are notorious for not giving consistent results from different shops. As long as you use the same dyno each time you do a test, the results will give you the deltas. That wil tell you how well your mods are doing.

 

what is the 1:1 on our care

 

Brake Horse Power (BHP) vs Wheel Horse Power (wHP) at the wheels. MINI publishes engine output at the crank without loss due to transfer (gearbox, water pump, etc). Wheel output is always less. FYI, conversation with Jan at RMW indicated that all the bone-stock R56MCSs he has dyno'd were very consistent at ~164hp at the wheels.

 

5th. 5th gear is 1:0.949

 

my Mini = a Joke

Alta CAI, straight pipe from dp back.

4th gear
sport on
dsc off
dynojet winpep 7
run type: RO, 79 f, 30.00 in-HG, humidity 27%, SAE0.97

 

Sounds about right to me, but then again there are a lot of differences in the dynos too. Just do some mods and take it back to the same place and check the delta's.
