today at the AMD Essex meet i thought what the heck, ill put the Citigo on.

 

Here is the result, you can see the dip at 4400 revs where on the 60PS engine the power starts to drop off a little, compared to the 75PS where the power keeps climbing.

 

So of the two runs it achieved an average of 82.7bhp and 84.3 ib/ft. The rollers were recently calibrated for some touring car stuff.

 

 

 

That's good. Nice to do something different on the rollers

Interesting. I wonder why the official figures seem so understated in comparison to these results.

im currently trying to work that out myself, the general consensus is that grippy tyres add more "transmission loss" so does that mean skiny low resistance tyres like on the citigo could cause it to over read?

Not sure. That depends on calibration, and how we interpret the numbers. As a physicist, I'm naively taking these figures to mean that the dynamometer was dissipating energy at a rate of at least 82.7 hp (allowing for losses in the test gear itself). If that's the case, and since the CitiGo's engine is the only thing putting energy into the drivetrain--dyno system, I would consider that figure to be a pretty good measurement of the lower bound of what the engine was achieving at peak output.

 

Of course, a dyno expert might come along and correct me...

 

(One also has to wonder what the "official" power and torque numbers actually mean. They never quote them with a standard error.)

there is a correcting factor of 0.92, so I assume that means they are assuming an 8% power  in the gearbox and tyres

 

but the figures are 10% over stock figure, so which ever way you look at it the figures seem to suggest the 75bhp figure is conservative, depending on the calibration accuracy of the rolling road

I believe the correction ratio was for the temperature and other ambient conditions.

I'm guessing with the drop-off dip for the 60ps engine you could roughly fill in the curve it seems to suggest.

I was impressed with your figure, and your flapping bonnet

 

Next time I will bring the citigo as the Octavia cannot be RR'd :(

thanks

 

 

I thought it was funny that the guy running the dyno didnt know which engine CC it was nor where the bonnet stay was XD

Don't tell the insurance company !!!

I dont see what it has to do with the insurance comapny? there was no accident or damage occured, even if there was i know i would not be able to claim though my car insurance.

 

just like taking your car on a track session, normal car insurance will not cover it, if you bin it, you pay unless you have taken out separate car insurance 

Impressive figure.

 

VAG engines always seem to get more than they quote.

Why can't it?

I think Owens was being tongue in cheek meaning that a standard Citigo Elegance Greentech is rated at 75PS but the rolling road figure achieved is nearly 83BHP!  I think he was meaning that your insurance company would think that your car was tuned, having all that extra power.  He was only joking of course but I'm sure when he reads this he'll either agree with me or tell me to mind my own business.

 

You're a very, very lucky man Taylor93 because you drive a veritable Rocket Ship!!  Your car is rated at nearly 9PS more than a normal Citigo Elegance Greentech 75PS and your power figure is at the wheels too, not at the flywheel.  I'm green with envy!!

haha thanks!

Software issue. More common on Audi's (so the guy said). If the rear wheels are not rolling the car cuts power to the engine. The graph was "all over the place" so they could not get a result. He said he's only seen a few skoda's with this, normally they are 2010 models but mine is a 2009.

 

Trust mine to be different.

 

Next time I will bring the 60bhp Citigo.

I know it sounds obvious but did they try with the ESP/ASR turned off?

I'd like to think that they did try that, maybe its the early version of the XDS system?

Phew!!   I've had sleepless nights thinking I shouldn't have poked my nose in.   Thanks Owens.

European & other World Region Car Manufacturers showing official figures like 75 PS,  are showing Minimum Figures.  

 

So that is the power output that is a minimum all around the world at different Altitudes, Air Density & Climates

I would always expect higher than minimum in the UK, @ UK type temperatures and humidity,

near to Sea Level or at least below 4,000 feet above sea level on UK fuel of a minimum 95 ron.

(maybe more on minimum 99 ron with many modern vehicles)

 

If a car with a minimum 75 ps only puts out 75 ps in the UK or Mainland Europe, its not likely to make that in other some others countries or Areas of the World with different fuel & climates.
