I'm booked in for a power run tomorrow on my standard vRS. Just to see how it behaves on the rollers and where the power/torque currently is. They use a dyno dynamics rolling road. I know figures are considered "pub talk" but i would like to see what it is producing as standard.

how accurate are these dynos? and does it depend on the operator?

Hi mate, no harm in checking if your curious! it depends alot on the rollers as some vary quite alot , ive been on a couple of different sets in my previous car and recieved quite different results, also it gives you the chance to see 'whats what' [if you know what i mean] and in the end aslong as your happy with the results and the way it drives then its all good fun!!

cheers mark

ive been on a few RR days with different cars and its always good to see how they are i ran my Vectra Gsi 2.5 V6 on them it had a an LPG conversion so did 2 runs one on V-Power petrol 180bhp i beleave it was then on LPG 178 bhp very little difference which was nice to see should have checked my fabia before the remap but only did it after it had 178bhp 285 ft-lb but at the end of the day its pub talk but at least you can see how the car is health wise enjoy mate

Hi

Mine pulled 148bhp with a filter and Ibiza intake but standard map at P torque before a remap and I've heard it's the norm for them to have more than 130bhp.

Regards Chris

No harm in getting it tested!

At least you have something ti talk about in the pub now!

Got mine done last year, was/is standard - 152 bhp and 255 lb/ft

Hi,

just got back from the rolling road!

results are taken from a dyno dynamics RR

141.8bhp and 260lb/ft torque at 2400rpm

That is more than I expected on the torque figure. I will try to post a graph.

Am i right to think that although the torque is 260lb i'm unlikely to actually "use that" or achieve it unless i'm really flooring it?

Just don't floor it at 2400rpm

I test drove a Fabia VRS yesterday and it felt fast, evan compare to my Cupra TFSI, i told the guy that it had been remapped (sure did feel like it) but he was addiment that it wasn't, black smoke was coming out the back when i floored it, and felt so torquey, are these little fabias really that quick standard?

lol

BHP sells cars, Torque wins races

They 'feel' faster than they are, but give them enough stick they can embarrass enough cars!

That's very similar to what I got last year.

142.1 BHP @ 3,910 (113.2 at wheels)

248.2 lbft @ 2,109 rpm

Mine is a bog standard 2004 vRS. What year is yours?

Always ask to see the calibration certificate if you want to trust the output figures . If the rolling road is not calibrated then the figures cannot be relied on.

sorry to sound dumb but whats the difference between hp to the wheels and fly wheel power?

I got 115.7hp at the wheels and 750lb tractive effort.

The wheel power is what it measures on the power run (when accelerating), the computer then calculates the flywheel power from the transmission losses when coasting to a Holt in neutral, (James May mentioned it on TG once) it also takes air temp and pressure into account. I have no Idea what tractive effort is.

Thanks Jim

Mine was running before the map 140bhp with 267ft/lb!
