Had my standard Fabia vRS RR'd yesterday. It come back with 143.4bhp and 291lbs/ft, yes you heard right, 291!!! :eek:

I've posted this on another thread, but do not want that thread diverting from the topic.

What does everybody think of the results?

Yeah would help to attach them.... :P

If it's a 53-plate, it presumably has the long-legged gearbox. How many miles has it done?

And what's the dip at 2700 rpm?

Got to admit they look a bit strange particularly that big dip around 2.7k....

I believe the torque plot is the bottom of the 2...and it doesn't look very smooth although I guess the overall shape is inline with what is to be expected from a diesel...high at lowe revs with a gradual tail off with higher revs.

It is a 53 plate with the long gearbox and has covered nearly 22k. Anyone know what could cause that dip, the guys at RR seemed to be pretty happy. Do you think it could actually be the car or their testing equipment?

Me too, also the dyno must of been out as 291 lb/ft is not attainable IMO when the car is stock, dont think the RR will of been able to handle the power...

Looking at the mph and rpm together, it must have been fourth. Could the dip of been the car trying to jump off the rollers? :eek:

They use a SUN Dynamometer, which is supposed to be one of the best in the country, they also had a 500bhp 200sx on after me...

Could the power dip (on the graph) be due to wheelspin/slip on the rollers?

If the operator forgot to turn off the traction control, might you get that sort of dip?

It is a funny place to slip, if it was going to slip IMO I thought it be around 1,800-2,000rpm?

Have they experience of VAG diesels? The graph would suggested the rollers were incorrectly weighted.

He disregarded the first run as the traction control cut in, but it was definately off on the 2nd run!

No, power would be almost completely cut as the ECU would think the front wheels were spinning out of control due to the rears not moving at all.

I know that they are a very experienced company, with people in the know, however I don't know about there experience with VAG diesels. If the rollers were incorrectly weighted, what actually causes the dip in the graph, the car pulling off the rollers and falling back on??? :confused:

If incorrectly weighted then the dip would be explained by the boost backing off due to the ECU seeing insufficient load. This would also explain the generous torque figure as the car would be finding it too easy to turn the rollers. If the tuner is more experienced with older highpowered turbo charged petrols with simpler ECU's then this could explain it. Well Lane Turbo Centre in Batley fall into this category. They are very exerienced with Cosworths, Scooby's and EVO's but get very strange figures when running newer VAG cars.

That dip sure looks odd though :|

At 4138rpm in 4th you would be doing about 110mph in a 53 reg car not the 98mph it states. You wouldnt be doing 98pmh in 3rd either you would be doing about 85mph. Somethings not right somewhere!

It's definately the older gearbox, I've driven both! I've just taken my car for a spin up and down my road, I am doing 50mph at 2,000rpm in fourth, speedo lies so call it 47mph. 23.5mph per 1,000rpm, so if my really big calculator is right........................97.2mph at 4,138rpm, thats close enough!

So do you think this would be a more accruate dyno? (green line)

No, still too high, this is more like what to expect:

So the graph I have is as good as useless then really... :thumbdwn: Do you think I should get my money back on the Power run then, cost me

The newer ones are a little up on the factory figures, and they have the gearing tailored towards being able to use 6th to still accelerate with (that said, you need 5th or 4th if you really wanna take off )

The newer ones :eek: I didn't think there was any difference between engines! I thought it was only the gearbox that changed! :confused: I've driven both and I must say I prefer the much lower reving of the earlier model. I used to have a 106 rallye that reved at over 4,000rpm in 5th @ 70mph, mines a refreshing change from that!!!! It's all swings and roundabouts, I prefer the mpg!

I doubt you'd have any luck getting a refund but yes the graph does not represent what your car is like at all.

The results from the recent Briskoda/JBS RR day should make things clearer. The JBS dyno is regarded as one of the most accurate in the business and deal exclusively with VAG. The last 3 cars on the list were running standard software.

Thanks for all you comments, I'll make a home for the graph in the bin then! I WILL get my money back, I always do!

It's annoying as I am having my car remapped in a couple of days and I'll not have benchmark to compare it against! :thumbdwn:
