Get the car on JBS's rollers and lets see what it makes there

Chris

Chris I allready told you theres no point as I'm not using Ultimate deisel no more

:(

so I wont have 6months of using the stuff to improve my car :thumbdwn:

Most rolling roads take these losses into account by testing rolling resistance too - not massively accurate but a reasonable indication.

Without taking the engine out and running it on a bench you'll never know. It is worth bearing in mind that the 128bhp quoted by Skoda (130ps) is their figure of what an engine built within tolerances will produce at the very LEAST' date=' it would be neither impossible nor particularly improbable for a well maintained, broken in example running higher grade fuel to be producing 10% more IMHO.[/quote']

cheers

why cant other people on here be as trusting

****es me off when everyone starts when your trying to put an honest opinion and figures up

I think my reading of 136@ wheels was down to a combination of factors

Fuchs fully sync oil

26k miles on clock

ultimate Deisel

ranting the F**k (redline the car abit' date=' through my driving style)

(supposed to be good for a deisel)

also I got Goodyear eagle F1 tyres

which would mean it would grip the rollers better (maybe transfer more from the engine)

I also warmed the car up nicely and for ages before if that affects the results[/quote']

1) VW PD oil is of a similar quality if not the same

2) Fair point, but that doesnt account for a 26 bhp gain

3) 1-2 bhp at the most, someone on here did a comparison between the 2 and got 2 more bhp on well lane turbo centre's rolling road

4) not going to account for 26 bhp again, infact probably not anything other than cleaning the shít out of the engine.

5) i'm sure most tyres will grip to a rollers just fine and transfer the power, most people on here have similar tyres or argueably better and get no more gains

6) Warming up the car won't do much, infact too much warming will cause heat soak and reduce peak power.

I'm not having a go at you Tigger, I believe your car may produce 136 at the flywheel if it's a dime, and I don't doubt your figures; but remember some rolling road's are very optimistic, not necessarily the tuners fault. But Skoda would get one hell of fine if they intentionally mis-represented the power of the PD130 to lower the insurance group. It would also steal sales from the PD150. And last but not least, go to http://uk-mkivs.net and see how many standard PD130's get 156 bhp and you'll be laughed at.

HTH somewhat

I was there that day , and saw his car get an indicated 136 at the wheels.

There were a fair few standard cars there that only got what the handbook says they should including a standard octy vrs that got about 160 at the wheels.

As a result I'm inclined to believe his car does make over the 130 claimed figure and I'm as sceptical as anyone about certain rolling roads that always without fail have every single standard car at 10% more than they should do.

Hmmm, so his car has a PD150 lump in it then.

Either that or it's by far the most powerful PD130 ever!!! any mods?

Sorry mate, i'm a none believer on this one. I believe your figures to be true, but I would question the rolling road it was done on.

I don't think there was anything changed from standard other than the fuel.

Still , look at it this way.

Everyone agrees that not all PD130 engines are bang on 130 bhp. The way it's driven will make a difference and the 130bhp is a fairly conservative figure for a new engine. Once it's run in and loosened up there can be a few bhp more , so standard engines are most likely between 130 and 140.

The higher quality fuel can make a small improvement. 3% is another 4bhp on an engine of this type.

Rolling roads are big mechanical devices that don't always give the exact same reading for the same vehicle. Even if there's only another three percent error that can be say another 4 bhp either way.

Add all those up and you are very close to getting an indicated 150 bhp at the flywheel on a good day with a good engine - so 135 at the wheels which is what tigger (and a dozen or so other briskodians) witnessed.

My car made 147 bhp prior to the remap and 191 afterwards (with other mods). I have seen 201 bhp on one rolling road and 176 on another. My inclination is that my bhp is more like the latter.

skoda quote 130 ps or 128bhp in old money at the flywheel so allowing for the often quoted but highly inaccurate 10-15% transmission loses thats about 109-116 bhp at the wheels , it certainly doesn't feel like just 109-116bhp at the wheels on the road , i would imagine a galaxy or sharan would be positively dangerously slow if they had that small amount of power , drove a galaxy pd130 today and other than the body roll it went pretty well , my vrs had 132-133 bhp on awesome rollers last saturday and as i've said before in the awesome rolling road thread i'm quite happy that it was a reasonably accurate figure , if theres ever a rr day at jbs or where ever i will endeavour to get it tested again to see if theres a huge difference

Back on topic - I thought the Leon FR had the same engine as the Fabia i.e PD 130 lump and it's the Leon Cupra that has the PD 150 lump tuned to 160 bhp???

I don't see that they would only have 10 bhp difference between models.

Just searched it on the net and it looks like the FR Tdi replaced the Cupra Tdi in it's last months....

They dont, PD130 - 130 bhp PD150 - 150 bhp PD160 - 160 bhp

Leon not nice - Furby much better!
