Hi folks,

Having just driven and ordered a Fabia vRS estate, I was wondering if anyone on here is privy to any information regarding the 1.4 TSi "real" power output (has had their standard car rolling roaded) and the cars real acceleration stats.

I know the Skoda brochure says 0-62 in 7.3 secs but I cant see how it can really be 4/10 sec slower than the Polo GTi. I've not looked but is there much of a weight difference, or is it all just marketing spin to make the much more expensive Polo with the same hardware appear faster and thus attempt to justify it frankly ridiculous price??

Also very much aware that VAG have always been rather conservative about their "real" power outputs and that the quality of UK fuels means that most of their engines put out another 8-10hp more than their official rating, particularly the diesels. Was wondering if the 1.4 twincharger is the same.

Thoughts please! Cheers.

Christ sorry I keep doing this...thinking of other things to ask. Does the vRS given its power output have Launch Control? Wondering if VAG have done away with this feature now, but it always used to be a built-in function on any DSG cars with 170ps or over, diesel or petrol I'm pretty sure?!

I dont buy this VAG underestimate their power. Its rubbish. What you have is irregularities and variations between climatic conditions(ambient temp/air pressure all effect performance), then there is the type of dyno and how well its been strapped down. Some dynos read 20-30hp higher than others etc. I for one only pay attention to dyno dynamics rollers, as they are the most consistent and realistic i have seen (alot of people dont like thm though because they cant willy waive with big inflated dyno figures down at the pub).

Ive seen many many many VAGS get exactly the stated output on dyno dynamics rollers. yet on others like AMD and superchips all of a sudden these cars suddenly are making 10-15hp more than stock :wonder: :wonder:

not to sure on why the polo states a quicker 0-60. A potential reason could be that the polo GTI and Cupra run on 215/40R17 wheels, whereas the Fabia runs on 205/40R17. The wider tyres on the polo/ibiza should give more grip. Less wheelspin = faster 0-60.

Mardon is going to do a load of in gear acceleration tests on his Cupra prior to getting his Revo map. That way we have a good comparison as to where them actual gains are.

REVO have released this graph of their stage 1 output.

Theres a dyno graph thread on seat cupra net as well, although alot of guys have used AMD for their power runs, so potentially a bit micky mouse.

Reference mapping at the moment, some of the early cars can be remapped via the OBD port or with the ECU removed and piggybacked. However a couple of the tuners have said that fabias/ibizas/polos built after Dec 2010 have new encryption codes on the ECU that the tuners cant bypass as of yet. From what i gather it wont take them to long to develop a way of bypassing the security but as always its another setback.

makes the decisiion on what to do first easier for me though lol

reference DSG. On the previous cars with the DSG 6spd wet box, the DSG remaps from GiAC and REVO allowed them to use launch control. Not to sure if it was available to use as standard.

According to Will @ Ptorque they are about to release their own DSG7 remap now. He hasnt expanded on the ins and outs of what will be changed and or actiicvated. im sure if enough guys pester him, he'll release the info for us

HAve mentioned this o REVO as well. they will eventually release a DSG7 remap, however its in a development queue

Dyno thread on seat cupra net for the 1.4TSI

spoke to my cousin who works at auto express about buying a brand new VRS and he said that thier testing of the VRS were 0-60 in 6.8 unlike the 7.3 quoted...

of course it depends on what road surface they were tested and even more so on the driver involved. Alot of variables, but id imagine in a straight line they were neigh on identical (although the fabia has the aerodynamics of a brick, but that'll only come into effect @ high speed really)

Well granted they probly used a track to do the testing, but he said that all was neded was to stick it inot drive and slam on the loud peddle, thus little/no driver input at all really...

On Saturday at a SCN Rolling Road meet at Motoscope, there was member with a new Polo GTI. It made 178.2 BHP, 187.7lb/ft.

DSG cars had to go last, but I had to go before the end, so I missed him.

Hi pipsyp, yeah...gotta say I agree with Janner. In reality I don't think VAG engines are any different to others regarding power outputs. It's pretty much the same for all of them in my experience. I've dyno'd cars and more lately motorcycles that I have worked on for friends and/or own. Power output can vary so much whatever the make of engine when compared to manufacturers figures. There are just so many variables involved. In my case I recently dyno'd a motorcycle and found it to be well over manufacturers figs (153ps, 8ps over manufacturers figs and not uncommon), yet it was standard set up on the bike. Later that same day it was dyno'd again by the owner on the same dyno machine and it showed it was down on power (140ps, 5ps under manufacturers figs). Yet we both rode the bike and agreed it didn't feel or go any different. We were talking about a 13ps difference here on a bike developing 145ps in standard form. The variables were mainly weather...temps and humidity which had changed considerably as the day had progressed. The bike was untouched since it's first session and the dyno had been fully calibrated that morning and had done no other work since the bike had been first dyno'd in the morning. I've had just the same with cars too. One thing I have noticed is that smaller engines with high specific power outputs are more affected in this way than large engines with big outputs. So the 1.4TSI will have off days and good days too on that basis.

Also pretty sure that all forced induction engines are more prone to this sort of weather-based issue, as the density and temperature of the oxygen available has a significant effect on output.

Here is my standard car 180PS on the Awesome Gti rollers

194BHP and 180Nm with 0-60 6.39seconds

With a revo this went donw to 5.1 seconds and 13.9 Quater. (Measured at GTi Inters).

Why the different rpm when the torque kicks in?

Cheers all for your responses. Agree regarding the dyno's/weather conditions, some of the figures thrown about by some tuning companies are probably not 100% accurate. What I do find strange is that on the Superchips website on (I assume) the same set of rollers a Vauxhall 1.9 CDTi 150 engine just makes 150hp (as quoted by the manufacturer) and about the right torque but most if not all VW engines made a bit more than standard. This is a bit odd isnt it?

I have to say as well my Wife's old Ibiza 1.9 PD 130 Sport seemed plenty quicker than a 1.9 CDTi 150 Astra I had for a time which really it shouldt have been being down 20hp and a reasonable slug of torque. Both cars were completely standard as well. I know there would have been a weight difference but it wouldnt be significant enough in my mind. An interesting thought I guess?!

So would we all agree that most vRS will probably make 177ish hp (plus or minus a bit) and it's quoted 0-62 is probably a little conservative. I reckon if the Polo can just crack 7 to 62 I dont see why the Fabia couldnt too. Sure its probably not as good aerodynamically but it woudnt matter at these speeds.

Can I also assume the 7 speed DSG cars do not have launch control (like some of the higher powered 6 speeds)?

No launch control on the dry clutch 7 speed.

Mike Austin i'm not sure what you mean? The two different figures are Wheel HP and Fly HP.

EDIT, I see what your asking and TBH I dont know the answer.

ive seen the results for this day. looked like a very inconsistent day, with guys reading really low, really high and bang on.

EDIT, I see what your asking and TBH I dont know the answer.

There is something peculiar about the red curves. It is not just where they start (where the torque 'kicks in') - they slightly double back on themselves at the beginning. Otherwise, power, torque & rpm match OK. (In the units on these plots, power = torque*rpm/5252.)

No idea dude. You'd have to aske Awesome Gti on that one.

FWIW Awesomes rollers have been giving out very large figures since their change to REVO. Alot higher than what other REVO cars make elsewhere,

The RR print out was done back in Feb last year when they were still APR.

So when I get the Revo put back on i'll get a good indication of if they are over estimating.

But the remapped car matches the figures in real life so i'm happy. No problem accelerating away at 40/50mph from standard VXR astra's and old shape focus ST's. It leaves the Clio 200 with ease as well. All these in gear on the move not off the line.
