Surely if they ran the dyno and achieved near as possible stock figures, without riding the rollers, they are operating the equipment properly.

exactly my point.  Pretty much every tock car ive seen on RR days @ JKM have been ran the same and made stock figures.  Same here @ sanspeed, IAMotersport and Alan Jeffreys (all dyno dynamics that ive used)

but we wont get into the dyno argument again.  got told off last time :rolleye:  Im happy as long as i have consistency in how the car is ran anyway

I want a Polo GTi now :drool:

May go test drive one and sneak a Revo flash on it when the salesman isnt looking.

For a 1.4tsi to dip into 12's it's gonna have to be quicker than a stage 2+ s3 rolling. Can it do that?

Yes, exactly. You dont need to climb up the roller to make accurate power, its when the car is strapped too tightly that power figures are restricted. As long as its not strapped too tight you will make accurate power wether it leaves the rear roller by 0.0001mm or 30mm.

that clip above is a stage 1 car with no intake.  he might think hes got 225hp but he doesnt, its more like 205hp on the standard intake. 

Give him stage 2 remap, an intercooler, and  the downpipe or even a decat and he'll have another 30-35hp to lose his final 0.4 seconds to get into the 12s.  i reckon he'll manage it if he goes nuts. 

Also once the clutch packs are released, REVO are planning to do more aggressive maps as they will be able to manage even more torque.

Ill never manage it in mine,as im not willing to strip the entire interior out.  Ill go for a stage 2 with suspension and sticky tyres, but wont go any further.  ill be after the 13s

Anner if stage one only gave him 25hp there is no way he's gonna get another 30 from a cooler and exhaust. If you reckon the stage1 advertised power is inflated then ao will be the stage 2....

fair point,

but an intake will give gains of around 10hp commonly on pretty much all turbo powered cars.  Theres also plenty of before and after graphs from ITG and forge showing the actual gains their intakes gave on the 1.4TSI and thats without a map tweaks.  Then going off of the K03 TFSI stage 1/2 outputs id say 20hp gain is a reasonable with a turbo back exhaust and stage 2 map.

REVO reckon power is having to be really reined back due to the stock intercooler being unable to cope with the temps. 

Ignoring peak power figures if you consider the car in that clip is only stage 1 with a panel filter for power gains, it'll be substantially quicker with an intake, decat downpipe intercooler and stage 2 remap.

Also the stage 2 Dyno graph from AMD on post#1 is a watered down version of their final stage 2+ map as well.

REVO are making 3 stages of map.  stage 1(stock cars as always)  stage 2 (the one in the AMD dyno graph) which is for cars with a downpipe as an upgrade, and their doing a 2+ remap (not released yet) for cars with the full setup.  The guy whos car was ran on that dyno graph is heading back to revo soon for the update i believe.

From what i gather theres a pretty substantial difference in performance between the stage 1 and 2 maps, from the guys who are running it or tried it.

We'll soon see how they get on, loads of the cupra guys are about to get the full set up fitted.  just a hold up as miltek try and meet the demand for the exhausts.  it'll be intesting to see how the guy in the clips manages with stage 2.  Hes already matched the '360hp' REVO stage 2+ demo Leon (15th on the 1/4 mile league table) despite only having '225hp'

fabia vRS kerb brochure states the kerb weight is 1243kg i think the ibiza and polo are lighter again.

edit

Couple google searchs reveal a general consensus that the polo is 1184kg :surprised: http://www.volkswagen.co.uk/volkswagen-world/news/220 so if stage 2 is 236hp that would make them  199hp/ton

edit#2

press release info on the ibiza cupra show a weight of 1174kg.  so 236hp = 201hp/ton

and my lard ass fabia would only be 189hp/ton :grin:

Audi call the engine a TFSI, but it's still the same engine as the Polo/Ibiza/Fabia. It's just a company brand thing, like they call Haldex 'quattro' on some models.
Audi call the 2.0 petrol engine TFSI too despite it being the same engine as the mk6 GTI/Octy vRS/Leon FR FL

In short currently VW call all their turbo petrols TSI, Audi call theirs TFSI and SEAT and Skoda just do as they're told by Mother in Germany.... :smiley:
