So when you going to break the 300bhp milestone Steve?

have a look on the following link at the stage 2 revo'd cars make 300lbft+

What's the difference between Stage 1 & 2 then?

What's the difference between Stage 1 & 2 then?

OK I have answered my own question!

Revo Stage 2 software has been specifically developed to attain the best possible performance from cars with more extensive bolt on performance modifications. The Revo Stage 2 software is tuned on vehicle applications using a 4 bar fuel pressure regulator, a quality aftermarket performance exhaust system and a good air intake induction system. Furthermore, our Stage 2 software can be used with a de-cat exhaust for race or track use. The tuning style is more aggressive than the basic Revo performance software, and will typically yield 10-15% more useable power. Working in conjunction with an optional SPS device, Revo’s Stage 2 software can be finely tuned to each customer’s preference of drivability.

Stage 2 software produces 10-15% for power when used with:

• An aftermarket performance exhaust system
  
• A 4 bar fuel pressure regulator
  
• An optional aftermarket diverter valve
  
• And a Revo SPS

Most of our Stage 2 performance software is complimented by multiple performance programs, anti theft programs and user friendly variable table changes that become accessible when you purchase an optional Serial Port Switch. This will give you access to many different levels of enhancements built into the Revo performance software and ensure you are getting the most from any optional bolt on tuning accessories.

1.8 TSi Would be your best bet, It is much cheaper too. However I have driven a 2.0 TDi 140 in a VW passat estate sport and I was impressed.

So effectivly it becomes a moot point. The more money you throw at a car the more power it has. Not comparing like with like anymore though :thumbdwn:

Anyone know the different in torque rating between the vRS petrol and diesel? Do thsy bth use dual mass flywheels? Are they infact, the same?

Cheers!

What causes the tramlining is the amount of power you are trying to get down to the road, (Torque Steer). So if you are thinking of getting a 140 TDi and mapping it then you'll possibly end up still having issues.

I must say that I've never experienced it on my VRs.

tramlining and torque steer are completely different stu

surely we don't have to point the difference?

I was, perhaps wrongly, assuming that the OP was suffering what he called tramlining but was actually torque steer and hence considering lower powered cars.

Tramlining IMHO is normally caused by the road surface and not the tyres.

Nor me

Chris

its ok stu, i'll let you off but never make me do that again as i don't like it

this 1.8Tfsi in a "normal" octavia sounds like a plan, are they doing it in the 4x4?

Tramlining IMHO is normally caused by the road surface and not the tyres.

IMHE it's down to both and I've found that as tyres wear down (3mm ish) they are more prone to tramlining than when they are newer than that.

Be sure to wave when you overtake a slow old Panda :rofl:

I'd imagine that a 100hp would be quite at home on such roads

My humble Octy 1 vrs will do from 20 to 105 in 3rd :D

Whilst I'm sure the roads you mention are great for driving it doesn't really have any relevance to this thread title!

Back on topic please.

FYI there is a section on the forum for good driving roads and if you wish to start a new thread I'd happilly move the deleted posts there (just send me a PM).

Lol, no worries

I find the PD140 ample for overtaking. If the overtake is a little tighter, I'll use 3rd from 40 then to 4th at 70 (if I need that pace to get past). Otherwise just 4th. Even at 40mph, there is a fair amount of grunt in 4th gear once the turbo gets going.

I would have thought comparing the 1.8TSI to the PD140 would be a pretty close call? In which case the PD140 would probably win it for in gear stuff? I've not driven a 1.8TSI so I'm speculating here.

In my previous post I suggested a PD140 with DSG and dropping into Sport for overtaking - the reason for this is that Sport will normally select a lower (correct) gear for maximum push and saves having to floor the pedal and wait for the kick-down to take place as other have suggested. Generally gives a much smoother and faster overtake.

Tried both of these:1.8TSI in an Ambient(hatch) & a 2.oTDI Elegance (Hatch also)

Ended up ordering 1.8TSI Elegance - fuel consumption not as good - but considerably cheaper to buy( I don't do galactic mileage)

1.8tsi was amazingly smooth & quiet by comparisom and had a much wider & more linear torque delivery, even though the PEAK was a little less (borne out by the paper figures

Max :TSI 250NM : TDI 310NM (from memory) but the TSI is way wider & essentially flat from 1500-4200rpm wheras the diesel comes in very abruptly at circa 1900ish and is really past best by 3000rpm. My findings for what they are worth:)

Your findings are worth quite a lot . That's a decent comparison.

Hmm....

I got a load of back-issues of car mags from my dad over the w/end and from road tests of these VAG engines, it's clear that the vrs will be a lot quicker for the sort of thing I'm thinking of.

I haven't seen any gear ratio data for the octavia boxes so I can't directly compare the 'torque at the wheel' numbers, I would expect the deisel to have taller gearing than the petrol; comparing peak engine torque can be misleading.

while the tramlining is sort of off-topic it's the reason behind my question !

the tramlining would not be a problem on most roads, esp 'A' roads and M/ways etc. but I do end up on some poorly maintained 'B' roads which have a fair amount of old patched potholes and funny cambers from heavy trucks. I found that it was quite annoying/tiring having to fight the steering wheel on some of these narrow roads as the wheels tried to track the road contours. Thus, I find I want the vrs performance but not the vrs tyres !

It may well be that the 1.8TFSI engine is the solution. none second hand yet though - I'm lothe to buy a car from new, even with 0% interest from skoda.

PS. don't know what the potential problems are with remapping the deisel - the figures seem to hint at an extra 30 hp from the stock 140 engine - you do red-line a deisel more often than a petrol car - so reliability may be dodgy. I get the impression that remapping the TFSI engines is possibly more complex than the deisels due to the FSI technology and the different combustion 'modes' that the engine runs at different rmps and throttle points - possibly why there are fueling issues ?

It would be interesting to see dyno sheets for the 1.8 tfsi and 2.0 tfsi engines.

the 1.8 looks to be a less complex and 'cheaper' engine and probably doesn't rev as far as the 2.0 ? and the 1.8 may well have a less flat torque curve.

Erm there is no need what so ever to red line a diesel..... yournot driving a diesel properly if you red line it all the time.

On the contrary the 2.0TFSI is quite tunable. IMHO the fuel issue is just a case of not having a fuel pump able to keep up. I wonder if anyone has tried the S3's fuel pump ?

The issues with tuning are with the 170bhp TDI due to the DPF.
