Yeh what Mater is saying is correct. Keith at JKM said Carl and I have different code to every other Revo Stage2+ car they have seen and they wouldn't make more than that on the dyno. On the road it would put down the full 280bhp as the in gear times are the same to other Stage2+ cars with the different revision of code.

The torque curve I now have with the K04 will have smoothed out a bit - it's a bit uneven on the graph. On the road I couldn't possibly want any more torque or power it's just right and if anything too much. As an upgrade it's definately worth doing, but I wouldn't like to pay the full price of a brand new turbo kit.

I might take my camera out with me later and shoot a quick video to give you an idea of what it's like.

If it doesn't make the same on the dyno than the road, then what's the point in dyno testing at all?

So can I just claim that my car is 280bhp and 320lb/ft because it's the same as a Revo Stage 2+ on the dyno but it pulls more on the road?

No because your car wouldn't be requesting 1500+mbar over ambient air pressure which is what makes Stage 2+ do what it does.

Dyno Dynamics recognise this but unfortunately you need to be an operator to get the info.

about halfway down the page.

I'm sure if you ask Keith from JKM he will explain in more detail. I didn't catch the specifics when he told me and tbh I'm not bothered by it as it felt great on the road at Stage2+ level

Harry that's your before and after? Can you list your mods (not the brakes, I know about them )?

I remember you saying yours was Revo Stage2+ and HPFP yet it's only making 260bhp and 275lb/ftish whereas others are showing more torque with some Revo Stage1 maps?

It might just be my eyes but my graph appears to make roughly the same torque but for longer and roughly the same bhp but for longer, with smoother curves. And I don't have an upgraded HPFP.

For a proper comparison i'd use the same dyno and operator

Harry, please do put up the vid, hoping to get my ko4 sorted in the next few weeks.

Does anyone have any log results of their runs? Air mass figures for example? Boost is all well and good but air mass is where it's at.

Well the guy who is doing my remap says there is no need for the hpfp because he knows how to avoid the fuel cut. He also says i won't gain any extra with it on unless i get a high flow cat and system.

It can be avoided by not having high boost (and therefore high fuel demands) at low loads. There are better ways to achieve the power without cranking the boost right up.

General Question: Do Revo request an artificially high boost on their Stage 1 remaps that a stock car would usually not be able to meet?

I am not saying that this is a bad thing as there are plenty of safeguards in the engine management that would look at a high boost request and say 'well you can request it but you ain't having it because there is not enough air/exhust throughput or not enough fuel to give'. Add a mod that, even if it offers minor relief in the rate-limiting area and a map that will use it and off you go. It may also answer my earlier question on why Revo seem to, in general, have higher torque on Stage 1 than some other Stage 1's on minimal mods.

The reason for asking is that I stumbled upon an old thread on the vwvortex site that at the time the hpfp problem was being recognised and dealt with. It involved the guys at APR themselves. The statement (?true or not) was that under a 'normal' Stage 1 map the hpfp is not the 'rate limiter' to getting higher boost, it is getting air in/out of the 2.0 tfsi. Perhaps solving this with a CAI and cat-back only goes a little way before the need is on fueling via a hpfp mod..and then having a turbo-back (although I suspect the Stage 1 map becomes the limiter well before this even with Revo) and so on, if you get my drift.

Perhaps that is the reason that some see real advantages to a new hpfp and others don't i.e. those that have, already had at least a CAI and a map (requesting but not getting higher boost) in place before the change. Those that haven't either didn't have a map requesting the boost or had a 'rate limiter' with stock air intake / exhaust.

So that is my hypothesis which may be complete horse **** - can anyone with Revo Stage 1 and no other mods disprove this via Vagcom which I believe logs requested boost vs. actual delivered (or would Revo already have tweaked down to account for this)?

There are better ways to achieve the power without cranking the boost right up.

Do you mean mods or other map adjustments

..then, say, compare this one from the Feb 2009:

A bluefin Stage 2 with CAI, stock exhaust and no hpfp allegedly. As a reminder, I am on 231.3 bhp and a smooth torque curve maxing at about 240 lbft with a Pendle Stage 1 and absolutely nought else

i believe that was mine, from feb 2009 RR day at jkm iirc.

i loaded the stage 2 map onto the car just prior to doing the dyno run, the car was std apart from the carbonio ram scoop and pipercross panel filter. no exhaust and no induction kit and no HPFP. thew problem with it was that the map was designed with a perfomance DP in mind, so i took it off and reloaded stage 1 soon after.

reference logs, i had logs done on my car the other day, ill upload them as soon as i can. but i do remember the maf reading being about 198. im off to ITG to have them trial fit theie new intake on my car, so ill get a new reading then

Haha my willy is bigger than yours!!

My willy will soon be as big on October 19th as it's booked in to JKM:D. JKM won't fit second hand injectors so i went for new ones, my second hand ones if anyone wants them will go cheap.

i believe that was mine, from feb 2009 RR day at jkm iirc.

No its not. As it says on the printout it is a Chipped UK stage 2 map which the owner ditched in favour of REVO.

This is yours Simon.

I'm starting to appreciate just how good my map really is looking at some of these graphs!!

Ah but we haven't seen a graph of yours from JKM yet?

My standard vRS 2.0TFSI made 197bhp on their rollers.

I found this on JKM's website.

the next RR day at JKM ill be there in mine, so ill defiately get it done then. but mine is alot better now since going to stage 2+ as you can see from my amdessex dyno graph, where i had that massive hole in the power at 5000rpm. id say the delivery is quite smooth on mine now

Ah but we haven't seen a graph of yours from JKM yet?

My standard vRS 2.0TFSI made 197bhp on their rollers.

I'm going to see if I can book in there next time I'm down.. But either way the curves will be the same shape and it's the curves I was referring to, not necessarily the figures.

I found this on JKM's website.

Is that yours Hedge? Looks good but less torque than a K03 Revo stage 1 that everyone keeps comparing mine to

But that car has a very expensive gearbox to look after.

If you want to upset the apple cart you can use this one on very conservative settings.

So that's a K04 stage 2+? Again the torque is in the realms of the K03 stage 1, which doesn't seem to add up to me.

Thought the stage2+ Ko4's were making 350bhp+?

But it lasts for way longer. It must do to make 322hp as hp is a function of torque and RPM.

Thought the stage2+ Ko4's were making 350bhp+?

Depends how and where they are measured. On the day that's what that car made.

OMG he's making 0.7bhp more than me...no fair :(

Sorry Harry.

:rofl:

Looks like revo 3 is equivalent to stage 2+ on a ko4 car.
