Oettinger POLO GTI Dyno 202whp or 151kw MODS??? YOUTUBE

[instigator]

true,
all 132kw engines used the K03s turbo.
and the older 20vt engines used the normal K03 turbo.
K03 being capable of reaching 210Hp - 215Hp at max!!
but later on, all the more recent 110kw engines where equiped with the same K03s as used on 132kw model from A3, TT etc.
only downtuned to 110kw.
they basicly used the K03s to replace the K03.

so i'm 200% sure that the Polo GTI/CUP are using also K03s turbo's.
check the numbers on it and you will see
with a full 2.5" exhaust, airfilter, good intercooler and custom mapping they easy produce around 220 - 240Hp
and i have seen even much higher results but those are rare to be seen and not safe to run imho.
btw, those results could never been made with a K03

about the software.
i am from Belgium and i don't know if you know any chiptuner from over here?
maybe you know JD engineering (Jeroen Dik), he's from Holland?
about the best you can get for (custom)mapping a 20VT engine in europe.
he only does VAG related vehicles but he is specialized in 1.8 20VT.
tons of experience with those engines

Hey Instigator, you are spot on with the power levels & safe limits - nothing beats a bigger blower he in the end.

Sorry, don't know any tuners in Belgium, but I'm sure with all the VAG cars over there there must be someone who knows what to do!

To look at An Australian dyno plot vs a Maha / Bosch / Dynojet or similar, you will find ours reads 10 - 20% lower too.

[instigator]

10 - 20% is pretty much, so the polo you had was more powerfull than the dyno readed it?
why did you do this?

ps: what is youre opinion about putting a K04 on a polo?
did you think it was worth it or do you say, better go for something bigger, like GT28RS or so...?
i guess in lower RPM a K04 must be awsome, but in higher RPM the garret will be alot more powerfull.
wich one would you prefer?
keeping in mind that it's still a daily driver...

I think Guy is referring to the different brands of dyno, and even the calibration of each Dyno of the same brand. So a power figure from X dyno is pretty useless for comparative purposes, quarter mile (trap speed and time) seems to be the most appropriate gauge for power. I'd had my previous car on a few dyno's which would read in excess of 20kwatw difference between them, which is within the percentage Guy referred to.

I Think the K04 upgrade for a Polo is great - my only ever beef with the 9N chassis was the ability to handle that power

Tyre size
Firewall flex
Damping
Braking
clutch
gearbox

To use the power well & drive it hard (eg - on the track) - you need to consider the above items.

The k04, I would say, it is a very good upgrade.... Totally plug and play, I love it when I had it on my car. Excellent power range, recovery, at the road or highway it was fantastic. In fifth gear, in lower rpms the car jumped when the hammer was dropped. It had 1,6bar of boost at 5500rpm, above that the boost fall to 1,1bar.

The weak point were the 3 bolts holding the turbo on the exhaust manifold, I solved my problem machining 3 longer bolts in 4140 steel with steel washers. I never had a problem after that.

And when I had it, I was with the Forge intercooler… by the way, it is not that bad…

With the GT2860 you have a hard core engine… you need to work at higher rpm for a descent engine response… and it is not a big turbo… The car can be for daily drivers… but for those who are not afraid to shift gears.

So your saying the Forge intercooler is not that bad

Did you loose a few PSI after you installed it

[Plautos]

I never measured it... But I know the turbo was boosting what it was supposed to boost.

I saw lost of boost with the GT2860, 0,2-0,3bar, however it is a gigantic turbo compared to the k04, much more air flow and power delivery. I´m working with APR for a new tune in my engine ECU, I need it because my tuned intercooler gave me a very impressive result.

If the Forge intercooler was holding boost, the boost was not going to fall at higher rpm, so much and so quickly.

I saw the research that Guy send me about the intercoolers comparison, it was a very good job, however the k03s or k04 will not flow the air needed to create a restriction, in my opinion.

For a basic intercooler you must calculate the area… if you have 60mm tubes and throttle body… you have an area of 2828mm2 plus 20% we have 3393mm2…. The Forge intercooler had 7 columns of 60mm by 8mm, recalling from memory, I’m not sure, but it is close to that… the intercooler have an area of 3360mm2 … It is inside the expected… a good intercooler need to have 15 to 20% more area than the tube area.

I don´t have nothing to complain about the k04 and the Forge intercooler. I think they are two great upgrades.

I never measured it... But I know the turbo was boosting what it was supposed to boost.

I have some boost logs. With the stock ecu map - there was no difference between spec & actual boost with the Forge FMIC.
With the stage 1 software - the actual boost is lower then specified over 5000rpm - but I think that could be because the stock turbo can not hold the boost at the required levels above that rpm.

Interesting, so really 150 fwkw give or take 5kw is the most to expect from a k04-001 with the core upgrades? i.e tune,fmic,full exhaust and fpr?

Is the TT manifold and turbo swap a direct bolt on? I believe the TT has a K04-022 correct?
