New GTI Turbo Specs

[bullsta]

Hi all,
currently drive a chipped Mk4 GTI and love it.
Looking at a possible upgrade shortly to the 6R Polo.
Anyone know what turbo they run and if they can cope with a chip CAI,exhaust etc.
From reading i,m happy the DSG is up to task,just don,t want to mod if the turbo runs out of puff like the KO3
Any advice greatly appreciated.

I just orded a new polo gti. comes in 2 weeks they have a twin charger (supercharger and turbo in one)
APR do a chip, cold air, bigger intercooler and soon to come exhaust.
chip takes it to 149kw at the fywheel and the website says between 9-11kw for the intercooler. intake will add a couple more and the exhaust should be at least 15 or more so all up you would think round about 175kw at the flywheel.
APR havnt seemed to have any problems with the twin chrager that iv heard of buy do a search and you may come up with somthing

Most of the major tuners are able to upgrade the 1.4tsi in the 6R Polo GTI. They certainly are a cool little car to drive.

Having said that, given all of the warranty claims and engine replacements going on at the minute with stock standard cars Im not convinced it is a good platform to begin with if youre looking to tune it.

majority is to do with break in of the engine, all my mates drove them with a degree of gusto and now there about 3000km old they use no oil and run like a dream. others that have drove them like a granny for the first few months are still using oil.
Im sure there are other problems people are having like any other car does but i wouldnt let that turn you off.

We have tuned hundreds of the twin chargers in Australia - I wouldn't be at all concerned about modifying or chipping the vehicle at all.

Afraid of engine breakages? - sorry, that's a load of bull - only people who don't technically understand the workings & calibration of the car would say that.

The Turbocharger is a K03 based unit standard, we already have a K04 + unit on our own test car and have thousands of hard miles on it.

We are approaching over 200kw (crank) out of ours on 98 ron fuel. - It's a rocketship & those that spotted it running at the VW Nationals last weekend - it's lap times speak for themselves

Guy,
What sort of numbers where you getting from a stock turbo out of interest.

Im sorry this has nothing to do with technical knowledge.
I would suggest if you understand this engine better than VW do you might want to help them out a little. In the stock calibration they are having all sorts of problems and clearly have been incapable of rectifying it to date.

I am merely saying that if someone is looking to purchase a car with the thought to modifying it they would be best to look at a car equipped with a different engine. To me its irresponsible to pursue a tuning program with the possibility of getting in the middle of someones warranty claim.

I agree with Tim wholeheartedly on this but with the thousands of tuned 6R gti's around the world that all seem to have less issues (except 1 I know of) than un-tuned cars, I think tuning is actually a pretty good prospect. I might have even overheard from a little bird, along the grapevine, off a mate in the know, that the stock tune is really rubbish and you're actually going to be better off in the long run with a tune.....

Onthis motor, the only breakages so far I personally know of is one car that destroyed a piston but there is conjecture regarding the legitimacy of the owner's claim. Aside from piston rings not matching cylinders very well on some cars (mine is 23000kms old and I have topped up, i kid you not, 2L of oil) I think these are actually one of the seemingly better built VW motors. Still not any match for the mighty 1.8 boat anchor though but that is just one of those brilliant engines that should be revered.

Yesterday I had an interesting conversation with the mechanic at Euroclass about oil consumption and piston rings.

Long story short...he was speaking of a customer's older model Audi TFSI engine which had major oil consumption issues since the day it was driven out of the showroom. Anyway at the time – I think he said 2002 – VW had run out of the replacement piston rings as they weren't no longer making compatible rings in that specification, Euroclass took an alternate approach to the situation and commissioned a fitter & turner to machine – from a different type of metal – a set of rings to match VW specification.

Once these rings were installed the Audi in question not only racked up another 150,000+ km, but it did it without any evidence of oil consumption. The oil never moved on the dipstick.

Is it at all possible that the current problem with this engine lies in the potential unmatched difference in metal porosity between the bore and that of the factory piston rings?

I welcome any feedback from engineers who can shed any light on this.

I take it you have never disassembled a twincharger motor or examined the ECU code then

There have been many, many more A4 / A5 / Q5's that have had engines replaced than twinchargers (and I'm sure a hell of a lot less sold) - If you were not going to tune a car that MAY have a problem, then you shouldn't tune anything.

I have heard of Golf R engines failing, TSI engines failing & MKV engines failing - as with the twinchargers, its RARE, but it does happen. I suppose you would never tune a car with any form of DSG gearbox?

Not sure why you want to have an argument but anyways ill explain my stance in simple terms so maybe you can see a little bit beyond your own ego.

Nope ive never disassembled a twin charger motor and probably wont.
Youre right any engine/component can fail and there are some of the Audis that are having horrible oil consumption problems. I would be cautious modifying those too. Ive always taken a responsible stance and told people to ensure their cars are healthy by putting some kms on them before getting a tune. Again mostly so they can get any warranty concerns sorted out before hand. The last thing I want is for a warranty to be denied but not caused by a product that I sell.

Where we differ is that I have nothing invested in this platform so I am free to give an honest opinion of which car to purchase if youre looking to modify it. Keep in mind the original poster in this thread is just weighing up options as to whether this is a good car to use as a base to modify.

One thing to remember is that I am here first and foremost to be part of the community. I enjoy offering advice/opinion where I feel it is of assistance. Im not trying to sabotage your business. Im not trying to say a anyones car will spontaneously combust due to an aftermarket tune. You are allowed to disagree. I draw the line when you start attacking my credibility.

My point is clear. Due to the high number of warranty claims being experienced on the twin charger engines I wouldnt recommend playing russian roulette with ones warranty. If you disagree with me that is fine but dont come here trying to make out that I dont know my arse from my elbow when it is you that wishes to ignore the facts.

I entirely agree with Tims post , why would anyone rush to get a aftermarket ecu tune if one knowingly knew that their particular ride had issues such as ( oil consumption etc ) my car has gone through 3 liters of oil having only done 3400 km , i for one wont risk my warranty until this issue is sorted out .





Why play Russian roulette with your 3 year warranty ,

Hmmmm, common theme starting to emerge within tuning threads. Said it once, say it again. The other areas of this forum have enough mud slinging regarding tunes and tuners, namely being started or inflammed from one camp in particular and it's associates. While not a moderator, I theoretically have no ability to delete posts but so help me if this sh*t continues in the 6R section of the forum I will speak to the moderators regarding the warning system and/or banning of forum members for inciting this kind of rubbish in our section. If people want to play dirty, go do it in the golf sections, plenty of egos over there to go play with.

Now, semi back on topic, ATYPIC, it's not a question of possibility but moreso reality, though it's very very unlikely that porosity is the issue.

Actually the oil consumption was fixed in my car after getting the piston rings replaced... Never droped a single ml of oil in 2000kms. But it started to sound like a sewing machine and 2 weeks later connecting rod @ cylinder 1 was totally worn out and piston from cylinder 4 also failed causing low compression.
