Not sure if i'm posting in the right section but want some advice:
Just had a new turbo fitted and have much more power than before :driver:
I have tested the car, all in the dry so far and have had traction/torque steer issues. First time was on a flat stretch of road and in second put my foot down and got wheel spin with the esp kicking in.
Then on another road put my foot down and as it was a bumpy road got torque steer.
My question is I was thinking about better tyres but then i would get more torque steer. Again with WALK more torque steer. I then thought about a better diff but that would cost £££.
Any ideas?
Also this is standard so going stage 1 would be worse i guess. I could get a 4wd instead I guess!

.
From what you are telling us, I think that your first thing to do is to use your right foot more smoothly and progressively. Please don't don't interpret my words as any form of insult or piss-take - I believe I am giving you good advice.
I assume your tyres have plenty of tread and are correctly inflated.
I wouldn't do any mods to your car until you have mastered how to get the standard power down on the road. Power is useless without traction.
-

....A new turbo of the same type as previously, or a bigger turbo?
On what engine in what car?
-
The front tyres have about 4mm of tread and the rears about 7mm and I will check the inflation but I thing they are ok.
The turbo is new from VW so would be the K03 I guess as the car is a standard mk5 GTI 2007.
-
I wonder if a custom map would help?
-
Also i mentioned the 4wd as this would enable me to put my foot down and get full traction?
-
I think you are getting a bit ahead of yourself with 4wd. unless you plan on getting a different car all together.
What brand of tyres do you have?
And are you trying to get all the power down from a standing start?
-
Was considering a mk5 R32 before and is still in my mind but i really like the GTI.
Yes was trying to pit the power down from a standing start, my car is a manual by the way.
-
Well i think as Robin says you need to be a bit more progressive with your right foot. Unfortunately a front wheel drive car will always struggle to get the power down from a standing start. By being able to ease the power in when you have enough grip you will be able to get much better acceleration.
However if you are looking to mod the car you can fit WALK, uprated engine mounts, better suspension and if your really struggling a limited slip diff. But for a standard power car maybe just improving your driving technique would be a worthwhile improvement.
Same as Robin i dont want to insult you, just trying to give advise :happy2:
-
All advice gratefully received :happy2:
I have test driven lots of cars but as for owning this is the most powerfull of the lot. I guess I need to make a decision on whether I stick with the 2wd and adapt my driving and maybe mod later or look at the 4wd option.
-
Stick with the GTI :happy2:
In time you will get to know the car better and be able to control the power better. Also if you do start modding in the future the GTI has alot of pottential when it comes to modding :happy2:

....Adapt your driving. Rather than start by spending money on performance mods I would consider doing an advanced course such as CarLimits (in your car on an airfield) or Drivetrain (in your car on public roads). It's like remapping your brain (especially Drivetrain) and will stay with you whatever you drive. I use Drivetrain techniques every single time I drive - It's based on The Police Driver's Handbook and the instructor is a very highly qualified Police Instructor.
I had never owned a FWD car before and decided to do a CarLimits day early on. 4 of us from another forum did it together, all in Mk5 GTI's.
CarLimits is more about the car's limits and Drivetrain more about your driving limits. A much better investment than any car engine remap!
But start off by training your right foot :happy2:
-
Limited slip diff.
-
Spend some money on some race driver tuition or see if you can get some form of remap from Revo and use their linear throttle settings.
A friend of mine in a non VAG environment went to the n'th degree of power, weight reduction and brakes and i spent lots less having the race driver tuition and was slightly faster
-
Limited slip diff.
....An excellent mod for later but he hasn't learnt how to use his right foot yet.
-
All good advice. You shouldn't be getting much traction issues on a standard K03 GTI. Once you do start tuning though an anti lift kit and some good suspension like the Bilstein B12 will help with traction and handling the extra power. A limited slip diff as later on.
-
A good read. I was wondering the same as the op before

Fair play to redrobin you put your point across very well and hats of to the OP for being gracious enough to receive it. I haven't been on any driving courses, however as this is my first performance motor I have learnt a lot myself.
I no longer try planting my right foot and turning the steering at the same time....the tyres simply can't turn and car and put all the power down at the same time. Sounds simple but coming from a "shopping trolley" there was a lot for me to learn.
If the roads are even slightly damp I don't bother with standing starts as I'm simply burning mm's of tyre tread. Ive learnt to get the car of the line first before applying more power.
Not trying to be patronising but this wasn't immediately obvious to me....six months later I don't even think about it!
-
The reason I posted was because I was suprised that I was getting wheel spin in second gear on a dry road with a standard car. I was considering a stage 1 remap but to me it sounds like a bad idea because I like the idea of being able to put your foot down and know that the grip will be there. I guess the only way I'm going to be able to do this is to get a 4wd car.
I do like the GTI though so will keep it for now but I will be interested at 4wd offerings in the future like the S3, Golf R etc.

LSD and you won't miss 4WD.

:drinking:
....Agreed :happy2:
More fun too. Downside is that it ain't cheap and more worth it if you plan to keep the car as it's not really a mod you can sell on separately without the whole gearbox.
-
Yes, Robin. Cost is one main reason why many guys fear retrofitting a LSD.
But going the ED30/35 + LSD route isn't more expensive than buying a comparable R32/Mk.VI R.
@ all: Keep in mind VW is going to supply the Mk.VII GTI with a true mechanical LSD called 'VAQ' !!
:happy2: :happy2: :happy2: :happy2:

....So VW realised that their Mk6's 'electronic' LSD simply wasn't such an effective solution afterall.
-
The lesser Mk.VII now all come with the XDS, the GTI will come with the VAQ (hopefully
at no extra charge) and again the R comes as 4-motion.
Conceivably for other variants like the GTD the new VAQ is going to be an option.
I have to say while XDS being no true LSD it isn't that bad for a hot hatch besides
track use. I wish I had XDS on my Mk.V. I know it stresses the front brakes, but it
also helps cornering.
:wink:

....XDS is certainly better than nothing.
How does it stress the front brakes? And does a Quaife mechanical LSD also stress the front brakes?
-
Of course a mechanical LSD doesn't stress the brakes at all - a huge advantage on track.
XDS works similar to EDS by appyling some brake force on the inner wheel, but earlier and
much smoother. Nonetheless similar principle. All that using the brakes will stress these
when used extensively (which on track will be the case - again and again).
Good thing for a DD, but double-edged on track. While it helps accelerating out of the first
couple of corners it will quickly (co-) cause raising front brake temperatures. With stock
brakes a huge problem. XDS will at least increase brake wear. With BBKs and proper ven-
tilation not that much of course.
-
^^^^
Then that's another bonus in buying a Mk5 GTI and adding a mechanical LSD (Quaife) aftermarket, plus the BBK :happy2:
-
You said about the tread levels, but didn't say what tyres you actually have? That would be the first thing I would be looking at.

^^^^ This is something which many modders don't realise and upgrading brakes is often overlooked. Having powerful brakes makes the difference between joy and tragedy.
A car doesn't ever know whether it is being driven fast on a road or a track and behaves according to its own limitations (and your driver limitations of course). The detailed setup for track can be different and also different for different tracks even, but fundamentally I believe that mods for traction apply in all environments. So mods such as a mechanical LSD are very useful anywhere.

X2 ^^^^ Well said Robin ! as you mod you realise what works, until you do you dont know!
-

3rded, most important question that hasnt been answered in this thread!!
No point having a spaffy diff, WALK, KW V3's and Fernando Alonso behind the wheel if the car is running on Nankangs lol ...
Wheelspin from a standard Gti in 3rd would suggest that its running on budget tyres imho.

4th'd!
A car's only contact with the road are 4 small patches of tyre, each about the size of a CD/DVD disc. It's pretty amazing that good tyres achieve what they do. As for high performance motorbike tyres... Well, just look at Casey Stoner!! :notworthy:
