Quick Polo GTI

[Kiel_GTI]

Tyre pressures make a difference. I haven't read through the pages of this so it may already be mentioned. Pretty sure the drag guys run a lot lower pressure then what we would drive around with normally

seconded. and because he is only running 150m his tyre pressures would probably be close to 25psi. a lot more grip off the line but lower top speed, which doesnt really matter as phenonemal speeds arent reached in 150m.\

also in that motor mag they get like a 14.4 or something down the 1/4 mile, whereas Kai has done a 13.9 with far less mods.

Yeah is 161hp atw or at the fly? In Aus we have 110kw stock at the fly, 161hp is 120kw...

If that was a dyno at the wheels figure, then your car is not the same we get in Aus. Did you buy it new or second hand? Maybe the guy before you chipped it.

As above, I have never seen 2seconds taken off a 0-100 time, but glad to be proven wrong.

Even on the Motor Magazine test, the 400HP Golf GTI got a 0-100 time of 6.2s... And that was specially set up in ideal conditions and all.

maybe im going senile but i thaught the golf 0-60 was 3.9 or 4.9 secs? meh ill read it again in the morning. i think youve done well mate , as kiel said its all in the launch. anyone know where i can practice without looking like a nob? ....i really hate doing that crap at the lights uless its some tool in a honda or a fagna.

Guy's red golf did like 6.2 or something, then the r32 turbo did 3.9s.

In regards to practising launches, best idea is private land, people get annoyed pretty quick by this stuff unfortunately. I found a good, wide, safe area near my house which is perfect, but then I don't want to kill my tyres too quick either...

thanks for the comments

and no, my car was not bought second handed, i was the first owner and i bought it new. so it's not chiptuned before.
and the Horsepower was measured on a decent dyno from a respected tuner here in Belgium.
and to correct it, i had 161Hp at the flywheel and 134Hp at the wheels.

also, for doing a dragrace, you have to stand still otherwise they can't measure the time and you get a red light.
so i do stand still before every launch.
but, i had one of the best and fastest reaction times in Ciney, wich means i reacted verry fast for the green light. if you go to fast, youre diskwalified...
so the fast reaction gives me a bit of benifit also.

my backseat was taken out and i gues that thing weighs around 30Kg or so.
and my Tirepressure is normally 2.2 bar. but for a short dragrace like Ciney, you only need 1 - 2 and a bit of 3th gear.
you never get to 4 or 5.
so for such a short dragrace i put my tires on 1.8 bar for more grip,
thats why i don't spin out when i launch at 3000RPm.
when my tires are on normal pressure i launch at 2500Rpm.
hard to tell how i do it exacly, but if you guys want i try to explane it and make a video of it...

and about the 0-60 from magazine's and other stuff... never ever correct...
i have had a swift GTI MK3 who should do 0-60 in 9secondes and i did it full stock in 7.5seconds.
same story with my old sierra who did it in 8.2 and they quote it in 10seconds or so.
so never trust those figures, if VW quote that a polo GTi can reach 6.5seconds stock. and the most people don't get to reach that time, they will complain to VW or think that their car is broke or something.
they allways give a slower time, a time that even bad driver can reach
and the reason why a pro driver only get 6.55sec to 60 with a chipped polo is maybe because it has to much torque on low RPM? don't know, or the guy is a great cirquit driver and not much of a dragracer?
don't know the answer, i do know that it's possible to get under 6seconds with a chiptuned polo

Interesting stuff, I'll have to test this one out.

And using an online calculator, 1.8 bar is like 26psi, when I'm running 40 at the fronts haha

Thanks for the info, it's on my to-do list for sure

edit: What suspension are you running? Is it just me or does the car not have any gap between wheel and arch?

[instigator]

let me know how it went!
but remind you, it does give alot more grip from the line and if you practice a bit you will go a bit faster from 0-60 as before.
but you have to find the right pressure youreself because 1.8bar is pretty low and only good for short dragraces.
it also depends from tyre to tyre..
on a 1/4 mile i think you'll be better of with keeping it on 2.0 bar or so.
because once youre on the move, the car will go slower because the tires are flatter.
but thats for you to find out.
with my Dunlop SP sportmaxx i keep it on 2.0bar for 1/4 mile.
so my 0-60 is still pretty good, about 6.4sec, and in acceleration it will contain good speed also, i made it to 15.0XX sec
and i realy want to know youre result!

about my lowering kit,
i have adjustable suspension, KW Variant 1

From what you said, it is stock, but i saw there is something different then what I or other had in the engine bay (which pointed in red arrow) would you mind to tell me what that is? i'm pretty interesting on it by the way you did a really good job mate! i can't imagine my car could go that fast!

[instigator]

thanks for comments man!

you don't have it on your cars??? strange!!
it was stock on mine...
i don't know how it's called in english,
but i'll try and define you what it does...

i'ts a tube that is mounted on the trotlle body hose,
it will take the sound from that tube and bring it inside of the car so you have a sporty "growl" inside of the car.
it's pretty loud when you go full trotlle!
all fine and also nice to hear, BUT!
it's a useless piece of ****!
because, when i'm going to chiptune the car that thing will go away.
when i do that the car will have alot better gas response and it will accelerate a little better also.
it does that because it takes air away from your intercooler cirquit i quess? so the volume of air is now a bit more then when it's away.
can remove it now, but i'll do it when it's getting his program, i'll do it all at the same time then.
and if i have to shoose between sound or better acceleration and gas response, i'll know what i have to choose

but i find it wierd you guys don't have it in youre cars

[Bubu]

The Australian Polo GTI never got that extra piece of sound creating bit of intake.

It appears that most other countries do have it including one member on here from New Caledonia.

[kelvniii]

omg... do you have a closr up pic with that?
cuz i'm pretty interested on it and how it works~

[AusScare]

It'll be interesting to see what 0-100 you get after it's chipped.

Any idea?

[DeanB]

Doesn't the golf (Mark V or is the new VI) have something like that so that the car engine sound makes it into the "quiet" cabin ?

but then what does it called?
so i can it

[RoSonic]

you can see it in some of my pics here: http://www.vwwatercooled.org.au/newf...047#post306047

[instigator]

it's the same as in the shadow bleu GTi posted above.
and i don't know if a Golf V and VI have it...? could be.
i know how it's called in dutch, but not in english
but believe me, it's better that the useless tube stays out of any GTI...

0-60 after it's chiptuned?
my goal is 230Hp and 350nM, but the torque has got to be a clean straight line on dyno output, otherwise it will be to agressive and my 0-60 could get worse
but i'm planning to go under the 6sec with street tyres, anything in the 5.x will be fine...
and i probably manage that so my goal is to do 5.5 with semi slicks.
