Yeah, thats my polo...
in all honesty i must say i do believe my mate with the supercharged ST does not has his 295Whp..
it was tuned and dyno'd at JAM-sport, 295on the wheels and 320Hp on the engine, but i believe it's more like 200Whp and about 230Hp on the engine.
apart from that i would have no problem with an astra with 190Hp...
the day before yasterday i raced a Renault Megane RS Trophy (new model)
he had intercooler and was remapped, made 297Hp and 443Nm.
on torque i could pull away 1 carlength and stay in front of him all the way up to 235km/u,
i also tested against a Leon Cupra R wich was remapped, made 302Hp and also around 450nM.
he is exacly as fast as my polo, we go head to head all the way, only from a standstill start i am quicker, i get my power dozn better as the 6-speed shorter gearbox of the leon.
to give you a benchmark time about how fast a stage II GTI should be... BMW E46 M3 :wink:
rolling start 2nd gear i can pull half a car on him up to 180km/u, after that its equal to 200km/u, after 200 the M pulls my ass slightly.
at around 250km/u he has 1 carlength on me.
i can give you hundred of examples but it would not help you... an intercooler does :wink:

there is 1 big problem on a polo GTI, the stock intercooler is TO small and it's hidden away at the side were hardly could air can reach it.
i have a Seat sport intercooler from the Ibiza Cupra D 1.9pd 160Hp.
does the trick pretty good and it can flow 350Hp without problems.
this is what you need, trust me.
if you pull 3 times with a full stock polo, you will run slower times from the second time allready, specially on a hot day.
let alone stand if you have it remapped, more pressure = more heat, and it cant work well with hot air getting into the engine.
you can put a could air feed on it for youre airfilter etc, but it won't matter.
if you have a turbo you must make sure youre intercooler is good, that is the main key!
and you will notice you will have more HP with youre remap (on a stock car it makes nearly no diffrence, i had 7Hp with milltek and intercooler)
but with remap it will makes all the diffrence, more power and it wild hold it's power run after run (if you have a good IC system)

i can show you a video of me racing my polo with Milltek and IC against a polo with only remap, and i pull 2 cars on him in a 200m dragrace.
and my launch was worse than his so that was not my opportunity.
problem was that he had heatsoak, wich rsults in powerloss, i had 170Hp back than, he made 195Hp on dyno.
but it was a hot day, so with heatsoak he would probably have 170Hp also or even less maybe...
anyway, i wish you luck, if you need to know anyting i can help with, let me know... :wink:

good luck!

You cars a monster love it, took lukey gti out last week and he said my polo felt a lot different to his stage 1 tuned polo, soon to be stage 2! My polo seems to boost hard the the boost backs off then it boosts again at about 4500. Is there a bypass valve mod we can do on our polos too stop this think the call it th n72 bypass?

it's the N249 valve you need...

it's the black plastic "box" on top of youre engine.
it's plugged in electronicly and it has a vacuum hose that is going to the intake manifold and one that goes to youre diverter valve.
on youre intake manifold there are 2 vacuum hoses, the left one is from the N249, remove that hose by disconnecting it.
also disconnect it on the diverter valve.
take a new piece of hose +-30cm or so.
and connect it stright from youre intake manifold to youre diverter valve, but leave the N249 plugged in otherwise you will get a fault code and youre engine light will light up.

you can remove it completly by using diodes etc, or you can let it be written out of the software by youre tuner :wink:
i suggest leaving it in for a while, test if that is the problem.
normally you should have slightly better gas response and youre diverter valve will blow slightly harder.

the N112 vave can also be removed if you're N249 valve is not active anymore. :wink:

but i have to say, at wich rpm does youre boost backs off?
does the boost come back afterwards or is it more like, boost, backs off, stays there..?
normally it starts boosting hard at around 2500rpm, and at around 4500-5000rpm it starts to back off.
my polo boosts 1.5bar at 2500rpm, but it backs off the 1bar at 5000rpm and there it stays stable.
that is normal with stock turbo.
but if it backs off and it boosts again afterwards there is something wrong.
try it with the N249 bypass and see what it does :wink:

right il do that tonight and see if i can feel a difference, also have you blanked off your secondary air intake does this give any gains? it boosts hard then backs off abit then boosts again at 4000 till about 5500. really need to get a boost gauge.

hmm strange... is it noticeable or is it pretty mild?
wich mods does youre car have exacly?
exhaust, remap? do you have a 4bar FPR or bigger injectors?
because if it is remapped pretty strong it could be youre injectors are at their max, so you would at least need a 4bar FPR,
or injectors wich would be a better option but more expensive...
i also needed somthing to get more fuell, i did it with an FPR for now, works fine also.
because if i diddn't change it my GTI would not get above 220Hp with injectors at 100% (wich is also pretty bad, best not to go above 80%)
after i put in the 4bar FPR i immediantly reached 240Hp.

PS: i diddn't blank off the secondary airintake, i only removed the N249 and N112 :wink:

I had endless boost surging problems all because of a fault n75 valve!

Something to bare in mind maybe?

Which are you using?

feels abit like hitting a powerband in a cammed car it boosts then dies off abit then boosts again, im going to do that bypass mod tomorrow, what sorta boost should i be running on a stage 2? oh and im using my standard dump valve atm as i didnt get on with my splitter valve. ive just ordered the 008 so hopefully i should notice faster spooling up times. anyone running a 008?

N75 is also an option ineed.
mine is still stock, no problems so far with it.

about the boost, that depends on who mapped it and if it's mapped to the limit or kept safe...
mine is running peak 1.5-1.6bar@around 3000rpm (pretty hig i know, mapped to the max :twisted: )
but it builds off around 4500rpm and at 6000rpm i still have 1bar boost left, wich is not so bad for a K03s.

Hi, as a matter of interest, what is your mpg? When I ran Revo stage 2 mine was 20mpg.

Best wishes Justin

if it was meant for me... i do about 10L/100km normal driving with randomly a full throtlle blast.
when i drive easy without using power like a crazed animal i can get it to 4.8L/100km on the computer, but i think it's not correct and it will be more like 7L or so.
wich is still verry good :P

ps: don't know how to explain in mpg's etc... :oops:

Well that sound normal for stage 2. Got my car like 3 days ago after the software remap with Revo 2 and its about the same amount of fuel usage with that driving style!
