    I read that a Ko3S as in our Gtis and a Ko4-001 is bugger all difference. more lag, questionably a bit more top end.

    OK I'll bite.....

    Here is the dyno results for 3 polos at a dyno day last weekend.

    Anthony Clelland(Polo GTI) - 149.6hp (K03)
    Kenny Greig(Polo GTI) - 167.5HP (K04)
    Shane Bromage(Polo GTI) - 169.3HP (K03)

    So there you have it - bugger all difference, in fact the K03 is more powerful.

    Happy Petrina??

    But it's not so simple........ You need to compare apples to apples.

    The 2 apples are Anthony's car and mine. In fact Anthony's car has a Forge tip and other engine hoses which mine doesn't. Anthony's car has from what I understand the "vanilla" flavour Custom Code map, which is equivalent to any of the other "one size fits all" maps you get from the other chip suppliers.
    So the K04 provides my car with an extra 18bhp, which is exactly in the range of 10-20bhp that is often quoted for this turbo.

    Now the question is why does Shane's car have an extra 20bhp over Anthony's one. Well this car has 2 relevant differences. A light weight flywheel and a "custom" custom code mapping. Gavin and Jimmy have put a lot of time and effort into tweaking the map to match Shane's engine. I think it is fair to say that some of the parameters would be too close to the edge to be seen as possible or prudent in the "one size fits all" maps you get from the other suppliers.

    So with these 2 changes applied to my K04 car I think you would see the difference restored.

    As to feeling the difference Anthony has driven Shane's car and I'm sure that he will confirm you can feel 20bhp difference.

    I would love to know exactly how much of the 20bhp is obtained from the lwfw. This just might of highlighted a bolt on component which offers a decent power gain.

    Anyway, congrats to Shane, Jimmy, Gavin and Custom Code. This must be one of the most powerful K03 Polo's around.

    Jimmy, Gavin if I have stated things that are wrong or misleading about your product please correct me. I can assure you it wasn't intentional.

    Kenny

    Not sure if Im happy yet..

    did they have exhausts, dump pipe FMIC..

    Is your car just Ko4 and nothing else?

    Your Ko4 equates to about 126rwkw... Ive heard of a few cars doing mid 135's (ko3s)

    They all have the same mods apart from where stated.

    Seat intake, Panel Filter, Dump pipe, FMIC.

    You can't take dyno figures out of context. The cars with mid 135's would probably equate to Anthony's car on that dyno on that day.

    A blufin chipped Golf got this: Steve Wheeler (Golf GTI) - 174.4HP.

    Look in the clubs, meets and Events for Brisbane for the full story. Someone was complaining of "losing" 30+ bhp on this dyno.
