    Increase GT3 MK1 HP?

    Besides intake and extuast, any other way to increase the hp of a mk1.

    How much hp and how high rpm the MK1 engine can upgrade to?
    Original is about 7800rpm, what about after modifications?

    On paper it has 360hp, what about on wheel? Around 330hp?


    Re: Increase GT3 MK1 HP?

    MK1 never really made even its spec of 360hp at the flywheel (less than 300hp at wheel). The Mk2 made more than its spec of 381hp (at flywheel)...

    Re: Increase GT3 MK1 HP?

    oh...that's unusual for Porsche! on paper Porsche said the mk1 has 360hp at flywheel??!! only under 300hp at wheel.......?

    So the mk2 must be much faster? maybe 350hp at wheel?

    Re: Increase GT3 MK1 HP?

    here stated the mk1 has around 330hp?

    i heard that all GT3s transmission loss is about 15%, so the mk1 is around 306hp at wheel.

    Re: Increase GT3 MK1 HP?

    There are extensive modifications available from respectable tuners like Manthey, RS-Tuning & some others. The modifications include expensive materials therefore it is more expensive to do than upgrade the ECU on a turbocharged engine.

    Those companines, amongst some others, are also involved in Porsche racing activities, e.g. preparing the engines for Cup racers. So they know what they are talking about.

    Greetings!

    The normal GT3 MK1 have 350-354 PS at the flywheel.
    I have PSI 3.8 litre motor with 450 PS
    First I put the Cargraphic exhoust system (complete) with RS ECU and than it have 364 PS. After that I do the engine conversion to 3.8 litre with Cargraphic exhoust and it have 410 PS (lost about 20 PS with that exhoust), after that I put the heads from GT3 MK2 and PSI exhoust and than dyno showed 450 PS.

    This would only be true if it was really 360hp at flywheel, but it makes less than that (so under 300hp at wheels)

    Mk2 should make 324hp at wheels (85% of 381hp), but it makes a bit more...

    Re: Increase GT3 MK1 HP?

    Not only the Mk1 GT3s were lacking horsepower, the first 996 Carreras did just the same. Porsche seemed to have some difficulties to put out engines with adequate numbers in high volumes.
