    GDI

    OK. 182 is a max of 179 BHP, probably more like 175. Based on the FR7 lump the 182 engine is basically a tuned version. The 172 was tweaked and the 182 tweaked more, each time limiting the amount of power than it achievable from the engine over its base level. Yes?

    So do you think its possible for GDI to extract a further 30 bhp from the following mods?

    Piper Fast road cams

    headwork and matched manifolds

    Pro-speed exhaust

    ITG maxogen filter

    SMT6

    Larger Fuel injectors

    Power peaked at 205 bhp, at 6500 rpm and 7000 rpm


    Personally i think its bollox. proably 185-190 bhp at the most.

    So that would make my estimate of 185 to 190 about right.

    I wish they would post BEFORE rr results.

    lol.just read their post on cs....

    if the lads done it in stages, obviously as theyre building up a kit, theyve researched evry mod and rollered it b4 n after each mod. then fitted the next etc etc etc



    but the 130 at wheels figure for a std 182 seems fukkin well low to me...i know the 172s put out hugely differing figures, but most of them were well above 130 at the wheels...apart from the odd badly tuned exception.

    fukkin hell paddys was 153 @ wheels absolutely boggo

    Tuning a car with few miles on the clock like this. Good idea or bad idea?

    Should you wait until its run in?

    Weird, Monkey's williams made 137 and 131(?) at RE on two different days! I take rr figures with a pinch of salt..I think 1/4 mile is a more accurate demostrator of performance (providing you can drive off course, but even then the terminal speed gives you a good idea how quick your car is).
