    VXR Turbo Progress

    well,

    my standard turbo started kicking out plumes of smoke so with PVS very near i had to fix it quick.

    took it to midpoint garage to get a quote, and what list of new toys ill be needing.

    it was a nothing special install, vxr turbo, restrictor bolt, yada yada. i asked to have an uprated collins actuator so its something a bit nicer in the engine bay.

    handed the car to him last saturday and i knew his schedule was very tight with pvs near and every man and his dog is finishing off final tweeks.

    so, i picked it up on friday at 4pm with an aim to see it on the rollers after a remap, while i was their, happened to see a few familiar faces, Ateeur, i think he lives their now

    Ian also mentioned he didnt buy and install the collins because the vxr actuator is brand new, it wont need replacing for another 12 months, so saved a bit of cash their.

    bit of info on my current toys.
    full 3" SS exhaust from turbo with 200 cell sports cat
    large TX intercooler and large 63mm piping
    standard airbox with k&n and vec c air scoop
    sparks and other usual stuff

    before the exhaust, intercooler and turbo i hit 221 bhp with 217 torque.

    now, it hit 289.2 BHP and 378 lbft torque.

    holy c**p that torques crazy. Ian said its a high torque map and he himself was impressed with the figures and said it was all down to the exhaust.




    i asked how i should drive it with pvs here its gonna get some stick, he said drive as normal strait away just let it warm up and cool down adequatley.

    drove it home down the nice windey road to manchester, and wow, the first boot in 3rd i did, it scared me as the front of the car just kept sat up all the way. still not hit it in 1st or 2nd yet.

    very impressed and happy with their service and outcome similar to whats been echoed accross this forum.

    thats a horrid dip in engine bhp there, a z20let should be smooth and be making power untill around 5500rpm before it starts to drop off,

    makes some very high torque that, i bet the wheels spin well. lol

    What remap software you running? Like mentioned, the graph is trailing off very early.

    Uprated clutch??

    nope clutch isnt uprated, thats the next big thing on my list. but also purchasing some vxr fuel injectors at PVS.

    the software is EDS.

    could the dip be due to not enough fuel being injected, coz im running standards?

    dont know mate, but im running 304 bhp and 356lbft with eds software and i hit max torque at 3100 and max power at 5500 with no dips. currently on std fuel pump.

    you must be able to feel the dip when accelerating in the car? as you loose 50bhp all of a sudden then gain 30bhp few seconds after.

    are you running std injectors and afm?? if you are they are running at their maximum limits so any weekness could cause something like this

    Well I suppose fuel pressure might be dropping at the top end, but if the fuel pump is up to the job maybe the fuel filter is partially blocked or maybe 1 or more injectors have a distorted spray pattern??

    yeah, i do feel the dip, mainly when cruising then adding more acceleration it feels as though its prematurely dumped pressure.

    standard injectors and afm. picking up injectors at PVS, probably get the afm off same guy too, already got the 3bar MAP sensor but not installed, will just need the airbox and pipe to fit the 80mm afm.
