    Default CX problems ...... or not ??

    Hi Guys,

    I cleaned and polished the rocker cover on my CX ........ (big deal).....

    Now the confusing bit, I thought the car was running extremelly well....
    Until yesterday after putting the rocker cover back on ....

    The car is simply hammering now ... I don't understand why, from 2500rpm
    onwards your just pinned back in the seat as the tacho does a suicidal dive
    for the redline .... It used to have MUCH less grunt below 3000rpm ... It's
    a bloody weapon, a license losing weapon now.

    I took it down for father to drive "I don't think it's overboosting, can you
    take it for a drive and let me know if you think it's ok".....

    The old mans back 10minutes later .... My mother is yelling at him "You have
    had two glasses of wine, why are you driving " ........ With a huge smile he
    says "Don't worry, no way in hell would a cop have ever caught me, I was
    going wwwwaaaaaaaaaayyyyyyyyyy to fast LOL"... I remember why I loved that CX so much, it's top end is just incredible.

    Ok, Dads verified it, this is how the car should have always run .... So why
    has polishing it's rocker cover made a difference. I'm thinking one of the
    lines down to the wastegate was obsturcted or twisted ????? This was
    preventing the 1st stage of the duel stage wastgate opening. Anyone else
    have any ideas ?? I want to know what was wrong so I can fix it in the
    future if it happens again ...

    seeya,

    I used to take the hubcaps off and paint the wheels black on a Morris Major I had back in 1964 and I swear it used to go faster!!

    Default cx revitalisation

    It must have been the dreaded bad contacts under the software upgrade port.

    Shane I think for a more definitive answer, you need to ask Neil. I'm interested to know the answer aswell. My CX turbo feels as strong as an OX at the bottom end of the rev range, but yours really does sound impressive!

    I'm far from knowledgable on CXs, but maybe fritz has a point - perhaps it affected something electrical? Rust, corrosion and crud in general are always a source of voltage drops. Then again it was only the rocker cover...

    Hi Guys,

    Smiffy, yeah I've seen Neils reply, the first thing I checked for was lines off to the wastegate (there not).... I think this is how the car was running when my father owned it ...

    As for electrical items and plumbing, I've had it all apart in my search for why the car wasn't running properly. I fixed a LOT of things, but obviously missed something .... somewhere.

    What we should do is try to get as many CX GTi Turbos as possible together at Dubbo next year and go for a spin in each others cars. I think mine can finally now be used as a reference point as how they should all run. The reason my father bought this car in the UK is it went so incredibly well ... He actually purchased it over a later Turbo II model.

    Eg: I had a couple of people turn up at Maleny wanting to drive my CX as they thought there's wasn't running properly ........ Only mine wasn't either

    Then we have Archrivals car, it's previous owner didn't think it was anywhere near as fast as a modern fowlcan, infact not much faster than his HDi C5 ... This has me wondering does his also have the same issue mine had Archvival seems quite impressed with it's power so maybe it is ok The trouble is none of us have a benchmark performance wise

    If we could get 10 of them together at the next Cit-in that would be a nice broad range that should give us an idea exactly what performance should be lilke.

    Must be the improved airflow over the now more aerodynamicly polished rocker cover. Perhaps that is what they mean by porting and polishing

    Didn't you know polishing things has the same effect at Brocky's Energy Polariser? All those molecules are now in perfect xenolurgic alignment.

    When it starts running fuzzy again, time to polish the rocker cover again!!

    When you have to take the rocker cover off a CX25, don't you have to dissassemble the intake manifold along with all the tubes and pipes that go with it?

    Perhaps in taking this off and putting it back on you have sealed it better or reattached a tube better or unblocked something without really realising it wasn't as it should have been in the first place.

    I know its absolutely frying you mind from a theoretical sense but rather than try to make it bad again, perhaps it would be better to try to instrument how it is going now so that you can pick up what is out of sorts if it goes off the boil in the future sometime.

    Is the amount of boost in the lower rev range the same now as it was before?

    In terms of dosumenting its performance, perhaps an acceleration time from say 20km/hr to 80km/hr in second gear or something similar in third might be able to be used as a benchmark.

    Just my worth

    Actually that's not a bad idea ... 2nd gear from 20 - 80 .... 80 might be above the rev limiter cutout but I get the idea. From coating throttle just flooring it .... that way the turbo spooling up will be taken into account as well.

    Who's brave enough to sit in the passenger seat and use the stopwatch

    I'd love to bring my car to the cit-in, but it's a bit more than I can afford just now!!!
    I'd also be brave enough to sit in the passenger seat, but distance is a bit of an issue until april next year....john s

    Hey Shane, I'd volunteer for that job...only then , after experiencing that performance I'd have to go out hunting for a turbo myself.
    I can't afford to buy one right now.

    A CX Turbo and a standard CX can't be compared ..... You need to compare apples with apples.

    At the same time my father was driving the turbo I had a CX2500 5spd and CX2200 4spd on the road....... The CX2400 is nice 'n' soft, rolly polly, I always thought it went *very well*....

    After driving the turbo ... How do I put it, the standard CX is a rolly polly 'sedate' old girl ( I like it ). The simple answer of course is you need one of both. The performance simply isn't comparable (not even to the CX 2500 GTi)...

    I don't know how Citroen did it back in the mid 80's but they made a very fast turbo charged car ...... With little if any turbo lag, and excellent drivability.... Even road tests comparing things like Saab Turbo and Renault 25 V6 Turbo's can't help but comment on how much better the Citroen is than the "On or offf" turbo's fitted (particually to the Renault 25, it was marginally faster, but was a sh!t of a thing to drive off boost).

    There no speed machine though, a lot of the family cars out here are nearly as quick as it (then again we have some incredibly bloody grunty family car with 175kw of power as standard).
