    HELP !
    try as I might I can't log into the new site - password reset requests go unanswered ... the only reason I'm able to post this is that my computer is better at remembering login details better than I. I'm now really worried I'll miss the opportunity to register for RBRR on Dec 1st.. What should I do.

    Engine chatter above 3000 RPM

    in Engine

    Posted

    My recommissioned MK II GT6 is bringing plenty smiles but she still doesn't sound as sweet as I remember.
    > 3000rpm there is a "chatter" from the engine.... but only under load.

    I can't replicate the noise when revving the engine stationary and it disappears no matter revs or speed if not on the throttle. It is evident when accelerating through the gears @> 3k  but most noticeable on a motorway run taking her above 70 in overdrive 4th as I gently take her beyond  our Motorway Speed Limit.

    There doesn't seem to be any loss of power and she is capable of revving higher - although the noise cautions one not too.
    The engine is 1998cc and mildly developed with a TR5 Cam and twin HS4's, Vitesse Lucas dizzy.

    I have my own ideas but would really appreciate your thoughts before leading the discussion further. Thanks

    Brake servo causing brakes to bind

    Quoted from heraldcoupe


    When you serviced the master cylinder, did you replace the main spring? Reason I ask is that I've had work hardened springs cause exactly this fault, gradually pressurising the brakes with each application of the pedal. The first time I found this the spring appeared to be physically perfect, however approximately one third of it's length had become work hardened; this section would not compress.
    It was the last thing I changed...

    Cheers,
    Bill.


    Thanks Bill - what you describe is exactly the symptoms I have - but I'm beginning to believe there are multiple reasons. Not only are the brake lines connected wrongly but if I am interpreting the diagrams in the link the one way valve is also the wrong way round.

    As my brain is now so scrambled please confirm that air should be allowed to flow towards the inlet manifold and not towards the servo!? ...it's easy to test the valve by blowing into it - but the arrow that should be on it isn't legible and the stamp that reads servo maybe printed upside down!

    OK can someone confirm that the connection of brake pipes should be as per the manual in the download above. Because if I'm interpreting the labels correctly the experienced triumph workshop that recently recommissioned my car have connected the pipes the wrong way round.

    So to be clear the feed from the brake master cylinder SHOULD: -  ENTER the servo in the SIDE of the slave cylinder and LEAVE towards the three way connector to front and rear brakes from the END - of the servo.

    Please someone confirm this and reassure me that making up new brake lines will finally solve my problem.

    BTW disconnecting the vacuum pipe from the inlet manifold at the inline non return valve and plugging with an appropriate size nut seems to have confirmed that the rest of the brake system is OK.

    I know you don't want to bypass the servo, but I'd be tempted to do so on a temporary basis just to be 100% sure the servo is causing the problem. 3 servos with the same fault strikes me as being more than usually unlucky.


    Yes I see what you mean. Does anyone know of a brake line junction box with just two ports?  - of which I'd need two if I was to construct a short bypass without the need to replace the existing brake lines?

    Although I can find several online threads on various piston head type forums referring to this - no one ever seems to come back and explain  the definitive cause or a permanent fix that works!

    I'm now on my third servo - two of which have been brand new - one cheap chinese rimmer repro the final one an expensive original from Moss. .. and the problem persists. I don't want to bypass the servo.

    It's fitted to my MKIV 1500 engined Spitfire and the servo sits in the battery box ( battery in the boot ) - The angle and mount position seem exactly the same as when every thing worked perfectly. I've serviced brake master cylinder too. Bleeding the brake line to the servo cylinder is all that is required to free the brakes. Sitting in the garage with the engine running and pumping the brakes doesn't seem to induce the problem - but a short run with say half a dozen decent brakes will cause the pedal to harden & the brakes to lock on!!

    Please help - what do I do next?

    Spitfire  & GT6  -  Rally Winners ?

    My research on this thread seems to be developing into more of a study about post competition dept rallying in France. I think I've finally unraveled the the url of the French forum - so may as well share it here for you all to scroll through - there's as much in there about TR's and sheds as Spits & GT6s :

    http://www.forum-auto.com/sport-auto/histoire-du-sport-auto/sujet378115.htm

    This is also a very useful site: it's a collective effort to realist events, entrants and results - needless to say the French have already made many entries.

    Spitfire  & GT6  -  Rally Winners ?

    Anyone ID this - with its ill fitting none standard hardtop.
    Several of the pictures are taken from a French Forum - Does anyone know if the reference is to an actual book or just a blog. Triumphs en Rallye de 1960s is going on my Amazon wish List if such a book still exists.
    The caption suggests it's a GT6 but there's no bulge - is the driver Christine Dacremont and if so what is the vehicle specification and event?
    I was searching for info about Jean-Louis Barailler - who I'm beginning to believe may have been the most successful Triumph Rally driver - if not of all time certainly of the Spitfires & GT6's. It's interesting to note our the competitive spirit of our little triumphs in Rallying didn't just die when FIA Regulations and Comp Dept attentions turned to 2000's and 2500Pi s

    This one I think is from Mugello


    As this is not  a Rally Spitfire - I thought I might do the ID and leave it for the Race Boys to cherish: No. 125 was driven by Michel Pilet (CH) & Marizio Marsini (I) in the 1967 Circuit Mugello where they came 41st in the race won by Udo Shutz in a Porsche 910

    It's an easy question - but a difficult answer.

    In trying to gather evidence to support the rallying heritage of our wee cars I've been trying to searching googles archives.

    I knew from Graham Robson's book about The Works Triumphs that Roy Fidler & John Hopwood took the 1962 built development car 412 VC to second overall in The 1964 Welsh International Rally.
    Also that year Terry Hunter & Piot Lier took ADU 7B to 2nd o/a on The Geneva Rally

    And I knew that class wins were achieved in 1964 on the Tour de France, Paris 1000km and in 1965 on the Geneva & Alpine Ralliys ....

    But surely with a name like TRIUMPH my 2009 win in Greta on the Tour of Cheshire couldn't be the only time a Spitfire or GT6 had won a rally out right! In any case a humble historic road rally isn't really in the same class as International Rallies back in the day. I was drawing a blank. BTW  - do please post here replies about other Spitfire and GT6 class or out right wins on competitive  Licensed rallying events.

    Anyway I had to find out more.

    Working on a hunch that as at least some of the works rally Spitfires had been sold in France I started to search google.fr - Bingo - vindication of what we all already know - our little cars ARE capable of winning amongst the more exulted marques.

    Jean-Louis Barailler is listed as being the outright winner in 1968 on the Ralle Petroleum-Provence in a Spitfire 1300 and in a GT6 he won The Ralle d'Antibes in both 1967 & 1969.

    * Rallye Pétrole-Provence : 1968 avec Maximilien Sibon, sur Triumph Spitfire 1300;
    Jean-Louis Barailler


    * Rallye d'Antibes: 1967 et 1969 avec Maximilien Sibon, sur Triumph GT6 (6e en 1974);

    I've not yet found alternative sources or photos so do please contribute to either verify or refute the above. As this has probably been discussed before please can someone also provide a link to any earlier discussions.
