    MK1 Vitesse

    in Engine

    Posted

    I have the same setup in my MK1 Vitesse,a slightly tuned 2.5 on that manifold,also modified inside for better flow.Short Dashpots.

    If yours is swing axle shafts you need to be careful,mine ate a driveshaft on the RBRR in Cornwall,snapped at the hub end,being overtaken by your own back wheel isn`t great.

    Clutch not disengaging?

    There are also different length carriers,the brass one is the same as i had on the Vitesse,i had to change to a steel saloon one when i replaced the clutch with a paddle type plate as it was not disengaging and giving big clutch slip when booted.

    Saloon flywheel is thicker than the GT6/Vitesse one hence the shorter carrier.And they weigh as much as a small moon.

    Also i experimented with Vitesse 1600 and saloon slaves to get different travel.

    Need to know what components you have otherwise it`s all guesswork.

    So it`s a 2.5 engine with a GT6 box,so which engine backplate,flywheel and clutch was fitted?.

    I have a 2.5 Vitesse but i used a saloon gearbox, Vitesse  backplate and flywheel.

    Clutch geometry took ages to get right and included chopping the slave operating rod to different lengths to get right.

    Yours looks like it`s too far forward and not disengaging.

    3,89 Differential for Herald 13/60

    in Drivetrain

    Posted

    I`ve had a 3:63 in my 13/60 FH 1300 engined Herald for 9 years now,including a single rail o/d box.I think i changed the prop as the o/d required it anyway (shorter).Always found it fine to drive with easier cruising at 70 no problem,the only thing it won`t do is go up a decent hill in o/d top.Did the RBRR in it no issues.

    About to put a new 1500 in though for more fun..+Cv conversion.

    150bhp engine in a GT6 mk3

    in Engine

    I have a Vitesse but could offer some of my experiences with running gear...

    Engine spec is 2.5 (PI Originally) with ported and flowed head,Jag valve springs,only running 2 x HS6`s but with worked on manifold.TR5 cam,fully balanced,blueprinted oil pump etc.Compression 10:1 ,Mike the pipe 6-3-1 into custom made single box system by Simpson race exhausts.

    I went for the Saloon box with J type OD which as Clive said went in fairly easily.I have a 3:27 diff with a different carrier(TR7?).I did away with the cable speedo and went electronic along with the rev counter.

    The car made 172bhp on a rolling road after running in and it is a joy to drive with tons of low down grunt and great acceleration with a top speed i haven`t come near to as its scary in convertible Vitesse.
    The only part of the running gear i managed to break was a driveshaft but mine were MK 1,i have now gone the Nick Jones CV route.

    Timing chain replacement

    in Engine

    Quoted from efp

    The only accurate way is with a piston stop and timing disk, though it’s possible to get close with a dial gauge to establish the start of the period and the point at which it starts to fall and halving it.


    This is what i did when i installed a TLD cam in a 2.5 some years ago.Valve timing was 105 degrees ATDC from memory.
    Must have been pretty close as it went like a train.
