  1. I dont think youll need a 'special' prop for the Vitesse cos with mainshaft TKC899 3 rail box is the same length with either D or J type OD unless of course yours didnt originally have OD in which case you just need a new standard OD prop. If you do this youll have the 3 rail OD box that was used in the early Dolomite 1850 which many people like for its stronger J type but Im afraid I would also like to have the larger mainshaft tip needle bearing design which of course, as standard, is only used in single rail. 

    Ive been looking at the possibility of a single rail into a Vitesse and apart from the bell housing mod, 1" longer length and clutch plate change I would be concerned about the gear lever position and how well the original plastic gearbox cover is going to fit.

    How about putting the single rail internals in the 3 rail but with TKC899HD modified mainshaft (for bigger tip bearing) and J type with thin adaptor? Then you only have to have a change of clutch plate.....

  2. As I understand it theyre no better than any other mechanical fans in terms of air moved but as the engine revs higher the force on the blades from moving air increases and tends to flatten them out so they move less air and consume less engine power. Effectively they move more air when rotating slowly which, as in a traffic jam, is when the engine needs more cooling cos theres less cooling effect from the movement of the vehicle. However Ive never seen any test results showing the power or fuel saving......

  3. or ask Canley how long their 131008 studs for the later Spitfires are as thats almost certainly the ones theyre confusing it with.

    In fact Ive just seen that theyre showing as out of stock for 136818 (and even more expensive than Rimmers!) so could they be giving you the longer ones instead, surely not😲

  4. yes looks like theres only one for all models except for USA models after KF10001 when theres another part number but I dont know whats different about it. Yours isnt from the States by any chance is it?

  5. I would say youve been sent the wrong part. Looking at Rimmers you seem to have 131008 for the later swing spring back axle or possibly what you would need if fitting a suspension lowering block between the diff and spring on your car. It might work but I suspect if youre not using said block you'll run out of thread before the nuts are fully done up so best go back to the supplier.....

    Exactly. I enjoy driving it - though I filled up today and have only done 100 miles since filling up in the summer last year. Must try harder!

    And it isn't about driving fast or anything like that - its simply roof off and country roads. 

    Thats disgraceful! I thought you could be stripped of your membership if you do less than a 1000 miles a year😵

  7. Ive had silver minilites on mine for years now (cant remember where I got them now) and the only problem was corrosion under the laquer appearing within months. They were part painted and part clear laquered so I sent them back and they were painted all over under warranty. Since then theyve lasted really well so I dont know why the manufacturer made them with the laquered part in the first place....

  8. try driving it on normal fuel to see if it runs without pinking (rattling sound in engine on accelerating from low revs). If ok you could just use a lead substitute additive to protect the valve seats if theyre not the hardened type and youre going to do longer, high speed driving.

    If pinking is a problem you'll need to either retard the ignition timing (losing a bit of power), use higher octane (RON) fuel or an octane booster (this last option comes in a combined lead additive).

  9. Ive been looking at Powertune remote servos on ebay recently for my Vitesse as the price keeps coming down, now 75pounds delivered. Theres a few things thats putting me off:

    location as the engine bay doesnt lend itself to fitting a servo, I think there could be increased brake pedal travel with a servo, loss of brake 'feeling' and more chance of locking the wheels up (need ABS but that would be a bigger modification!), reports of people having problems with these servos.....
