    Here's one I've yet to understand - why does a flat 4 cylinder engine (VW/Subaru) sound so distinctively different to an inline 4? Same number of cylinders and especially with the Scooby all exiting through a long single exhaust. 4 cylinders, common crank, why does the physical layout of the engine make it sound different?

    Not having my own place and garage means driving let alone fettling progress isn't slow (play those nanon violins harder) this should be rectified in the next 10 days.
    But I've managed to wash and polish it

    and fit a PAS steering wheel.

    And clean off what I thought was rust from the interior light bezel

     
    But was in fact ciggy smoke and tar build up.. 

     
    Soon I'll have a decent sized garage and workshop  so I can attend the laundry list of jobs, new (to me) perspex tinted P4 visors  new carpets and sound deadening (to replace... none)  sort the damaged window runner seals, align the windows to seal better, some welding,  new back box 🤦🏻‍♂️

    I've been driving past this imprisoned Mondeo for a fair few years now; finally stopped to take a picture yesterday afternoon.


    Mmm, yeah... that's not moved in a while.
    DVLA says the MOT ran out in 2016, which seems about right.
    Not entirely abandoned, as the house itself looks in reasonable trim, but I think this one's unlikely to see the road again.

    I would try using a dial test indicator with the wheel centre bolted to a hub. 
    Shouldn't be too difficult to rig something up to get it true

    Some of the cars made in Iran by the Sapia company.
    Like the Saipa Tiba.
    Or
    Or the Saipa 151, which the interwebs says is a Kia Pride, which in turn was a Ford.

    Then there is the Z24 Pickup.

    Website for the company.

    Went big car boot.  It was packed.  Zero social distancing efforts from our east european and traveller friends, who were in abundance and seem to have made it their own.  Nothing worth buying either.
    Went to Big Clock Tower Tesco.   This was the state of it.  Useless.

    Chucked it on, now showing no reading when cold

    a run up the bypass and to Halfords for fresh coolant saw it doing what I'd expect with no thermostat fitted

    fitted the Febi thermostat, changed the coolant as I'd lost plenty taking it apart 74 times, now runs up to 90 nicely and stays there, fan kicks in etc. Win

    Excellent explanation thank you - so in theory any 4 cyl would do it with the right exhaust design - but you wouldn't because it's not efficient.
    So with the VW/Subaru you're hearing blub-bulb...blub-blub rather than blub-blub-blub-blub if that makes sense?

    I didn't bother with the boot sale today despite fine weather, partly as I expected attendance to be down due to yesterday's downpours, partly cos we're both stressed out and knackered this week.

    However in your absence I was passing Boreham today and popped (for the first time in years) a very depleted bootsale. Chatted to the hot wheels guy, nice fella. Resisted to a point, but did  buy some NASCAR though at a £1 a pop, and I binned (the admittedly battered) boxes too 😳 😂

  21. Thanks
    bunglebus reacted to Asimo in AS mad science: understanding burble. Place for discussion and amateur science.   
    The fundamental reason is because the two front cylinders fire 360 degrees apart, as do the two rear cylinders. This  means that the two left / two right cylinders each fire 180degrees / 450 degrees apart. No other firing order is useable with a flat-4.
    As installed in the car a flat-4’s exhaust headers are usually of unequal length ( because the front cylinders are further away from the silencer than the rears) and therefore the time taken for the pressure pulse to travel to the exhaust exit is not equal for each cylinder. Hence the burble. 
    VW beetle is an extreme example of this withtheir stock exhaust system, as cheap and uneven as they could make it. However,  with a 4-1  equal-length “stinger” exhaust, there is no trace of burble.
    Subarus with a single turbo have very different path lengths as the turbo is on one side of the car, hence their extreme burble. (Possibly deliberately designed to accentuate the throb)

    Alfa did their best to rid the Sud of throb with a very good attempt at a true equal length exhaust.
