    Mercedes V8 Inlet Manifolds

    Possibilities: 1) Patent portfolio contributes substantially to their investor relations, it's just patent-as-product. 2) They don't know it doesn't work. And they don't know it does. They're happy to let someone else fund that experimentation. 3) They know the patent wouldn't be enforceable for...

    Mercedes V8 Inlet Manifolds

    No worries. I found my last job pretty eye opening regarding the reality of tech innovation vs IP protection, totally different to the preconceptions I had which, in hindsight, were heavily skewed by patent lawyer marketing. Happy to discuss how/if what minimal insights I have to the tech...

    Mercedes V8 Inlet Manifolds

    Please don't take this as criticism, I certainly have no idea of the ins and outs of your project (obviously), financing, production capability nor market analysis. It's pretty obvious to me that everyone in the local "photonics/optical physics/future tech" world (a part of which was my...

    W140 600SEL

    I think a substantial number of the S600s still active are finding themselves straightpiped by brats half my age to earn instagram/tiktok clicks by "trolling supercar meets with an old merc sedan that sounds like a Pagani Zonda, lol, rofl, skibidi, etc." At least that's the answer Google seems...

    Auto Brunch Event - St Ives

    Some extremely nice cars there (although I had a good laugh at the XF Falcon hobnobbing with the *objectively* nice/valuable cars... guess my ute deserves such an outing now...). I was especially moved^ by the Meteor Gray Porsche 911 (I think its a 964 but I dunno air-cooled 911 series that...

    Ohhh ouch. $300 less than what I paid and leaking or not at least it runs and doesn't need months of faffing with aftermarket suspension just to get it off its guts and in the shed. Someone got a bargain!

    Another red 6. This time a W116 though. I'd be tempted if I didn't already have the Disco Panzer. Looks like a lot less work and I've a soft spot for carbies...

    Transmissons move on

    Sean you'd love the musical chairs they play with dual cab utes: many are made in Thailand, and the general consensus seems to be that 2 or more marques share each chassis: the Amarok and Ranger are the same car with different panels and engine options and iirc the Nissan Navara is related, the...

    C107's C107

    Oh man, the ossified window tints trigger such PTSD for me... Every car I've pulled tint off has had the layer separation, even a 2007 golf I did in 2022ish. But by far the worst was the hatch on my RX7: as if lying on my back in the boot to work overhead wasn't bad enough, Mazda applied a...

    Disco Panzer

    Went to visit Team Global Express today. Picked up a nicely wrapped present from a wrecker in Victoria. Nothing special [sighs forlornly at the M117 ECE that might have been], but maybe I can make it something useful...

    Disco Panzer

    365g/min = 487cc/min assuming a middle-of-the-rd specific gravity of fuel of 0.75g/cc. If anyone has measured a D-Jet (ideally 117.983) fuel injector's flow rate I'd love to know if it really was within 10% of 490cc/min. If so that'd be fantastic news as 500-700cc injectors are by far the most...

    Wrong vin? Surely it has to match what's on the firewall, no?

    M117 450 - 370bhp

    In fact, pausing the relevant shot: Can be taken as an indication of a 6200-6400rpm redline and 2.2-2.3kg/cm^2 target boost pressure, since they've clocked the gauges for "what you want to see" being needle-at-12-o'clock when the car is vibrating too much to read the scale. Of course that...

    It'll be in the mb data plate on the radiator support (or wherever 123s have it), but as a coded manufacture datablock, right? Don't expect grays to have a clue about that (though nsw geays generally have the common sense to at least photograph the plate)

    M117 450 - 370bhp

    Well that video provides the answer to Dr. Bill's question... the gauge to the left of the tacho is a boost gauge. [Edit, for clarity given what I said later] It isn't. It's an oil pressure gauge. I didn't realise how low the m116/7 oil pressure spec was until I did more engine research. Turns...

    Reviving this thread for a red beauty (as far as grays cars go. Running and minimal obvious flaws is a rare gem from them): https://www.grays.com/lot/0001-20086106/classic-cars/1981-mercedes-benz-280-e-automatic-sedan?redirect=0

    560sec ece

    Fwiw in an engineering sense I think a dowel pin is better than a woodruff key. The key will always bear the load on two edges in the rectangular slot, and an edge and a point in the secant slot, so stress concentration is guaranteed as soon as the vlamping force of The Big Fat Nut isn't enough...

    AMG Part Numbers for W116 and production timelines etc.

    Mine are OZ manufactured also, so I took his comment to be more about branding. Much conflicting info on the net (part of the reason I think a "this comes from AMG" info thread might help) but what I've concluded about pentas is that yes, as you say, UK manufacture early on, but also RH (from my...
