      The straight cut gears would have played a hell of a tune.

      There's some amazing pictures around from the 1800's, incredible detail over long distances.

          • chamberlain 8
            two stroke

            I got man flu so I read a bit of a book on the light car club of Victoria.
            I Found out about a few old race tracks that I had never even heard of (one very local) and about the chamberlain 8:
            during such an early period of automotive development in Australia! These ground-breaking features included:
            A four-cylinder supercharged two stroke engine with stepped bores, vertically opposed eight pistons and two crankshafts, one of which runs through the skirts of the top pistons;
            An engine which runs up to 8000 rpm;
            Twin Ignition with two plugs per cylinder, producing 64,000 sparks per minute (from eight coils) at 8000 engine rpm;
            Front-wheel drive with inboard brakes;
            Four-wheel independent suspension;
            A space frame of small diameter tubes, much of it triangulated;
            An 1100 cubic centimetre 85+ bhp motor;
            The entire car was built in Australia

              • Despite the recent faux pas from VW and their motors, they still have some bloody good engine builders. Fat torque curve from 1600-4000rpm, that would be nice to drive.

                  Wonder if Honda will ever produce this type of motor for a dirtbike? Seems like it would be good in the agricultural sector, and Honda would make good money if the platform is as flexible as the article states. I don't know enough about motors to spot the truth in this, but the theory sounds good.

                  Make some money Honda, then throw this motor in a enduro bike! KTM might be a little nervous about this..

                              little engines needing Expensive Dexos 1 gen 2 oils (GM version) good explanation here.

                              https://www.motor.com/magazine-summa...-pre-ignition/
                              I was informed that that Dexos oil just reduce the chance of pinging, soft or to do with too much oil passing into the chamber can set it off. mainly due to thin oils that are used nowadays.
                              I recommend to drive a engine hard as you can right from new so as to try and bed the rings in as best as you can, that way you can reduce them from using so much oil.
                              But if you plod around from new then more likely to use more oil.
                              Then again some piston design will always use more oil than another, just with Petrol engines like Holden Eco tec all use oil and the Alloytec V6 is a bastard for using oil that I have seen many that do, you need only look at the tail pipes to see the build up of carbon is huge.
                              My wife has a Auroin and it uses no oil once it went 18.000km without a oil change and never used a drop of oil and I am the only one who does servicing on it and the tail pipes are clean as you can wipe your finger inside and it comes out clean, I had a 2003 WK 5.7L used nothing as well and my car I have now is the same and all were flogged hard from new.

                              Pussy footing a new engine is the worst thing that you can do.

                              If they use less oil I am sure that the problems will not appear with having to use the Dexos, but what I have come across is that most Colorado's use a lot of oil.
                              I think that using the Dexos helps save oil consumption as well as my brother says that his new Colorado has used nothing much yet, but then again old mate had 2 Colorado's that he says he nearly blew up, as he found no oil was on the dip stick.

                              • i dont believe an engine can actually use "no oil" some fuel gets past the rings and gives the impression of no oil use. just the same as some oil gets into the combustion chamber every time the piston goes up and down.

                                same as when people think their valve lash gear doesnt wear out, its just that the valve seat wears out at the same rate as the valvetrain.
