    All air that is compressed is heated anyway.
    The design Its bloody simple yet fiendishly clever.

    Will the Roarer.
    I will add a bit more later.
    Ivan Rhodes stayed at our place when he came to NZ when I was about 18. His family restored it. He was a bit of a toff.

    The 'Roarer' project seems to have been well publicised as there is a lot of info still available on it. Haven't the vintage boys resurrected and run it? I thought I saw somewhere that they had, but I may be getting confused with the AJS 'Porcupine'.

    A toff on a bike? - really old boy, a "toff"? what an absolutely preposterous thing to say!

    Does that not make it less effective for producing power?

    Not really that oddball or unusual, but I love hit and miss engines.
    Just finished helping a fella rebuild an old International 10hp hit and miss engine, and now I want to have a go at building one of these.

    Yes but as I said, As air is compressed it is heated anyway,That's what intercoolers are for.

    I must have missed that bit.
    But maybe it was in dutch/swiss/german.

    Team obsolete Rob Ianuncci did the Porc, I think Sammy Miller might have one too although it might have just been the V4 AJS
    There is video of the Roarer at the Goodwood festival when Sheene raced their.
    Classic bike and racer ran quite a bit on the Roarer and fund raised for it.
    Ivan Rhodes is a major Velocette Guru from may back.
    I guess the toff but was a observation on English the class era he was brought up in, he was a nice guy.
    From memory he was a engineer who earned his living making ultrasonic cleaners for jewellery and cutlery.

    Anyway here is a Roarer Stuff from Classic racer most would have come from the stuff I linked earlier.

    What would have made you think Ivan is a toff would have been the collar and tie....
    He's a very nice guy and very approachable. i was disappointed in the Roarer when it was out here - sounded just like a bloody Triumph twin...
    The blown V4 AJS though - smallblock Chevy on straight pipes....very nice.
    If I ever run into Paul McLauchlan again i must ask if there's any info in the public domain on the weird 2 stroke he was developing for Mace engineering in ChCh. i was one of the few to see it I think. Mace saw how much money Ricky Main had made floating his engine company and Paul turned up at the right time...Money ran out I think.
    Edit - Kickaha has posted the Paul McLauchlan motor as Pivotal engine. I'd never seen the finished internet bumf production which was done to interest investors but obviously failed to gather in enough money...

    nah I think it was because he wanted to watch Coronation Street rather than Eastenders

    Now this is a different looking engine.

    a 1702 CI X-24 made out of metal stampings.

    Taylor Engines, Inc., Oakland, California submitted a proposal on May12th 1942 to build such an engine to the Navy. It was suggested he build one bank for testing and he did. The contract was never issued but it was the forerunner of what became the 44 CI Crosley CoBra fabricated engine that was contracted by the government for WW-2 and after.

    More pictures and details on the Crosley Club web site.

    Looks like it might have been a bit easier to service than the big radials of the day!

    Guzzi v8

    This (to me ) was the ultimate beauty!

    https://www.youtube.com/watch?v=W0I0ivaMHN4
    Other You tube videos there too.

    They used a couple of different crank layouts, some sounded like the Aussie V8 cars and some didn't sound quite as good!

    What an engine!!...true testament to old school engineering that one

    Honda cg series ie CG110 CG125 etc...
    Not that odd, more quirky way of saving a few dollars, plenty of others used one cam lobe such as the Indian Scout etc.
    but not so modern.......
