    Good to know...

    Re the company ethos - an old guy I knew went to Nissan late 70's - tagged onto their sportscar race programme - and used to tell me much the same things.
    The round eyes were useful - but after they'd been useful, it was sayonara, mate...And respect the hierarchy at your peril. It probably helped he was a pretty senior bloke when he went there - he got listened to.

    All very interesting I must say!
    To us the Japanese are an enigma, but they have a good attitude towards team work and organising business. However they do seem to pay attention when in our usual slap happy disorganised (wildcard?) way, we occasionally come up with something interesting, then they will exploit it to the hilt!
    That's not to say that they are not good innovators themselves, but they don't seem to scoff at other peoples' ideas either.
    Kiwis and Aussies appear to be good at figuring out and perfecting ideas they have managed to dig up and combine but unfortunately, (although being individuals and capable of individual thought) they often do not have the resources to go any further and the Asians with their expertise in team work step in to help ..... themselves! and why not? we leave it all outside on a plate, free to a good home!

    BTW I am not New Zealand born but I have lived here a lot longer than most people on this forum and I am proud to call myself a "Kiwi".
    Freedom of speech is important but if what we say is considered incorrect by our peers, they will quickly put us right.
    P.C. will eventually destroy our right to tell the truth.

    The old guy I quoted above had been at Coopers in the 60's then went to the US and did the Can-Am series in a Lola. Then went to Experimental Engine division of GM for two years...Then got asked to join the Nissan programme by the Pom running it. When I knew him he was doing rally cars out of a small shop in ChCh. AMIMechE and member of the S.A.E. too.

    His comment on Nissan in the 70's was they they couldn't innovate on their own. Their ethos was to toe the company line. The roundeyes were there to bring the designers and engineers up to speed on the current innovations - and take them forward if possible. All the overseas guys were on short term contracts.

    I used to run RCCI without even knowing it (hadn't seen the abbreviation before). With regular diesels running lambda values of well over 1, there is enough oxygen in the cylinder to burn not only the injected diesel fuel, but also a fair amount of LPG, which happens to be half the price of diesel .
    Point of attention: do not introduce the LPG until downstream of the intercooler, or you may experience the hood-removing mother of all backfires.

    its a pretty well known trick here that's been arround for years that when uprating turbo diesels you can also use a LPG as a claytons Nitros as a bonus as well as being cleaner burning it also works as an additional intercooler.

    Thanks Frits, Ive been considering adding an intercooler AND LPG boost to my Ford Transit Race Transporter. Now I know where (or Not) to place it.

    cheers, Daryl.

    Yes, he's absolutely correct and starting out as a fitter & turner I learnt that one early on in the piece - the japanese are good engineers, but seem to have omitted all this knowledge in the interest of cheaper production.

    Another thing, the British Whitworth thread is superior with it's rounded thread form but again it's probably cheaper to use the sharp corners of the present day metric thread forms! (this BTW also includes the American or unified thread form.)

    All true but the studs used did not give trouble until the Kawasaki three was modified for racing.
    What Cameron omitted to say was The engine he used was likely a modified mach 3 engine that he originally tuned and built up to racing spec.
    I believe that Japanese are masters at just doing enough for what its designed for.
    They would have likely spec'd a different stud in the real H1R.
    That said Camerons later H2 that he built in a couple of weeks was also faster than the Kawasaki fielded by Team Hansen.

    FWIW, the H2 cases to turn them into H2R cases, had several stud base areas built up with weld.
    I've got a Cycle World article here with a pic of a pile of cases with the welds visible.

    I've also seen H1 cases with stud base areas cracked out of them...

    I wouldn't mind seeing thoses pics and write ups.
    He talks about the Boston cycles racing kawasakis h1 and H2 but doesn't have a lot of pics in TDC.

    I've got the initial Cycle World articles about the H2R and the TR750. Jody Nicholas was on staff and riding for Suzuki at the time so he's written the TR article - with riding impressions in Japan. Ivan Wagar i think did the writeup for the H2R and rode it in Japan.

    The early flexy flier TR makes interesting comparison to the final one analysed by Jennings in Cycle mag some years later. I have nothing on the later air cooled H2R or the water cooled version.

    Let me know next time you're over here and I'll hunt them out - but I want them back !!!
