    We used to play with the stuff all the time as kids.

    It happened a few times. Most of the time when it happened to someone rather than tell any of the lot boys I just swept it down a storm drain before anyone knew what happened. Once one of the kids saw it. He got all excited and wanted to call for HazMat. I told him if he touched the phone or told a sole I'd F'n break his legs. There is just no way you can pick that stuff up. A thousand little tiny ball bearings going hundreds of directions.

    Statute of limitations is long over.


    It's not the only thing Al Gore would have me in irons for.



    One of the others is a great story but I need to tell it over a Margarita or 3 sometime.

    Hi -sorry for late response.
    Yes it's my "baby" -started off as a need for sorting 6 x DCOE's on my own 400, and developed slowly into a proper tool. The development thread here at F-Chat is already linked to in earlier post, thanks for nice comments.
    I still have a few units available on-hand for immediate shipping and pricing is still same as quoted and on website.

    As for future cool tools I have lots of brilliant ideas and concepts. First in the pipeline is a "stealth" tool combining airflow and lambda value, as well as a non intrusive "Exhaust Gas Temp" tool -although progress is slow due to dayjob and other activities absorbing too much time.

    Thanks
    Harald

    Well that Uni-Syn is a little better than a toy propeller for measuring airflow.

    I went back to the STE SK:

    Set idle at 800 rpm got all barrels to flow evenly at 4kg, fine tuned using air corrector screws for barrel to barrel.

    at about 1100 rpm, slight lifting of throttle plates, in the video you can see its flowing at 7kg, all barrels flowing dead even.

    then, after some experimenting, it seemed the third best place was 2k rpm when it was flowing at 10.5. Any more increase in throttle and the different in flow rate was not measurable. Even though I had all barrels flowing even at 7kg, there was still some adjustment required at 10.5kg.

    I suppose this is good enough, but comments welcome. I forget where the 308 was, I seem to recall you could get it above 3k rpm and get very accurate readings.

    Let me know what you think.

    BTW, the small pop you hear after revving - after hooking up the vacuum retard on the distributor, I am getting that small pop on decel, cant tell if its a lean overrun or its a backfire. It never did this when the vacuum retard was disconnected. Any thoughts here are welcome. The vacuum is taken below the throttle plates, so as soon as the plates lift the vacuum is broken, and when you let off the throttle the retard kicks back in.

    PS timing set with vacuum retard disconnected.
