    Default New Tool For Tech

    NNJR has a new tool.

    Simplified:

    Take cylinder temperature

    Measure bore

    Measure stroke

    Attach Whistler

    Read compression ratio

    Still with analog gauges when you can get down to the hundredths place for pass/fail. I still would prefer a digital meter, that can be calibrated. However, it is still better then the current pratice.

    Note we also have tools for measuring bore and stroke without pulling the head. As I understand it, these tools were purchased, and are wholly owned, by the region using Spec Miata compliance funds. So, they get first dibs, of course. But these tools are valuable for non-destructive tech checks. Especially given our recent discussions on wanting to keep everyone honest, I suggest we use it often, if nothing else to see how it works and keep Tech on its toes.

    How about each class get together and agree to use it post-race on one random competitor each day? Everyone's name goes into a hat and a random name is pulled, and they get a full Whistler check. I'm sure Scott would be OK with this, as long as they're not incredibly busy. Absent a formal protest someone could certainly refuse the test, but that would simply draw attention to them, inviting a future protest.

    We've got it. Let's use it.

    +1. How about top 3?

    I like that idea. Would it have to be done during the 30 minute impound? If so it woudl make it a very busy 30 minutes to get to the top three in each class per run group.

    It's a good idea and I'm for it, one thing, we have mostly
    RX-7's in ITS can we do some sort of check with a rotary engine too?

    Only if you want a Steward to have the ability to bounce the car post-race.

    I'm personally thinking more inline with a self-policing "gentleman's agreement" type thing, more of a peer pressure to "encourage" competitors to show up with a clean car. If done by Tech but outside the formal 30-minute system, we have the flexibility of time and space (and I'm not worried about someone running back to their pits and hurriedly changing their compression ratio back to 1/2 point over... )

    Russ, we do need some way to check rotaries. But, unfortunately, I think we only have the finger method, and not too many objective proctologists that know what they're looking for (i.e., the guys that know are the ones that are doing the checks, so it's a moot point).
