I realize this can change...

    Interesting project to watch.....Superb craftmanship

    Here's a link to a CA engineer who is scratch building a rear engined "Lotus 7" called the Midlana.....I guess it will be a track car. Unbelievable craftsmanship. Click on the "build diary" to admire his work and wish you were as skilled. ;^) http://www.midlana.com/

    Video and data overlay software

    Who has experience with these type of products? Is it fairly straightforward to get everything all synched up in the absence of a GPS based camera or DAQ. I am aware of this product but no others. http://www.racerender.com/RR2/Features.html Here's the hardware I have...

    For those folks with HANS devices older than 5 years (like mine) no need to get a recert yet. Finally something that is logical and makes sense. http://scca.cdn.racersites.com/prod/assets/RM_11-10.pdf

    2 stroke exhaust port carbon blockage question

    Not being very familiar with 2 strokes I thought I'd ask some experts: What symptoms would I expect to see from a semi blocked exhaust port? I'd expect low power but what about idling quality, throttle pickup, need for choke or not, vacuum generation in intake manifold, starting ability...

    Making Sense of squiggly lines DAQ interpretation book

    I conned my local library here in Indy into buying a copy (wanted to see it before I buy my own). It just came in so once I get through it I'll report on the quality. The standard may still be Buddy Fey's "Data Power". It's out of print and copies trade for silly $$. Thanks, Jay
