  1. 95 Dodge V10, 140,000 miles. Only problem it's had is rusty brake lines. I've towed a 30' enclosed trailer with two cars, small war wagon, and a mountain of wheels and tires in it all over the midwest and down to Georgia for a couple of years. Next season more of the same plus a trip to Chicago and Wisconsin. Only downfall is the 7.5mpg it gets but it does get it at 70mph.
  2. Spent all weekend there and never spotted you guys.

     

    Putnam is one of my favorite tracks. It's pretty simple and easy to find a fast line quickly, but finding that extra 3 tenths of a second is a challenge there.

     

    Took a quick look at your video and I see a possible two seconds you're leaving on the table. Turn 1, like Max mentioned, your turn in is too early. You should be braking till and just slightly into the turn in point. If you touch the curbing anywhere before the last 4 feet of it, you turned in too early. and you should be on the throttle well before the inside tire clips the apex. After the apex you should be carrying enough speed that the car is dancing all the way to the edge of the track before turn 2. Turn 4, this is the tough one to master. You should be entering midtrack, straddling the crown. As you turn in the car will step out, it's a matter of countersteering and full throttle that gets you through. Your line is the safer yet slower one. Each lap you should enter another foot or so away from the inside curbing. You will find the optimal entry point one lap before you spin off into the grass (not recommended untill you step up to HPDE 3 or 4). Turn 8 (Dead Bear), Try staying mid track untill you can see the inside curbing, then turn in and clip the last 3-4 foot of the curbing. Your exit was perfect but you'll be able to carry much more speed through it if you apex much latter.

     

    Hope to see you guys at Mid Ohio in April.

  3. Steve, you're not dead? And you're doing and engine swap? Coolness.

     

    The geometry is in both the elevation and angle of the pinion gear and transmission output shaft/ engine crankshaft. It's the placement of these items that determines how long the driveshaft will live and how many ponies it will rob.

     

    Ideally you want the driveshaft to angle downwards from the output shaft around 2 degrees and angle back up to the pinion the exact same. RX7s are a pain in the ass to make this happen properly but in most other cars it's very simple. Bust out the protractor and dust off what you learned in trig class that you thought you would never use and make some diagrams.

  4. Clever design.

     

    I can see a large market for these. When at the track the car goes on stands after every session or race. Adjustable stands are not needed and a non adjustable stand would be more user friendly. And to be able to place the stand at the point of the jack is fucking brilliant. I can't tell you how many crushed rocker panels I've seen from people jacking next to the factory lift point so they could place a jack stand next to the jack.
