  1. Theres enough notice to pick up some cheap air-fair... would still be fun to play spectator.
  2. I pass through Portland regularly. PM me.
  3. Thanks Guy's. I'll try to stay on top of it... let me know if I fall behind

  5. The 3rd definition appears to be the most accurate... 3. teh: An expression used by idiots to helpfully identify themselves to other idiots.
  6. I looked up "teh" in the dictionary... its not in there.
  7. RTz

    Brilliant!

    I'm seeing shadow...
  8. Alan, I guess I read Jon a little differently. No doubt, knowing where you've come from has value... only a fool would dismiss history. However, It would probably be just as foolish to think we haven't learned anything since. I believe that's what Jon is getting at.
  9. Sort of. They go to a relay, and the relay feeds the ignition module.
  10. Joel is correct. You've got 24hrs to edit posts. If you need something edited, PM an admin.
  11. This switch is also used to switch pick-ups on dual pick-up dizzy's.
  12. ...and now we return to our regularly scheduled programming...
  13. You are, you just don't know it yet The length of the runner is all about frequency tuning. The length determines the timing of the returning pulse. Longer puts the return at a lower RPM, at the expense of high RPM restriction (function of CFM though a given size). 6" from face of head to inlet of runner (including the velocity stack). Keep in mind, my prototype was built for a show car first and foremost. The difference in performance between a 6" runner and a 7" runner would be minor in this case, but the effect on appearance, with this particular manifold, would be pretty dramatic. A compromise was made at 6". Otherwise, I think a 7" runner would have been a better choice. Also, in retrospect, I believe the 1.5" runner was a little oversize for the cam we settled on. A 1.4-ish runner would have bolstered the bottom-end with no loss on the top (and quite possibly would have shown a gain). Its commonly taught (and mirrors my experience) that runner diameter is the single largest influence on where the torque peek falls. Runner length, in normal scenario's, seems to have more impact on the area under the curve. In other words, how flat or peaky the curve is. Keep in mind manifold design is both art and science, and a person could invest an entire career in manifold design. Its not always black & white... and the 'intuitive choice' doesn't always prove so.
  14. 720 crank degrees divided by 6 cylinders = 120. So... intake duration would have to be 120 degrees or less to avoid 'overlap'.
