Looks good. I am getting 7 hg also with 2 motors, all zones open and full table covered with bleeder value opened a little. My machine doesn't run very much, but it was one heck of an upgrade. I built the conventional box design and blocked the other two holes so I can add 2 more motors down the road. But My thinking is once I burn these two up, I should have made enough money from it to upgrade to the Hurricane made by blackboxvac.com

My motors havent got over 120 degrees yet. But I havent run them for more than 15 minutes at a time, and its not summer yet.

Wish I had messed around with vac hold down years ago.
