Not sure I'm putting this in the right area but if you want a fun project that will help your street and strip performance and knowledge of air flow here's a fun little Winter project. Bruce at PTS Flowbench Forum - Login sells the plans to get you going. I built the 8 motor bench so it will handle more than I will ever need. These benches once calibrated are almost unbelievable in how accurate they stay. I never totally finished mine and prettied it up but its going strong with zero maintenance after 100's of flow tests. Here are a few pictures of my build but if you are really interested sign up on the above forum and do some reading.
