Dart had one on thier site when I was looking at Wes's thread I came across it. I can't find it again. They had the story and picture and all. [QUOTE] Disagree. You make a change, flow it that will affect a decision one way or the other on design. Seeing results is EVERYthing.[/QUOTE] I said that. As a means to see where you were and where you went, they work. As long as it's same bench same heads. I'm talking from a blank sheet of paper, no flow bench wet or dry works. Wet does have the advantage of helping modify design, which dry doesn't. Wet flow shows what happens, dry is more of a hack and guess method. In the absence of money and technology, dry flow may be all shops can afford, hence its popularity, doesn't make it better. [QUOTE]Cant cook casserole in one either[/QUOTE] Right. [QUOTE]Where are you getting this stuff?[/quote] I make it up as I go along......Joking. With all the new technology and its inherent inaccuracy I think antiquated is an apt description and the extent to which it measures is a useless metric when it comes to design. The dry flow bench is best used by a porter, like yourself, to measure their results. Past that, doesn't say anything about how a head will perform. Again, given their inaccuracies and single metric information. |
