A high performance filter will accomplish the same goals and still provide protection from the elements. I ran a lot of open carbs in my day thinking I was making HP, and sucking in who knows what into to those motors. I got old and wiser. Well I got old and computers and dynos made me wiser....[/QUOTE
I'm sure the Doctor knows best. I used to run velocity stacks on my bikes for a time. I never thought I was getting less grunt. It's nice to have dynos around to find these things out. I was probably sacrificing some low end torque with my straight pipes too. Sounded faster. May be the same deal with the green foam.
I don't know best, just a lot experience with trying to makes things faster. I run shorties on my Harley Fatboy, and lose a lot of top end. But, it's a Harley, if I want top end, I need to go back to crotch rocket. I learned a long time ago, the filter manufacturers were actually looking out for us, and they do protect the engine without taking away performance. That had to proven to me. I was stubborn to give up the open concept. Now, a diesel is another story about wanting plenty of air...with the turbo. But again, I run a good proven filters in the rig as well. Like a stated, you can build something close to a Needwings product, but I saw his and Woody's dyno numbers and the trial and error of that build. That convinced me to pony up the $$$$$ and run the best.
