Thanks for the replies. I figured from the posts here that I have read that the Needswings were the best available at this point. I just think there are some unnecessary comprimises with all the aftermarket setups right now. Few cars have the option of easilly going out the back for fresh air like we do, so I don't know if that possibility has really been looked into. I'm really just trying to see if anyone can find a flaw in my reasoning, potential design problems or other factors that may prevent this from being a better alternative to what is available now. Does anyone know the engine travel allowed from the mounts? I know I will have to take that into consideration with my design. BTW, what are the actual gains from stock with a dual needswings intake alone?
