Posted - Jul 02 2007 : 10:53:54 AM As far a I know, no one actually produces them. My original "Strawberry" concept was not very good as well since it provided a very turbulent transition and basically dumped air right where the secondary throttle plates would go.
If you are going to make a Strawberry, make sure to provide a smooth transition between the smaller tube size and larger throttle body. You can use a commercial conical reducer fitting, or roll your own with sheet metal and a roller.
