[Land-speed] Plenum volume discussion

[DougOdom]

Years ago we were doing some R & D with intakes on the dyno. We made 
them out of fiberglass to check out some ideas and a quick way to change 
things. We drilled a 1 inch hole and put in a rubber plug in a couple of 
places in the manifold. After you clean up the pieces from one that has 
had a back fire you like the idea of only having to find 2 rubber 
plugs.     Doug Odom in big ditch
