Bob. Thanks for the pics. That does give some other ideas for carb placement options and the linkage required to make them work.
Special thanks to all that sent the extra Teapot carbs and related parts so that some additional carbs could be put together for the tests. I have installed some of the new ‘orange’ accelerator pump cups from Daytona Carb Parts and those are definitely an improvement over the older black cups that have been coming in the Teapot carb kits. Finally have some Teapots shooting fuel like they should.
The testing is scheduled to start on the morning of Monday, January 14th. If all goes well, then three days of testing is expected to make a large dent in the amount of testing planned. If it takes a fourth day, then so be it. Picking out the pairs of carbs to be used for a majority of the testing could prove to be cumbersome depending upon jetting, linkages, and who knows what else.
The first round of tests will be with the ported 113 heads on the engine and then they get changed out to a set of aluminum heads for the real workout. While the ported iron heads will likely give a good idea on how the different manifolds compare to each other, the thought process here is to force any restriction issues the intakes have by freeing up the head flows even more by using the aluminum heads. When I did my first round of carb tests on the dyno mule back in day one, I had used the older style Hedman two tube headers and the lack of response to carb changes and ignition timing was in a large part due to the restriction taking place in the exhaust. The EMC project made big strides in the exhaust area so I feel confident that this will be a very definitive intake manifold test.
