Heres my Two cents on the turbo idea.
Using a turbo on the Flathead in this application to run all out top speeds would not really be any better if the boost was progressive. If anything the progressive boost can create a huge problem by being lean in one RPM range and creating a rich situation in another RPM level. Running Lean is the killer when running a Flathead with a blower no matter if its a turbo or a roots type. Just going lean for a split second and the damage is done. Turning the turbo with the exhaust will create a restriction of exhaust flow thus increasing the super heating of the water taking place inside the block. This also will add to the danger of going lean. However things dont end there with the boost air pressure entering the carb inlet once the air pressure level goes above the fuel pump regulated pressure point the carb fuel bowls now filled with this air pressure will not allow the floats to drop to let the gas flow in and fill the empty bowls now you risk being lean in another way. To address this last issue the fuel pump/regulator system must be designed for the blow threw system. Going with a turbo turned by exhaust flow on a Flathead is not easy I know Phil Landry hes going in a different direction and is setting records along the way if it was easy everyone would do it. This combination is truly the best of what back yard hot rodding is all about. Now some may ask if i would try this idea and the answer is no. The supercharged class i run with the race car is a vintage class the rules do not allow the use of turbos,electric injectors or engine management systems.
