JRMichler, thanks! im glad to know finally that the map is usable in vacuum. i forget 5psia IS vacuum here ha! even after calculating the pressure ratios earlier it just didnt sink in, thanks
well then i have some numbers to run, its interesting you mentioned the exhaust side of things, in Maximum Boost by corky bell he goes onto say that the compressor A/R ratio isnt as important as the exhaust. im looking at what most people put on big blocks and small blocks, seems like more than one person recommends a 1.15-1.3 for a v8, according to mr bell 1.15 is the "best compromise" for quick spool up and max power. its so neat how the exhaust flow energy is converted via turbine & compressor into intake flow energy. its just like a thumb on a water hose spraying a wheel for the exhaust, while the intake compressor "slings" the mass flow through an orifice ring around the compressor wheel, nearly at the speed of sound at times! i can just imagine the venturi effect taking place compared to a typical carb!
aardvarcus, i have REAL respect for just about anything dangerous, especially hydrocarbons. i have researched various substances to understand their properties. i have also looked into a few various vapor carbs and other ICE science. in my earlier posts i do mention possibilities of the intake charge igniting in the intake. smoky says a turbo charger will behave as a flame arrester, i have a feeling water injection being sprayed into the intake stream can also work as a flame arrester. take a look back at the videos of marcellos vapor carbs, he has an opaque nut that flickers in his intake path due to the hot vapor lighting in the intake. i am knowingly designing this with explicit emphasis on the quality of my welding and theres a real possibility something could go wrong. nothing after the turbo where the real heat is added will be made with flexible tubing, im buying premium materials and using the best available techniques to make a custom fuel and exhaust system. ill lay out my latest sketches later, and im building it very close to smokys exact design with only a few differences, i want vapors to rise, and water injection, and ill have a full sized cooling system. otherwise it should look the same as his diagrams.
ill post back when i have some good pics, peace
