This is a picture of the air induction engine cover.Â Obviously some bondo and metal beating remain in the future.Â The air cleaner element sits on an aluminium plate attached to the carb which also carrys a duct back to the original Corvair engine cooling air plenum.Â The two step engine cover will have air seals to the air cleaner plate allowing it to float with the engine.
This is an overall view of the entire exhaust system.Â It is oriented the way it will go into the car.Â Exhaust outlets are located just in front of the rear wheels.Â Given the car's tight quarters, the only practical way to run the exhuast was forward.
Here is another view of the exhaust system.Â Because of the space constraints, I choose to build my own muffler.Â The collectors are actually part of the muffler assembly.Â I didn't have room for a round collector, and had to arrange the piping in a flat configuration.Â I'm hoping that this doesn't cost too much performance.Â The cross sectional area of the collector exit is carried all the way through the muffler.Â The gas path is from the collector to the muffler center where left and right exhaust flows are combined.Â The path is split and carried back to the two exit points.Â All gas path bends are generous radii.Â The outer walls of the gas path radii are sheet steel, the inside radii and all straight walls are perforated sheet.Â The flow path looks effective, but it remains to be seen if any actual muffling occurs.
A rear view of the air induction engine cover.Â Down inside the plenum the inlet opening of the duct up to the air cleaner can be seen.Â The original Corvair holes from the plenum to the engine compartment have been plated over, so the air pressure in the plenum will be available to the carb.
Another shot of the exhaust system. This is my first attempt to build either headers or a muffler. Its been fun, and the results seem to be reasonable. The muffler is only 2-1/8" thick. The extended hanger mounts are in case I need to add a heat shield in the future. To all of the guys who have been protesting the lack of factory headers for their particular projects I'll say don't be afraid... After all, if you can get factory headers, it just means that you are doing something ordinary. :soapbox:
