ok now a turbo has the compressor and the....thingy attached to the exhaust headers. they are connected by a shaft to the two thingys that spin to compress the air. now instead of having two housings why not have one separated by a wall. that would keep size and mass down and since mass would be less it would spool faster. ok now someone throw a stone into my idea so that i can see whats wrong with it or if they already make it. <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/biggrin.gif" border="0" valign="absmiddle" alt='
