Well, the supercharger is on the car... it's on the belt drive, and the bypass assembly is done. Runs GREAT! Looks like the lil m45 was enough to wake up a 190e after all! The power delivery is Very smooth, it feels basically like a much happier naturally aspirated engine. It doesn't deliver quite as much increase in power up above 5000 rpm, but the diufference from 1800-4000 is really noticable, the m103 was kinda anemic down low, now it feels like it's got an extra liter under that cylinder head below 3500rpm. I'm quite pleased with the setup, and if anybody's interested I'd be happy to share some info with you and post some pictures or something. Total cost of the project to date was about $400-430: $220 for the m45 shipped off ebay, $30 for the air filter assembly, About $50 in gas welding wire, and a couple tools, $50 worth of steel, $30 for a belt, a free toyota tercel throttle body turned into a bypass valve, and a few bucks for misc. stuff like gas to drive around buying parts. Best $400 I ever spent.
