[QUOTE="superpsd, post: 1014146, member: 15821"] Well several diesel setups have been done this way. There was even an article about supercharging diesels and the blower feeding the turbo has been told the best way to go. The reasons are positive displacement blowers do not really like to be fed pressurized air. The rotors can flex but this is usually not until higher pressure ratios. The second is as the pressure increases on the outlet of the blower it takes more and more hp to turn the blower "parasitic drag" this drag reduces the gain and fuel economy. If the turbo is after the blower the discharge side of the blower the pressure will of course be lower freeing up hp and economy. If the blower is a restriction in the higher range which I doubt will happen there are options. A bypass valve is one, spinning the blower faster is two and a better option is to upgrade to a larger displacement blower to increase cfm at lower blower speeds keeping air temps in check. [/QUOTE]
