The trouble with this super-spiffy eRam Electric Supercharger is... it doesn't work.

Dynamometer Runs conducted on 07 February 2004 - Base vs. Electric Supercharger Comparison

I did a set of dyno runs back about 8 years ago, and this pile of junk was tested, as delivered and hooked up per instructions. While the eRam did in fact deliver increased output levels over baseline, the increases ( +0.42 HP and +1.78 ft-lbf of torque) are so small as to be meaningless.

The Thomas Knight electric supercharger is an example of just how much power is required to make real levels of boost. This shiny bilge fan that eRam sells does not deliver. The supposed gains on the eRam website can be attributed to removing restrictions present on the factory induction system.
