[s-cars] eRAM

[Trevor Frank]

I suspect until we are running more pressure in our electrical systems. Like the move to 48volts that will be coming in the future or even higher voltages.  Such thing are out of the reach of efficiencies that can come from there mechanical counterparts.  Although I wouldn't discount them, electrical superchargers, or ancillary systems to boost traditional supercharger/turbochargers with electrical motors, I suspect will have there day, IMHO.

I've been thinking about the idea too but the problem is that that tiny fan
can't give enough airflow for even a 1.5liter engine, never mind a 2.2 or
more. On Ebay.de there used to be loads of them, presented as TÜV-free,
well, the idea is that TÜV approval is necessary and mandatory for any
engine upgrades that exceed a certain percentage (5-7% maybe?) and as this
stuff didn't need TÜV approval, it was quite obvious that it wasn't worth
the 20HP the seller was claiming. IMO, in some cases if not any such a crap
can even restrict flow and reduce HP!
