Default Those things draw 50 amps apiece.

Depending on how you wire them in, you could loose power to your coils, injectors, or ECU when they flip on at WOT.

If I were going to put them on, I'd put a HUGE Cap in the supply line to prevent the system voltage from dropping faster than the battery can bring it back up

I like that...'just' a supercharger. You will 'only' have 155% of the hp you had before.

Default Jacobs Electronics makes some cool **** for that purpose - active 'step up' voltage regulator...

...I'm a line conditioner freak with my home audio/computer stuff, so it'd be cool to have one for the car. IIRC, these things cost a freaking arm and a leg. Cool nontheless.<ul><li><a href="http://www.jacobselectronics.com/products/caraudio/caraudio.htm">Jacob Electronics Accuvolt</a></li></ul>

Default But the ERam's only boost 1 psi,

that's well within the range of your stock fuel maps.

I'm still not convinced they'd even work, but the theory is sound enough
