I think Cletus Mcfarland (youtube guy) made close to 100hp when he used twin electric superchargers in his last video. I don't watch his stuff, but (like everyone) im really fascinated with the possibilities of electric forced induction. Unfortunately there is one company making them, & I believe they failed to reach their target funding on kickstarter. Also, I don't believe they are available to even purchase. Considering the price of them as well (not cheap), id much rather pay a bit more & go superchargered.

My issue though with nitrous & the electric superchargers is 1 tuning, & 2 I hate charging/refilling stuff.

They started releasing road bikes with electronic gear shift, which honestly I will never understand. Why the hell would I ride a road bike with a battery I have to recharge so that it can shift for me?... lol

EDIT: I just want to add the ESS unit is $6000.
