I was looking on ebay for some parts for my 90 CX and i came by an electric supercharger. The idea sounded a bit sketchy to me so I tried to do some reasearch but drew a blank. Does anyone know about these? Woould it completely wreck my sohc engine? I heard superchargers work better with sohc, is this true?

 

It's a rip off.

 

Forced induction be it Turbo or Supercharger have pros and cons on SOHC, DOHC, I4, I6, V6, V8 etc. The electric supercharger will give you a bit of increase in power but for the money it isn't worth it. They are not really that great. Essentially they are a boat blower motor that pushes a little more air into the intake so you get my 1-2 PSI.

In all I would not waste my money.

 

Electric superchargers tend to fall in to two categories...
1. The commonly hawked scam made up of a glorified hair dryer on the intake.

2. A real supercharger powered by an electric motor instead of belt driven off the crank. It really works but requires two additional full size car batteries and is drained after maybe a dozen runs with diminishing performance after six runs. Nice idea, but a bit impractical for the money involved
