boosthead is feasible, but...using motors that draw 700amps... number one, your battery only puts about that much out...number two, a focus alternator is a 120 amp unit. the blower may work great but your robbing alot of hp with the alternator trying to keep up with the blower. that and how many times do you think a battery will last having that type of a suddden draw, not to mention the alternator having to suddenly recharge. personally, i wouldnt waste my time, but others may say they are great. i look at the whole system picture and whats effected. that and everything that has to be relocated to fit it, that equals more cost.
the last two are nothing but a huge ol laugh...nothing but a fan thrown in the intake. research fans a little and you will find all sorts of things wrong with the picture. for instance a phenomenon called stall. different things can cause it such as the fan pushing more air than needed, a sudden draw of air through the fan,...etc. besides, does the fan run all the time? if not its nothing but an air restriction.
the last is nothing but a squirrel cage fan. they are notoriously inefficient. they also tend to come apart durring stall. same fan, just smaller as the one in a furnace, great for blowing air through a duct system with many openings, but start closing them one by one. once its all closed the fan actually recycles the air around its blade. it was never designed for pressure type applications.
look at the dyno charts, yeah, really cool. they got a few ponies. but thats with a standalone battery, not with it hooked to the vehicles electric system...
ok, mister wizard is gone for now
lol. thats what happens when you build industrial fans for quite a few years...
If you want an electric supercharger go to your local boating supply place and buy a bilge pump and put it in your intake tube. Pretty much the same thing just dressed up and made pretty.
