i found this model (
Small Alternator, Mini Generator (YAF-54) ) that may get me the amps i need especially if i do 2 of them plus i could do 2 solar panels like this to trickle charge what the wind does not and they would fit into my sun roof and still allow me to use it. (
1.5 Watt 12V 90mA MINI SOLAR PANEL for CHARGING BATTERY - eBay (item 130436312637 end time Oct-03-10 20:45:07 PDT) )
i have decided to do a fan behind the radiator since being after the radiator i have nothing to lose in drag or cfm in air moving in to cool the radiator / engine. plus when the fans kick on turbo boost to compensate for them coming on
this idea is very feasible and could replace an alternator it would not be good for a vehicle with heavy electrical load ( bass systems, lots plugged into the cig lighter, lots of lights, etc.)or for alot of turning the engine on then off but for a hypermiling vehicle that neutral coasts instead of EOC this could replace the alternator with out worry of dead battery.
also side note: the solar would trickle charge the battery to keep it topped off which would help the battery last longer and reduce the amount you have to replace those expensive batteries
