Any one have any Ideas about this idea. How much current would 5 IRF4905 P FETs in parallel handle, each is rated at 74 amps? My thought is to use them as a starter solenoid, in parallel with the starter motor solenoid which doesn't always work. I would tie all the gates together and feed them with an N FET rated for about 5 amps or so, with it's gate tied to the start terminal of the key. All mounted on a hefty piece of aluminum for a heat sink and a powerful schottky diode for protection.
