Bump, @ConnClark what happened with the synchronous rectifier?

I see some driver ICs out there that make it pretty easy to build, but does anyone know of any synchronous bridge rectifiers you can just straight up buy ready to go?

I'm thinking, add 10% more efficiency to the alternator, you get an extra volt or so to play with at idle, so a 10% underdriven crank pulley (maybe just machine the original a little) can be used to slow the water pump a tad (0.9^3 is 0.729, 27% less power!) and the average savings should be something like 200W crank power saved at cruise between the alternator and water pump, which is a solid gain for a reasonable cost vs. buying overdrive alternator pulley, underdrive main pulley, etc. or electric pumps and such.
