ok doing a 10 rib flip drive mock up for my car right now. my question is for you guys already running it is regaurding the alternator. with flip drive old ac pulley (which is smaller)runs power steering pump as well as the alt so turns them slower. not to worried about power steering but as soon we finish my motor work we are starting a high end jl audio system. so i am thinking i should look into getting a alt pulley made to spin my it faster to compensate for the flip drive spinning accessories slower. here couple pics of my mock up for kicks lol

and yes belt changes are gonna SUCK!!!!!!!!!!!!!!!!!!!!!!!

It turns as fast as it does in stock form... You get an overdrive alt pulley from several places.

yes the crank spins the same speed. but the front pulley that runs the accessories in stock form is 7.48". while the rear ac pulley that runs the a/c is 7.16". so with the flip drive the power steering pump and the alt are running slower because they are ran off the 7.16" rear a/c pulley.
prob is most guys running flip are racers so will never think about throwing a high end stereo in the car lol... i on the other hand want it all...gps, ac, heated seats, monitors, dvd, big power, bass, top storage, comfort ect lol
so my guess is most are not having issues because even guys running slp underdrive pulleys not having issues and that is 25% underdriven. this is less then 10%. but the underdrive pullies warn agianst large stereos lol....
