    Timing Retarding @ high RPM

    Holley dual sync. Hall effect. With a Holley hyperspark box. As per instructions from Holley "It is not supposed to fluctuate from the programed static timing at high rpm". If so add to the inductive delay. I've added a hole bunch to the inductive delay with no change. Like I said in original...

    Alternator whistle sound

    Alright guys now I'm just getting frustrated. Lol. Took the car to a meet tonight. Weird the longer I drive the car the less voltage the alt puts out. Come to a stop and 11.7 volts at idle...... That's the same as my garbage originally alt. It actually charges less then my original.

    Alternator whistle sound

    I think you guys are right and this alternator is garbage. Just took the car for a long rip on a hot day. The volt guage was only showing 11.8 volts at idle. And get to a max of 12.8 driving. Ugghhhh supp to be a 130amp alt. My stock one did better.

    Alternator whistle sound

    It's pretty damn tight It reminds me of the sound we would get back in the day when you would have an amp and a stereo and you could hear the rpm noise coming out of the speakers from the amplifier Sounds almost like a supercharger
