This also allows the alternator to spin at its own speed when the engine is decelerating. Overruning alternator pulleys help to reduce noise, vibration, and harshness. When performing any repairs to your. The alternator pulley won't increase the speed of the supercharger it's to stop the alternator over spinning hence why it's 5% larger 2% crank pulley with the 17% pulley on the charger will be equivalent to 19% so IAT will be high, if I were you I would stick to 17% and standard size crank pulley unless you are running meth to keep on top of the temps.

What is occurring is that the alternator is not spinning out fast enough to start charging, so the light is on. Once you rev the engine, the alternator starts to charge and remains charging till its shut off and restarted. Be careful with a smaller pulley. If you spin it too fast you will loose all output from it, and be strictly relying on battery voltage at high RPM. Most alternators don't like spinning past 16,000 alternator RPM, some don't like going past about 14,000 RPM. You can do some simple math to figure out what RPM your alternator will be spinning.

How to Test and Replace an Alternator Clutch Pulley - YouTube.

Got a 1-7/8" pulley from a members here. the pulley was offset a couple ribs and the hub was too thick to use the lock washer. so i made the mystake of grinding the hub about 3/16" to get it back in alignment. then realized the reason its offset is because now it rubs the case. used a washer to get it back how it was. seems good, hopefully it wont slip due to the washer and no lock washer. now. Like the King pointed out on page 1, even though this is an over-drive pulley for the alternator (1.65" -vs- 1.90" stock), the alternator still isn't spinning as fast as the stock 1.90" pulley was spinning it with the larger crank pulley.

You have a 3 to one ratio, you multiply your engine RPM by 3 so if your engine is turning 1500 RPM's your alternator is turning 4500 RPM's. Use a pulley removal tool to remove a press-fit pulley, and a hydraulic press to install a press-fit pulley. Pressure should only be applied to the hub, never the pulley flange.
