Will a high output alternator hurt my car?

That is, your alternator will only supply the amount of amperage a particular component demands—and no more. So high-output alternators will not harm your components or charging system, no matter how high you go with the amps.

What does a higher output alternator do?

A high output alternator is generally used to increase the amperage within the electrical system. When an alternator is not turning quickly, the output could be reduced hence not keeping up with the demands of a charging system.

What vehicle has the highest output alternator?

Niehoff C803D Niehoff claims their C803D is “the highest output commercial alternator available.” This unit has a cradle mount to adapt it to most commercial engine applications.

Does an alternator increase horsepower?

“On some applications, a high-amp alternator can actually add horsepower to your engine’s performance.” Sure, it’s nominal, but, when it comes to horsepower, every bit helps. “Most alternators are only about 75 percent efficient.”

Can an alternator fry a computer?

The only way amperage can damage a circuit is if the circuit is not fuse protected and a power wire grounds or shorts out. This causes the massive amount of stored battery current to travel the circuit burning everything in the path. This scenario can happen with or without the vehicle even on.

Do you need a bigger alternator for sound system?

If your sound system demands more power than your stock alternator can supply, then you will benefit by upgrading to a higher output alternator.

Does alternator increase horsepower?

Is a 220 amp alternator good?

With some extra work there are ways to get decent charge going, but even then the 220A alternator is probably enough for most scenarios if there are no other non-vehicle loads.

What is the highest amp alternator you can buy?

The highest 12 volt produced by Prestolite Leece-Neville is the J-180 mount 4890JB and Pad Mount 4962PA both of which put out 320 amps. When it comes to 24 volt alternators there is one manufacturers that really stands out – C.E. Niehoff has their 500 Amp C-803D.
