How much horsepower does it take to run a 100 amp alternator?
How much horsepower does it take to run a 100 amp alternator?
about 4 HP
An alternator takes about 1 HP for every 25 Amps of power. At full output, a 100 Amp alternator will need about 4 HP.
Does alternator increase horsepower?
Most alternators do not operate at full output for very long. “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.”
What is the rated output of a 100A alternator?
For instance, a 100A alternator has a “rated” output of 100A, which means that it is capable of providing 100A when the alternator shaft is rotating at 6,000 RPM.
What does the rating on an alternator mean?
The first is the alternator output rating, which is the amount of current that a unit is capable of producing at a specific rotational speed. For instance, a 100A alternator has a “rated” output of 100A, which means that it is capable of providing 100A when the alternator shaft is rotating at 6,000 RPM.
Can a high output alternator provide more amperage?
For instance, a high output alternator might be capable of putting out upwards of 300A, but it won’t actually provide more amperage than a stock 80A unit if that’s all the electrical system ever tries to draw. Do You Need a Higher Output Alternator? In most cases, alternators are replaced due to normal wear and tear.
Do you need ground cable for high amp alternator?
Since a high amp alternator will be putting out a lot more juice than the factory unit, and your power and ground cables were chosen with the OEM unit in mind, these cables might not be big enough.
Is there any free ground for high output alternators?

Welcome to PowerBastards.com your online source for high output alternators. We have thousands of hi output alternator upgrades available that may not be listed on our web site.
Which is the best charge wire for a high output alternator?
High-output alternators (greater than 100 amp) need a minimum of an 8-or-larger gauge charge wire to reduce resistance. The bottom wire is AWG 12, the middle is AWG 10, and the largest is AWG 6. The largest is always better (although clunky in appearance) for minimal resistance for alternators putting out more than 100 amps.
Can a GM 10si be used as an alternator?
This Quality Power alternator can be used as a high output replacement for stock alternators or generators or as a simple 1 wire hookup on street rods. This is the same as the early GM 10SI and 12SI internally regulated alternator but built to provide higher output at idle.
Can a GM high output alternator be replaced?
Early GM High Output Alternator (internal voltage regulator) This is the most popular high output replacement alternator. This Quality Power alternator can be used as a high output replacement for stock alternators or generators or as a simple 1 wire hookup on street rods.
