High power alternator options...

So I emailed a company called mechman and while I don't have anything to do with the company I figured it was some good info and pricing.

Those vehicles have a pretty low idle speed, and a relatively small crank pulley, so I generally recommend either the 170 amp or the 240 amp S series unit if you want really good output below 800 engine RPM.* The 320 amp unit starts making good output at about 800 rpm engine speed and above.* (if you require a lot of power, but also want good output at idle, there are power programmers available to increase the idle speed of the vehicle to 800 rpm if necessary)* All three S series units are pretty much indestructible, even in hot climates. All the S series units feature our twin heavy duty internal rectifiers, oversize charge post, billet aluminum overdrive pulley, cutting edge 6 phase hairpin stator technology, and 12 massive diodes.* 6 phase technology allows for outstanding low RPM output, in a moderately sized housing that bolts right in to the stock location.* All S series units are made in the USA and come with a 2 year warranty.


Here’s a link explaining what makes these vehicles so awesome:**




170 amp

300 rpm turn on

500 rpm* - 120 amps

800 rpm* - 150 amp

1200 rpm – 170 amps



240 amp

500 rpm turn on

650 rpm - 100 amps

800 rpm - 140 amps

1500 rpm - 240 amps



320 amp

600 rpm turn on

700 rpm - 100 amps

850 rpm - 140 amps

1800 rpm - 320 amps
