MECHMAN Posted April 28, 2009 Report Share Posted April 28, 2009 Every so often we get high output alternators from other alternator companies sent in for repair or testing. We have a policy of not dragging other alternator manufacturers names through the mud, but I will tell you that all of the units shown in this thread are from well known alternator manufacturers that regularly sell to the car audio market. We have been trying to get people to understand the difference in performance that can only be achieved by converting to a large case housing, so perhaps this will tell the story a little better... This unit was sent in to us because the customer thought that it was not working and needed repair. We put it on the dyno, and as it turns out there was nothing wrong with it. The customer thought that it wasn't working, because the output was so low at low RPMS, that the voltage wouldn't come up above battery voltage below about 1200 engine RPM. This unit came off of a 1997 Toyota Celica, and cost the customer $380 + shipping. The output curve is almost totally uselless for any vehicle driven on the street. It produced zero amps at actual idle speed on the Celica, and only 25 amps at about 800 rpm. Even at max. RPM, it barely produced 154 amps cold. It was built with a used rectifier, used brush holder, (about 75% life left) and used stock rotor. Here's another unit from another well known high output alternator company. It cost the customer over $600 + shipping and took 3 weeks to arrive!!! It is based on a large case Denso design, and was also built using primarily reclaimed parts, stock rotor, etc... It did OK at idle, about 125 amps by 2500 RPM alternator speed. This is comperable idle output for our 200 amp ProPower large case kit. Peak output was at 244 amps, it was sold to the customer at a 280 amp unit!! The unit above came off of a late model Jeep. Our 250 amp Rhino series unit for the same vehicle outperformed the Denso at ALL rpms, and is $100 less expensive. Our 250 amp Rhino series units usually dyno out around 270 amps with over 150 amps at idle Quote 1-888-MECHMAN www.Mechman.com [email protected] Link to comment Share on other sites More sharing options...
