Modern Charging Power for Classic Cars
We love WOSP Alternators and Dynators, but why? The million dollar question when it comes to upgrading any part on your classic car should be: ‘If it worked well enough in 1966, why do I need to upgrade it in 2020?’
The answer, of course, is we are far more power hungry in 2020. Even in our classics we demand: Stereo, high powered headlamps, electric cooling fans, USB ports and the list goes on! When you start to tot up the additional drain from all these things it is no wonder the originals struggles to keep up!
If you have a car that was on the road before 1965 it probably has a dynamo. In peak operating conditions such as driving down a A-Road at 50 MPH your dynamo will produce about 13.5 Volts at 20 AMPS. As soon as you slow down, that drops back and if you sit idling, the battery will actually go into discharge.
In modern driving dynamos are rarely charging your battery. In fact, if you have electrical add-ons such as an electric cooling fan, they are only just keeping up with the basic demand. Lead acid batteries like to be kept really well charged. The more time they are in discharge, the more performance they loose. It does not take long for them to fail, however big the capacity.
The answer of course is to upgrade your dynamo to an alternator. They produces more power, more efficiently. They even charges your battery at idle. Yet thanks to WOS Performance, an electrical engineering firm in Aylesbury, Buckinghamshire there is an even better solution.
