I needed a new alternator for the Turbo 1.7 car and with all of the upgrades I've done I thought I'd look around for a higher amperage unit to install. I know this has been done before, but I wanted something that was a more natural fit. And while I was looking, something with 'modern' technology would be nice.
I found a unit that looked promising and took the leap. It's a built to order, made in the USA unit. It features a built in regulator for a single wire installation, and it's 150 amps (also available in 240 amp! (IMG:style_emoticons/default/ohmy.gif) ). It finally arrived last week and holding it roughly in place nothing jumped out as a major problem, but there were a few tweaks to the housing. So a little trimming of the two mounting points, a bushing to reduce the pivot shaft diameter to 8mm, and drilling the top mount to 8mm it fits perfectly. Works just like an original unit, has MORE clearance than a stock unit although it weighs quite a bit more. (IMG:style_emoticons/default/wink.gif) I want to get this installed in my car before I make any promises, but this is looking like a REALLY easy upgrade. NO MORE VOLTAGE REGULATOR!!!

Just a caution on the heat output claims many of the Internet resellers make. Watts and BTUs are directly convertible units. One watt = 3.41 BTUs. A heater that draws 50 amps at 12 volts CANNOT produce than 2047 BTUs - not the 10,000 BTUs claimed by DCThermal.
That being said, as I stated in my post earlier, 2047 BTUs of heat generation will probably siffice for those of us that live in moderate climates. It would do little to warm a 914 in Minnesota but neither did the standard heat exchangers. Darryl |

I guess the big deal is can you get enough heat to defrost the windshield of needed. |
