I have headers (of course) and was thinking I could install one of these directly into the factory ducting:
http://www.my12voltstore.com/12_Volt_Ducte...p/sd12-4000.htm I still have my booster fan, nice flappers, J tubes and plenty of ducting... they make a 50 amp model as well. It would need to be located in the engine bay in my opinion... |

A 40amp draw is huge and 8000 BTU is not much when heating a cold car.
We're talking clothes dryer draw (in amps) and the average dryer puts out 22,000+BTU |

A 40amp draw is huge and 8000 BTU is not much when heating a cold car. We're talking clothes dryer draw (in amps) and the average dryer puts out 22,000+BTU Yea, but the clothes dryer is running a 240V. The car is only running 12V. There is a big difference in the available power between 240V and 12V. A 12V car battery will only get a dryer's heater elements slightly warm. Here is the math for it: A 12V heater at 40amps is generating 480 watts. 480 Watts converts to 1638 BTU. The dryer you list above, at 22,000 BTU is pulling 6447 Watts. That works out to 27 amps at 240 Volts. ===================== The ignition system on a 914 will only draw a few amps. It is when you start running lights and wipers to deal with the rain/snow/night that you will exceed the output of the alternator. |
