Post by: 8v-of-fury on April 23, 2009, 06:30:32 pm: What about just using the 90amp (?) and running a 1.0 or 1.5 Farad Cap?

Post by: lancer1978 on April 24, 2009, 03:51:16 am: up to 2.0farads is only good for 2000wrms, and 90 amps my lights will be dimming, my previous car had 140amp alternator, 2 batteries (both were deep cycle yellow tops) and my lights would still dim. I thought since I found the 200amp for a steal of a deal price, I could mod it in somehow. 5500wrms is a lil much for daily, but I also plan on competing either this year or next. :D

but what I kinda wanted to know , can I use Mkiii alternator in a mkii car? with minimal modding? or do I gotta do a buttload of wiring?
The only reason im persistant on this, is im getting a mkiii alternator for cheaper then a junkyard would ask!!!

You can convert to serpentine but by the time you buy the parts to do that you might be better off getting a mk2 alt re-worked to put out more current.

Thank you very much, this is Exactley what wanted to know.

Post by: truckinwagen on April 28, 2009, 06:16:39 pm: a 200 amp alt will take about 3.2 HP to turn at full load(assuming 100% efficiency of course)

so i'd say about 5kw which is about 6.7hp. so that alternator will require nearly 50% of the engines idling power... and don't forget about any other accessories running.

Well apparently i was told it won't work out to well for my application. I am going to inquire to Iraggi Alternator and see what he can do for me.

Post by: shegel on May 26, 2009, 06:50:55 pm: what about hooking the alt up to an ac clutch and just using an insane battery. that way you could turn the alt on once your under way and off when your idleing. maybe a microswitch on the ip?
