Alternator current anyone know this?

[NightSpirit]

I'm buying a Varley race battery as the stock one weighs in at 12kg...does anyone know what current the alternator produces? and what sort of draw the car pulls when running (no stereo/heater etc) just driving the car with a rad fan on constant, maybe wipers/lights...

This dictates what size battery I can get away with. I want to run the Red Top 8, but may have to run a 15 or 20.

Help me pwease!

if memory serves a N/a without air con, electric windows etc is a 55A

if it has full electrics its a 70A alternator

Not sure on the draw.

So the GT is going to be a minimum of 70Amp...now I only need to find the draw on that. Anyone know the Amp per hour of the stock battery?

As it stands the alternator is doing enough to run the car and charge the battery, so I'm guessing with a smaller battery the charge used to start the car should be replenished even on a Red Top 8, even if it's slow the battery won't deplete totally so if I run it on trickle charger at all times it should be fine :S

... what... lol

Sorry I'm rambling..

basically, the stock alternator is obviously creating enough amp to run the car and charge the battery...otherwise the battery would run down. So, providing the Red Top 8 has enough power to crank the car without a jumping battery (that would be gay) it should charge on a normal journey and definitely charge with the trickle charger at home...so...I think, the baby Varley will do what I need it to do on the car even though its charge capacity is 7amp.

2.7kg battery ftw
