[kypreo]

Hey guys what options do i have for alternators?

Im after more Amps.........

Thanks in advance!

I didn't fuk around.... jumped from 70A alternator to 140A to keep my Optima battery and Fuel pump happy lol.
Had to do a few extra mods to the wiring system, but in the end I'm seeing 14v at the battery in the boot and the fuel pump

How many amps is your current Alt?
How big is your current battery?
Have you upgraded the "big 3" on your electrical system?

HUH?

Standard Alternator.... 70amps??

Full River Cant remember.... Similar size to the standard battery.

Sorry for the dumb question but what is the "big three" ?

I can guess alternator, bigger or lighter battery (relocate to boot maybe ?) but can't think of anythng for a third...

I was wondering also ^ haha

I can only think of higher capacity battery and cabling?

Bigger cable, bigger fuse but dunno what other 1 is

Ya 3 main power cables isnt it

Done it myself. Plus an 8g cable from battery to 30A fused relay to my fuel pump cradle. The Walbro gets as much power to it as possible to help with increased flow demand.

The Big Three wiring upgrade
A good, cost-effective improvement is to perform the "Big Three" electrical upgrade. This will vastly improve your vehicle's electrical system, allowing more current to flow easier to all components. This upgrade replaces or augments three key cables in the electrical system with 1/0 or 4 gauge wires, the battery ground to chassis wire, the chassis to engine block wire, and the alternator plus to battery plus wire. This increases your electrical system's current flow capability, ensuring a more consistent voltage under varying demand conditions.

Got a part number or reference for that 140a alternator.. I need a new one now..

hey yes I would like to know this as well

Here is my link to the bigger 140A alternator and info: http://www.4gtuner.com/topic/10127-evo00x-evolved-awd-coupe/page-29#entry279347
Included BA BF Falcon 140A Fusible link part number in pic (<$10.00 - Buy a spare for future use).
More pics show the added extra wire (2nd wire) I used to connect the alternator to the fusible link instead of one huge massive thick cable which would have been more difficult to fit in there. Still looks factory
Guys, always check the pics ACE ALTERNATORS use in their sale and compare it to yours.
Mine is for a GVR4 6-bolt engine and I checked the structure and alternator pulley for the rib design of the alternator belt before committing to the purchase.
More pics coming...

more pics...

... and the last pics.
Remember, this is for my GVR4 4G63 2 Litre 6-bolt engine.
