Hi, depending on how bad your voltage was before the alternator swap It can effect to tune. Ie. I had a car running down to 13.2v on full load swapping to ls alternator I had 14.2 at full load. With extra voltage across the whole map. It made the car run slightly richer than previous as noticed on the wide and when driving but didn’t do proper before alternator Dyno and after alternator swap dyno to get exact figures.

Hi Matt, I have made the pulley ratio for my kits to be about to handle 10-11k rpm As that would equate to 6-7k rpm on the ls1 motor.ls motor runs a larger diameter harmonic balancer and a smaller alternator pulley. With the RB the balancer is smaller and the pulley is larger. Also I have had cars running at idle with 3 Walbro 460s all on at idle with aircon on max,headlights lights on and maintains 14.2volts. Below is a data sheet from a generic ls1 alternator a customer sent me.

If your going to upgrade the alternator, I have always suggested you upgrade the power and earth cable to the alternator. No point doing half the job,

Ls2 and ls3 alternators are pwm controlled. So unless you have a aftermarket ecu that you can program to control alternator output the stick with ls1 as it is plug and play

My personal car runs The Mitsubishi alternator, made in Japan, OEM on all Holden ls1 engines. All others I have seen not including powermaster but they might be, are made in China. It's a personal choice but as my favourite saying goes. The poor man pays twice

When upgrading alternator I do suggest adding another power cable inline as factory system as you pointed out has a fuse 80 on Gts-t and run through a larger spade terminal at the fuses boa the gets real tired, especially in a r32 Gts-t, r32 gtr runs twin terminal to spread the load.

Sounds about right, seen voltage like that on most factory setups, FYI Ls1 alternator gets 14.5v to 14.2v all the way to redline. Bit extra voltage for you pumps, coil packs heaps a lot. And if your running A Agm battery you need 14.2 to charge it correctly. Buy the way I like that you are using ssr [emoji106]

Hi yes I can send to NZ. You can SMS me on +61417677905 or Email [email protected] Or find me on face book Andrew Cwc Hoareau To work out the shipping cost etc..

What alternator are you running? What's your voltage at peak rpm ?

CWC Ls1 kit sits right at home bolted to a Prp Billet bracket

For the power thirsty

Before and after voltage reading @1200rpm ons standard r32 gts-t

All good man, Billtech is a top bloke and good at what he does.

Mr Billtech uses my kits but I am not him even though we are both named Andrew. Does that answer your question
