Larger / Lighter Alternator Pulley

[smckeown 1]

Ryan mentioned this ages ago, and i've done some recent research. It seems running a larger pulley does provide minor power increases. And a lighter one has a similar but much reduced effect as fitting a lighter flywheel.

 

Has anyone fitted a larger pulley before ? or know why supplies them ? If anyone knows the size I could contact brise that i believe supply various pulleys.

 

I'd like to try and find a smaller alternator in a scrappy before paying for a lighter one from brise

 

cheers

any of the jap cars have very good and in some cases small alternators with good outputs.

i'm using one from a toyota carina 60amp.

you will of course have to do a bit of fabrication.

I know Forge have done some lightened and over-driven pulleys in the past, I could ask them about it as I have a spare alternator I can pull apart for them...

don't know how much it weight's but it's pretty small,

i think there a photo on my photobucket.

if you want i can get the O/D for you.

I recon you could make the pulley from a PAS pump fit into the alternator. It probably onlt needs the centre drilling out to fit.
