V6 oversized pulleys.

They look decent enough, I'd prob get them anodised as raw alloy corrodes fast here. If I had something like that sitting in a box for a decade, it would be covered in white rust by now

What are you looking for them?

[vlad01]

Called up one of the better anodisers here in Melbourne, they reckon about 90 bucks to do the lot of them which is less than I expected given how much electroplating normally costs.

I'll get the alternator one done in natural and the others in black so it looks like OEM but obviously better.

Sent you a PM.

I run a larger water pump pulley and not had any issues.

I did drill a hole in the stat as its a L67 and apparently difficult to get all the air out. I found that the car ran too cold and the heater in winter was rubbish.
Slowing down the water pump mad the world of difference to the operating temp.

[immortality]

That is interesting. I've tried multiple different thermostats from different suppliers but it always does the same thing and runs a few degrees cooler than thermostat temp.

I remember years ago reading about rb’s and how they changed to a larger water pump pulley because of cavitation or something along those lines. Was a drag car obviously pulling high rpm. My take on them is there more geared towards high rpm racing applications where you want to slow the alternator down and water pump. If the water pumps spinning too fast you get cavitation and there’s not enough time for the water to effectively cool while passing through the radiator. Slowing it down in that instance helps with cooling and the cavitation issues. That’s my understanding of it all anyway. On a street car I’m not sure if it would be needed
