Great info & thanks for posting!! I looked for part #s on the pulleys used, but couldn't find any #s.
My car is not far behind their MAX with a 1.26:1 ratio
As I mentioned/posted earlier, I think the aftermarket pulleys are primarily designed for optimum performance & not best cooling. The GO FAST guys could care less about driving for miles with their AC running
Supply & demand right??

Your post is very interesting , I've got some heat problem i n trafic too . With a moroso 5'' inch on the crank and a 6 7\8 on the WP I've got a ratio of ,727 not very good at idle . I've found a 7'' crank pully but it seem to be very difficult to found a 5 5\8 WP pulley , for the part no 3418227 it's 1 7\8 deep but my 6 7\8 WP pulley is 2 7\8 deep, does a WP pulley with a 2 7\8 deep in the 5 inch range exist ??

Hi @Yves
The WP pulley I used for my application is shown in Post #155 at 2 3/4" deep. Sometimes you have to improvise with washers or spacers to get the desired result for pulley alignment.
There are SO many combinations...that's why I called this a Rubik's Cube project
Lots of work to figure out...I think you're on the right track with the larger crank pulley to overdrive your WP.

Last Tuesday I've found from a guy in my area the same pulley shown in your post #155 , to make it fit we think to shim it but in fact to make that pulley fit i will have to stretch it to 2 15\16 tall , the rubik cube don't work with this one . Today I will replace the 7'' crank pully with a 6 1\2 and a 61\2 on the WP It will be better than my first set up , 1:1 is better than ,727:1 I will try to find the tall 5 5\8'' pulley or something around for my water pump if not I will have one made next winter.Hi @Yves

Update , it's much better with the 1:1 ratio . On the road cruising a 60 temperature straight at the thermostat raiting 180 . In a parking lot idling from 180 to 210 in 7 minutes a lot better than last week at a car show i saw 230 in maybe 3-4 minutes . Next think maybe I will upgrade is to put a fan shroud
