Pulley Diameters

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 :eek: Lots of work to figure out...

I think you're on the right track with the larger crank pulley to overdrive your WP. :thumbsup:

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.

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
