Title: DDS power pulley belt size Post by: Fritter on July 21, 2012, 02:35:20 am I have a few DDS power pulleys with the 3 "kidney" shaped holes in them. I want to run one of these babies on my '64 but I don't know the belt size needed. Anyone know?
I assume it's a smaller size than the belt I currently have on there with my Santana power pulley. Title: Re: DDS power pulley belt size Post by: andy198712 on July 21, 2012, 17:23:49 pm What's the pulley dia?

Title: Re: DDS power pulley belt size Post by: Fritter on July 23, 2012, 18:38:07 pm Thanks for the answers, I'll check out the 9.5 x 850 with my teeny tiny Deano crank pulley. This pulley should add at least 50 horsepower according to my calculations. :D
Title: Re: DDS power pulley belt size Post by: Fritter on July 24, 2012, 15:07:03 pm Update: I don't think the 9.5x850 is the right size for the smaller Deano pulley. 9.5x850 is the size I am running now with my Santana power pulley.
I think I'll try the rope trick. ;D Title: Re: DDS power pulley belt size Post by: Cheesepanzer on July 26, 2012, 02:29:11 am ;D
Title: Re: DDS power pulley belt size Post by: Bruce on July 26, 2012, 08:29:14 am The DDS pulley needs a shorter belt than a power pulley.
I had my DDS pulley machined to make the groove wider to take a wider (stronger) belt. The belt I use is a Ford JB-331. This belt is 33&1/8" long, or about 840mm. Title: Re: DDS power pulley belt size Post by: Tobi/DFL on July 26, 2012, 08:54:20 am Hi!
The belt I used was 835mm long. Tobi |
