Can anyone give me a place to start for 6 rib Belt size on my combo below:

Procharger Bracket, Flip Drive, 4.25 blower pulley, and 8.10 OD balancer. The back 4 rib part of the Od balancer is Stock diameter so i'd assume I would just use the suggested belt that matt said there 490 K4.

I can try to measure with an old belt by wrapping it around and then once its tight cut and measure it but i figured I'd see if anyone was running this combo first.

Thanks!

As for the blower side, when I had a 6 rib belt, that belt number was a napa belt. Part number 060525. That was with a vortech t trim blower with a 3.125 blower pulley and a stock diameter ATI balancer.

Thanks I'll start there.

49 4 rib
37 6 rib as stated above. Not sure on the blower, I use a 53 with Andy's bracket.

Dayco makes a 060365 that you can cross reference to other brands and that might work better for you if you truly have a flip drive. They're a little harder to get on, but often work better with their tensioner.

That top belt length won't work for you for sure since you have a procharger. You need to pull the tensioners and lay a belt over the charger and balancer and mark the length and then work from there. If I had to guess, you'll end up with a 55-56" belt.

Wrap a string around the pullies that will get you in the ballpark then buy a few above maybe even below. I bought like 400 bux worth of belts then kept the one I needed and returned the rest.

Not quite the same but if it helps here is my setup and belt size. Stock balancer pulley size, A&A new bracket, A&A secondary drive, D1SC with 3.0 pulley and the belt size is perfect. K060516 (52.175").
