10 rib users, Info inside

Not sure if this will help anyone. But since I've been doing some research on ten rib belts and lengths. Dayco has supplied me with this and I thought I'd share. These are for the DAYCO Poly Cog Gold 10 rib belts. Part numbers and lengths. Gates and Goodyear seem to have similiar lengths.

5100495 example this is a 10 ribbed belt that is 49.5" long
5100510 51.0" long
5100518 51.8" long
5100533 53.3" long
5100540 54.0" long
5100555 55.5" long
5100568 56.8" long
5100575 57.5" long
5100585 58.5" long
5100600 60.0" long
5100608 60.8" long
5100613 61.3" long
5100630 63.0" long
5100635 63.5" long
5100640 64.0" long
5100655 65.5" long
5100660 66.0" long
5100665 66.5" long
5100678 67.8" long
5100710 71.0" long
5100720 72.0" long
5100730 73.0" long
5100770 77.0" long
5100845 84.5" long
5100855 85.5" long

Sweet! That'll help for sure. Hey what would a ballpark length be on a 351, 8" crank, 3" blower pulley setup? Since you've been at this a while. :teeth:

Vortech sends the 5080565 with the 8 & 3" pullies. However, I used a Gates belt of 25-080595 (60"), yet I mounted my braket on my 351 motor with the 302 mounts. This put the blower more to the left and up higher. So if you use the 302 mounts I would say try the 5100585 58.5" long or the gates 25-100579 (58.5").

Also Gates ending number aren't always the size in incehs. Close but vary.
Isn't this fun!

Yup that sounds about right. I can't imagine very much belt slip with the 3"/8" 10-rib stuff but time will tell. I can't quite make the cog commitment.

You'll be fine with the t trim.

I might run the 3.33" 10 rib and 8" crank, cause i really do want bracket car like consistency. I'll bring the assortment but i doubt i'll need it. :D

this spring will be a scream. The poo will hit the air oscilator when scott finds out the smack has already begun. :D

So it is written.....













So it begins :signs:

Fix that head gasket scott? :D Gonna be hard to run us down while running out fuel. ;)

Another belt note....

Just read on LS1tech about a guy who was fed up paying $$$ for his 12 rib belts.
He decided to try 2 6rib belts instead. They worked perfectly for him.

You want to be careful though that the 2 six ribs stretch together or that you have some sort of strut support from the SC to Ccrank. What can happen not necassarily is that when the bracket flexes the belt closest to the radiator will have less tension and may fly off. Not necasarraly, but the posisbilty is there. The odds of it happening are not as great as it not but if id does and you burn the paint in the enginge bay, you'll be :mad: .


Just thought I'd put my 2 cents in....

Do you have a website to order the belts from? I tried Dayco's main site and got nowhere. Thanks.

I just use a local store. Go tyo there website www.dayco.com and click on the Parts & Service locator tab. Then enter your Zip. This should pull up the dealers in your area. Call them and tell them the part number you want. They then should hook you up!

Blownby what would you recommend for a 358" windsor car with a T trim. Looking for around 18-20psi. Do they make a 10rib setup that would get me close to this without belt slippage.Auto car with 6200-6400 max rpms. Thanks

Vortech now sells a 10 rib 8" setup. The part number is 8E021-295. This is for a 10 rib 8"crank and a 2.95 pulley. This should get you the boost your looking for. They also make the kit in a 2.85 or 2.75 SC pulley configuration. Just change the last three number in the part number accordingly. The 2.95 is as large as they make in the 10 rib kits, I believe. They may make a 3.13 but I don't think so. So if the 2.95 is to small you may have to have a custom made 3.13 from ASP. Or IAN if he ever starts back up. You can bead blast the pullies if you need more grip. But I'd say you'd be fine to start as is and see how it goes.

The 8" & 2.95 will put your blower at 58,007 RPM's at 6200

So you think the 2.95 will get me around 18psi. How much more boost is normally obtained going with the 2.75. That sounds like the kit I need.What do you mean "bead blast the pullies"? Thanks for the reply.

Let me ask you this! What size pullies and what boost are you currently making? I'm not sure what size pullies will get you that boost exactly. But these should be in the neighborhood. Maybe higher. I don't think you'll need a 2.75. You'll have to ask a T-trim user. I never ran a T. Just S and YSi.

Bead Blast. You can have the surface of the pullies shoot with glass bead. It improves the traction of the pully.

The difference between a 2.95 and 2.75 is probably going to be like 3 psi. But more issues with slippage probably. I'd say try the 2.95. Plus the t is only good to like 60,000 rpm's I think.

I just have the head unit. No pullies really except the stock stuff. Havent ran it yet bc motor is not done. I went to vortechs sight and seen the kit. I think I will try the 2.95 version. If it gets me atleast 16-17 psi with no slippage I will be happy. Trying to get this thing in the 9s with a 358".

Send a PM to regattacoupe. He is doing damn near the exact same set up. He'll give you some good insight.
