Cog pulleys/belt kits?
Just saw that RPM is selling a cog set up, can someone please explain to me the advantages/disadvantages of this set-up? I am still a newb when it comes to this stuff....

You asked this exact same question back in January man: "Cog belts?"
Anyways, my reply is still the same:
Cog setups are for race only applications. For street applications you want to prevent as much belt slip as possible while maintaining the ability to slip if something goes wrong (ie the boost by pass fails on a high rpm deceleration). If something goes wrong and that belt cannot slip bad things will happen.

Thanks Steele, I totally forgot about that previous post, guess I should use the "search" more often. Thanks for the explanation again. I guess thats why no one else came up with the idea, huh?!

As far as it not being a good idea for a lightning is up for debate I suppose. I'm just pointing out what could happen. If you are having a belt slip problem there are more safer/streetable ways of solving it.

I am not having any slippage issues since the idlers. I just wanted to find out if the cog set up was more efficiant or what the deal was behind it. Thanks for the info!!

I think there needs to be some belt slip on our trucks.
Just think driving around (not racing) and your truck shifts... RPM's drop about 1000 rpms. So the supercharger will snap to the lower speed. That can't be good on the bearings/rotors.
If there was no slip, it seems the belt would stretch or break. being cogged, that's not a cheap one to replace.

Just an FYI... My posts in this thread are over two years old. Although I still agree with my statements it would not stop me from buying a cog setup for 20+ psi on a Whipple if it could be found.
