Thoughts on cog setup?

[INJCTED]

I'm getting sick of my 10 rib setup slipping. I'm thinking of going to a cog setup. What are your thoughts of switching to cog. I'm running 12 psi and maybe going to 15-17 psi this winter on E-85.

Thanks

I ran one , I loved the sound
I had no belt issues with my 10 rib set up but with the cog the belt would walk off the crank pulley ..

Cool as far a pulley sizing is it almost the same size as the cog. I know cog goes by tooth.

I'm not shure about sizing , I got my set up from 98 camaro on here , he will know

i dont have any belt walk but i did it by spacing out the bracket with 1 degree of angle. BTW...cogs stress crank ends so make sure you have a crank support.

What do I use for a crank support

i would do some searching on supports. I made mine....i went through atfspeed for the bearing and mandrel and made the rest.

Why and how does a cog setup create more stress on the crank compared to a 10 rib setup?

you have ZERO belt slip... off boost will "shock" the crank end. i have personally seen two keyways snapped off with cog setups. ATI made a super pulley to attach to blower http://www.atiracing.com/superpulley/index.htm to help stop it. I have one on my car as well....when you have huge money into a motor..snapping a crank end isnt really an option for me.

No I agree nobody want to snap their crank. Thanks for the website.
