I have a stillen upgraded kit pushing 12.5 psi (cog, impeller). The belt cog is not centered on the idler pulley (pushing more on the pulley towards back of the car not front) and it's eating up cog belts (third belt in 2 weeks). I have it tensioned properly when I install it and as soon as I start the car, the belt shift all the way to the side, and when I drive it, it starts to rub against the side of the pulley and belt goes. Any help guys would be great? such a stupid problem to have especially since the car is running mint beside that. thx you
