So over winter i decided to piece together an 8 rib kit for my vortech charged 2v because the 6 rib seemed to only really hold for the initial 10 -20 pulls then slowly starts slipping worse and worse along with blowing belt dust. Now my car makes about 17 psi at 6500 mind you i only usually run it up to 6k (just a weekend toy not racing) so maybe 14 - 15 psi. So i thought forsure an 8 rib would do the trick and unfortunately the signs are already appearing of the dreaded belt slip. Im currently using a brand new this spring dayco tensioner with about 1/4-1/2 " of play left on tension. Also my car is an 04 with the single bolt tensioner i have heard the timing cover withe the 3 belt tensioner has better belt wrap around the crank pulley, do i have to repmace the timing cover ( id rather not) I was thinking about ditching the dayco tensioner for a thump racing tensioner so has anyone tried these out they are expensive but id be willing to pay it if it works if i buy it and have the same issue im going to be pissed. so What are my options i cant replace belts all summer long who has experience with this?
