Also for informations sake the blower pulley I will be attempting to fit is for a lt4 ctsv with the whipple kit. May be dead on but could require some adaptation.

Jared,

Was that everything you need short of the blower pulley? I need to get something going as I've got pretty bad belt slip.

I think I added one more larger idler to try after this order but other than that yes. I have the puller for the balancer coming in tomorrow and I’ll knock this out and let you know any troubles. I do have a spare water pump handy I expect that to be the troublesome one. But Chris rose from iw said he didn’t have much trouble getting his off his truck to spec out for the kit. The car pulleys can be a real pain but in the past the trucks have been easier for me. What’s your setup now? Pulley size etc

I know I’ve gotten by with adding the 100mm idler to get a smidge more belt wrap in previous builds.

Has anyone completed the 8 rib conversion? I've been desperately trying to figure it out I keep slipping/shredding belts on my procharger silverado any help would be greatly appreciated thanks

I’m doing it right now should be finished tomorrow . I’m supposed to write up some instructions for innovators West so I’ll post them here as well

I will say you will need an adp tool for the alternator, a three jaw balancer puller, and the water pump will use a standard three jaw puller and needs a press for installIng the new pulley. Removing the impeller/shaft/pulley from the housing is the only way to do it but it’s super easy if you notice there are 6 holes in the pulley which make it really easy to get to.

Also the blower pulley I’m using is a 3.00 from weapon x that is designed for an lt4 ctsv with a whipple. Lines up well with the other pulleys , this idler needs spacing away from the whipple idler bracket it rubs against it

And the water pump is a pain like the cars....

Ok I’m installIng the balancer today and pressing on the water pump pulley to the exact depth. On the two water pumps I have the pulley measures .6 “ from the back of the pulley to the face of the pump mounting /sealing surface. Should fire it up today but I had to order new stretch fit belts for the ac and vacuum pump

Got the last pulley on ! My belt calculation was about an inch off I didn’t account for the iw pulleys being different than stock diameter to offset the 10% od on the balancer . All pulleys are aligned within .005”!!!!! I think I get to say I’m the very first 8 rib l86!!!!
