Hi everyone,

At this time my ATI pulley part # ATI-918853 has Vibration and time to change it. Which ATI pulley for Supercharger engines with A/C for LS1 applications? or any advices for better pulley?

8-rib pulley system.

Thank you in advance.

 

I'll have to kook at mine when I get home this afternoon. It has an extra pully for the A/C that bolts on thru holes already in the ATI balancer. You may only need the extra pully & special bolts. I'll update later today.

 

Please check on this video of mine

I can't see the vid, listed as private.

Can't tell from looking at it what p/n my ATI balancer is, probably this one: ATI 917277. Does not look like it has the A/C pully with it, my A/C pully attached with the 3 12point bolts that are not flush with the surface. Description in Summit Racing's on line store says it's for cars w/o air conditioning. There's probably another part number for one with the A/C pully but I couldn't find it. Hope this helps.

Thanks, I'll get back to you today. Bob

 

i have the 917276. why is the 917242 better? it is larger so it probably dampens better. would it be wise to upgrade or can i not even use the one i have with an 8-ribbed procharger?

 

Your 917276 will work just fine, we have used it with many installs. Bob

 

I have a 917242...that should work for a gto d-1sc kit right??
