I picked up this s/c from a member about 2 months ago, and i am staring to get everything together for the install. I was told that some of the original bolts sheared or snapped. He had his tuner re-tap the pulley slightly bigger and deeper, and had no problems after this was fixed. I am concerned that the pulley may not be balanced since it has 12 holes in it now, and 6 of those holes have snapped off bolts in them.
Anyone have any input?

 

I you are concerned then you can probably buy a new one from SOS or CT.

 

Which i may do but i know there are several members who had this same problem and i am curious if they re-used the same crank pulley.

 

The motor is internally balanced unlike an American V8. I wouldn't be worried about this little of an issue. I'd hook it up and forget about it.

 

I can't imagine it being "that" off balance to make a difference

 

reused mine but i drilled and helicoiled some of them make sure to use loc tight on them

 

At 9000rpm it doesn't take 'THAT' much to be off balance lol

I think the OPs concern is valid, but I also don't think many people on here will know the answer, unfortunately.

 

i would go the safe route and buy a new pulley.

 

Thanks guys, I have my stock pulley that is untouched so i don't have to purchase one. I don't have the correct tools to do the job, should i just take it to a machine shop?

 

Yes any machine shop can do this for around $100 or less. I had mine done this way. I would bring your old one and bring the CT Pulley too so they can use that as a stencil if they want.
