I recently lost the crank pulley on my Tahoe fortunately the pulley was the only thing damaged.Magnacharger sent me a pinning kit at no charge to fix the problem.Have any of you guys experienced this type of problem?A pinned or keyed crank pulley is deffenently worth considering.

For my in-process project, we did key the crank.

1)Can it be done in the car?
2)Can it be done by any speed shop? Nothing specific to the ls1 design?

Magnacharger sent me their kit.It consisted of a drill guide/spacer,drill bit,reamer,two hardened roll pins and longer bolt.The pinning is done with the engine in the car.

I would always key the crank. I lost a crank pully at 80mph, and it launched itself under the car and tore everything up from the oil pan back to the mufflers, and lifted the car off the ground so I could not steer for a minute...I was on a bridge too..
Anyway I have had a procharger on my car and you should definetly key the crank.

The crank was not hurt one slight ridge and some black metal residue from the ruined pulley.I was very lucky.
