TT kit = pinned crank?

Should I go ahead and pin the crank while I'm putting on my TT kit? It was brought to my attention that even though I don't have the extra strain on the pulley from a supercharger, I will have the extra torque that could potentially loosen the crank bolt.

Good idea, bad idea?

p.s. Stock LS6 bottom. I will be tearing it apart anyways to replace the 3 problematic cam bolts with loc-tited ARPs.

It could be beneficial, but fwiw, I didn't have mine pinned with my TT kit.

I see no reason to as it’s not a power take off for power adder. The extra torque has nothing to do with accessories so skip it as its not needed.

No pin here, but with 720+rwhp my belt definitely slips on the accessories. On the dyno you can see the underhood light go real dim

I always knew you were going through supercharger withdrawal and even your car is letting you know.

Yea, a friend of mine on here (SprayedC5) was having horrible trouble trying to keep his on. He has a sprayed 402 that apparently didn't get along with it's crank bolt, as it was constantly trying to give it the boot.

He pinned his and the problem went away.

Where's the best place to pick up a pinning kit? I'd rather do it and not need it, then need it, and not have done it....

....or something like that.

Hahaha, no SC withdrawal until I start using up my AAA tows again for belt snap/ripping issues.

If you pin it now, you'll have problems later if you decide to replace the balancer cause you'll have to redrill for the new one.

Think of what you'll have to go through if you need to get back in there after-the-fact. Any % chance it can happen is reason enough.

Same here. Once @ Phil's (Road Rebel) and after getting back spun off again in about 500 miles. The problem is when you spin the tires hard with the rpm shooting up so fast the accessories can catch up and adds tremendous load. Pinned it no problems since.
