Stock lower broke

[whipplesnake]

Was out enjoying my car the other day, and my Whipple quit making power. After freaking out for a couple minutes, I realized that my stock lower pulley was broke. I've never heard of one of these breaking. Has anyone else had this happen?

 

[SLEEPERSTATUS]

WOW! thats crazy bro, any pics?

 

[Jefe]

No way...Like in half and the belt came off?

 

[VincodeY]

crazy.

I pic wouldn't show any thing. The part that screws into the harmonic balancer , and the pulley move separately now. None of the pieces look broke, but with the car off you can spin all the pulleys by turning the charger by hand.

Wow, does it spins freely(meaning no grinding)? post up some pics when you get it apart. Can you tell where it broke? I'm thinking it may have broke just on the inside of the cage near the harmonic balancer.

Also how long has the blower been on the car and how much Hp and Tq are you making?

never heard that before

it's still on the car, but with they belt off the pulley spins free and the Allan bolt stays still. This really freaked me out when it first happened, because last year I broke the snout of my crankshaft,and when I grabbed the metco pulley it and the balancer came off.

Dude how tight are you belts? You broke a snout and now a stock lower? Id ease the tension up some.

The snout broke with a cageless metco pulley and a RR manual tensioner. Thats why my new motor has a stock lower with cage and a stock tensioner.

Damn, sounds like the pulley is press fitted on; I was hoping they weren't there goes my lower pulley project.

WOW, I guess theres a first time for anything.

I finally got the lower off and found the problem. The part that screws into the balancer screws into the pulley by the allen bolt. those threads stripped.

How did they become stripped?

:shrug: The only thing I can come up with is the drag from the Whipple . I did not even know there were threads there.
