Ok, I have had these BBK underdrive pullies with the piggyback crank set-up on for about a week now and the crank pulley is a bit wobbly? Is this normal? WTF?

Thanks.

Take them off and send them back and get steedas.

It's a little wobbly @ idle, but when I rev the engine it smooths out. With this piggback setup, the stock dampener bolts in front of the BBK pulley, it looks so stupid. The BBK pulley doesn't wobble at all, its just the Stock pulley........

The stock pulley acts as a damper, you need to immediately stop driving the car or even turning it on. Remove both pulleys and bolt them back together again, or find out if BBK makes a SFI approved underdrive crank pulley/damper.

Your messed up pulleys are going to be putting all kinds of weird vibrations & stresses on the crank.

I had this issue with MAC UDPs. I couldnt get the stock and mac pulley apart so i have had it on my car for a week. I am starting to hear wierd sounds from the engine. anyways, on monday i ordered Steedas from AM . They should be here today. I got the MACs for 50$ on ebay. I thought i was saving money. Now they are trash. i just hope the ticking/knocking sound goes away after i swtich them them out.

I though I read somewhere that the dampning affect of the crank pulley on the 4.6 is not as effective or is unneeded. It was more of a 5.0 thing. The steeda crank pulley is not near as big and heavy as the stock one is it?
