I put the Steeda UDP on worked for about a week and made it through a Dyno tune then I started to get a Squeek which turned into a squeel. First after discussions with people decided it was a premature tensioner pulley. So I changed the tensioner and still the Squeek. Finally took a look at the balancer pulley it was running true butthe bolt was pretty easy to remove. I had torqued it down to steeda spec it said tq to like 89 then back off and tq to 65 or somehting like that i don't remember off the top of my head. While I was my performance shop trying to figure it out they said they put them all on with an impact and have never had an issue. So when they took the impact wrench to it it went on another 16th of an inch then half a turn and now no more squeel perfectly fine. The other option might be if your water pump pulley has holes in it it might just be whistling becasue of the airflow.

The high torq is to seat it. Then loosen it and re-torq to the lower setting.
While using an inmpact wrench to remove the bolt fine, it is not calibrated and has an unknown setting torq to install the crank bolt.
Make sure you change the belt when you install the pulleys also.
Most of the squeal can come from an old belt.

Most of the pulley systems for the S197 do not require a belt change. My tensioner does sit closer to the stop but this might just be Steeda's spec for usingstock belt. But spdbrake is right about it might be the belt. It is the belt, pulley, or a bearing in an idler pulley.

thanks for ur help..yea i had changed the belt..already i ended up puttin on the GATORBACK belt but i'm pretty sure its got to be the torque issue..my cuzin was sayin up & down it has to be dirty so i know its either dirty or its loose..thanks for helping get my 06harley f-150 back on the road..
