Hey Guys,

I'm purchasing a Whipple HO kit from Lethalperformance soon.
Someone told me it would be better to replace my Steeda UDP's with the stock ones for this.

Unfortunately i have lost the stock ones, a friend of mine has a set of the original pulley's because also placed a Steeda set. He's car is a manual '05, mine is an auto '07. I dont think there should be an issue if i were to use his, but i just want to be sure.

Can i use his original pulley's?

Without knowing the Ford part #s on your lost 05 pulleys,
its hard to tell.
First find an AUTO 07 out there with the OEM pulleys and get
the part #s off them.
Then compare them to your buddies 05 MANUAL pulleys.
If the first part of the numbers match, its a go Houston.

Yes

Make sure you buy a new crank pulley bolt. They meant for a one time use.

I traded in my car and left the Steeda's did not want to risk F'ing something up.

Agree with the rest its the same, just make sure you use the new bolt check to see if the woodruff key Is not damaged check the seal to see if you have a leak clean the old sillycone and use somenewone.

Just out of curiousity, how much HP is lost if you leave your UDP's on? Anyone know?

It's not an exact number. It will lower your boost by underdriving the supercharger pulley.
