Just wondering how hard the udps are to install,and how much of a gain to expect.Looking at steedas from brenspeed.Comments would be great.

Supposed 10ish HP, I haven't heard of anyone dyno'ing with just these installed though. I have mine still in the box, looks VERY easy to install (too exhausted to install them after putting in my L.T. headers, x pipe and h/f cats this week. Got mine from Brenspeed as well.

just a hint that will save u a headache and the need to kick ur own ***:

there is a washer in the middle of the crank pulley that gets rust around it and looks like part of the pulley. wd-40 it and take it out so the pulley puller can actually push against the crank and not just push the washer into the pulley (doenst hurt anything, just sucks when u figure out uve been doing that for 20 min) the pulley should come right off, like... ur little sister could turn the wrench to take it off. if its hard, u may not be pushing on the crank. Now, to put the new one on: RE-INSERT the washer!!!! or u will just be using that long "pulling" screw (if u got steedas) to tighten down right to the crank, and it wont actually pull in the pulley. I did both of these things cuz im retarded....... if u think it through you really should be alright. also, in my car the alternator pulley neck was too short. when it was impact wrenched down, it touched the casing and wouldnt turn. I went to a semi-starter shop and they had a little ring that was made specifically to fit in there and set it at the proper distance from the alternator (if the dist is wrong u can mess up ur belt over time)

EDIT: although, ur car might be setup different.... just heads up
