Steeda Underdrive Pulley install (with pics)
Around 5 hours, but that was doing the CMCV Deletes at the same time. Picture taking and lunch included.

Engine rev's up quicker in neutral, so it must have lifted some of the accessory drive drag.
As far driving around, in my short (and not too crazy) test drive, I can't say that there's a world of difference. Only that it feels just as strong in the bottom end before this mod. Keep in mind that it's coupled with the CMCV Deletes.
Like I mentioned in the CMCV post, these 2 mods are being overshadowed by the 4.10's. Even though I'm sure that the UPD's and CMCV's will show an improvement on the dyno, all the neck snapping is coming from the gears.
I haven't cycled the A/C on yet.
I do know that Steeda engineered these pulleys with Ford Engineers. So that's got to be a plus.
I had mine in Reverse.
I thought about trying other gears, but then decided to pull the fan for the write-up. At least that's my story.

Maybe post this question in the Audio Mods section. Some guys with high-powered stereos and amps can better answer your question.
I believe there's several online suppliers that you can order from.
Gear puller and harmonic balancer install tool are from Blue Point (I think they're a Snap-On division).
Congrats on the install on the UDP's! & CMCV deletes! My only question is what took ya so long for these mods!LOL I noticed a slight difference on on reving the motor after installing my UDP's . As always bill nice write up. I still need to get the delete plates. Just waiting for Fast Perf intake to come out this summer and see what the gains are with it before i get the deletes since their intake will have them on em.

I was on the fence with these 2 mods. Recently decided, what the heck, and got them. After I get my C&L Racer, that'll be about it for simple bolt-ons.
Here's a question for you Billster:
Any advantage to doing the pulley's and delete at the same time?
Not sure I have the energy to do them both at the same time but individually I think I could handle ha
Good stuff Bill
And how about those valve covers.........................still thinking on those?

In hindsight, I should've just taken a heatgun to the new pulley instead of boiling it.
But, to go through the experience was worth it. And, I probably wouldn't have wiped down the pulley with brake cleaner because their wouldn't have been any melted plastic on it. Thus, my pulley would've still been black. But, I do like the look of my shiny pulley though, just have to keep it wiped down with WD40 so it won't start rusting like the factory pulley.
The order is already in for my FRPP camcovers.

Then what color did we order for those CamCovers? Something freaky or something along the lines of your current color scheme?
Trying to keep up with you Bill is useless

You know there's red someplace on these new CamCovers, thats a given lol
Fooled again "Polished" e-gads Making pretty are we Bill The garage Queen label is so justified
I'm in it for the long haul so I'll just keep chipping away Bill, although I might not close the gap I will get closer to you. lol

As far as no more simple bolt ons...don't forget one-piece driveshaft and adjustable control arms!
Yeah, me too, didn't do these right away. I'm about two months ahead of you on the CMCV's and UDP. I put the balancer pulley in a small toaster oven cranked all the way up.

I'd entertain the 1 piece driveshaft, but I have 2 concerns..
I wonder if it will have clearance to the MGW Shifter?
Until I stop reading posts about the vibration issues (at hwy speeds), I don't quite get that 'warm & fuzzy'. Could be the way they installed it though..
