I just picked up a brand new Steeda underdrive crank pulley for $70 bucks including shipping off of stangnet classifieds. That's my project this coming weekend. What do I need to look out for on the install? Thanks.

John,
Excellent find! Make sure that the seller includes the starting bolt used for installation only. Once the pulley is started on with that bolt it is removed and replaced with the factory bolt which is tightened and torqued to spec. Also make sure you follow the instruction to use silicon sealant in the keyway and notched area otherwise you'll evetually have an oil leak.

i STRONGLY recommend you get the October issue of 5.0 & Super Fords!!!
it has a step by step picture instruction on how to pull and replace a crank pulley. it is INvaluable if your going to do it!!!
most people need a 3 bolt puller to get it off, many parts stores know how torent one or you can buy one!!!

Rod, you can buy the same crank pulley from ASP. ASP makes the Steeda pulleys. The ASP crank pulley part number is 527300 and is $140.00. They are out of stock, but should have some in 2-4 weeks. You can e-mail them at [email protected] However, if you keep your eyes open on stangnet classified ads you can pick one up for much less.

I just finished installing the crank pulley. You will need to purchase a belt that is 2 inches shorter. I'll let the hi temp RTV set over night and try her out tomorrow morning. The install was a breeze. About 40 minutes. Auto Zone loans out the 3 bolt puller for free.

Here is a link to a good blow by blow procedure on how to do it...

Why did you need a shorter belt John??? I have used the stock belt in all of my installations.

Arthur, I had also read that the stock belt should be used after installing underdrive pulleys so I was a bit concerned when the tensioner didn't take up the slack on the stock belt. The stock crank is about 7 inches in diameter. The Steeda crank pulley is about 5 1/4 inches. The belt I had to purchase was exactly 1.7 inches shorter than stock. Can you measure your Steeda crank pulley diameter for me and let me know? I know I put the belt back on correctly because I did draw a picture of how the belt goes before taking the tension off. Thanks.

John

What kind of performance increase do you expect with the new pulley?

Bullitt 4542, our Bullitt only come with underdrive waterpump and alternator pulleys. The crank pulley is the standard GT pulley. So to have a "true" underdrive pulley set in your Bullitt you need to change the crank pulley out. I would estimate that changing out the crank pulley is good for 4 or 5 more HP over stock and some more torque. Best mods for the buck are an X Pipe, crank pulley, DenseCharger and chip...in that order.

John,
I just got back home and checked everything out with a tape measure. The results are below.

Alt: stock-2.5" Steeda-2.5" BBK-2.5"
Crank: stock-7.0" Steeda-5.25" BBK-5.25"
Water: stock-5.5" Steeda-6.50" BBK-6.50"

Arthur, thank you. As you know I am using the stock alternator and water pulleys with the Steeda crank pulley. So it looks like your net difference is .75 inches where my net difference is 1.75 inches. Why would Steeda and BBK go larger on the water pump pulley on an underdrive pulley set? My temp and voltage guages read exactly the same after installing the Steeda crank. The only thing that is causing me some concern is that it seems the RPMs hang at about 1100 for a second or two before dropping to 700 when coming to a stop. I don't recall that happening before the mod.

John I checked with everyone I know and all are stumped. Good news is that since everything goes to normal i.e. steady idle then you shouldn't have any concerns. Just continue to monitor but I personally don't believe you have anything to be concerned about. As for Steeda's and BBK's choice on water pulley size I guess it's part of their overall design package to further reduce engine drag by slowing that accessory down.

Stupid question, but how much of a difference does the x-pipe make over our stock exhaust? What does it look like other than the obvious X? :smile: I mean, does it simply have an X in the place of our H on the stock exhaust? How hard is it to install one and is there any modifications that need to be made? Lastly, does it sound any different?
