Guys, serious questions here. What does the stock pulley even do. And how does the ur pulley effect anything. Also how easy and how do you install it?

tenzingsherpa

the stock pulley turns which in turn makes the other pullies turn. Now I just had the UR underdrive pulley installed in my 03 honda accord v6 which is basically the same engine u have, and like it so far. The UR pulley which is lighter by like 7 lbs frees up hp that would be taken away by the heavier stock pulley. Replacing the old pulley with the UR pulley really doesn't give u more hp, but is like losing another 200lbs off ur car due to lighter rotational mass. This in a sense make ur car feel lighter, and accelerate a little quicker. I would recommend that u have a dealership/mechanic install this unless u have a 400lb/ft air tool to take of the crank bolt. I went to the stealership and they charged me $120 dollars. I love this mod but don't think it was worth $200 dollars. goodluck man!!

Wow...so helpful! I seriously understand it now. I am getting an unopened one from someone for like 140 bucks!

It definately smoothed out the rev across the powerband and yah its a bitch to install... but it you use just the right amount of heat from a torch on the Crank Bolt WASHER NOT the bolt.... it will come over relatively easy... just keep a blow gun close by to cool things once its off.

I personally didn't use heat to pop the bolt but the tool to hold the stock flywheel is a must.

A 4ft pipe on a 1/2" breaker bar worked for me. Sounded like a shotgun blast.

It had the same smoothing affect on my car as well.

The UR pulley is a lightweight pulley. The factory pulley is about seven pounds and the UR is about one pound. These crank pulleys increase performance by reducing the engines spinning weight and also because they underdrive all the accessories (a/c, alternator, p/s & w/p) (if you get the underdrive). If you get the stock size the gains occur just from the lighter weight.

Exactly right on all points.

I was attempted to install my pulley this weekend, but couldn't get the crank bolt to come loose! I was using a 25" long breaker bar on the bolt and a 17" on the powerbuilt tool to hold the crank in place. I was bending both bars. I don't want to use heat, so does anyone else have ideas?!? Also, to loosen the bolt do you spin it clockwise or counterclockwise? I was trying counterclockwise, but a friend suggested I try the other way.

It is counterclockwise. I actually laid under the car, put one leg up on the inner fender(passenger firewall) and pushed. I have done 2 this way now. It seems like the bars are going to break, but it will release.

It's a regular Lefty Loosy bolt.

Go to Lowes. By a 4 foot peice of Black Iron Pipe (it's pre-cut and costs ~$7). Put that over your breaker bar handle. Now you've got a LOT more leverage (and rigidity).

The other bar (holding the pulley tool) has to be wedged against the floor or something similarly strong.

I wedged the breaker bar on the holding tool against the floor

Then using an extension that would reach outside the fender well supported by a jackstand, leaned on it with the long pipe. It didn't break immediately. I kept leaning on it in a sort of bouncing motion until it popped. It does flex quite a bit with the long extension. I wasn't sure if it was the socket, bar or bolt that broke.

Thankfully it was the bolt.

Now that's good stuff! Just what I needed! Thanks fella's. I'll be giving it attempt number 2 this weekend if I have a chance.

Now, the question is, is there a video showing the install? I have AT so I can't just put it into 6th and hold the brakes.....seems like I have to remove a cover plate from what I've read, but I'm not sure what to remove. Any input on this?

Black_05_TL_6SP

There should be a cover plate on the transmission or the engine that allows access to the flywheel. Since I have a 6MT, I am not 100% sure, but I think it is on the engine. You should have the starter on one side and the cover plate on the other.

pohljm

wedge your breaker bar against the ground and tap the starter and your done

Bearcat94

Not sure if you want to do that with an '07 or '08 with the "one touch" start. It'll crank several trying to start the engine.

Wow, I've heard of people removing the bolt that way, but not tightening it.
