Ultra S Unorthodox Racing Underdrive Crank Pulley

[Shades]

Put over a thousand on it over the last 2 weeks, still more smiles than miles.

The queerbaits I ordered my belts from gave me 2 of the same belt, so I ended up having to use one of the stock belts with the tensioner pushed out a bit further than normal, and after 1000 miles, it's still fine (though I do have an extra belt now in the trunk just in case...)

As for putting it on, u can do it just by opening the hood and jacking up the car easy enough. U might get burned on the valve cover if u can't wait long enough to let it cool, and might cut urself getting some of the sockets on, but it's not too hard, but hey, that's working on a car for ya

nice to know. You just have the UR pulley right? so you are using the stock belt? I had to adjust the tensioner to get the belt tight for the indigo pulleys, but still no slipping.

 

[P-Funk!]

Ok! Based on this - i went to unorthodox and bought the pulley! I didn't see the p/n for the belt tho'...

What is it - so i can install it the day i get it!!

It will be in the instructions included for your vehicle. It is also on their website since i have spoken to them about it specifically, look for vehicle installation instructions or email them.

I've been running the UR pulley now for about 5,000km. No problems what so ever (using Gates belts btw). The gains are very noticable in the lower RPM range, but like mentioned stretch throughout the powerband.

So guys I need a little help here. I have decided to do the install myself but how do you loosen the crank pulley and keep it from turning? What's the secret? I have an automatic. Does anyone have a shop manual?

The way I did it was to have my wife in the car, have her put it in 5th gear, and then mash the brakes. Another way to do it would be to drop the oil pan and wedge in a piece of wood between the crank and block. You can also try an air drive, but my 1/2" wouldn't touch it.

with the automatic, we did it with a chain wrench on the hill between the belts. (Or, if you don't mind possibly damaging your pully, just wrap the chain on) You just gotta clamp it on, move it so it's braced against something, then turn the bolt with some good force, and ur in business.

To get it back on, I wrapped one of the old belts around the UR pulley, and clamped the chain down on top of that. Hope this helps

So is this UR pulley the stock pulley's size? Haven't researched it much...Lots of cars have smaller ones, and bigger ones available...for different types of benefits...The oscillation rumors will most likely never come into play until huge power mods are made, so you guys have absolutely nothing to worry about reliability wise I would imagine...I wouldn't do it on a cast crank, but ours should be fine...

its smaller diameter and lighter. I personally had the pulley installed by a good shop enar me, it wasnt expensive either. Some things i will work on but the pulley location, lack of a lift, and the little space in which to work made me shy away from a DIY project. Otherwise install is right about the fact that this pulley seems to be reliable.

I did it!!! Thanks for the suggestions guys but since mine is an auto, it was alot more difficult than I expected. One problem was getting the bolt loose but it's not over yet. After you put the new pulley on, you now have to torque that to 121ft/lbs. This was definitely a difficult project if you do not have the right tools. I took it for a spin and I did feel a difference early in the rpms but I didn't really push because I think I still need to tighten the belts a little more. By the way, how much tension should I have on the belts? How do you measure it? I had some squeaks which tells me that I need to tighten them but I'm afraid to over tighten them.

How I got the bolt loose:
- The stock pulley has these holes that bolts go into and are raise so I was wedge something against it.
- I took the bar for my hydraulic jack and wedged it against one of the bolt holes on the pulley. The bolt hole was at about 11 o'clock.
- I laid the passenger side tire on the ground and stuck the other end of the bar into the lug nut hole of my wheel. What was good about this is the tire did not slip and it allowed me to crank the bolt loose. Finally!!!

How I tighten the bolt on the new pulley:
- I took the longer of the old belts and wrapped it around the pulley but folded one side of it and wedge it underneath the belt. This way as I tighten the bolt, I would just need to anchor the other end of the belt and the pulley wouldn't turn.
- I accomplished this by sticking a bar through the tow hook and anchoring the belt on it.
- I sat in front of the car and I held the bar as I carefully pushed my 21" torque wrench with my foot until I heard the long awaited click. "CLICK" Holy s***, I did it!!!

Damn that took me forever to do. It better be worth it. Good luck to you guys that have yet to do yours. I will report back after 1000miles.

i just bought this and need to go get the belts now... So how far is too far when tightening these belts back up, I dont want any squeeking?

I have been adding tension little by little if I hear any squeaking. I think I have finally reached the point where it won't squeak. I had the same question so I went to Autozone and checked how to tension the belts in one of the shop manuals. It said that as a rule of thumb, if the distance between the center of one pulley to the other is 7-11 inches, then the flex halfway between them should be 1/4 of an inch. If the distance between the pulleys are 12-16inches, then the flex should be 1/2 inches. Mine is about the there. Hope that helps.

I just installed my UR pulley this weekend, took about an hour. I love the fact that I only paid $100cdn with a belt used from one of my fellow club members on toprotege.com. I also love the fact that my father is a car god and did most of the install, except when it was time to go under the car, he usually gets me to do the dirty work. He just knows how tight the belt has to be by looking and feeling it, i feel very fortunate. Pulley is great, epspecially for the price i paid.

Protege Speed... yeah that did help .. thanks (thumb)

 

[stdntDrvr]

i've had mine on for around 14K miles...i LOVE it.

 

[PR5Matt]

I ordered one but it was on EXTREME BACKORDER so I am looking for another vendor who stocks them.

I think they are on backorder from all vendors... try www.tuningdepot.com they have OBX pulleys although i have never ordered from them.
