Hey Peeps,

I need some support from you guys on this matter. I took the Max to my normal installation shop and they informed about a situation with installing the UDP.

They stated that they might be charging me an extra $200 because they must remove something from the upper engine bay...

I plan on installing 3 mods and one being the UDp. The install for all 3 was to be $400 but with this issue then Im looking at $600 which is ridiculous IMO.

Please post some info on how you guys installed your UDPs in detail so I could print out and bring it to these fools.

Thanks homies!!

 

The only thing they need to do from the top of the engine is loosen one of the tensioner nuts.The rest can be reached from underneath.

 

What shop is it? Midas?

Some of these places don't realize you can access the belts through the front wheel well. So instead they charge you to essentially tilt/drop the engine to get to the belts/pulley. Explain to them that they just have to remove the tire and unsnap a few plastic rivets to access the pulley/belts.

 

You know my thoughts on the matter, total B/S in my opinion, passenger wheel off, plastic wheel well cover off, Pulley right in there face, NOTHING and I mean NOTHING to jack other than the fact they are trying to jack you for an extra 2 bills, you can quote me on it and you have my private number that the garage can call me on if any of those chuckle heads want to challenge me on it!!!

Peace bro, us Orgers need to stick together...

 

I had a friend help me install mine. Now that its cold it squeeks alittle. Dont think its the belts because if you rev it or at idle it doesnt change. Any ideas?

 

Belts probably need a little more tension.

 

Thanks, will try some belt conditioner and then check the tension.

 

is it really worth installing a under drive pulley?? what do u gain?

 

Freeing up a few whp by the weight reduction and under-driving the components.

 

Yes and hell yes.

Just make sure you order the Cosmo Racing one (www.cosmoracing.com). Its like $65 shipped. Looks almost identical to the one in Chern's picture at 1/4 the price.

 

i got mines installed for $20 bucks at my cuzins shop

 

Chern's has 10 holes and cosmo has 8...so is Chern's weigh less?!

30 dollars bucks? Kind of repetitive while saying the same thing...

 

lol

 

Mine didn't have any holes...

 

What do you think the differences are between the two besides the holes?

 

slight weight difference

 

Enough to make up for the $150 some difference?

You think that they both have the same diameters?

 

Agree, great bang for the buck!!! but only 1/2 the price...

 

Guys is the one on COSMORACING a stock diametter? just lightweight? cuz im planning to get me one Thnxs

 

no...it says "underdrive" in like 3 different places

This is exactly why I am scared to do my own installs...

What the heck is a tensioner nut??

I look in my engine and I see 20 million nuts!! LOLOLOL!!

 

No the shop is called EZ Concepts

They "Spealize" in installing performance parts.

I am very happy you stated what you did...

Thanks bro!!

 

Thanks again Chris!!

I have a little more back up now and if I get a bit more feedback from the rest of the familia then I can bring the proof to these guys at EZ Concepts.

 

LOL, No problem, I just wanted to ensure your installer stuck by his name and kept the install EZ...

 

Also on the top tensioner nut its not the typical righty tighty, its the opposite I believe. If they do it like regular it will snap rather easy.The outer belt is the top tensioner nut with another one nut just below it. The inner belt has to be done down below. Did you get instructions with it?

 

Nothing to touched up top when they installed mine. Sounds like they spealize in ripping people off unless maybe that includes all new belts.

I've got the UR SC pulley (stock diameter, not underdrive). I was there the whole time when the tech installed it. He jack up the car and replaced the stock pulley. No belts were replaced so maybe that's why he could do it all from the bottom, but I doubt it. $200 is just way to much to put that pulley on, it my guy about 20minutes.

Stock pulley on scale

Installed SC pulley.



Here is an UR underdrive pulley side by side with the stock pulley

 

The accessories belt is stock size. The underdrive belt is the power steering.

 

On my 07 I had to(or atleast I did) loosen the nut up top along with another associated nut for one belt and the other belt can be done from underneath.

 

But you have a STOCK sized pulley...so why that pic?^

How much did you pay for the stock sized pulley, and have you had any issues with it?

 

1. Just because I had the pic and I thought folks might like to see them side by side.

2. UR pulley is not cheap...it was like $170. No issues at all. That UDP is still available to me, I may give it a try this spring.

 

Great info guys!!!

Redls1.... I still have no clue what your talking about bro... lololol

 

Look in the ma.pdf section of the service manual. It shows what Im talking about the 4 nuts and you have to access the tensioner nut from above. My directions I received suck. Sent you a pm.

 

Roger that bro. Thanks for the PM BTW

My plans are to print everything from this thread and bring it to the shop.

Thanks again everyone for all your inputs

Merry Xmas!!!

 

Well just installed the unorthodox and first off very nice craftmanship and build quality. I remember the timing marks on a previous post with the cosmo racing and how sh#$ty it looked, so went with the unorthodox and am very pleased. Deus did a nice write up before, but one thing that I want to add is that when loosening the tensioner bolt on top of the engine, you have to loosen the actual tensioner bolt itself to free up the belt. That part took me the longest and everything else was just gravy... I did have to go with a smaller belt instead of the Gates K060408, I went with the K060407, which was perfect. No squeels as of yet and will await a dyno to see. Weight difference as Apollos has showed is huge. Had fun installing.

 

You probably have it in already Grim but let me tell you this. DO NOT DO BUSINESS WITH EZ CONCEPTS in bay shore and now theyve moved by babylon. They can do simple stuff for you but thats IT the guys in the back are usually very amateur when it comes engine work. The head guy there is named Jaime he is coo but usually he is working on the owners car "Hersh" and wont be avail to work on yours. Take it to another shop man if you want P.M me i know another shop in b wood or smithtown that can handle our cars with no issues.

 

vigalantemax, do you have the link for deus's writeup? i plan on getting the UR pulley but the ultra Sc [021011012] not the ultra s [021011002]

You do realize that the Sc is heavier?

 

It's stock diameter though

 

I know but the only thing you would change is a belt on the s version. if the purpose of this is to decrease workload so to speak from the crank, then increasing the weight is counterintuitive.

 

Ultra SC is lighter than the stock by a few pounds. Its probably only ounces heavier than the UDP version.
I am running the SC version. Is there any difference in whp gain? Only the dyno knows, and as far as I know, no one has spent the money to do a before/after on their pulley swaps.
