Looking to purcahse a UR Pulley set on the 3G and i have been reading some threads but i am looking to see who all has installed them, who enjoys them, and who has had any kind of problems with them if there were any and what they were.

There are many many Acurazine members on this board with the UR crank pulley. The UR pulleys are well-made and of high quality. They free up horsepower by reducing parasitic loss. There are no issues to date that we have encountered and there are a number of J-series motors will 200k+ on them with the lightweight pulley.

There is no pulley set currently for the 3rd gen TL. Most of the gains are from the crank pulley.

Josh summed it up nicely.

OP, many pro/con views expressed in this thread:

I was going to add a UR pulley during my TB change out but decided against it.

Hopefully some of those Azine members that Josh mentioned will chime in.

I had a stock sized UR pulley on my 06-6MT. I felt that it accelerated more quickly and when running slowly in a lower gear, the transition off and on the gas was much smoother.

The only reason I took it off was I went FI and I am going to be replacing the clutch with a LW flywheel. If I stayed with bolt-on's, I would have left it on.

I have the smaller crank pulley from UR, not installed yet. Getting timing belt done this weeks so I will let you know how it feels soon.

i sort of with mayron on this, but i have the stock size lightweight pulley. getting my TB serviced soon and my mechanic was cool enough to put the pulley and side motor mount for the same price he had quoted me without these. i was gonna install it a few weeks ago and he told me about the motor mount being broken, so im waiting for it in the mail. thats why i added the pulley to my mods in my signature. i will report soon.

nfnsquared

Hate to burst your bubble, but your mechanic isn't really doing you any favors. Both the side motor mount and crank pulley have to come off anyhow for the timing belt change....

I have had the UR stock diameter pulley on my car for about a year and a half, the install was cake (i did the breaker bar lowered to the ground and cranked the motor once with the fuel pump relay off). I havent had a problem at all. I did see very good gains from it too. My friend and i would always do a mod and race and he would beat me then i would mod and i would beat him and after i did the crank pulley he was like "WTF?" So i highly recommend you installing this if your looking for a noticable gain....or "free up of horsepower"

I second this...

But i ran an underdrive on my car for a while and the only reason I got rid of it was i went to a S/C. I have had one on my MDX for 3+ years with no issues. Felt great, feels like the engine doesnt work as hard.

Bearcat94

Stock size Crank Pulley, 2 1/2 years and ~29,500 miles. No issues.

Some one did a theoretical calculation on gains based on reduced mass. IIRC, that indicated more gain in lower gears, which I think makes sense.

jr27

yeah i guess ur right but maybe another mechanic would have taken it off and then once it was there put it back on and then charge labor again? idk but this guy is a good guy, he even showed me where to get his direct price from and i did same some on the motor maount paid 53 bucks with express shipping and tax. when my local autozone wanted 98 and they had to order it, acura wanted 138. but i do see what you are saying and he did tell me that too he said i need to get them off anyways.

same thing i want it for bro, a buddy and me always do this too and yesterday he beat me he added cai and mufflers to his 05 maxima manual. before these mods he just did, he would get the jump and i would beet him as soon as i got to third gear so im hoping that with this pulley i can at least be dead even from a dig

04_6SPEEDTL

It most def should!!!, funny you say that my friend had a manual altima haha

akertulis

sounds like its a needed part for fun will be purchasing very soon.

which one would you say is the one to go with?
All i will be running is j-pipe and pcd's no sound system or anything that will take power away just the A/C in the summer time which i barely use anyways

jr27

i believe that if you go with the smaller one you will need a smaller belt too. if you have no plans on doing a supercharger or sound system i would go with the smaller pulley. only reason i got the stock size is because i plan on doing a supercharger in the near future, i may put some subs i have sitting in my garage, and i had already bout the belt for my 105k service. so the stock size was the one for me.

akertulis

yea no future supercharger or system for me

I highly recommend them, one of the best bang for the buck mods in my opinion. Had many customers install them on their Accords with great results. One customer dyno'd the underdrive on his 08+ Accord V6 and gained +9 hp and +20 ft lbs of tq to the wheels!

akertulis

what belt is needed to run the underdrive pulley

Not trying to be that guy but the "gains" are minimal. 20 lbs of torque I would love to see the dyno on that. Although there hasn't been any problems, I have always been against these things. I feel like it over works the engine, and will wear out the engine faster. Its almost like riding a 21 speed bike in a lower gear all the "gains", if there is any, would be take off (low rpms). We all know take off we don't need power, its the higher RPMs. Our cars with FWD is a problem already so tracking isn't there to begin with. Best bang for the buck would be the J pipe or Pre-cats because our exhaust is very restrictive and making it free flowing really does wonders.

I don't even wanna start with the TB spacers and how much they are a fail for our cars.

akertulis

well i def dont want to put wear on my engine especially since i have 114k on it as of now so ill have to do more reasearch on that one

myron

I don't think that anyone has had any "premature wear" on the engine from being "over worked" by this pulley. That's 7 years of 3G TL and no one has complained about it.

And the engines aren't overworked by this mod, it's by people thinking they got a "go fast" mod so they bag on their car more.

Not a problem at all - that's why we have these things dyno'd. Hope theres no issue with linking to another forum, but if there is just contact us. Here's the thread for the underdrive crank pulley on a V6 Accord AT : http://www./forums/showthread.php?t=52533

Here's the thread with the before (so with the pulley installed) and after with P2R Ported intake runners, thermal intake manifold gasket and throttle body spacer : http://www./forums/showthread.php?t=52866

I don't think I understand the wear comment either, how would putting a much lighter pulley on the car cause wear? If anything the engine is having to push less weight around. And throttle body spacer, hopefully we'll get a dyno on that individually very soon for you, but many customers on the Accord platform have really enjoyed it (same part). Of course it's a minor mod for the cost, but definitely something worth a few extra HP that's been dyno'd on various Honda's and looks great in the engine bay.

Correct, it's similar to intakes and other items that would actually help the car run more efficiently, but with the extra power many push them a bit harder which nullifies the benefit

I was just under the assumption it would throw off the counter balance and pre mature the bearings. Its still up in the air is its good/bad and like I have said before, there are so many more people with 3G TL's that aren't even on this website. I wouldn't say its "bad", but even some reputable mechanics are 99% and won't give me a full "its great". If you have the S/C, do NOT get the under drive size.

Did you all know J&R isn't the only one making Turbos for our cars? There is more then the comptech super charger for our cars as well. I have seen custom exhausts, custom J pipe and much other things that aren't from our vendors. There are so many people with these cars outside of this website, everyone would be surprised what kind of custom work people are doing.

As far as TB, most of the time they are made wrong and produce air blockage leading to a decrease in HP. Me or my reputable mechanic that works on Honda/Acura's has yet to see one that gives positive results and have only see them give negative results.

Let me know when you get that Dyno.

Fortunately, this isn't an emotional debate so feelings don't count. Actual experience and use has demonstrated no premature wear. Gains have been documented in the low and high end. Yes there are parts that make more power but the light weight crank pulley is also a power adder.

If you'd like to see some of the dynos use this link:

As I heard somewhere, Assumption is the mother of all fu*kups.

The pulley issue has been debated to DEATH....no clear winner either way except to say no one has been able to prove premature wear or failure from having the pulley installed.

I'd like to see what other people are doing, do you have links to all the other turbocharged 3G TL's out there?

AckTL05

iTrader: (18)

No links. My tuner has tuned about 3 of them he said and one was there the first time I went. My tuner also can make a set up. Its not so much the turbo thats the problem, its the custom piping. If you can find someone that makes custom piping, he/she would be the one that can make the Turbo.

I will try and get him on here. I know paul (NVA-AV6) makes them and he currently doing a custom TT build for someone, I will let him chime in.
