I am looking at Mods and was wondering if a Pully is a good improvement or not? I see the UR makes a Underdrive Pully and a Standard..???

Any info or recommendations would be appreciated!!

Jeff

 

SS UR Pulley got it and happy!...

 

Nay.
From what I've read, seems like a waste of money.

 

Honestly I do not see a use for them but people like them. I prefer accessories over crank.

 

It increases 1/10 on your 1/4. Frees up 100LB, good for 6-7 HP. You may not feel it, but its there.

So many doubters because you can't prove it by a dyno. Its almost like you're driving your car minus 100 LB. Will it make a difference? Yup. Because technically every 15LB = 1 HP. Take out your seats, plastics, and excess material = lost weight = freed up HP = Pulley does that. Slightly better throttle response also.

 

Ill take a lightweight flywheel over a pulley. Does the same thing.

 

I just send a payment for it yesterday to a member. I am doing my timing belt soon and I got all the parts 60% off through my dads work. So I figured since the mechanic is gonna be doing all that work, may as well just throw that on there. I'll let you know if I feel the difference.

 

So when you say you free up 100 Lbs I am confused because I have read you only loss 8 Lbs by changing it out! All good info though and Myron I will look forward to seeing what you think after you get yours installed...

 

Correct, but the pulley is a lot easier to install and a fraction of the price.

 

True, the OEM pulley is only 7-8 lbs heavier then the UR Pulley. But the UR Pulley "spins" faster which makes it free "100 LB", if that make sense. Check up Innacurate's post about the Pulley, he has a more indepth information about the Pulley.

 

The only reason I see it spinning faster is because of diameter not so much weight. Weight has its play but not on spinning speed. UR makes two different types...an underdrive or an OEM style. Both weights are negligible. If I were to get a pulley I would just get the oem sized one. I have had a crank pulley on my old h22a accord. It didn't surprise me that much. Yea it revved up faster but thats the only benefit I saw. After a month I put back on an OEM dampener because it did not make that much of a difference to me also it was a pain in the ass to get off when I needed to do my timing belt. Took me 2 days to get it off with 2 different impact guns, lube, hammers blah blah blah. By the time I got it off the pulley was unusable. What happened was the woodruff ate into the aluminum pulley so it was a bitch to get off.

 

I've been considering the same mod & doing some research. I was gonna go with the OEM sized UR Pulley.

 

I feel like I've seen some posts on here of people saying its REALLY difficult to take off the factory one to get the new one on...is that true? Cuz if it isn't then this seems like pretty much the most bang you're going to get out of such little...buck.

 

Factory nut is easy to get off as long as you have a nice size bar and the factory tool.

 

Would it be cheaper to just take it to a shop? Or buy the factory tool and do it myself?

 

Everything will always be cheaper if you do it yourself.

 

Just from what I have read on this forum:

Some have had to reinstall the original pulley due to electrical problems

IMO: if the system could easily have handled an underdrive pulley, don't you think Acura would have put it on to begin with?

2nd: for those who reinstall the original pulley.....it's a bitch!

 

I've heard things both ways with the electrical, but keep it mind that is only with the underdrive, and not the lightweight factory sized pulley. I've heard people running the underdrive pulley with a full stereo setup and still not having issues. The only issue that I've heard the biggest problems with is the superchargerd TL's not building boost with the undersized.

 

Being the whole reason of changing it is weight reduction I am not sure why there is any real benifit to the Underdrive model! It seems that if they both weight the same there is no benifit at all to the smaller size!

 

I would think the underdrive would be slightly lighter. I'm not sure of the individual weights of either

 

the underdrive is the one that actually provides gains.

if ur auto the pulleys are void of gains.

i never felt mine on my auto so i didnt put it on my 6 speed.

ended up buying one again for my manual and the downshifts rev up so much faster and my shifts are smoother because i dont have to wait on the engine to spin up.

 

Why wouldn't the factory sized pulley provide gains? It is still lighter than the factory pulley, isn't it?

 

Thats what I am thinking Killersrt! The whole point is to free up rotational weight! This is no different than buying a light weight Crank for a car! It is attached directly to the crank so if you can free up 7-8 Lbs from stock that should be benifical!

 

The under drive pulley under drives the power robbing accessories and will free up additional power that the stock size pulley will not. Mind you it the difference is not much, but if you want to reduce rotating mass and get every possible horsepower out of that aside of a lightweight flywheel, the under drive pulley is the one to use. I've had mine for well over a year, and have had no electrical system problems at all. Although I am going to be doing my T-belt soon, so I hope I can get that bolt back out without a problem LOL.

 

i could get into the physics as to why losing 7lbs off the actual crank and losing 7lbs off of a smaller size pulley are very different do to where the weight is being lost (center instead of the end of the radius). but ill just say that i didnt FEEL any gains.

 

This is why I chose a lightweight battery in the Braille. Went from 45lb stock to 15lb.

IMO, it is a less risky choice, and much easier install than the pulley.

 

I've got the underdrive and it definitely makes a difference - not in horsepower or "pull" - like phee said, you won't really feel a horsepower difference.

The car does drive easier, though. Response time is better when I hit the gas pedal.

I've had mine for a year now and have had no problems at all.

bottom line: if you want to make your car's life easier, this mod certainly helps.

if you want to go faster, stick with PCD's and a good j-pipe.

 

Just wanted to say to the OP that I know you are new here, welcome. I've seen a few of your new threads and I just have to say; You should really should try searching the threads. There are literally 100s of threads exactly like this one. Many of the same people are going to chime in preaching the same thing. You're not really going to find a different answer. There is no use really....Yay or Nay? It will ALWAYS be both answers from different people concerning every single mod. What matters is what YOU want.

I say that only personal experience can make a real decision for you over other people's opinions. I knew EXACTLY what I want on my car and I went out and built my dream. Nobody can sway my opinion. Try things, mix it up. If you don't like it, swap it at the Black Market, chances are somebody wants that part more than you. Sure this is not a cheap hobby but if you are so worried about money you might as well leave it stock. And we all know that is boring. Have fun with the car and see what suits you. We all have our own opinions and taste.

 

Rockyfellar....Really appreciate your post and obvious opinion….but isn’t the whole point of a Forum exactly this....People to discuss things! I agree I could spend hours searching through older threads and read a lot of the same (and have) but what fun is that? It is nice to post something like this and be able to interact with people directly through it! It is also a good way to meet some great people that enjoy helping out others with what they have tried and experienced! I can gather from reading your post you are somewhat of an individualist and that is great so just keep it to yourself and don’t respond! I personally rather not just be a taker of info but also be a sharer of it, but that’s just me!

 

Not really. Most people just get pissed off and tell you to search. Most of the stuff is covered technical wise anyway. Personally I hate repeating myself...First few times its ok after that it gets annoying.

 

Let's play nice here, we are on this forum to help each other. If your only answer is going to be "search the forum" then maybe you shouldn't post in this thread. I don't see what's so difficult about copy and pasting some threads with info on them.

Yukoncole, you can PM me again if you have any more specific questions. I'd be happy to help

 

Thanks Alex we need more people like you and me on here instead of the uptight types...you said it all, we are all suppose to be on here to help one another out not bitch about something that may have been discussed once or twice before!

 

You are kidding right?
Yes, I agree that the forum is great and people sharing is what makes it thrive.
But you telling me I should create a thread for every single thought that pops in my head and expect others not to be a little annoyed?


Get outta here with that

 

I do not recall any stating that! The things posted here are things everyone chats about and loves doing to there cars! It is simply to share what are results have been, who ever said anything about posting every little though in our heads? It seems your are twisted a bit :-(

Can't we just all get along??

 

How am I twisted?
You created a thread because of the lack of researching/searching.

Don't misconstrue your laziness for anything else Jeff....

 

I don't think you'll be the one creating threads for every little thought that pops into your head at least I hope not I've seen your searching skills, so you wouldn't need to anyways

 

Man tough crowd. I am interested in this stuff too but am also some what new to this site. Cant yall give us noobs a little break?! Its not bad to start a new convo cause guess what...technology progresses so there will be more to talk about always. So have fun Rockyfeller reading all your posts over and over and over again. You da man!

 

OK guys-that's REALLY enough. The pissing match is over. The fact of the matter is that the pulleys HAVE been discussed A LOT. Use the search engine and tone it down.
