Anyone got the UR underdrive pulley's?

[Type R Positive]

Ment to be a good 10+hp gain ATW right there!

Just wait for Aaron to explain to you the pros and cons of using UD pulleys... He drilled me on it a few nights ago... Whew ...

[curik]

That cat? We should get ALN to have a word about them. He has got em in his euro

[ALN]

I'm using one now. Good gains,noticable. Works similar to flywheel make your rev lighter, produce more low end to mid range torque.
Cons, if you have upgrade audio might cause issue since alternator pulley relatively smaller than the stock one.

[aaronng]

Underdrive means your alternator spins less compared to stock. So your battery won't be charged as much. If you keep taking short trips regularly, then the battery will eventually reach 1/2 capacity and lose its ability to hold charge.

To avoid this problem, use a deep discharge battery like the Odyssey or the Optima (if they ever release a new D51R).

Cats make hp, but they don't charge your battery. You need a hamster for that.

The best mod but not the cheapest would be to use lightweight rims.

Read some USA threads where one bloke tested voltage, he still had around 14v with all the lights, stereo, aircon on at 1k, 2k and 3k rpm.

I don't see any problems other than if you had thumping stereo, or idled it for hours.

Dudes with RSX's don't seem to have any problems either?

When you are above the threshold alternator RPM, your voltage is still the same. But the charging current will be lower. Did they measure the current? If your voltage is lower than 13.5V, then your battery doesn't charge. I meant that the lower rpm of the alternator results in a lower current that causes the battery to charge slower. Each time to start your car you drain the battery by quite a bit.

BTW, stock TSX with the stock battery dies after just 30 minutes of listening to audio without the engine on.

I've been using it for 3-4 months. I got it from Tsxparts. For installation, I can't recommend you any thing since I got a workshop installed it but from what I saw, the hardest part would be installing your Crank pulley since it located below your engine.

[ZEi20T]

i hope its not located below the engine. you would hope its installed on the front of the engine :P

anyway, depending on how much room there is down there, its probably not all that hard a job to do

[ALN]

yes it is located low in the engine. I saw other 2 pullies was easy to install since you can reach it just by open the hood.
I saw the lift up my car to install the crank pulley. I really recommend you guys paying more attention when installing the crank pulley if you want to do by yourself since failure to install it properly can result in engine failure. That's from what I heard from the mechanics.

Certainly doesn't sound like a simple thing to install. :zip:

How long did the installation take and where did you get it fitted?

[ALN]

The workshop took about 35-45 minutes to install it.
I got it fitted in Racing Project but pretty much it can be done in many workshops. The hardest part is when installing the crank pulley from what I saw.

I wouldn't install it myself.I'd probably f*#k it up!!!Sounds too hard,too much swearing and bruised knuckles!!!:p

[kitbkk]

i really think getting the pulleys installed would need to be done by mechanics as it would be a very tough work to DIY as using airgun or air ratchet only would turn the pulleys as well as the bolts i think.. You would need a special tool to lock the crack pulley in place. I wouldnt touch it myself for my 2cents

I'm thinking about getting lightened flywheel.I believe it works the same way(more responsive low to mid range)but better! Has anyone done this?I'd be int. in any feedback.......Thanks.

So the pulleys don't turn and the bolts come loose as apposed to using spanners!

[ZEi20T]

wouldnt there be enough compression in an NA motor to NOT turn when you are using a torque wrench to get the crank pulley off? i can understand a low comp turbo motor turning, i could turn my SR20 by hand from the flywheel!

[Type R Positive]

Depends on how tight the bolts are!!!
Airguns and the like are great for initially cracking the bolts off the seat.

It's 43 mm wider than stock. It'll fit in a stock Euro, but it won't fit in mine as I have no clearance because of my intake.

You just need to put the car in 6th gear and get someone to press on the brakes. Your car isn't going anywhere.

Post up a pic and you'll see why. The Injen in CAI mode gives you more clearance than stock since it is just a pipe. ;)

BTW, why did you get a D75 when you could have used a D35 instead?

[ek4-guy]

has anyone seen dyno proof that these pulleys work on honda motors
because a friend of mine who is a distributor for pulley kits installed one onto his VX SS ute it took him an hour to install and he run it on his dyno before and after and his LS1 chevy made a total of 1kw extra

now my thought would be that a LS1 has over twice the power of honda motor like mine wouldnt it only yield 0.5kw

[Chris_F]

i think it has more to do with removing rotational mass? similar to a flywheel - probably wouldn't notice the effects so much on a motor with a lot of torque?

In addition to removing rotational mass, UR underdrive pulleys have a smaller crank pully and larger accessory pulleys. It alters the ratio like how a mountain bike's gear system would.

Did your friend install lightweight pulleys or underdrive pulleys? There is a difference between the two.

From what I remember, in euro/ tsx case, the UR crank pulley is the same size with the stock crank pulley only it is a lots lighter. The accesories pullies is smaller size and lighter.

hmm i see... sounds like the commodore simply had lightweight pulleys then? That's something I'd be interested in.. underdriving doesn't sound to appealing

It could be only the accesorries pulley he used. A workshop told me ,he installed accesorry pullies only to one of his customer then dyno before and after, only yield 0.5-1 kw.
I think is clearly if there is a big gain in pulley mods will come from the crank pulley replacement.

Thanks. If it's under an hour for installation then it's not that bad. Seems like an interesting mod to look at. :thumbsup:

[ZEi20T]

lightweight pulleys will barely make a difference. pulleys dont weigh much compared to say a flywheel. underdriving WILL make a difference, but with lightweight IMO you should just give me your money and let me drive the car lol

that 1kw on the commodore may not have been the pulleys doing that, 1kw could have been the difference between two consecutive runs.

From the TSX forums the guys who installed the pulleys have gained a fair bit of power and they also have dynos to prove it. I'm sure these pulleys will give more than a measly 1kw.

Lightweight pulleys will give very little power gains. You will get better acceleration, just like going to lighter rims or flywheel.

Underdrive pullies on the other hand changes the gearing of the accessories, so it will reduce parasitic losses and give you back some power.

[badthing]

Are underdrive pulleys lightweight too?

[aaronng]

Are underdrive pulleys lightweight too?
Most of them are. But most of the gains come from it being underdriven.

[ALN]

UR underdrive pulley set for euro save almost half of it's weight compare to stock one. Gains produce from the pulley come from the weight saving especially the crank pulley and a bit from pulley accecories underdrive. That's why when you use AEM or others brand accesories pulley will only give very little gain or almost unoticed so it's different to UR pulley which also include crank pulley.

Honestly, since I'm using both of lightweight flywheel and UR pulley set, I could give feedback that both basically gives improvement to acceleration. Lighweight flywheel will make rev feel much lighter than the stock one( depends on the weight of the flywheel) however the torque will be reduce a bit that's why it will feel more flat torque to entire power band. In UR pulley set case, you will rev a bit lighter and gain in low to mid range torque kicking feeling. I don't know how much kw will UR pulley produce since I haven't dyno it , but definitely won't be very little to no gain since I noticed the difference after the installation.

It's definitely noticed mods. I'm not using stock battery now since I may have mentioned before I have upgraded audio around 500-600 watt which killed my battery just 3 weeks after I installed the pulley but it's already been warned from UR before that upgraded audio close to 600 watt or more can cause problem as the alternator won't charge enough.
I'm using after market battery from autobahn (centurion) and I uninstalled my audio back to stock and running for almost 3 months since then without any problem. The belt is stock belt. I didn't experience any problem after installed the pulley other than the upgraded audio.

Do you plan on reinstalling your audio system into your car?

Also, could you take a picture of your accessory belt auto-tensioner? I want to see how much is it compensating for the UR pulley set using the stock belt.

I got them for US309 shipped from Excelerate (Acura Tsx.com). Or if you want to be hassle free, there is one on ebay for US280 + $60 shipping = US340. I know they are not gold plated or titanium cast, but hey the resale price should be good too!

Anyway is it really not safe to have front tyres wider than rears? Im talking about 245 fronts and 235 rears so it's not a huge stagger. The only reason I do this is to preserve the life of the tyres by rotating them.

Recommended replacement belt is a Gates Micro-V belt, part No:70683.

I hav spoken with Gates Australia and do not list this part in the Aust product line up as they have never brought it into Australia. You can do a one off special order with Gates Aust but it will cost you $$.

Its easier and cheaper to order it online from a motor parts supplier from the US.

I think the belt slightly longer in my logic, since the alternator slightly smaller. Curik confirm it today about the tension parts compare to his stock one so would be better to buy new belt.

not sure as i alwais love to listen to music when engine is on idle
lol

Nice findings mate:thumbsup: what magazine is that?

Yeah it would.It depends on the size of your amps.I'm running 1x4 ch.200RMS(50 per ch.)and 1x2 ch.(bridged)120RMS for sub and have no probs.although it does shorten the life of a normal battery a bit.In my last car the battery only lasted 2 yrs.

errrr so total is 320RMS only which may not enough to kill the battery.
So you got the pulley?

No,but thinking about getting them!!

[TypeG]

better think carefully first lol coz i will be quite pissed if the battery goes flat
haha

[aaronng]

The stock battery is very low on RC. So if you have an aftermarket system, you should get a battery with a higher capacity. On the downside, a higher capacity battery that is used to power a powerful system will need more recharging. And recharging capability is slightly downgraded when you use underdrive pulleys.

I only concern the recharging issue as my stock battery still run fine without the pulley

[aaronng]

Wait til Curik gets his pulleys, then he can measure the alternator voltage before and after the pulleys.

[Atjo]

I have the pictures of the UR Pulley set. It's not mine though.

I will force him to do it then

[Atjo]

Nice pics. Could you check if the alternator pulley is larger or smaller than stock?The pulley is in my office so i can't compare it, maybe mugen88 can compare it when he takes the pulley from me on friday.

[TypeG]

should as him to dyno b4 and after he install =)

[tony1234]

The stock one is smaller i think!!!

[mugen88]

I'll get a dyno done b4 and after pulley install.

Not sure when I'll get it done though.

[TypeG]

quick bastard
lol

[aaronng]

The stock one is smaller i think!!!
Then it really is underdrive. The alternator pulley should be smaller when mated to the smaller crank pulley to preserve the stock RPM ratio of the alternator.

[kitbkk]

please tell me its not gonna be worthwhile mod, please tell me its not gonna work if your planning to upgrading the sound system.
Otherwise ill have to be drinking hard-earn beer and taking shower without soap..

O acurazine, there is talk of underdrive pelleys being tested for the TSX. The alternator pulley is smaller than stock in that set to preserve charging capacity. It's supposedly cheaper too, if you trust that brand. Can't remember the brand.... will check tomorrow.

Edit: The brand is NST (NonStopTuning). They are popular for Toyota parts.
The guy who has the preproduction pulleys has booked his car in tomorrow to get before and after dynos.

In atjo pic of UR pulleys the alt.looks bigger than stock.Maybe it's my eyes!!!:confused:

Hi Tony! Nah, your eyes are fine. UR alt pulley being larger means it is underdrive. Less charging capacity. Just like a bicycle, where the front gears are the equivalent to the crank pulley and the rear gears are equivalent to the accessory pulley. The smaller the front (crank) gear, the more underdrive, and the larger the rear (accessory) gear, the more underdrive too. Ideally, the smaller underdrive crank pulley should be compensated with a smaller alternator pulley. Unfortunately, that means you'd need a shorter accessory belt.

K series Honda pulleys are not harmonically balanced. So using aftermarket pulleys should be alright. Of course, we could always wait to see if there are any reports from the TSX owners of their engine blowing up with the pulleys.

Unorothodox racing underdrive pulley set. :thumbsup:

[aaronng]

Pics of the NST pre-production pulleys are up at acurazine. The guy who's testing it has only the crank and alternator pulley, and yes it needs a shorter belt than stock. I asked if a power steering pulley would be made as well.

Hope to hav this installed in Dec sometime with some dyno tunning. In the mean time Curik might hav this installed before myself.

[TypeG]

Andrew, what piggyback or ecu u getting to dyno tune your car

[curik]

hi andrew, where did you buy the pulleys from? i bought them from excelerate but they are not here yet. they were shipped on the 10th

[TypeG]

10th Oct?
omg..... that's way too long since US ppl usually use UPS

[mugen88]

Bought from TSX Parts, I hav a Apexi AFC Neo I'm going to try out.

[curik]

Yeah I hope the pulleys will show up. Excelerate used USPS Airmail, so it might take a while...

[tony1234]

Yeah I hope the pulleys will show up. Excelerate used USPS Airmail, so it might take a while...
Did you get ins. on your delivery?You might have to make a claim.It seems a long time you've been waiting.If you paid thru paypal don't you have some recourse thru them???

[mugen88]

Didn't you get tracking details from Excelerate, a lot of support for him on the TSX Club for reliability.

Nah, he said there is no tracking number for international package. I'm sure its USPS who is at fault

[curik]

Haha I dont know, the seller didnt say so. I hope it is on its way here and not lost.

[aaronng]

USPS Airmail does not have a tracking number. Only EMS has a tracking number. Give up to 4 weeks for the pulleys to arrive.

[sodaz]

Yeah don't worry. It will eventually get here. It takes a bit of time for it to go through customs too.

[curik]

4 weeks? Are you positive, kitty? I have not experienced an airmail that takes that long before. So if the item was sent on 10/10, ill give it until 10/11? I have the customs number of the article, can I call the customs up to see where if it has been received by them?

[Atjo]

It's better to order from tsxparts.com then cause only took 1 week by air to arrive and the price is US$329.6.

[sodaz]

I have the customs number of the article, can I call the customs up to see where if it has been received by them?

Yes you can. I've done it before. Just tell them that it's a gift for a friend and that you really need to find out where it is.

I'll bet it's caught up in customs.That lot are hopeless.:(

[aaronng]

They usually want to check what is the "true" value of the pulleys and whether it exceeds $500 so that they can reap maximum GST off you.

[curik]

I wish I have bought them from TSXparts instead... Anyway Atjo, how much was shipping of the Tanabe SMH? I'm thinking of the MT

[Atjo]

I wish I have bought them from TSXparts instead... Anyway Atjo, how much was shipping of the Tanabe SMH? I'm thinking of the MTI don't know how much the shipping if only tanabe SMH. Last time i bought Tanabe SMH, injen CAI, short shifter & pulley ($699 + $238 + $45 + $299) = $1281 + shipping $293 = $1574 + 3% paypal fee $47.22 = $1621.22 = A$2203. I think if you pay with electronic transfer the fee is cheaper but i wanted to avoid confusion about the transfer fee so i just paid with paypal.

I think hengis bought skunk2 from tsxparts US$629 and he paid A1250 so you can work out how much roughly the shipping if you bought only the exhaust. I also declared the value only US$750 to avoid custom tax. They used Bax Global for the delivery and only took between 1-2 weeks, mine was delivered about 1 week.

[aaronng]

How long has it been since the pulleys were sent out?

[curik]

Excelerate said it was on the 10/10

Hmm did he send everything as one package? or he had one package for exhaust and another one for the rest?

[kitbkk]

Im still waiting for my RT cat from excelerate as well. I ordered mine on 22nd October it still hasnt arrived. He told me the cat needs to be shiped to him from the manufacturer and since he has it, it would take another 4-10 days to arrive here. Well its been 16 days since I made the order and he still hasnt recieved it damn. I think TSXparts is heaps better than excellerate. Better guy and better communication and faster shipping as well.

Have you thought about cancelling the order and buying the aussie made, world's best, super duper "Metal cat"? They are ment to be the best, highest flowing cat's in the world......

[aaronng]

If it is the highest flowing cat, then it might have the highest emissions of all cats? Even the RT cat is on the border of not meeting California emission levels.

[curik]

hmm.. metal cat costs $440.. since it is not bolt on and requires a custom fitting, whereas the RT cat is. And since the price is similar, I guess there is a point on buying the RT cat.

[Atjo]

I was told that jetspeed has a custom bolt-on metal cat that can fit in euro around $3XX fitted. So i will give them a call cause if the price is around that, me & my friend will buy from them.

I honestly don't know? Good question. What I do know is that they are fully legal here in Aust, EPA and CARB compliant, so I would assume that they are good.

Are the Yanky ones even legal here (stamped?) if you want to look at it that way?

That is quite a good price Atjo.
Well, I paid for my RT cat for $390 USD shiped. I know its quite over-priced but at the time I ordered it I had a lil bit too much beer lol. TypeG paid around $440 AUD for his metal cat, the price was included installing. Well, metal cat should be more reasonable. lol no more drunk ordering for me lol.

lol I think we are a lil bit off topic. Mugen88, after you install the pulleys can you give us some reviews both on the gain and affect on the battery charging? thanks mate

he dun have aftermarket sound system I think so he will be fine but I dun expect MUCH on that pulley even from the dyno figure in magazine.

Not sure if it is legal, but all they do here for testing is to put in an exhaust tester. So if it works properly, it should pass.

If it is carb compliant, then it should be work properly.

[aaronng]

Tony, to compensate for the smaller crank pulley, the alt. pulley has to be smaller

Yep.that's right.i got it wrong way round.:zip:

[BusterSonic12]

noob question*

so the underdrive pulley improve performance of the car?

[TypeG]

yes according to the dyno but not expect MUCH

[aaronng]

At least better gains than an intake :zip:

[TypeG]

lol
coz i think ppl expect too much from it
7hp to 12hp gain on the same dyno from the magazine

[euro77]

*noob question*
how does it improve power? is it because the pulleys are lighter, hence lighter load on the engine (similar mechanism as lighter flywheels?)?

sorry if already answered, there are so many pages to go through :(

[aaronng]

It's lighter by a little bit (same effect as flywheel), but also being underdrive, it doesn't lose as much power running the accessories.

[Pumped]

I was told that jetspeed has a custom bolt-on metal cat that can fit in euro around $3XX fitted. So i will give them a call cause if the price is around that, me & my friend will buy from them.

Will any jetspeed supply the cats already made to fit for this much?

no
all metal cat need custom job to put in
jetspeed is doing labour free as metal cat is $360 suppied in most shops

Now have a look at this! That son of a paperboy, it was actually up for first delivery on the 16th last month!! But they didnt give me any notice card whatsoever until they slipped a final notice yesterday! Thats why I thought it was not normal for an airmail to take a month. Thank God finally my pulleys have arrived. Will do install in a short time!

^^^ lol I even told Excelerate to use different shipping as I didnt want him to use USPS being afraid it would take too long like what happended to yohan(curik), then when I mentioned Yohan's name in the PM I sent him he was like where and how did you know Yohan lol..

[curik]

lol, i did. I went to racing project to install it. They have a special breaker bar that is 1m long, so if you have a breaker bar with pipe extension it would be an easy job to do. They did it in 30 mins. It feels that your car weighs a lot less with the pulleys.

can feel the torque difference, right.:D
If you read the instruction note. It' said the biggest gain will occur after few days of installation. since the ecu must adapt to its change.

Excellent mate. I'm glad you finally got your pulleys. According to the other forums, you should get even more power after a week or two. Did you notice any power issues (e.g light dimming, power steering heavier etc)?

BTW, where is this "racing project" place? 30 mins installation is awesome!

[BusterSonic12]

where did u buy the pulley from? and how much was it?

[curik]

racing project is near the intersection of maroondah hwy and springvalue rd. I am not sure of the exact location, but this is his ph no 0419663366 (Nelson). He is from HK btw. Pulleys are USS330 shipping included.

Power issues? Nothing at all. I have upgraded speakers btw, but again if you have a stereo system I would not recommend them unless if you upgrade your battery.

[sodaz]

Thanks for the reply mate. As far as i know that's not in Sydney right?

Nice pics. That's going to be my next mod. :thumbsup:

[curik]

Update! After allowing the ECU to adjust itself, I have noticed a side effect. The engine pulls harder, and revs up faster. It feels like your car has just lost its weight by about 2 adults. Also vtec crossover becomes more audible, like a mini k20a. So now I only have one problem... keeping off my foot from planting the pedal down!

[aaronng]

Haha, good stuff! :thumbsup:
I will probably go for this mod in the future. Plan to dyno your car?

Now that's the kind of side effect i can live with! :thumbsup:

I will probably go for this mod in the future. Plan to dyno your car?

Yeah I wouldnt mind a dyno.. But I will be going back in 1 week, so might have to wait till next year.

[Gerald28]

so....is this mod not suitable for cars that have stereos over 600rms??

can a larger battery help compensate the loss through the smaller alternator pulley?

[aaronng]

BTW, isn't your Injen CAI already loud? So this makes your engine louder?

Just an update, installed the UR pulley kit.

Best way to describe it as getting greater acelleration response without the heavy effort of pushing on the pedal before the pulleys.

Here are the weight differences btw stock and UR kit, there is a huge differance.

Stock alternator pulley= 275g, UR= 40g

Stock crank pulley= 2070g, UR= 250g

Stock power steering pulley= 480g, UR= 200g

IMO it has been a worthy upgrade and now looking forward to Dyno and tunning it in at the end of the week.

[euro77]

[tony1234]

I'm seriously considering getting these!!!

[sodaz]

Sweet i'm going to be ordering mine in the next couple of days.

[stephen8512]

how much is labour btw?

UR pulleys = almost 300 AUD + ? for labour?

[tony1234]

Is there anyone that sells the pulleys in Aust.or does everyone order them from US or ebay?

[mugen88]

Order from U.S, use TSXParts good pricing and reliable.

Expect installation to cost around $150-$200 for a couple of hours, not an easy job but use somone who is familiar with Honda engines.

150-200 woooo
close to putting clutch in...

Racing Project do it for less than 1 hour and can be cheaper than that. Did you call Racing Project?

I ordered the pulley for mugen88 for US$329 but together with my exhaust & intake. So i don't know how much is the price delivered for the pulley itself. Just ask TSXParts (Norm), he's friendly & helpful.

[yfin]

Can't see why Adam as the belt and accessory layout is the same for auto or MT.

[adammet04]

[mugen88]
