Hey guys, just wondering if you think that there would be a huge difference (or any at all) between this pulley and the UR one. They are made from the EXACT same stuff so I wasn't sure.

40 views with no replies? somebody has to have had some experience with these lol

 

i would assume that few have had both, but i am interested in knowing if someone has and how they differ....

 

Id rather stick to UR, I know they calibrate and test the equip... thats a plus... ive never heard of the other company....therefore i dont trust it.... ebay is a bad way for people to get scammed and you really dont know what your getting....i know UR uses the best aluminum for this application and theres really no deviation in quality... the only deviation the can get away with, is a small blemish that wont hurt the quality or performance of the pulley and nothing else.

 

thats what I was thinking^ I just wanted to see if it would be worth the extra $40 to get ur. but I guess it would be since I've never heard of anybody having any problems with them!

oh and thanks for the reply tripnbeats

 

"07-08 Acura TL Type S 3.5L SOHC 24V FWD Auto,Manual UA6 J32A3"

lol they didnt bother to change the last part x_X

You will defiantly see a gain with this mod.

15+ Horsepower Gains!"

eh seems a bit sketchy imo. maybe to the other cars listed but i dont think its that drastic of a gain for our cars xP

 

yea the gain is insane....and then the computer calibrates itself and it feels normal again... id say like 10 HP max to the wheels.

 

10hp gain? Is this for the stock sized pulley or the underdrive?

I'd prefer to stay stock size. thx.

 

Changing the pulley has no impact on the computer as there is no change to the fuel air mixture.

 

bro if the motor revs faster the computer picks up on it and adjusts accordingly

 

true^

 

it does not add horsepower at all. it only frees more of it up. probably 8-10%

 

I highly doubt you free up 10hp.. Anywhere on the powerband..

 

dude ur freeing up a lot of weight on rotation... anyone whos done the mod can tell u....the stock pulley is around 25-30 lbs or a lil more and the UR one weighs like not even a pound....ur freeing up 10hp trust me.....but after the computer picks up the crank position sensor moving faster then it slows it down and the hp balances and probably lowers but the initial power before the computer adjusts is crazy.

and greco u wanna tell me what the difference between freeing up and adding Hp is?! same shit as adding a CAI its freeing up HP or an exhaust its freeing up HP.......precat deletes freeing up HP....ADDING FREEING (synonyms) thanks

 

Freeing up - The power produced by the engine is no longer used to power a parasitic item on the engine (crank pulley)

Adding power - when more air/fuel are introduced into the cylinder thus creating/adding more power (this can be done by opening up the intake or exhaust side).

As for the computer adjusting for crank position due to weight. I have to disagree. Computer will adjust time for air/fuel mixtures and retard or advance timing based on that. It will also adjust your idle due to the faster rev on start up. But it will not decrease the amount of power produced due to a lighter weight pulley being on it. The computer could care less.

It would only adjust the timing if began to knock. Crank position is not going to change in regards to cam timing, thus the computer does not care that it revs faster.

As for not feeling the power anymore, that is because you get used to it, not the car adjusting for it. This can be seen in the fuel economy. I have had mine on the car for about a month and I put 60+ miles a day on the car. My mpg has gone up 2-3 mpg and has remained there.

I hope this answers some of the questions.

 

i dunno man...im saying what the tech said at acura who installed it.... he said the cps will adjust and the sensors will pick up on everything...because the tps has to be at a certain position through out the power band..... so if the load on the tps is10 % and the cranks spinning too quick it'll retard accordingly.

 

Would this Modification Void the vehicle warranty? if not what would the dealer charge for the install?

 

Your getting a little excited trip. :lol:

The stock crank pulley (crank pulley only, not the full set) weighs ~9 lbs; the UR Stock sized pulley weighs ~1 lb.

Still a BIG difference in rotational mass. BIG difference. I'd kill to get that kind of weight savings on wheels.

Pulley and J-pipe are probably the two most easily noticable mods I've done to the car.


.

 

I would like to correct the weight issue. The stock pulley weighs 7.8lbs!.

 

so why is the UR pulley so much ligher? Is it not as durable? Will it not last as long? I am looking for any potential downsides before I jump on this mod. I want my TLS to last 10+ years! thanks.

 

Guys;

the only one listed on their website is the underdrive sized one. Where do I get a stock sized pulley and what is the part#?

http://www.unorthodoxracing.com/Item...e=27&Model=171

 

UR is made from (iirc) Billet Aluminium - light & strong.

OE is made from cast iron/steel - heavy & strong.


Check with Josh at www.excelerateperformance.com or "Excelerate" via PM for availability and cost.

 

bearcat;

I just spoke to someone at Unorthodox Racing. He said they no longer make the stock sized pulley for the TL but you can get it from Excelerate and others. The part # is 020611412.

Excelerate website has it listed for the RL but has the undersized one for the TL. Weird?

I called my Acura dealer and asked if they could install it. They said they could but it would void the warranty to anything that is powered off that pulley system (ie. HVAC, stereo, etc).

I once modded my exhaust on my Alero and my dealer did the same crap to me afterwards and wouldn't fix stuff that clearly wasn't exhaust related.

I have 2 options at this point:
1. have a non Acura mechanic do this mod for me and hope Acura never notices
2. wait till my warranty is up in 2 years

 

Don't get that ebay one. It looks cheap. Think about it, it's an engine component. Go with the UR one, it is tried and tested and I have never heard 1 complaint. High quality just for a lil more.

 

OMG the Acura dealer claims its a 4hr job since its the pulley that drives the motor and is an enormous job labor wise. What pulley are we talking about here? I obviously won't have Acura do this!

 

Is this true? I was waiting to get mine until later because I just spent a boatload of money on other parts...
Say it isn't so!!

 

With a lift, air tools (for lugs, etc), the OE PUlley removal tool, etc - 1 hour. Tops.

If it were a warranty replacement (OE for OE) I doubt corporate would give 'em more than 30 minutes flat rate.

 

Bearcat I agree but they are obviously trying to rip me off.

What type of pulley is this? They weren't sure if it was the main pulley for the engine or not.

 

Yes, it is the "main" aka crankshaft pulley.

 

Do you know the OEM part# so I can call another Acura dealer and get a quote from them? I may try a local mechanic as well.

From my understanding, you just need the following 3 items:
1. Lift (goes without saying)
2. 3/4in Impact Gun to remove lugs
3. Torque Wrench to put the new pully back on

As long as any mechanic has these 3 items at their disposal and follows the supplied instructions that comes with the pulley, it should be fine.

Please correct me if I am mistaken. thx.

Tools: MUST have the Honda Crankshaft Pulley Removal Tool; otherwise find somewhere else ().

Read this thread for a "How To". That way you'll know if you mechanic is blowing smoke up your skirt.

LOL how much more evidence do we need that we should not trust stealers??

1-2HRS!

 

yea if I do end up buying this upgrade I'll definitely go with the UR one. and does anybody know of any Honda specific shops in NC? thanks!

 

lol i dunno anymore, that thing feels like its 100lbs ill weigh it....its def not 7.8lbs that thing has weight to it.

 

Where in NC?

There are a few in Charlotte. HondaWorks seems to be the one most referenced. There is also one on South Blvd around Woodlawn; next to Buffalo Tire.

I haven't used either, since I never have enough money for parts AND installation.

without a lift, me mglax and timeless did the pulley install in 45 minutes. from start to finish

 

All you have to do is weigh it on an electronic scale, like I did!. It's actually 7lbs 14oz.

 

oh really??? i was gonna use a flux capacitor to weight it.

 

I didn't speecify where because I would be willing to drive a fairly far distance to find a good shop I can trust. But I'll definitely check those two out...thanks!

and lol at that^ post

 

This is the link for the UR Ultra Sc stock diameter pulley:

http://store.excelerateperformance.c.../i-220260.aspx

It fits the TL 04-08 (ALL) and RL and MDX. We will probably be the only dealer carrying these in a few months once everyone else has sold off their inventory.
