What do they do? How much HP/Torque gain in a TL-S? Which brand is best for the TL-S?

 

anybody? i was thinking of getting pulleys too

brand new AEM true-power pulley kit, blue anodized! maybe 500 miles. i can't use it with my high output alternator $100.00 including shipping! kman

 

kman..... im interested in them--- did u notice a gain... also how much would it be to install that... and would it be less if i pick them up from u... im in miami

I have the same pulleys in mah car. In my opinion you barely notice a gain. Maybe a little faster on throttle response but other than that its really nothing much. I paid 75 to get them installed

The pulleys are basically smaller and lighter. They come with new belts and free up power from your car to give it horsepower...

 

thanks edroe- do u think they are worth it?

According to people I've talked to that have AEM pulleys...there was very minimal gain...in the vincity of 1-2hp. They did mention that with the pulleys...you do get to VTEC much quicker. Unorthodox Racing is developing a pullies also that includes the main thing that AEM is lacking...the Crank pulley. This is where the most hp can be realized. Unorthodox claims a 10hp increase using their pulley system. If you go to Acura-cl.com, there are some people testing out the Unorthodox right now, you should be able to get an idea of which one you would like. AEM is cheaper than Unorthodox due to the missing component. Also keep in mind that to get these hp, you lose certain "features" in other areas. You lose a bit of light steering, the alternator maybe weaker and can not handle an aftermarket system, and I think there were a few more things that you might lose. I think most people do it more for the looks than performance gain. A CAI can achieve you more hp and a better sound for about double the price. Correct me if I'm wrong...

I still don't understand how they work. Please don't make me have to go to "womanmotorist.com" to find out how. Thanks for the input guys but do you have a more clear cut explanation of how they work? And what do they have to do with the car's sound?

 

As far as sound...they won't make any...atleast they weren't design too anyways. Here is what one site posted about them:
Power Gains
Unorthodox Racing pulleys can provide gains of 5 to 12 HP and 4 to 8 ft.-lbs. on normally aspirated engines and 8 to 16 HP and 8 to 18 ft.-lbs. on forced induction engines. These are average gains. Gains as high as 37 HP and 45 ft.-lbs. have been realized on modified forced induction engines. These gains are obtained in two ways. First, and most important, is the weight loss. An average of 2.7 HP is gained from every pound lost off the crank shaft. 85% of our gains are from weight loss. The rest of the gains are from underdriving, which accounts for about 15% of the total gains. Unorthodox Racing does not push underdriving for two main reasons. Our main reason is to keep charging systems, air conditioning, power steering, and water pumps moving fast enough for every day driving. Second, not much horsepower is gained from extreme underdriving. All of our underdriving is done with the crank pulley, not the accessory pulleys. This is done so maximum weight loss can be achieved at the crank where most of the horsepower gains are found. Courtesy of http://www.ptuning.com/html/Item-Des...9&ModelDesc=CL

Here is what some people felt about the pulleys:

well does Unorthodox provide Tl any pulleys? I can't see any out there. Plus is that mean AEM's pulleys are not good to buy for gain power, but for outlook ?

 

The most hp/tq gain is realized from the Crank pulley. The AEM kit does NOT have the crank pulley at this time. That is why AEM's kit is selling for much cheaper than UR's. I do not know if UR makes the pulley for the TL, but I would venture to believe that the Type S engines are identical and should work...try emailing them.

 

K man where did u order ur high output alternator, i'm looking into upgrading my system and i'm probably going to need to do that. Also does anyone know if these Unorthadox Racing pullies will work with a high output alternator? thanx. peace.

for 130 + about 70 for install.........a 200$ mod that makes it look better and adds a couple hp is worth it.........we're talking about a honda here.......ur not gonna get like 30+ hp from one mod like a supra tt or somethin

 

How they work is like this...

Horsepower is at the crank. From the crank, it goes to the transmission AND to power certain accessories, such as power steering, water pump, altenator, and A/C. Smaller pullies take less effort to make one complete revolution as do their bigger counterparts. This is how these pulley sets "free up" HP. They don't create any more HP, but instead just reallocate it to the transmission instead of the accessories. I've even seen electric water pumps so that even more HP could be saved from belt driven accessories.

They won't affect the sound of your car. They will cost you certain accessories, such as low altenator output. When you use your wipers, headlights, A/C, and stereo all at the same time, like on a hot rainy night, things might not work as they should because they will be starved for power- power that was supposed to be there but is no longer because the smaller pulley on the altenator doesn't allow it to make as much electricity as it would using a normal pulley.

 

Damn good post Johnnyb! That's what I wanted to know. The UR pulleys do sound interesting
