so i just bought an unorthodox racing underdrive crank pulley and new belt to go with it. i have ran these on hondas in the past without problem, but have never ran one on the j-series. i have read all of the threads i can find on the subject, but am not sure i want to put it on. for those of you that run one, did you notice an improvement. i dont have much invested in the part, so it wont break my heart if i decide not to use it. how well did your a/c work at idle. any other adverse affects.

thanks
ryan

 

used on my 09 for 2 years, no obvious adverse affects. I installed mine along with a Short Ram so I can't say if it helped or not as I secretly have a feeling that the SRI kills power at idle and gives more on the go. Can't quantify UR pulley alone.

 

thanks for the input. i guess i will run it and see if i think it helps. i havent had my car very long so it might make it harder to tell if it has done any good. anyone else have any input

 

still not sure what i should do. should i run it or get the oem size.

 

Touge claimed no adverse affects from installing the UR pulley, but then again, he was also selling it so I take it with a grain of salt. I know there are at least 10 people here who have it and I have only heard of one issue. From the recount, it seems that it was more of a bad install than a problem with the pulley. I don't think you will have issues with your A/C at idle or other electronics as long as you don't add a bunch of other systems. One reason I am staying away from it is b/c of my 2000W amp pushing two 12" subs. Knowing the RL already sucks power from the charging system, I didn't want to push it too hard. I would say the pulley puts the car right on the functional side of the brink of the charging system limitations.

 

im not sure if thats where i want to be. i might just sell it and get the stock sized pulley. i appreciate your post. in the end it will help me decide what i want to do.

 

no point in installing a pulley unless you take full advantage, meaning lower weight and underdrive. I had my Acura dealer install it with a proper size belt to make sure there aren't any surprises, it cost me an arm and a leg but guess what, still running strong 2 years later.

 

i know what you are saying. i ran the pulley set on my 95 prelude vtec and never had a problem. i had full intentions of running this crank pulley until i started reading how the rl as hard on electrical things to start with. when i get it i probably wont be able to resist putting it on.

 

pulley difinetely works fine without an upgraded sound system I can tell you that much.

for 05-08 the weight savings is quite significant. I think 09+ pulley is much lighter.

 

pulley came in today. looks really good.
