I just put my AEM pullies on about 3 days ago and ever since then when i floor it and the transmission switches from 1st gear to 2nd (by the way its a AT, LX) i hear a kinda screaching noise. And it only does it between 1st and 2nd and only when i floor it. so what i was wondering is has anyone else had this problem and is there something i can do about it? BTW i've checked all the bolts and everything and they are all tight and the belts are also tight.

So does it sound like a belt slipping? It might be the torque the engine is producing between the 1st and 2nd shift that does it. Maybe the other shifts aren't as aggressive. Since its just after a pulley install, I'm gonna go ahead and say its either the pulley or the belt. But you probably knew that already. Can you try and tighten the belt anymore?? Maybe its just not tight enough. You might also wanna check to see if the belt is glazed at all from slipping. Or, for a few bucks try a new belt... Hope I helped.

i dont buy pullys and never will. I DONT think they are a good investment for the price vs power gain they you get from them. Plus I have seen what they will do to your engine, and it isnt pritty.

Is your A/C on when your hear the sound? Also, is it when you have the car at higher rpms? If so, then it's just your belt slipping for a split-second. I had the same problem. I talked to my mechanic, and he said that it's normal. He said he could tighten it up more and make the sound go away, but he said he wouldn't recommend it. He said the reason he doesn't recommend tightening it up too much, is that it makes the rest of the engine work harder and wear down other parts faster (like your water pump). He said it's not causing a problem, and that it's common with people who get new pullies.

Have you ever researched pulleys? Obviously not.
I have a CAI, and the AEM tru power pulleys. The gain with the pulleys was QUITE noticable. Not only that, but I've noticed no difference in the A/C at all. Pulleys are as common as exhausts, but they're actually more useful. They yield gains all throughout the RPM's, not just at higher rpm's.


To answer the original question: it might be that your belts are slipping. did you install it yourself? You might want to take it to a shop, and see if everything is lined up ok. If you got it done at a shop, take it back, and b*tchslap them.

yes i have researched pullys before, infact many of times. Yes you get a gain, but for the price of them is not worth it at all. I know what I am talking about, I have been working on Hondas for years. As for problems you will get with them? Not at first, but after many thousands of miles and year later you WILL have engine problems. Try reading a real tech board for honda's, for example, honda-tech.com

I have read plenty of threads on honda-tech.com concerning pullies. From what I have seen, the big consensus is that alot of people don't recommend replacing the crank pulley. As far as AEM pulleys are concerned, they only replace the alternator and power steering ones. It seems like everyone has a differing opinion on the pulley issue. My question though is, where's the proof? Just because your engine broke down after you put aftermarket pullies on there, does that necessarily mean it was the pullies. There are alot of other factors to consider like the driver of the car, how hard the car is driven, driving conditions, age of the engine, etc. It's also possible that one guys engine was poorly manufactured, while someone elses is fine. You know, like a lemon. I also noticed that most respones saying to not get the pullies said just that. They didn't explain why, they just said bad idea. Why is that, because their friend told them it was bad or something along those lines? I've also heard stories of people driving thousands of miles and several years not having any problems with aftermarket pullies. How does one explain that if they are so terrible? I personally have had my pullies (AEM) on for about 5000 miles now and have not experienced any problems. We'll just have to wait and time will tell.

What?!?!?!

We can stop the conversation right there. It's obvious that you are NOT as well educated as you say you are.

My pulleys were $125 less than my cold air intake. The dyno'd horsepower difference with the pulleys is (on average) 10HP. The dyno'd horsepower difference with the CAI is (on average) 6HP. The big difference is that pulleys are all throughout the powerband, whereas the CAI is only when you're driving it like you stole it.

And you say you've been working with honda's for years??? were you checking the tire pressure this entire time? this isn't just a honda thing, buddy, this is an everyday-realworld-thing.

yikes.

I hope my car is never serviced by someone with your level of 'experience'.

I have pulley and i definately can feel the difference....
if you don't know..don't post...

Just wanted to say thanx for all the help, i had a mechanic do it so i'll probably go ask him whats up with it, and as for too much cost for not enough HP gain, i paid 160 for my pullies and in my opinion and to me 160 is well worth it for 10 x-tra HP. again i appreciate all the help

Hey guys, Im having my friend who knos quite a bit about Honda engines to put it on. Im gonna be watchin over, I hear it takes a few hours? Who's done it before, how long does it take and is there any pointers?

Hey, Civic junky where did you get your pulley's from? Is it 160 Canadian for them. I am also interested in them and the cheapest I found them for was 125U.S. I have a 2 door coupe si

Thanks,

Joe

Yes, you will feel somthing, but its not work the 100+ bucks for it. Im not saying you wont see anything, but you will see somthing. As for 10+ HP to the person who claims it on a dyno. lets see some proof? Lets see the dyno slip. I will put my entire work paycheck on the line if someone can get 5 or more HP out of it. That day will never happen......

End of Flame...

maybe it's not 5 hp..but there's at least something..
and u know gain as much as possible out of our civic.
cause our civic isn't fast...if you wanna make it fast...you gotta paid..

Wouldnt the pulley be comparable to an intake system in terms of price and gain?? Can you, bhaz413, please provide some proof as to why the pulleys are bad in the long run? Don't mean to flame or hate...just want to be a little more educated.

hey all motor, I got them from my local customizing place, and that is 160 U.S. and that was a deal compared to what they charge everyone else, but i'm sure you can find them for cheap as hell off the internet if you check the right places. and another tip is whenever you get them open the box right away and make sure they look right, because the first time I ordered them, AEM sent me the wrong ones and i had to send them back and they still didn't send me the right belts so i had to go out and buy new ones because i didn't want to mess with them anymore. and the installation took right at an hour, basically because it was done by a mechanic.

I would really like to know why people think replacing the alternator pulley and power sterring pulley is bad? Bad long term effects? Well, first off, you spinning both accessories slower, which means less wear and tear on them over a long period of time. Plain and simple! Also, the pulleys themselves weigh less and again it's easier on your accessories. I can't believe people try to contest this.

As for making a difference, I think they did but not really in powerwise. I find my engine-breaking is a lot less and it takes longer to slow down. Also, the throttle response is better, I like the way it revs now. I think the gain is best felt about 3K-4K rpm. The pullies make a noteciable difference but they really don't make the car any faster. I've done my quarter mile time and 0-60 time and there wasn't any significant change.

Now, to answer the original question: My belt did squeek like yours. I ended up tighting the alternator belt a bit more and the problem went away. I noticed that it squeeked during the upshift from 1st to 2nd and when I also turned my a/c on during the higher rpms. Any kind of squeeking belt is not a good situation. So, make sure you tighten it just enough until it goes away. Don't overkill on the tension though.

I think a lot of people voice their own opinions about pullies and they don't even have them. I really like the one about the harmonic balancer on the crankpulley and installing a new crankpulley is bad. Do our cars have one? No, now, where is the harm in replacing the crank pulley then?

Now, to answer Sleeper012 questions - it took me 3 hours to install. It wasn't bad but you need the right tools and patience. I will be working on a DIY for the install soon enough. PM me and I can give you some hints about the install.

fast and 7th gens dont go togather. save your money for internal engine upgrades and a turbo when they finally come out.

the 7thgen EX can be fast being all motor, it's just nobody makes cams yet. Now, what is your definition of fast? 0-60 under 7 seconds?
