I'm gonna have to go with Baron on this one, has anybody considered applying an overdrive pulley for the AC compressor? Some people like to go fast, while others like to enjoy driving... Can such a pulley exist?

Any good machine shop should be able to do it for you, but it won't be cheap.

why dont you do the cooling fan mod instead - people have said it really helps the AC.

Okay folks, I got a wild hair and put this thing on last night. Install went fine. About an hour from box opening to first crank with it on. No problems with the install, thanks to this thread. The only thing I would add is loosening the bottom 17mm bolt on the alternator to make the movement of it easier. Everything fits well, flush, lines up, etc. Things are great, looks good, no belt slip, about .20 inch of play in the belt tension. However (but of course) at idle, no drama dash is normal. Driving around and at speed (pick a speed) I have a flashing check engine light. What gives?? Do I have to reset something? Other that that, It runs like a bat out of hell. Thanks in advance.

Put your key in the ignition, turn to the on position (not starting the car), then step on the brake pedal 20 times really fast. Keep your eye on the oil gauge, and when it goes right and then back left, your done.

This will reset your computer's shaft calibration and will allow it to re-calibrate itself to the new pulley. This happens on some cars.

Thanks! I'll give it a whirl and report back.

Phlash--you will like this mod

LOL< wrapping the frosty pipe BS, Mazda must really be stupid to not do anything so obvious :rolleyes:

if that doesnt do it, try unplugging battery then doing that... that's what I ended up having to do.

FYI - I did the brake pedal reset which seemed to work until I got on it getting up to highway speeds (honest officer). Same flashing CEL. I made a phone call to a friend that suggested the battery disconnect also. Got home, disconnected the battery and let it sit during dinner. I reconnected, did all the brake, steering wheel, and ODO resets, tightened the belts a little more and all is good. Thanks everyone for your help. Now on to Scott's cooling mod.....

Phlash--hold on the cooling mod until you get your recall done.

K........are you seeing that much difference?

Has anyone here done the AP pulley on an AUTO ? Any issues or cel ? Anyone felt a diff ? Cheers!!!

I havnt done it on AT or heard about it being done, but I assume the CEL would come on for the same reason, but should be able to fix the same way so it isnt a problem.

i had my AP pulley installed a few weeks ago and did get a CEL after i hit 6k rpm when reving to test it out post-installation. clearing NVRAM and KRAM didn't work so i had to disconnect the battery and the CEL hasn't returned.

after a few autoxs with it (and RB intake + duct) i can attest that 1st gear and the middle of 2nd gear is definitely more zippy which is quite a welcome change. =)

Does yours happen to be an Auto Transmission?

nope, manual. sorry i didn't specify.

Cheers & thanks for your speedy reply. It seems that most people here had the pulley done on a manual, no Autos..... :Freak_ani

What's the deal here. I installed in, took forever to get the ac belt on but the alternator slipped right on. There was a great deal of play in the alt belt but went away once I started it and after much high pitched squeaking and squealing. Are the belts not lined up right or something? Also, have a flashing cel then a constant one. BUt, its just the computer not the actual engine right guys? I did the brake thing and it cleared it i think. But right when I start driving, the squeak eventually goes away, and a cel came on. Im gonn go try and line up belts more.

For the sqeaking and squealing it may be that the belt is not tight enough and is slipping. For the cel, the light shouldn't come on with just the pullies unless you have a midpipe.

yeah, its just the computer.

make sure that when the engine is on the pulley isn't wobbling at all. There may be some dirt or debris behind the pulley causing an incorrect alignment. If it isn't wobbling in place then I wouldnt worry about it.

Make sure the belts are tight and if there is squeaking tighten the belts. There should be no more than 1/2 an inch of play when you try and pull on the belt when it is in place.

If the squeak is fixed then just leave your neg battery terminal unplugged for the night and the cel should reset itself, just do the 20x brake pedal pump and the ODO holddown reset when you restart it.

^^^ Thanks, the squeak went away after a day or so and also when it was squeaking it stopped quickly after the engine started to warm up. The belt has also gotten much tighter and is now is good and tight like the a/c belt. Unfortunatly, I shredded the small bolt below the long 3-4 inch screw for the alternator. Gonna have to get Mazda to order that. BUT, I am very pleased with the results. Once the belt tightened up, my butt felt a difference, mainly in the 4-5.5 region, which is exactly what I wanted. I want as much of that low end beefed up as possible. Revs quicker but I haven't noticed a huge difference. Just installed the axial flow ss too. The two go great together.

Hey guys I am considering getting these pulleys but I have one concern... To reset the computer I would have to unplug the battery for a while which would be fine except that when my computer looses power I have to tow it back to mazda to get my security keys reprogrammed (I have an 05). Is there any way around this? I am asking because I was helping a friend put on some mods on my car before and when we hooked the battery back up to the car all the lights would come on but would not crank. Thats when I found out from my dealer that they have to reprogram everything. Thank god mazda roadside assistance is free..

If you are carefull not to dislodge the crank angle plate you will not need to reset the ECU .
If you do dislodge it there is a proceedure to reset without disconnecting the batt.
Can't remember exactly what it is - search "ECU reset" .

Just installed pulleys last night and I got the cel... I did the ecu reset and then tried iit aftrer disconnecting the battery... still getting a cel..... how do you do the odo reset? Also once I'm done pumping the brakes do I just turn off the car and start it or what? Thanks in advance

You need to do a full PCM reset with a scan tool, the in-car reset procedure is not enough

I installed mine this weekend. During the installation I had the battery fully disconnected, why I don't know. Once I took it out for a test drive it was fine until I redlined it got a cel :( I did the brake reset put the ignition to off then started her up and it went away :D: I have redlined a few times since with no issues. Did you make sure the oil meter went half way? Also make sure that gear looking think behind the pulley is not wobbling. Good luck

When I tightened the screws for the pulley I set them at 20 FT/Ibs. 12 seemed to little, they did not snap or anything. Is this OK?

After I put my pulley on I got the CEL but the reset worked fine I also disconneted the battery. Every once and a while the CEL will flash with RPM's above 8k and this only started since the pulley but I love it and think it works great.

Just don't tighten it when the bolt is hot. I made the dumb mistake of doign this and shreded the bolt while tightening it.

i got the cell gone... i did the 20 brake pump after disconnecting it but the light stayed on.. drove around a little today and just vanished!

then it reset itself, the in-car method will not reset everything in the PCM

sometimes mine had the cell above the 8000mark also, I found that the triggerwheel was not in the right placement and it did this, adjusted it tightened down, and it went away

I guess I'm luck cause that's exactly what I did but luckily nothing bad happened. Next time I check they are still torqued properly I will wait until they cool. Thanx

Well I opened my mouth to soon. I decided to take them off and put thread lock. In the process of putting them back on I sripped 2 of them :spank: lukily one striped after it reached the proper torque. The second one stripped right before it reached full torque. Now I have three perfectly torqued bolts one of which is stripped and one that is somewhat torqued and also stripped. Do you think I'll be OK?

pulleys have been on for a few days. i deffinately think they help. driving my car in general feels so much better now. i feel like it accelerates to 4k faster (i shift at 4k for daily driving) might be in my head but oh well.. definately think this is a worthwhile mod. i would reccomend them. on top of that installing was not hard at all and was actaully fun. (cuz i dont work on my car much since im not car inclined..)

yea i got mine on monday...i plan on doing the install saturday afternoon....i can't wait.

from where khan motorsports?

Yes Sir

just installed mine and got the flashing cel and then solid cel when red lining. I'm going to do the full PCM Reset and see what happens.

last tank i got 12mpg.... and this tank i got 17.... could this be the ecu learning the pullies or something else? my driving did not change, and if so did not realatively change by 5mpg........

if you disconnected the battery or reset the ECU - it may account for the low mpg on the first tank.

My agency pulley arrived about an hour ago so decided to take some pictures and post them since everyone loves pictures ^.^ My apologies for poor image quality as it was taken with my camera phone.

In case your wondering about the size of the pulley, a regular CD matches the top diameter perfectly.

Cant wait to get it bolted into the car, hope it works as great on the 6spd auto as it does on the MT.

Got mine yesterday. Tried installing it without a 5mm allen socket, and failed miserably. Once I had one, finished up easily. Had to do the full battery disconnect, but I just disconnected the negative terminal on the battery, put the key in the ignition, and set it to ON for a couple of seconds (obviously nothing happened), reconnected the battery and fired it up. The blinking CEL that i had from trying the pulley without reseting was gone. Went for a quick ride, and after no CEL, started paying attention to any gains. Noticed a little pickup between 3-6k RPM, nothing earth shattering, but noticeable. Not too shabby, worth the $150.

Yeah I would have to say that the gains are between 3-6k, but the tach needle definitely goes up faster. Smooth idle, HID headlights works fine, AC sucks but then again always has hehe (the AC in my RSX was colder and had higher cfm), and stock radio works fine. After I got everything installed, did the steering wheel thing to reset the DSC system and tried to do the brake reset but failed, thought i was doing something wrong so came back to read the thread and just turned out I wasnt pumping the brakes fast enough. After a successful brake reset, took it out for another spin and the CEL went alway.

Definitely worth the $120 or so dollars and the arm full of small scratches from working in the tight confines of the engine.

Sounds like everone likes the AP pulley. Anyone have the Unorthdox pulley?

Does the unorthodox pulley set come with the same kind of pulley agency power sells?

no, the pulley sets are different. The Agency Power is more underdriven, therefore giving you more effect. The general consensus is that only the Agency Power and the SpeedSource pullies work well.

i tried doing a search and couldnt find any online retailers that sell the speedsource pulleys

just got my AP pulley from www.vividracing.com for like $160 shipped. Cheapest price around untill i noticed the group buy by khan motorsport but oh well. The pulley, belts, and hardware are very well made and look great.
