+15.9 whp and 10.9 ftlbs!

I've had the pulley on my car for a few months now...no probs yet (knock on wood) and I really like the extra pull it gives above 4K.
Almost pulls like my wifes VTEC Civic. Found a more noticeable result (butt-dyno) from the Crank Pulley than the Cams...but just my opinion.
I have heard that a Crank Pulley and F.I. is a big no no....

You're right about the numbers, but they list two different sets of "baseline" numbers. Look at page 98.

Also of note, look at dyno run #1 and you'll see the hesitation in print. The car takes a huge dive between 2.5k and 5 k. Looses about 10 hp and 25 ftlbs. The other baseline dyno run do not show this.

Is this a lightened pulley or a lightened/underdrive pulley??
If its a underdrive pulley you may not want it since the alternator is already underpowered you wouldnt want to slow it down and have it put out even less power..

 

[SuperSpud]

well a few ppl from this board have them and they have said they have had no problems at all.. just the lights diming a little when they have their stereo up loud...

well I have to throw in my 2-cents... I work at a ford dealer and I see pulley's all the time and more than 8 times out of 10, pulleys do more harm then good. For instance the light dimming is due to the fact that there is less resistance becuse that pulley is lighter and smalled in diameter. Your ac does'nt spin as much, same with your Power steering and alternator. Over time when you have your stereo up it will damage the battery as well as the alternator, but you never know. Most cars have had them on their for more than a year so just watch out.
Sorry for the long post

My bf has a pulley on his 99 Cougar V6 and hasnt had a single prob. On most cars it wont be a prob .. its the big V8s with lumpy cams that shake the hell outta the car. The only downside is that the alternator spins slower and at idle your lights dim more with the system -- start driving and your fine again. His system had the stock battery and alternator pushing over 2000 watts RATED power -- so you know the actual was way over that --- still no probs.

I had them on my nissan for a couple of years. sr20de. I used to rev the snot out of that little 2.0 up to 8k and I never had any problems with them. I believe the crank is balance on the nissan as well as on the pully. does the protege have this?

yes it is a balanced steel crank but the issue is with the oil pump.
without the dampener it will self distruct if revved too high and thru unwanted harmonics

WHat about this??
Water Pump / Alternator Pulley Set

Fits 2.0L motors. Because of their 15% reduced diameter and lightweight, energy normally used to turn the heavy stock pulley is now used to turn your drive wheels! In addition, the lightweight aluminum Indigo GT Pulleys are a perfect choice for road racing ,drag racing and autocross due the reduction of water pump cavitation. Horsepower gains of 2-3 HP normally , but can vary widely depending on what has been done to the vehicle.

Part Number PR-12165

i have been thinking about getting that... will it help free up some power at all or what?

The stock pulley is weighted and a certain size for a reason. Don't do it.

mazda motors is balanced at o CERO dont need harmonic balance

my msp have pully 8 months and dont have any problem

att irr

The Unorthodox Pulleys wont always cause damage due to the absence of the harmonic damper but it's likely to happen and if it happens to you then tough luck. If you get it and it causes damage then put the stock ones back on, take it to the dealer and get it fixed through warranty.
I had a 97 Eclipse GST and I know the Unorthodox Pulleys use to screw them up every now and then but Buschur Racing made a set of underdrive pulleys for it that gave the same increase in performance but their pulleys were made with the harmonic dampers.....so wait a little and see if a company out there will do the same for the MSPs.

There was a write up in I think SCC (I want to say Dave Coleman wrote it) a while back. I don't remember the conclusion of pulleys on cars. Might be worth trying to find.

And a UDP (underdrive pulley) will be fine on some motors. The Mazda B-series motors have had problems due to them, tearing up oil pumps. As where the Mazda F-series (used for 10 years by Mazda in the MX-6, Probe, and 626) has not shown problems with an UDP.

It's ignorance to say "it is bad, don't do it, it will hurt the motor, etc" Because different engines are affected differently. I've had one on my Mazda K-series (KL_ZE) for a year and a half with no issues. I have never heard of anyone having problems with K-series motors either.

I think you guys should really spend more research time on Probetalk.com or mx6.com everything has been done to these motors.... There's nothing new with them.

The only issue with a UDP on the MSP motor would be the stereo. I called and asked about this though. They said there is NO issue with the stereo in that car. There only would be if you had EVERYTHING going or added amps. They don't reduce the size of the pulley more than 20% so there are not problems with power accessories.
