Would you like to pickup another 6-8 horsepower and torque at the wheels in your FIAT 500 Turbo/ ABARTH?

Would you like to have an improved throttle response, and a LOT more fun driving?

If so, this is a great bolt on item for you!

MPx has spent nearly 6 months of testing, revising, testing and revising further to make this piece the perfect addition to your 500T/ ABARTH. MPx has driven thousands of miles testing this part on an ABARTH. Thousands of miles have been driven with this item to not only verify performance gains, but also reliability. Seven different prototypes were tested before the final version was picked and put in to production to make sure that you have the absolute perfect pulley kit.

Here are the facts as provided by MPx:

The stock pulley weighs in at 3.35 lbs. In comparison the MPx lightweight underdrive pulley weighs in at 1.8 lbs. Saving nearly 1.6 lbs of sprung mass off of the crankshaft allows for a quicker revving engine, and less power loss spinning dead weight.

By the use of this kit MPx was able to underdrive accesories by 20% without affecting the AC and Alternator. This means less power is robbed from the crankshaft for the AC and Alternator. At the same time they still function normally. Cold AC, Normal Alternator Performance and no Check Engine Lights!

MPx gained solid horsepower and torque across the entire RPM Range, not just power up top, or on bottom. This makes a difference you can feel.
This Pulley Kit is consists of an Outer Billet Pulley, Tone Wheel, Longer Crank Pulley Bolts and a new Gates Belt.

When changing the pulleys out, the 1.4L has an allignment guide pin with offset mounting holes that will make it impossible to install incorrectly. Installation is not difficult and any good mechanic, or home mechanic should be able to install this in under an hour with basic hand tools all from within the passenger side wheel well.
This entire kit is manufactured in USA.
The Outer Aluminum Pulley is hard anodized for long life and great looks. A Trigger Wheel is made out of steel and is zinc coated. A brand new Gates belt and three bolts are also provided in this kit.

An illustrated install guide is included with each kit.

I thought the turbo was exhaust driven?

A pet peeve Jay. Not against Madness but the ad copy generated by MPx that you quote. They can't underdrive something 20% and claim it doesn't affect the a/c. I wish they would change their wording to more accurately describe the after affects of pulley installs.

I've used underdrive pulleys for years on six or seven different vehicles. They ALL affect the a/c to some degree. You'll notice it in climates like south Florida if you drive with your a/c on most of the time. In Vermont during November, not at all. That's my point. The degree to which you'll notice it depends on the individual and their use of the air conditioning but it's nonsensical to claim something is affected 20% without having an affect. MPx, noting the accessories post pulley install, writes "they still function normally." Well yes, if they're implying that when you hit the switch, the a/c turns on. Notice they don't claim "they still function as efficiently." If your car weighed 20% less, you'd notice. If you lost 20% of your horsepower, you'd notice. If your lights were 20% less powerful, you'd notice. If you got 20% less MPG, you'd notice.

Pulleys when done right make horsepower and the MPx unit IS done right but to get the same level of a/c efficiency as pre-install, you'll need to either run your a/c longer or at a higher speed. If that is of little to no consequence to an owner, than the pulley is a great way to make a few extra ponies but it most certainly doesn't come without some kind of compromise. Once again, the product itself is great. I just wanted to add something to those unfamiliar with pulleys who might live in areas where the heat outside can really tax an a/c unit and that's with OEM pulleys.

Seafarer...why don't you send and email to Cory at MPx and ask him if he would mind testing the pulley set-up to show the difference. MPx is in Texas, from my understanding it gets hot there too. Perfect time with summer upon us.

Thank you for the feedback.

Our goal is to install this kit on our ABARTH and then provide personal feedback. Once we do if we find it any different then what the manufacturer claims we will certainly revise it. It gets pretty hot in So Cal as well and I love to use my AC in the ABARTH, so I will certainly know if there is a noticeable difference.

We are in Houston and have this installed on our Abarth. Houston is probably one of the best places to truly test if this affects your AC (HOT AND HUMID). As of this time, we have not noticed any change with the ac in regards to cooling. Definitely a great upgrade and easy to install.

I'm thinking the only way to accurately test the pulley's affect on the a/c in a real world scenario would be to detail the length of time it takes, pre-install, to bring the interior temp down to a specified point in degrees from a base temp and then repeat the procedure post pulley install with conditions duplicated. Hell, it might only be two minutes...which would explain why some "feel" no change.

My observation comes from two angles. Personal experience with pulleys and the declaration that something can be underdriven 20% with no change. It's obviously being affected...by 20%. If MPx's ad copy was "despite being underdriven 20%, we found the a/c unit still functioning efficiently enough to cool the interior when needed" I'd say that would more accurately describe the product than to declare there is no change in a/c performance whatsoever.

I realize for many, if not most, folks, it's splitting hairs but when something is under driven, there is going to be some affect on the accessories being underdriven. Perhaps owners won't feel it or if so, will compensate by simply dialing the blower to setting four instead of three. Problem solved.

It's not as if the change can't be dealt with but yeah, there will be some change for sure. In 30 years of modding cars, I've never purchased an underdrive pulley that had zero affect on the a/c. Then again, I can tell when my home a/c thermostat has been adjusted one degree off baseline. I'm not kidding. :p Anyways, nothing I've said should cause any hesitation for a potential buyer of the product. It definitely will free up some ponies.

My two issues are
A. There is no way it doesn't adversely affect the ac's performance.
B. someone correct me if im wrong, but the ac clutch disengages at wot. So how did they test this on a dyno, by feathering the throttle?

I'm still waiting for an answer, the title says "pulley kit for your turbo" but I am under the impression it is exhaust driven.

They meant for your Fiat 500 model with a turbo e.g. 500T or Abarth.
This is the accessory pulley/belt that drives the AC compressor and Alternator.

For the Turbo model FIATs

Thanks for your responses on "turbo" I was sidetracked when it read "for your turbo" Probably would be a bit more accurate if it was written "for your FIAT w/turbo". <meaning Abarth and 500T.>

Again, thanks!
