Comments: By far the easiest and most useful upgrade you could make to your 1.4L Dart. Immediate, noticeable difference, like changing from hiking boots to running shoes. |

Comments: I would say this is a must upgrade for your 50, abarth. The installation is very easy and the gain is immediate on all rpm range. Just a note on the information provided for the installation on printed paper: in order to release tension from the tensioner you need to push/pull your wrench counterclockwise and NOT clockwise. Other then that I'd say 5 on manufacturing quality! Good job mpx team and thanks for this wonderful product for my 500 abarth. My drive is even funnier now! |

Comments: The install was very easy. The Renegade just requires the wheel well liner to be moved aside and it gives perfect access to the pulley. The test drive showed the engine felt much more responsive. I don't think I notice the extra power, but I sure notice how the rpms spool up faster. It's like taking iout turbo lag. I really like it with the Tune and clutch delay valve removal. |

Comments: Disclaimer: not a daily driver. I have done about a dozen modifications to my Abarth, all engine performance focused. From adding pedal controllers, oversized intake kits, ECM piggybacks, ported throttle body, BOV, waste gates, etc. they all did things. For a long time my absolute favorite was a pedal controller. Most bang for the buck. Didn't add HP, but the drivesbility was immediately improved. I recommend it as the first mod to every owner.I know that undersized pullies work, because science says so. On a whim I ordered the ported throttle body and lightweight pulley kit and WOW what a difference. The engine snaps up so much faster. Shifting is smoother. So much fun to drive after this addition. Add the short shifter I have and the Abarth is an absolute dream to drive. I would highly recommend this kit to anyone wanting to free up HP to use putting power to the ground. After about 300 miles I have not noticed any negative effects using the AC, in fact the car runs better now when using AC due to less drag, and my battery should have been replaced 2 years ago yet it has not suffered any charging issues. |

Comments: I have never done a review but I thought this deserved one. The install was not quite as easy or as quick for me as others have said and I have plenty of experience working on vehicles. But the upside is it truly makes a difference, I have added a air intake and piggy back and I can feel what the lighter pulley does, it lets the car rev up quicker and that makes me smile. |

| Must do mod |
| Posted By: Paul Ligtenberg |
| Location: Davis, CA United States |

Comments: If you are serious about improving the performance of your Abarth, this is a must. Much better throttle response and noticeable hp gains. Our cars have sensitive ECUs, so take the time to get the pulley wheel centered and torqued down properly, or you can get a CEL temporarily, until you do. Great low cost mod! |

Comments: Hi everyone, I want to let you guys know that I'm very happy with my investment into this kit. On my jeep renegade at 4000 rpm the mottor wasn't pulling anymore and after this kit now the engine is pulling up to 5000 rpm or at least that's how it feels |
