885, UDP Cause Crankwalk? Posted by alexries, Apr-19-01 06:40 PM Hey I called my local performance shop to ask them if they can order me up an AFX UDP and the guy to me that they don't sell or install them because they "drastically" increase the likelyhood of crankwalk. Is this true? I haven't heard anyone on this board complain about that, and I don't think that we'd all be doing/wanting UDP's if it did, right? | |

886, RE: UDP Cause Crankwalk? Posted by eclipsekaiser, Apr-19-01 07:35 PM I say to call back that shop and tell them they are full of $hit. | |

887, RE: UDP Cause Crankwalk? Posted by phrenzy, Apr-19-01 10:10 PM AHHHHHHHH!!! Do not use that word here...we are here to avoid that word. I've never heard of such a thing. Might they be confusing you with a 4G6 person? | |

888, RE: UDP Cause Crankwalk? Posted by klipzracer, Apr-19-01 11:27 PM hmmm...i'm not exactly a 420A engine guru but maybe we should be open minded about this. could this be possible??? stan??? skrilla???? anybody??? or maybe he was a dumbfuck and was thinking all eclipses sported the 4g63. | |

889, RE: UDP Cause Crankwalk? Posted by MWC, Apr-20-01 12:48 AM NO not possible. | |

890, RE: UDP Cause Crankwalk? Posted by Michael_97RS, Apr-20-01 01:25 AM Ahhh another machanic who thinks we have a harmonic balancer. To what MWC said Ditto. The problem was with the bearings and crank on the 2G64. And since we don't share those parts we're okay. It's an isolated problem I don't know that the term crankwalk existed before the 2G GS-T/GS-X motor came out, I'd never heard the term prior to that. Bearing failure and crankwalk are two different things. Don't worry about the UDP you'll be fine I love mine and there are plenty of people here who have been running them for a while with no sign of problems. And just an FYI a heavy duty clutch (ATC 2600 is infamous) will induce crankwalk faster than a UDP on the Turbo cars. | |

891, RE: UDP Cause Crankwalk? Posted by klipzracer, Apr-20-01 02:30 AM aaaaaaaaaaaaaaaaah.......i feel much better, now. | |

892, RE: UDP Cause Crankwalk? Posted by Michael_97RS, Apr-20-01 05:30 AM Glad we could put your mind at ease klipzracer. | |

893, RE: UDP Cause Crankwalk? Posted by guest, Apr-20-01 07:15 AM I was just thinking about how valuable this board is to us. People on here know more than most machanics about our cars and the 420a and as far as turboing our cars foget about it. This is the best place for information. I dont know what I would do with out this board. And as far as the crankwalk thing......That guy must have been smoking crack!!!! | |

894, RE: UDP Cause Crankwalk? Posted by alexries, Apr-20-01 07:25 AM The guy I talked to did mention something about a "harmonic balancer" but he didn't know if our 420a had one or not. I didn't know what the F he was talking about so I went with it. | |

895, RE: UDP Cause Crankwalk? Posted by mike95rs, Apr-20-01 08:35 AM the upd "could" cause your main bearings to wear out a little prematurly. The reason the stock one is so heavy is because it has a damper in it that takes stress off the crank, but even with out the damper it doesn't have that much stress. If your really woried about it AEM has upd's that go on the altenator and psp instead of the crank, but there alot more expensive, I think around $500. I would go with the afx. | |

896, RE: UDP Cause Crankwalk? Posted by Michael_97RS, Apr-20-01 09:05 AM I have to disagree a little. The reason the stock unitl so heavy is that it's much cheaper to make one out of cast iron than it is out of aluminum. Which is where the weight is. all the damper is is a rubber ring to cut some of the vibration down because there is such weight in the pulley. Yeah you may get a little more vibration on the crank. But you also are putting less stress on the crank and bearing due to the smaller weigh being turned. I have one and the car runs smoother since the install. | |

897, I agree... Posted by Skrilla, Apr-20-01 01:55 PM With AFX installed I feel our engine will last longer from less stress. The perfect example is Len. He has been running his car pressurized for years now with one and even makes 400% over stock HP AND uses the AFX UDP. I'm convinced The AFX would do everything to help our engines as opposed to hurt. | |

898, RE: I agree... Posted by RSin oRACLe, Apr-20-01 02:10 PM the systems that the udp run are not essential .. they are basically accesories .. so with that in mind spending less power on them will with out a doubt cause less stress to the engine ... unless of course your foot is trapped in the throttle body ..lol | |

900, I'll second that Posted by VX100, Apr-21-01 06:35 AM Same here, after the AFX UDP install my car ran smoother. Also, now I don't have to choose between acceleration and A/C, I can have both :) and I can drive around in 5th gear at 1500 rpms without the car lugging; before I wouldn't have gone below 2K rpms in 3rd-5th before the pulley. I can't imagine not having it on now. | |
