turbor850 Posted July 25, 2004 Report Share Posted July 25, 2004 you have to create a "jig" in order to balance a 5 cylinder motor Link to comment Share on other sites More sharing options...

Guest DougK Posted July 26, 2004 Report Share Posted July 26, 2004 you have to create a "jig" in order to balance a 5 cylinder motor←"jig" meaning something you can't build in your garage with bamboo, duct tape and JB weld. You just balance everything to the same weight (or darn close) individually and balance the crank like any other motor. Link to comment Share on other sites More sharing options...
blown_volvo850r Posted July 26, 2004 Report Share Posted July 26, 2004 Yeah 5-cylinders are extremely hard to balance and get the secondary harmonic distortion tolerable. Did Porsche originally design the 5-cylinder? That's what someone told me...~Lee Link to comment Share on other sites More sharing options...
BlackT5 Posted July 26, 2004 Report Share Posted July 26, 2004 I was told that the 5 cyls actually balance out better than the 4 or 6s. My car is so incredibly smooth with the new motor, it's often hard to tell the car is actually running :pizza: Link to comment Share on other sites More sharing options...

I can barely tell my engine is running when in park. Don't know what they did, but it worked. Link to comment Share on other sites More sharing options...
