but then again if you are using it on a well put together modified engine, I would not expect any noticeable decrease in operating life from one. Honda makes a ctr pulley that does not have a harmonic balancer in it for their race engines, which people run on daily driven cars for years with no problems. Is it technically worse for the engine? Yes, but not measurably imo; I wouldnt plan on getting 250k out of a built engine, if getting those kind of miles out of a engine were a priority, I wouldnt run an un-damped pulley. At least for Honda engines- I’m sure there are engines out there which rely more on the harmonic balancer than others, and on these it would probably be a more noticeable detriment to the motors life.
