clarification from someone who has some knowledge to know (don't know the rest of you)Dont Blink wrote:i think what AEM is saying is that the crankshaft pulleys(like unorthadox) cause the harmonic vibrations which put a ton of stress on the oil pump(i seen 3 shatter that ran unorthadox pulleys). AEM sales pulley's for the power steering and altenator rather than the crank pulley. they are lighter,so really they dont "add" power but since its easier for the motor to move you could actually see some power from it(maybe 1-2 since the pulley's your replaceing arent that heavy), or you could just remove the power steering and actually make more power than the pully's would give you.
those crank pulleys are a shit load lighter than the factory one...i know that...
i have never ONCE seen someone submit actual proof that a non stock crank pulley caused engine failure on a honda. honda motors are internally balanced, however engine harmonics does come into play at high RPM. i have seen people constantly blame the "new crank pulley" they installed in relation to their engine failure, but the prior condition of the motor is never given, not only that but a teardown of the motor and inspection of the main bearings is NEVER done (From what i have seen) thus just leading to more of the myth that the crank pullies cause problems. i for one do not believe that they do, until i see someone with an ocilliscope testing pullies, running pullies on motors, disassembling and inspecting motors that claim that the pulley caused the problem, i will continue believing this fact
