guys,
i had a lil chat with a mech, and i got some contradicting information. Well, its regarding the usage of aluminum crankpulley.
It seems, its more suitable on a short distance testing only(drag or traffic light to traffic light) and on hill climbing, it will suffer. Plus on a long term, the other parts of the engine might KO, such as alternator,power steering pump or even the compressor. The reason he said for that is because, the cycle count is different with the usage of the aluminum crankpulley. He also agreed that it does give a lighter response but not for long aswell.
but most of the aluminum crankpulley users here are happy with the usage right? no complains??
