The side effects of underdrive pulley kits?

[Ian.G]

Hi folks,

I am maybe going to order some new inner tierod ends for my hachi very soon as one of them has some play in it. I may end up ordering some of the ueo-style 'branded' ones so It may pay to get a few more bits at the same time.

One of the other things I am interested in is a lightweight underdrive pulley kit as I am hoping to get my engine overhauled soon and makes sense to do at this point. Maybe like these



I know they are often lighter and lead to less mass the the engine to drive - but I also believe they can alter the gearing of some of the ancillaries on the engine - in these cases maybe the alternator and water pump.

Does anyone have any experiences of running these on a 4AGE?
