Why should I upgrade from a stock harmonic balancer?
Why should I upgrade from a stock harmonic balancer? Hey guys. Tried finding this answer but haven't found much about it. Anyways, money is a little tight right now (have $1500 and $1400 of that is saved for trans rebuild + clutch). My setup eventually will be a 347 + turbo, m6, DD, 550rwhp or so. Keeping A/C, no "sound system" or crazy electronics. So is the only reason of getting an aftermarket U/D system (such as Powerbond) to grind out 1 or 2 more HP (if that), and a smoother running engine?? Convince me why I should take a $100 out of my trans rebuild & clutch for a U/D system. The motor is currently out of the vehicle so it would be an easier job to change now, but I can always do this 10,000 miles later when I have the money.
you will prob see slightly more than 1-2hp. now its not 20 but every little bit may help. i have a powerbond and feel it was worth it. the install is easy motor in or out. if you want to sqeek every bit of power out of your ride i say it would help.

You would do better whacking off to a picture of a naked fat guy. At least then the waste of time for a dissapointing result wouldn't cost you any money. Underdrive pulleys only have one legitimate reason to exist. This reason is to keep from overspinning accessories on a highly modded motor that spins to WAY more than stock rpm. If you aren't spinning high enough to explode your alternator, I wouldn't bother swapping pullleys.

I didn't have to magically conjure this. An underdrive pulley nets a very small HP or ET gain due to less rotating mass. It does so at the expense of driving the alternator and power steering pump slower(and water pump--oops). That smaller mass also does a poorer job of dampening crank harmonics. In the meantime, it drives all of the accessories slower.
