How much power can the standard Harmonic Balancer handle?

If I am not outputting more than 600HP @ the engine...

Do I have to put in a Ross Racing / Metal Jacket Harmonic Balancer?

Thanks in advance! :yes:

Edited by V36

I suppose it does.....the more power the engine makes the faster the revs rise when accelerating, and so hence the larger the inertial acceleration forces and loads on the front pulley when it is spinning itself and the accessories up.

If that matters, that is.

Ross Racing / Metal Jacket Harmonic Balancer?

You should do some google on what I just quoted and add in the word failure

A brand new OEM balancer everyday for a mild build.

Got a bran new Genuine balancer here. Mine was starting to crack and with the amount of cash i have throwen at the engine it was a no brainer, plus working at Nissan and getting cost price was even better!!!

    • yeah I've never understood that either.... And to answer an earlier question, I write the date on open bottles and throw them if more than 12 months old (which they almost always are, because I don't need to bleed them unless I'm changing lines/calipers etc in between)
    • Nah, the one that hit the boot was a big steel locker, around 6 foot height, 4 foot wide and 2 foot deep, empty it weighs about 15kg and had about that amount of stuff in it The photo didn't give a good representation of the actual damage, the large ding on the passenger side was about a inch deep, the one on the driver was about 1/2 inch deep, right on the curve, where the inner boot frame doesn't let you get behind it with a dolly Basically the same issue with getting behind the damage on the centre of the boot We could have filled it all with bog, but my OCD would be triggered every time I looked at it, knowing what hides beneath  As for the locker, I did get the shits with it and put it in the scap metal bin, but, I pulled it out and it is now sitting in the garage at home full of car servicing stuff, cleaning gear and random tools, it's going to pay for it's indiscretions
    • Whilst I typically don't cheap out on things, if I can save some money, like $1000, on a clean straight panel, that gives me $1000 to spend on other stuff, basically free money really 🤔 🤣
    • Is the toolbox that damaged the boot seal the same item that fell on the car during the storm a while back?
    • Who are you to deny yourself? I’ve said this many times to myself and apart from getting what I really want, I go quiet for a while whilst working out what I just did to my savings and how will I afford what it cost, then, next payday…
