OMGGTR Posted June 21, 2011 Share Posted June 21, 2011 Straight up... 350-400 kw at the wheels how much power can the standard hamonic handle.. before i gota buy one... cheers Link to comment https://www.sau.com.au/forums/topic/368511-rb26-harmonic-balancer/ Share on other sites More sharing options...
Beer Baron Posted June 21, 2011 Share Posted June 21, 2011 it's not really a straight answer. but my advise is start looking for an ATI balancer if you want 400kw and want to use it hard on the track. if you are 100% street car with 400kw it's not suffering the same kind of RPM, power and acceleration as a track car would be with the same power. in a 400kw GTR you'd be lucky to be using much more than 200kw at 6,000rpm on most days on the roads with the odd squirt to 8,000rpm. not like on track where you are driving with the throttle buried for 50% or more of a lap. if you only want 400kw and it's a street car perhaps consider an N1 balancer as a budget option? they are a bit of an improvement over standard and not too expensive (less than $500) vs $1000 for an ATI.

SimonR32 Posted June 21, 2011 Share Posted June 21, 2011 They can handle massive power, I've seem one easily go over 650rwkw BUT If you had the cash (and if you don't start saving) I would be going straight for a ATI one and having it balanced with your bottom end...

Beer Baron Posted June 22, 2011 Share Posted June 22, 2011 yeah, forget the N1 balancer then. for $500AU + post buy the ATI one from the states. Link to comment https://www.sau.com.au/forums/topic/368511-rb26-harmonic-balancer/#findComment-5877627 Share on other sites More sharing options...
r33_racer Posted June 22, 2011 Share Posted June 22, 2011 You dont balance the ATI units. They are zero balanced from factory. I believe the Ross units are the same. The Ross damper would be good enough for that power level. Probably much the same price too.

sucram Posted June 23, 2011 Share Posted June 23, 2011 ^ You dont balance harmonic balancers, or duel mass flywheels with crankshafts Link to comment https://www.sau.com.au/forums/topic/368511-rb26-harmonic-balancer/#findComment-5879317 Share on other sites More sharing options...
Beer Baron Posted June 23, 2011 Share Posted June 23, 2011 yeah absolutely. they are neutral balance so you most definitely don't want to mess with it. they are also a harmonic dampener which is slightly different to a regular balancer (which can just be solid metal and should be dynamically and statically balanced with the whole rotating assembly). when using a neutral balance harmonic dampener like that you just need to balance all the other components to be neutral as well. it also dampens harmonics which is it's real purpose (ie not a balancer, but a dampener).

Tangles Posted June 23, 2011 Share Posted June 23, 2011 Ross Tuffbond balancers can be bought for $480 from RAWS Brokerage, they also sell Ross Metaljacket for #$640 - http://rawbrokerage.com/Ross-Tuffbond-Nexus-Harmonic-Balancer-RB26-R33-306103.htm ATI balancers used to be around $600 for the 600HP version, havent seen a current price on these of late though. FYI Ive got the ATI '600 hp' version on my built Rb26.

Exactly! They dampen harmonic vibrations. Only an externally balanced engine has offset weights on it inorder to help balance the rotating assembly, referred to as a harmonic balancer it dampens and balances. That usually is only common in old school v8's like the a 454. Inline 6's like our RB's they only dampen, since our engines are internally balanced. So really its only a harmonic dampener.
