I've also heard negative stuff about the Ross which is a shame being an Aussie part. They do seem very concious of fixing the previous issues though.

A big reason a lot of crank snouts get rooted is balancer bolt tightness. They need to be stupid tight (400ish Nm of torque), waaaaaaay tighter than a rattle gun will go. It must be done by locking the flywheel and an extended breaker bar.

You may have to conclude that people around here have stopped buying them and that you may have to be the one to find out if the problems have been fixed!

So you have experience with it, or you're just talking up all the shit people gave you for free?

No, I'm talking out my arse. Clearly. That's what I do. I make point of posting stuff like this for laughs.

You tool.

You sound like a big internet tough guy.

Call me skeptical but talking up these balancers while advertising in your build thread that your car (that doesn't yet run) was on the Ross Performance stand at WTAC makes me think you're full of shit.

Not the only car I've ever built. Not the only car I've been involved with use these parts. But what do I know. The quickest R32 GT-R on the planet uses one. But what the f*ck do RIPS know. Maatouk Racing VL runs one. But what the f*ck do they know? Quickest WRX in the world uses one. But what the f*ck do TRP know?

You think you know a thing, but then you realise you don't. No internet tough guy or bias required.

My Ross damper was purchased in the pre Omega technical days. We recently pulled the engine to fit a bigger sump and open up some clearances only to find the balancer has chewed up the nose of the crank. Car has only done two dyno sessions and one light shakedown. Bearings looked good fortunately but we have some work to do to clean up the front of the crank.

The guys at Omega have the balancer for inspection at the moment. Have to say so far they've taken it seriously and aren't doing any of the finger pointing you normally expect in this sort of situation. Sounds like there have been a number of significant design improvements since Omega took over as well.

Whether I'm game to put it back onto the engine will depend on what happens next.

An update on this one. The guys at Omega have been very proactive and despite not finding anything out of the ordinary with the old damper have sent me a current version replacement. All going well the engine builder will have it back together soon so I can give it a run.

It's a nice bit of gear.

I've just ordered a new Ross balancer (the basic metal jacket one) for my 300kw RB26 @ 110,000kms stock 8400rpm redline, doing it as a bit of preventative maintenance together with engine/trans mounts.

Speaking to them, since they were bought out by omega 2013-14, there were several design changes to alleviate the tendancy of the old ones to spit power steering belts, as well as repeatability for more consistent manufacturing batches.  They have since introduced their own in-house CNC machining.  Their balances are also serviceable for around $300 (replacement of the rubber cartridge).

My tuner also mentioned he prefers the placement of the crank trigger (potential future upgrade together with ECU) on the Ross.

I know alot of people has since moved on with ATI, they mentioned around 50% of their sales are overseas with NZ being a big customer base for them, interested if anyone can add any insider knowledge here regarding these?

I know of one guy that had a Ross dampner on his 30, which failed.. not sure exactly what, but IIRC the snout broke. I've also heard of others too locally. Since then, they moved to ATI, and haven't had such issues. Not saying that the ross dampner is to blame, as it could also be other issues, as the RB30 crank is prone to breaking if unprepped, or being nasty with the clutch.

Yeah interesting, hopefully all the new gear (balancer and engine/trans mounts) doesn't wake up the nissan and cause and unwarranted reaction.  The idea was to try and keep the bottom end happy for as long as possible.

Reading the ATI thread, they have also had a number of reported issues of belts been spat.

Alot of workshops are using ATI ie. Dahtone, Powertune and PMC, but to my knowledge, CRD and my tuner (MRC - they've used both without issues) use the Ross units.

Yep Con at CRD told me to get a Ross balancer since I was changing to a trigger kit, so full trigger kit with 12 tooth balancer was obtained. CRD did my Nitto 2.8 short motor. Haven't leaned on it yet so let's see how it goes.

Before that I also was running the old Ross tuffbond balancer from new in 2011 and never had a problem with that either, no belts thrown. Before that I did destroy a factory balancer which cracked my crank in 4 places. Maybe people have been using 33/34 ones on 32s or visa versa regarding the belt issue as offset is different.

The issue of belts being thrown out is most likely going to be the power steering bracket/assembly out of line, esp when going 26/30. I'm in the process of getting this done, and I was advised of this potential issue when i bought my ATI dampner. This isn't an issue with the ATI, but moreso with the brackets etc. I've seen power steering belt(or maybe the AC belt) thrown out on a dyno during an initial run in.

From reading other's experiences, i think both ATI and Ross units have been the culprit of throwing belts.  Where i have read more regarding the Ross is like the above case where there has been some evident damage to the nose of the crank.  Not sure if that is something that still exists with the long-nose crank RB26s, hoping it has been resolved with the newer units.

    • Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.
    • No those pads are DBA too  but they have colors too. I look at the and imo the green "street" are the best.
    • I’m not sure what happened I told them about sonic tunes free OTS tune and the next the I know .. I was booted..   To funny 
    • Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).
    • I'm not going to recommend an EBC pad. I don't like them. Just about anything else would suit me better. I've been using Intima pads for a while now.
