Well - don't get me wrong. I am very very happy to be told its nothing to do with it and find another reason for it.

As I said above, Ross is a good bloke to deal with, its good to buy Aussie, RIPS uses them too - and I still do have mine - so I am all for it NOT being anything to do with the balancer.

But when Piggaz started throwing belts and so did I, especially when I wasn't before hand - it raised alarm bells. Now ABR33.

So I felt it was worth mentioning - just in case. Lets hope we can find the real reason though.

Yea for sure mate,defintaly worth the mention, and i can imagine its rather annoying that the blet keeps getting thrown. Hopefully you can sort the problem soon and report back with exactly why its happening (ross balancer or not)

How much power are you making by the way?

in the mean time you should get one of those idlers for the belt, not too expensive i imagine and fairly easy to fit.

about ur timing belt slipping... that is very strange

Someone else on another forum having the same problem, only he worked out how to fix it... power steering pulley was on the piss! Worth checking. http://www.gtr.co.uk/forum/241625-pas-belts-flying-o

mmm.. glad he fixed it. but in my case I am 110% sure this was not the issue. Went to great lengths to ensure it was perfectly lined up and straight. Even bought a laser alignment tool just to be

But can anyone explain why i was doing flat out runs down an airstrip for 30 mins, and drifting around each turning end, and after doing the same thing after doing it 20 times already it comes off? done nothing different.

One thing I can say is the belt is quite old and shitty, could it be poor strength belts allowing stretch?

Has anyone thrown a gates racing belt? seem to be tougher..

yeah got the idler kit Joey - it did help - how could it not - but we noticed the belt still tried to walk up the back of the damper. Plus I want to know why my ATI ran without an idler and never had the issue. Remember this was the ONLY change. And hence why I was suss about it. As Ross pointed out though, RB26 Power Steering pumps often seem to be a little on the piss, hence we went to some effort to replace the bracket - face it and line it all up with a laser. Fat lot of good that did me though.. I am almost wondering if something has happened to the crank nose during changing them or something - makes no sense.

My car is only a baby in RB30 terms mate. 20psi - 350rwkw. Spins too 7200rpm - soft limiter courtesy Motec. Plus I drive like a pussy according to Gav. So I'm not bouncing off a 9krpm limiter or anything.

Frustrating doing power steering belts and then burning the crap out of yourself changing them between runs at an event. And one of them coming off decided to tear into my Spal Thermo wiring... grrrr...

What issues do people have with stock gtr ballancers that makes them change to ross?

Nissan would have spent alot of time/money designing these to work reliably on their engines, gtr stock rev limit is over 8000rpm.

Ive never had or seen a power steer belt spit off using stock ballancer.

They get worn out over time and I imagine Nissan charge a mint to buy another one.. Other wise yea they are probably the best one you can buy

Can confirm, drives like a pussy :rofl2:

Don't think its the same issue ( but I'll put it out there ), I've spat a couple of P/S belts with an ATI balancer, but only at 8500rpm and over 200kph, think there is enough flex in the clutch fan to just clip the belt..

Not the same issue as you Matt, obviously as you have electric/thermos, from memory.. but could be worth looking at for others.

This is interesting, my fan tips have tiny tiny rub marks on them. I was going well in excess of 200km/h too. Not sure if that done it though I think it came off when i was in second though...

the factory fan flexes that much....?? so your was mainly due to the RPM ?

can't be sure on either case.. there was black marks on the fan but don't know if that was the cause or the result of the belt shredding? but the fan does have quite a bit of flex ?

and both times its happened to me was at the track or an event at over 8000rpm in 4th, so 220kph+ ..?

when its not spinning, the fan tips are only about 10mm from the P/S belt.. ?? but I've only done 2 belts in about 4 years so I don't know that this is related to the Ross balancer issue ( if there is one )

Torque figures above look right but I'd have to check my book. GTR would be tighter due to the metric superfine thread it uses (18x1.5) and the fact it's an 18mm bolt instead of a 16mm bolt in the 'lesser' models.

Remember boys and girls, it's all about correct tension, not lots of tension.

That 18mm bolt is definitely doing to need that much torque to apply the correct stretch to give it the exact preload it needs to never come off.

I've seen too many come loose recently....but come to think of it....all GTRs

Answering a question above about why replace the stock balancer - It's simple. Because they are shit

When they were brand new they were awesome. 20 years later.....shit

If you could pick only 3 things to modify in the engine of a GTR to make it near bulletproof at 600-800hp it's : 1. Rod bolts 2. Billet oil pump gear 3. Good aftermarket harmonic balancer

We have proven it many many times. Although given the choice, everyone knows my decision on stock rods

So the question on everyones lips (or mine) is what exactly makes them shit?

I can understand that newer designs/materials etc could make a better one - hence why I bought an ATI in the first place, but I am interested in why you say that - how does one 'measure' how well one damper is compared to another without some pretty special equipment?

ie something in your experience must have lead you to this?

      And so, to round this out, I couldn't be happier to confirm @MBS206 has decided to buy the car. He drove down from sunny QLD with a trailer last week and it is off to its new home today. I'll let Matt confirm on next steps but I understand broadly that the plan is to leave it pretty much as is, and just get some quality wheel time with a nicely balanced car that is pretty much track ready. There are a few a jobs still to be done first but nothing too major and I think its a very smart buy Dinner last night at the Paragon with a round of VBs (mostly) for Neil

      Well, 50 pages and the end of a chapter for this car. We took it out for a shakedown at Wakie yesterday, and everything went well. There were a couple of niggles: - Oil cooler fitting leak - tightened, cleaned, stopped leaking - Radiator cap overflow fitting was leaking....Mark called it, the overflow fitting was threaded in and not tight....tightened, tested and held pressure - Small oil leak at the rear of the block, probably the turbo oil feed - too hot to get at it comfortably but probably just needs to be nipped up - leak at the driver's side rear brake line where it meets the hardline. Fitting wasn't loose, so Matt backed it off and back on, no further leaks - there's also a leak somewhere on the top of the fuel tank, maybe that cross over fuel line - that was has been left to fix when its on a hoist Otherwise than those niggles the car went great, turned great and stopped great so it was a very successful day out. I'm always really nervous when a car first hits the track after a long break, especially with a brand new engine as well but it was great. VID-20251011-WA0007.mp4  Big thanks to @The Bogan who dropped by and helped out, @MBS206 and my nephew Lachlan the apprentice.  Neil's wife Mel also surprised the hell out of all of us by dropping by; she's up in Tamworth these days but was travelling to Melbourne so had plausible deniability for turning up at the garage, it was great to see her but also obviously a bit sad all round.

      Unsolicited advice? Keep the engine as close to stock as you can. Nothing wrong with adding some boost and making a little more power, but given where you are, you really don't want to try to make it into a monster. I can't imagine the roads are up to it, and the lack of locla support when it grenades will be a ball ache. FWIW, If there is a dyno around that you can access, then brand new injectors are a good idea, which will lead you to (at least) putting a Nistune in it, which will allow you to put an R35 AFM on it, all of which will make it possible to make it much much nicer to drive and live with.
