Indeed that sucks balls :wacko:

How did that happen Robbie?

Did it occur at high revs or just normal driving?

I think that further investigation why it flew went off is warranted before you go ahead and acquire another harmonic balancer.

Ross Tuffbond balancers (metal jacket types) are renowned for spitting belts.

Also, there plenty of members that run standard / OEM harmonic balancer Robbie and don't throw any belts - food for thought.

Yes, but a standard balancer isn't going to provide the same harmonic damping protection to the engine as a metal jacket, especially at higher horsepower levels that what the original damper was designed for.

I think you'd be surprised actually at how good the OEM balancers are. They're not much good when they're 20 years old but a new one is still a very good bit of gear.

Good point - but ignoring the belt issue, are they AS good at harmonic dampening as the Metal Jacket?

If the Metal Jacket is even slightly better then is it not a worthwhile precaution, especially on an all out build?

Again, assuming that the belt issue was not a factor.

I agree, however Robbie's car is not a drag machine and I don't think a harmonic balancer is entirely mandatory in his situation. Just my opinion.

A better balancer should help prolong the life of the oil pump, even under normal driving conditions, so surely that's a good enough reason in itself to use the best balancer you can get?

There is also another MJ revision 306202X2 which I'd say is version 2 of yours, which could save you having to go to an underdriven pulley?

Does the P/S pulley look different on this one compared to yours? Could be a better option than an ugly extra pulley?

Actually my p/s pulley is already under driven. I do have a spare one of the above so I will check for any differences.

Yeh that extra tensioner set up looks like dogs balls! Thanks again for the input mate, appreciate it.

I threw a few gates belts with my metal jacket on my 26/30 between 5/6000rpm with 330rwhp went to Bosch belt and haven't had any more issues

Interesting. Thanks

Yeh at high RPM, no less than 7,000...New belt is on and will be watched closely!

Seems to be the case Ants. Will be working with 'the rock' (mechanic) and no doubt we will have it sorted soon ;)

There is a thread in the forced induction section, enough examples in the thread to warrant a change to ati or OEM

Thanks Simon, have now read through this. See what happens...as always time will tell :cheers:

So got a few more shots in on Sunday, will get the rest up over next couple of days

Have you seen this brochure?

If you could track down a real one it would be a good addition to put in the glovebox!

    • Well, the trouble with that ^^ is: The configuration shown is absolutely a 1-way, not a 1.5-way. There is no way that a 1.5-way can be said to offer LSD action only on acceleration. If Nismo cannot get that right, then it is impossible to believe their documentation. That ^ is not a 1.5 way setup. That is a 1-way.   And so now I have allowed all doubts to flourish and have gone back to look at the MotoIQ video. I originally made the mistake of believing him when he said "this is a 1.5-way" at the ~6:10 mark. Because what he did was take the gear assembly out of the 2-way opening and just rotate it one place to the left to drop it into the 1-way opening. When he dropped it in there, the cam was "backwards" compared to the correct orientation shown in all other photos of that config. The flat shold have been facing the 1° ramp side of the opening, not the 55° ramp side. And I thought, "gee that's cute", but I was concerned at the time, when he put the other ring back on, that the gap between the rings looked like it was wider then in the 2-way config. And then I said a lot of things in my long post on Tuesday that could only make sense if the guy from MotoIQ was correct about what he'd done. BUT... I have now done my homework. I grabbed a frame of the video with the 2-way config, and then grabbed another with the "1.5-way" config, snipped out the cam and opening of that frame and just pasted it direct on top of the 2-way config. I scaled it so that the triangular opening was almost exactly the same height in both. AND.... the gap between the plates is wider with the cam installed in the triangualr opening backwards. That is.... it cannot go together that way. There would be massive force on the plates all the time, if you could even reassemble it.  So, My statement on the matter? The Nismo diff is actually only a 2-way and 1-way. There is no 1.5-way option in it, regardless of what they say. Here's a photo of a real 1.5-way ramp opening from Cusco (along with the 1 way option). And the full set of 1 through 2 way options from their racing diff, which is not same-same as what we'd typically be using, but...the cams work the same. A little blurry, but it comes from this Cusco doc, which is quite helpful. AND.... Cusco do in fact do what I suggested would be sensible, which is to have rings that do 1 and 1.5, and 1.5 and 2. Separately.  
    • Welcome Adam. Car looks great!
    • "With a 1.5-WAY, the LSD is effective only during acceleration."
    • Well it wasn't as easy as I thought.... and it also wasn't in my original manual which I did end up finding. They discuss the process in the Nismo catalogue though and it requires slight machining. Page 145.  NISMO PARTS CATALOGUE 2020
    • I'm an idiot, my intercooler is rated for 1000hp. I had clicked on the wrong product. Knowing the delta P would be nice, but I'm doubtful I'll do it. Now as for an EMAP, that would be great and I'll get around to it eventually but from my findings in my last post, I'm considering a turbo swap now.
