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!

    • Bummer...yeah i "need" something to "ease" up the work and for my driving it would be enough.    Iam counting the tune "without" turbo. I do not mean "cheap" like something from Temu around 200 USD, "Cheap" is something around 1000 USD? 
    • Starter motors used to use the weight of metal (magnets) to provide torque. Now they use (more) current instead. This. It's completely normal.
    • So thing that had me stumped, but I think is OK....is that when it was up in the air, in neutral I had it running to bleed to coolant while I put the wheels back on. I noticed the rears were turning (slowly) which I'd never seen before 20250928_163512.mp4     Because there had been an issue with clutch slip due to pedal adjustment on the dyno, I assumed there was still and issue so spent some quality time upside down under the dash adjusting the pedal....but no matter what I did the wheels still turned in neutral. Even disconnected the master cylinder to pedal rod and same. In despair, I even removed the clutch slave so there was no chance of any preload causing it.....still happened. So either: 1. Something is not right in the bellhousing, or 2. Its a thing sometimes with cold, thick gearbox oil Internet says it might be 2, I hope so!
    • OK, few more things sorted and it is ready for a shakedown on 10-Oct, with one weird thing. Changed the run in oil and filter for the good stuff. 8l came out, about 8.5 went in with filter so that looks all good. Changed the starter (again), this time for a brand new one, works good. Interesting that the Taaaarks one is shorter than factory but spins harder, I guess electronics have moved on a little in the last 30 years. Will be nice to have a bit of extra space under there. Put the timing cover back on, and noted where the cam gears were set as a record.  Will need to double check the timing but it is pretty close. Also put the coil pack cover and intake snorkel back on. Exhaust Inlet Changed the water out for coolant, bled up nicely. Removed the rear brake pads (well worn factory sumitomo ones!), gave the hardware a good clean and reassembled. I've put bendix XP on the back again because the price is excellent at $150 a set and they worked well on the V37. Front pads have plenty so no issue there
