Good notes Adam!

Definitely one of the biggest themes of the day was how the driveline is designed with shock absorbing capability, and changing this with stiffer components can lead to damage if the whole system isn't appropriately matched.

Yeah i reckon its something like this below - area under the curve is the same, but peak load/force is much lower with a soft (sprung) clutch. Engineering 101.

Cheers guys for another great tech arvo.

Thanks to Award, Terry and Trish :)

Learnt some new things and got in some laughs as well.

Thanks Adam for the notes as well!
Will be looking forward to the next one :)

Was a damn shame I missed this, with both sleeping in and my calendar reminder not set properly I got the reminder 10 min's before the event :(

"Solid mounting of diff cradles also increases rigidity in a way that's detrimental (for the gearbox? or drive train more generally?), so make especially sure you use a sprung center clutch if you have a solidly mounted diff cradle."

This is good to know as I've just fitted a diff craddle and will be putting in the g'box brace in soon too, guess with the brass button clutch this is going to destroy my gearbox prematurely. :) JOY hahaa

oh, and lol.. not sure how many people found out in the day, but it turns out Terry and Trish live 2 doors down from me. It didn't click until we went outside for the ridiculously big spread they put on and i saw their car.

all in all, i think i learnt more from this tech session than any of the others.... thanks to all involved in organizing and putting the day on.

shift sedately and you will be fine, so no time attack shifts for you just yet!

I'm sure you'll find it's not so much how you shift the box as it is how you reengage the clutch that destroys boxes, this will apply to both going up AND down gears, should be done just like a motorbike, find friction point then release clutch not find floor then release clutch

The other bit I got out of the day (more informative than anything) is that the only major difference between the series 3 BCNR33 boxes and other 32/33 boxes is that the syncros are "pad-type" rather than held in by circlips and also have a stronger (bigger) 5th gear synchro making them the design of choice if you have the option.

He also recommended that cleaning the gearbox can be done by running ATF in it for a while. Could be useful for those wanting to move away from smurfsblood which is nearly impossible to remove.

It was also interesting that Terry mentioned there is not a major difference in the various LSDs out there however for big power/time attack cars he did seem to recommend the Cusco up front. Seems he can also modify the standard ones making it potentially a cheaper option.

brass button clutch what friction point ?? HAHA

Yeah i think we was saying that like gearboxes, which are pretty much all the same in how they work, the factory, Nismo, Cusco etc LSDs are also pretty much the same. He can setup the rear to be tighter, however, since the after market ones are larger/beefier they will last longer.

I destroyed 5 brass buttons in 2 years due to the torque and everyone of them had a friction point

The distance between off and on was very very small though

no worries I have no torque HAHA

    • It's actually really good advice. And I do try to do it. I actually have 2x 3KG dumbbells that sit right beside where I sit. And I look at them a lot. Use them a little. But I'm trying to do more with it. At the moment I'm going through a heap of weight loss too which will help. I cracked into the 85kg mark this week. My weight used to have me sit consistently between 93 to 95KG! That definitely doesn't help. I've also got POTS, which flared up after I got slapped with COVID a few weeks back, and POTS really smashes fatigue and stuff into you, and has a thing even called "excercise fatigue". Basically even the minorest "excercise" (walking from the garage to the house) causes fatigue! And one of the treatments (Other than a med I'm on) is also... Excercise... Ha ha ha So it's why I'm trying to play the game of "might as well" and trying to push through things. For ADHD specifically, the general recommendation is "excercise". When you dig deep into it though, while any excercise is good, the best type is "explosive" excercise. So training for a sport like squash, tennis, even soccer. Things where you need to get the whole body able to "explode" into a different direction change. They've found with explosive sports, (I can't think of the proper term they have for it) that it actually makes the brain grow and become bigger in specific areas. The areas where ADHD causes those parts of the brain to be smaller than normal! But definitely, trying to push myself, and break those bounds mate, and get healthier!
    • Be more active mate.. , not taking the piss ❤️, your long term health will love you for it I would think something like a kettle bell or 2 laying around in areas you go past during the day would be awesome for ADHD.... "Oh look, a kettlebell", and exercise helps your brain health as well My mates son was a bit of a problem child, diagnosed wirh ADHD, and some other things that had his brain occasionally doing loops, until we got him into a training program, the difference after he started training was amazing, he had more focus, and his fitness levels exploded, it is like he is a totally different kid to be around Brain chemistry something something Stay fit stay strong mate
    • I had never actually looked into it, but aren't onboard compressors a thing in trucks?
    • Read the ECU for fault codes or have someone else do it. A faulty coolant temperature sender is usually listed in ECUs. If the sensor itself is not busted it can also be a bad ground connection. Or in a really unlucky case, damaged wiring.
    • Can't be a Futjitsubo as those are made with a flex piece and Reimax is smaller in pipe diameter. If anything it is closest to a Mines pipe, but evidently it is not an actual Mines pipe.   Classic word humor
