Hi all, I have a question.

My base timing is set at 20 btdc by my tuner, and im sure it was 20 degrees before this, but I have just put on a ross balancer, and whenever i pull stuff apart I disconnect CAS so as to check everything over before re-connection and starting. Now I had a tune 1000 ish kms ago and I had Adjusted CAS previous to that to 20 degrees, he checked it and locked it into the ecu, and said it was good. However when I adjusted it, I hadnt tightened the bolts right up. 2 loose and 1 just nipped up a bit. All would be good but i may have moved it when disconnecting. So I tightened it up where it was. Check timing and its at 15 degrees, now the only variable is the balancer marks, My old one looked ok, I thought it might be rotated a little but seems fine. Now i trust the ross one is perfect.

So having retarded timing (i think) i figured no damage can happen, so i went for a drive, I only take it out every few weeks so I didnt notice any power difference. However I did a 4th gear pull right out and it had the odd cough feeling hesitation on full boost a couple of times and throughout the drive. It never has before.

So ill get to the point, is there a way to tell where it should be vs where ecu thinks it is?

Would the ross timing marks be perfect with stock balancer?

Just need some confirmation I dont want to set it at 20 and it be wrong. Im sure iv just bumped it around a tad but not sure if theres a way to make certain so I hope someone can clear this up.

Oh and I wasnt doing the 4th pull on the public road either. It was a local private air strip.

Thanks in advance

Thats what I have done, but im getting a different reading now with new balancer, im not sure if balancers are a bit different with readings or iv accidentally moved cas. Im thinking number 2

What ecu have u got! If ur base timing was 20 degrees btc then u had a tune, if u have a sftermarket ecu and the tuner has advanced the timing via the ecu to make more power then there is quite a chance that it wont be 20 degrees' all timing marks on any balancer should b as good if not better thsn standard.

Bedt bet would go to ur tuner and get a touch up tune just to b shure!

Im no expert though but thats what id do!

A tuner would rarely adjust the timing around idle unless there was a timing problem. There is no gain from advancing timing in these cells

Adjust your base timing back to 20 degrees if this was where it was set

I would go back no worries but its a 600+ km drive to do so.

If everyones confident the marks will be spot on I will just set it back to 20 degrees. Just sucks I didn't tighten it up properly!

I will contact tuner tomorrow and check but im dead sure it was 20 on balancer.

Just needed some confirmation thanks

    • had 4 weeks off over xmas and well did some stuff to the shed and BRZ, well short of is I don't work full time in supercars anymore as of yesterday.........
    • Did you get any down time over Christmas, or have you had any since to play with this? Or have you given up and are trying to get yourself a second hand V8SC instead?
    • A random thought I had just before I hit "Submit on this post". If brake fluid, in a container in my garage that has never been opened goes bad after 18 months, why can I leave it in my car for 24 months in an "unsealed container"... Secondly, some other digging, and brake fluid manufacturers seem to be saying 5 year shelf life... Me thinks there line on 18 months for an unsealed bottle is pretty much horse shit marketing spin. Kind of like how if you drive a car and don't run a turbo timer your turbo and motor will die horribly...   Where I started on this though... Someone (me) started down a bit of a rabbit hole, I don't quite have the proper equipment to do Equilibrium Reflux boiling per the proper test standards. I did a little digging on YouTube, and this was the first video I found on someone attempting to "just boil it". This video isn't overly scientific, as we don't have a known reference for his test either. Inaccuracy in his equipment could have him reaching the 460 to 470f boiling point range in reality. In the video, using a laser temp gun, he claims his Dot3 that's been open in his florida garage for over a year gets to about 420 to 430 fahrenheit (215 to 221c) Doing some googling, I located an MSDS for that specific oil, and from new, it claims a dry boiling point of 460 to 470f. Unfortunately they don't list a wet boiling point for us to see how far it degraded toward its "wet" point. While watching it I was thinking "I wonder what the flash point is..." turns out its only 480f for that specific brake fluid....   As for testing the oil's resistance, I might not be able to accurately do that unfortunately. Resistance level will be quite a LOT higher than my system can read I suspect based on some research. However, I might be able to do it by measuring the current when I apply a specific voltage. I won't have an actual water % value, but I'll have some values I can compare between the multitude of fluids. I'll run some vague calculations later and see if I should be able to read any reliable amount of current. These calcs will be based on some values I've found for other oils, and see how close I'll need my terminals together. From memory I can get down to 1pA accuracy on the DMM. I don't think my IOT Power Tester has any better resolution.    
    • No, with a twin plate clutch flywheels and clutch pressure plate/friction disks go together. Only clutch where that isn't the case is the Uniclutch but they currently don't make a pull version for the Getrag R34, just some other cars. Personally the flywheel is as light as I'd want it to be. It already drops revs faster than I want to shift normally and I blip the throttle again to rev match on upshifts.
    • Are there any other lighter flywheels that can be used with nismo coppermix twinplate system? Id like to gave the revs pick up faster than oem
