So I changed to a brand new stock balancer and yep, it's as good as new. no more harmonics or thrown belts.
Ross one is getting sent back to find out what happened to the dampener, whether it has de-lammed or something else.
wow. good enough for me - I know my mind is made up now.
Thanks for posting.

Ask him where his car is
haha! you're a jerk you know that?!
(good call - I would do the same....)

Did you say you 'balanced' the Ross Damper? I don't think you should have to - it should be balanced from factory.
Also - if you can feel very noticeable vibration - even free revving, then I wonder if you haven't got something more serious going on.
FWIW, I couldn't 'feel' anything wrong with my engine - it just kept blowing power steering belts off (and now the cambelt)
Sure will be interesting though if a stock balancer fixes it.
-
sounds like a clever install that's all. might save someone going to the lengths I have?
-
yes same, running Autronic disc inside the CAS.
hmm.. trigger wheel on the front side of the timing gear? Interesting - got any pics?
-
Hi Brad,
We're using the CAS for sync - so don't require a missing tooth.
-
Trigger wheel done - 24 teeth.
I have a couple of spares of these if anyone wants one down the track.
Great job done by the guys at Highspeed.
-
Yeah which then turns into a "how fat are you - and was the tank full?"
.....its why when I'm serious I always let my girlfriend drive... half a second right there.

Standard weight 32 or 33 GTR / GTST that runs 129-130 mph has 400rwkw
That's based on everything from 1400-1450kg (3100-3200lb)
@ 1550kg (3400lb) it needs to be about 125mph
And lets not forget.. Driver could be anywhere from 70kg through to 120kg.. Tanks of fuel or empty changes things by another possible 50kg..
(not disagreeing with you by the way - just pointing out even this has a bearing on it)
-
haha.. just make sure you put all the E85 in the tank............ no 'little umbrellas'
-
..mate I don't know if you're sending the right message to all the young people out there...
-
Yeah get yer clamp meter out Paul... or stud finder.. or something...
-
Naw wouldn't go that route either. I have a 500R on my 'mini-me' version of Paul's and mine has break-down once it's hot.
Is that not more likely coils then? What coils were you driving with the 500r?
-
-
Sounds good Paul! Looking forward to the end result!
What did you end up doing for the other -5 ?
-
Last time I had that problem I was in a lot of trouble with her father....
I don't have the little rubber on my cover.
-
maybe the noise the oil trying to get the F out of there!
-
Im wondering if anyone knows what the piston sizes are?
and what the surface area of the pads area?
..............and cue - Roy - <enters stage left>

Nice, now if you could get it to work 100% with the ROSS hall effect sensor bracket that would be sweet.
Yep. That is exactly my intent. Shouldn't be very hard at all.
-
Don't take the shine of my day by asking a question like that mate....!
($850 - inc post, and including the Oversize Water Pump Pulley - essentially this is model #917753)
Obviouly its going to cost me for the CNC Trigger wheel as well - so all up not cheap, but custom one off never is I guess.
-
Just in case anyone is interested, I've had ATI make me a custom balancer with provision for adding a chopper wheel to the back of it. Gives me the flexibility to configure diameter and number of teeth/configuration etc.
I have tech drawings too if anyone needs one. Going to go and have a chopper wheel CNC'd to suit and I'll post that up later when its done.
Below I've shown the back of my original 1000hp ATI balancer, and then the back of the new one. You can see I've simply had them add material back and provide six threaded holes.
-
Also, what is the gain with running an aftermarket balancer. Never been clear to me
well worth the read if you're interested.

Well, I think the 'promise' is that the aftermarket damper (it is not actually a balancer lets remember) is to provide more/better damping that the original damper was designed for. Thats why you often see them rated via horsepower as this is some indication of the amount of 'twist' a crankshaft can experience on a modified engine.
I spoke to ATI at SEMA last year and they were adamant that if I was pushing 600+ hp then I should be using the larger 7" body rated to 1000hp. Now of course there is always the marketing side. ATI do hold some patents though and if you read them it sounds quite plausible about how it works and why it is better.
The problem any of us have is that it is not measureble (easily). You can see the results of a bigger turbo on Dyno, or a better radiator via the temp gauge etc.
When a damper throws a belt that was not being thrown before (all else being the same) then I wonder if the harmonics are not being dampened as well as they should be and the 'gauge' is the belt flying off ! (or the oil pump breaking etc)
To fit an idler pulley solves in part the 'symptom' of the belt coming off - but has it fixed the underlying, more important issue?
Hence I think a standard damper is probably a better option is cases where we just don't know. But - ATI are used on just about all NASCAR engines etc too... and I've seen charts of their harmonic damping actually tested. So!! I don't know.... : /
-
Same as the green thing really, a good allrounder just with 4wd and a bit more power!
It's got some cool fruit already including a full T88 kit but I'm going to downgrade the turbo to something more suitable
Weeeelll, well. Looks like I won't be giving any head starts at Powercruise after all. Finally bringing a gun to the knife fight mate!

Glad to hear there is some progress now Paul.. I need some motivation to get back onto mine. Looking forward to seeing this over the next coupla weeks mate!
