hey guys got a s1 rb25det and i am rebuilding it and i want to do it once and right. ive read a bit and i see that harmonic balancers suprisingly play a big role in motors. so i have looked up ross balancers but i dont think they do rb25s???

what brand do you reccomend and who sells them at good prices. im in bris but i dont think it matters where i get it from as i can just get it posted.

yes i did search but im retarded and probably went right past this exact thread. sorry if that the case haha.

cheers, Steve.

Hey Steve,

What brand... ATI http://www.atiracing.com/

Where to get one...

Aussie Stock, if you want it soon

CJ motors - contact Jackie

If you dont mind the wait..

Summit Racing

Horsepowerparts

You can run a Rb26 balancer on your Rb25 but it will require a few mods. see below..

well 380 from nexus or 540 from high octane. though the ones from nexus say they are made from the ross machine wich is what hi octane sell.

what to do.....

Edited by old mate

well there is word that the current ross balancers are better. but I can count a number of people I know personally who had a ross and stopped using it in favour of an ATI. I know 1 case where the guy had a ross, had it replaced with a newer model ross and still had to go to an ATI in the end. yes the ATI cost more, but I guess it's a case of getting what you pay for.

the precision parts ones look good but I have no experience with them. if you are really hard core consider a garage saurus crank pulley. they are solid, no rubber. but supposedly if engine is balanced well they are a good way to go.

what was the reason/s he/they stopped using the ross ones? no point saying they are crap and the ati ones are far superior if there arent any real reasons

thrown balancer and stuffed 7K crankshaft...now runs ATI and has been faultless...over 1150AWHP

i can get a few things from the above...

crank bolt came lose - who didnt do it up/put it on properly?

crankshaft snout out of round/out of tolerance - who didnt check crank/balancer tolerance?

balancers dont just come off by themselves

or is there something else that happened?

you can guess or make asumptions...here are some things that "are" known...the workshop in question has built almost all of australia's highest powered GTR's up until a few years ago...they own a 2 metre long torque wrench to do all their balancers up. This was the 1st time they have used a Ross balancer, they use the correct process to install them, they have never had a problem in the past and have never had an issue since, the crankshaft was a brand new full counterweight item. This was the older style Ross item which was little more than a glorified pulley for the belts. I understand that Ross since then have changed their design.

i was in the same boat choosing a harmonic balancer a few weeks back, some ppl here dont like ross yet www.ripsracing.com use these on all of their street and drag engines including their drag 1300hp donks, that confirmed my decision. fyi, rips build and ship engine packages all over the world.

i think the above mentioned failure was a factory fault...for example, my dad bought a torana ss 5.0ltr and it spun a bottom end bearing after a few yrs. do we draw from this incident that all toranas are unreliable? no smart ass comments :nyaanyaa:

i dont really care who did it, how they did it all im interested in is how it was 'thrown off'. i dont understand pauly, explain it better please

    • I know why it happened and I’m embarrassed to say but I was testing the polarity of one of the led bulb to see which side was positive with a 12v battery and that’s when it decided to fry hoping I didn’t damage anything else
    • I came here to note that is a zener diode too base on the info there. Based on that, I'd also be suspicious that replacing it, and it's likely to do the same. A lot of use cases will see it used as either voltage protection, or to create a cheap but relatively stable fixed voltage supply. That would mean it has seen more voltage than it should, and has gone into voltage melt down. If there is something else in the circuit dumping out higher than it should voltages, that needs to be found too. It's quite likely they're trying to use the Zener to limit the voltage that is hitting through to the transistor beside it, so what ever goes to the zener is likely a signal, and they're using the transistor in that circuit to amplify it. Especially as it seems they've also got a capacitor across the zener. Looks like there is meant to be something "noisy" to that zener, and what ever it was, had a melt down. Looking at that picture, it also looks like there's some solder joints that really need redoing, and it might be worth having the whole board properly inspected.  Unfortunately, without being able to stick a multimeter on it, and start tracing it all out, I'm pretty much at a loss now to help. I don't even believe I have a climate control board from an R33 around here to pull apart and see if any of the circuit appears similar to give some ideas.
    • Nah - but you won't find anything on dismantling the seats in any such thing anyway.
    • Could be. Could also be that they sit around broken more. To be fair, you almost never see one driving around. I see more R chassis GTRs than the Renault ones.
    • Yeah. Nah. This is why I said My bold for my double emphasis. We're not talking about cars tuned to the edge of det here. We're talking about normal cars. Flame propagation speed and the amount of energy required to ignite the fuel are not significant factors when running at 1500-4000 rpm, and medium to light loads, like nearly every car on the road (except twin cab utes which are driven at 6k and 100% load all the time). There is no shortage of ignition energy available in any petrol engine. If there was, we'd all be in deep shit. The calorific value, on a volume basis, is significantly different, between 98 and 91, and that turns up immediately in consumption numbers. You can see the signal easily if you control for the other variables well enough, and/or collect enough stats. As to not seeing any benefit - we had a couple of EF and EL Falcons in the company fleet back in the late 90s and early 2000s. The EEC IV ECU in those things was particularly good at adding in timing as soon as knock headroom improved, which typically came from putting in some 95 or 98. The responsiveness and power improved noticeably, and the fuel consumption dropped considerably, just from going to 95. Less delta from there to 98 - almost not noticeable, compared to the big differences seen between 91 and 95. Way back in the day, when supermarkets first started selling fuel from their own stations, I did thousands of km in FNQ in a small Toyota. I can't remember if it was a Starlet or an early Yaris. Anyway - the supermarket servos were bringing in cheap fuel from Indonesia, and the other servos were still using locally refined gear. The fuel consumption was typically at least 5%, often as much as 8% worse on the Indo shit, presumably because they had a lot more oxygenated component in the brew, and were probably barely meeting the octane spec. Around the same time or maybe a bit later (like 25 years ago), I could tell the difference between Shell 98 and BP 98, and typically preferred to only use Shell then because the Skyline ran so much better on it. Years later I found the realtionship between them had swapped, as a consequence of yet more refinery closures. So I've only used BP 98 since. Although, I must say that I could not fault the odd tank of United 98 that I've run. It's probably the same stuff. It is also very important to remember that these findings are often dependent on region. With most of the refineries in Oz now dead, there's less variability in local stuff, and he majority of our fuels are not even refined here any more anyway. It probably depends more on which SE Asian refinery is currently cheapest to operate.
