yeah a lot of cars have around 20-30rwkw.

you notice it alright because its due to the added timing etc, so not just outright power, power all through the rev range

Ah BS, I had close to another 25rw/kw added to mine and I coudn't even tell, you're doing VERY well to notice 20 killer wasps I tell ya now. :D

I give it another 2 years until they start phasing out 98 ron :D

I don't think so - alot of performance and euro cars need 98 fuel.

- But you "could be" possibly onto something, one way of masking detonation is to add more ethanol to 95 fuel - Which is crap as this is ethanol has a lower BTU and we are all still paying the same price at the pump :)

BB - try here:

Benno - can you confirm that this is good as the shell product.....do you recommend a retune?

"premium100 is currently only available in Albury & Bayswater in Victoria. "

Bah, it was so handy when it was 10 minutes drive away. Why Albury?????

I reckon a re-tune would be needed as it would run leaner given the 3.55% oxygen content, not to mention specific gravity differences (fuel mass etc).....

At least its going to be next year before we need to worry.

PFC users if you cant find 100ron and your tuned around 100ron you can use the temp IGN adjust to back out say 4 to 5deg IGN timing

this should stop the main bulk of detonation on full load when using 98ron fuel. i would only use this as a temporary measure (hence the term "temp ign adjust") and get it retuned properly. the temp ign adjust feature is covered in the PFC FAQ and it resets itself when you power the car off (so you need to set it each time).

Wow my track days just went up by $400. Fark dat!!!

Looks like a trip to Bayswater every track day is in order to get united 100. I know my car was tuned on it so there is noting wrong with the stuff.

Only problem is I bet united follow suit with shell. Which is going to leave sunoco at $7 p/l looking like a fair option :(

Only problem is I bet united follow suit with shell.

With all the fuel sharing going on I wouldn't be surprised....however Shell lists the eth content as 5% whereas United lists theirs as 10% so maybe they are different fuels.

bad news is united is 72km round trip for me :P

its good.. similar to VPR. but has 5% more ethanol so the AFRs will be a little leaner hence need to retune atleast the fuel mixtures (esp if you are running close to 12already)

i am running mobil98 right now. its good.

This really sux.

My GTR is tuned for 100 RON V Power Racing and it is far more responsive than any of the 98 options around.

Looks like I will have to go back to BP Ultimate and a trip to the dyno for a re-tune.

    • There's plenty of OEM steering arms that are bolted on. Not in the same fashion/orientation as that one, to be sure, but still. Examples of what I'm thinking of would use holes like the ones that have the downward facing studs on the GTR uprights (down the bottom end, under the driveshaft opening, near the lower balljoint) and bolt a steering arm on using only 2 bolts that would be somewhat similarly in shear as these you're complainig about. I reckon old Holdens did that, and I've never seen a broken one of those.
    • Let's be honest, most of the people designing parts like the above, aren't engineers. Sometimes they come from disciplines that gives them more qualitative feel for design than quantitive, however, plenty of them have just picked up a license to Fusion and started making things. And that's the honest part about the majority of these guys making parts like that, they don't have huge R&D teams and heaps of time or experience working out the numbers on it. Shit, most smaller teams that do have real engineers still roll with "yeah, it should be okay, and does the job, let's make them and just see"...   The smaller guys like KiwiCNC, aren't the likes of Bosch etc with proper engineering procedures, and oversights, and sign off. As such, it's why they can produce a product to market a lot quicker, but it always comes back to, question it all.   I'm still not a fan of that bolt on piece. Why not just machine it all in one go? With the right design it's possible. The only reason I can see is if they want different heights/length for the tie rod to bolt to. And if they have the cncs themselves,they can easily offer that exact feature, and just machine it all in one go. 
    • The roof is wrapped
    • This is how I last did this when I had a master cylinder fail and introduce air. Bleed before first stage, go oh shit through first stage, bleed at end of first stage, go oh shit through second stage, bleed at end of second stage, go oh shit through third stage, bleed at end of third stage, go oh shit through fourth stage, bleed at lunch, go oh shit through fifth stage, bleed at end of fifth stage, go oh shit through sixth stage....you get the idea. It did come good in the end. My Topdon scan tool can bleed the HY51 and V37, but it doesn't have a consult connector and I don't have an R34 to check that on. I think finding a tool in an Australian workshop other than Nissan that can bleed an R34 will be like rocking horse poo. No way will a generic ODB tool do it.
    • Hmm. Perhaps not the same engineers. The OE Nissan engineers did not forsee a future with spacers pushing the tie rod force application further away from the steering arm and creating that torque. The failures are happening since the advent of those things, and some 30 years after they designed the uprights. So latent casting deficiencies, 30+ yrs of wear and tear, + unexpected usage could quite easily = unforeseen failure. Meanwhile, the engineers who are designing the billet CNC or fabricated uprights are also designing, for the same parts makers, the correction tie rod ends. And they are designing and building these with motorsport (or, at the very least, the meth addled antics of drifters) in mind. So I would hope (in fact, I would expect) that their design work included the offset of that steering force. Doesn't mean that it is not totally valid to ask the question of them, before committing $$.
