shell in caloundra has it to, i use it and it makes a bit of a diffrence, its pretty good on econnamy i get about 300 ks from about 32 litres

It's pretty rar that they actually have it in stock though, i used to travel to caloundra pretty much every day and sometime's they'de not have it for a month. I don't travel down the way much anymore but with my previos experiences they have it abot 50% of the time. Now what i wanna know is why doesn't the shell in mooloolaba have it?!?!?!

Yeah, it doesn't make much of a difference if you're not tuned for it.

I was getting a wonky idle out of it when cold, used to run right down on the 600RPM stall line, drop down below it and cause the anti-stall to kick in.

Back to 95 till I get an ECU

You can notice a difference, you can feel it ' seat of the pants ' wise easily enough.. i could feel it both on the power fc and the stock gtr ecu

Yeah I had my tune done on this 100octane stuff...

Ran at willowbank a full quarter mile and got no higher than 20 knock levels which is fine, considering you rev to redline for 4 gears before your over the line.

Then two or three weeks later I ran there again with just 98 ron and got knock levels up over 80 which is really really bad, also fouled the plugs.

Has nothing to do with the fuel being bad, its all to do with the tune the pfc had and the fact we were able to push the timing a we bit more advanced with 100ron.

Im considering having a touch up tune just running 98 ron, and putting another degre on the cams to see if I can maintain 337rwkw on 98ron fuel.

Rather than having to put 100ron to get that power level, however last dyno day we got 300rwkw from 98ron on just 18psi so its allot of effort to push for that extra 10% power but when you get into 4th gear down the quarter and your car becomes like a flying phone book you need all the power you can get to reach the line is a fashionable manner. :wave:

Will be interesting to see! But certainlly wont be buying 100ron until Shell make it a more reasonable price... And they wont until a competitor bring in some competition...

yeah i usually fill up with v-power (98), but the other night i had a go with v-power racing (100) becuase the shell at runcorn had been out of the regular v-power for like a week and i refuse to put in anything lower than 98 in my car. anyway noticed the difference right away. much smoother in accel and at top end speeds. i would get this all the time but 1.45 is a bit much for my budget to cope with every week

    • Very nice - I also have a 92 GTST and hardly see any others around these days
    • When I need something else to edit, I use Movavi. A friend who does video editing on a daily basis recommended me) it's an easy video cutter to use for beginners
    • I need to edit some videos for work but I'm not good at all this. Which video editor can you recommend?
    • I think you're really missing the point. The spec is just the minimum spec that the fuel has to meet. The additive packages can, and do, go above that minimum if the fuel brand feels they need/want to. And so you get BP Ultimate or Shell Ultra (or whatever they call it) making promises to clean your engine better than the standard stuff....simply because they do actually put better additive packages in there. They do not waste special sauce on the plebian fuel if they can avoid it. I didn't say "energy density". I just said "density". That's right, the specific gravity (if you want to use a really shit old imperial description for mass per unit volume). The density being higher indicates a number of things, from reduces oxygen content, to increased numbers of double bonds or cyclic components. That then just happens to flow on to the calorific value on a volume basis being correspondingly higher. The calorific value on a mass basis barely changes, because almost all hydrocarbon materials have a very similar CV per kg. But whatever - the end result is that you do get a bit more energy per litre, which helps to offset some of the sting of the massive price bump over 91. I can go you one better than "I used to work at a fuel station". I had uni lecturers who worked at the Pt Stanvac refinery (at the time they were lecturing, as industry specialist lecturers) who were quite candid about the business. And granted, that was 30+ years ago, and you might note that I have stated above that I think the industry has since collected together near the bottom (quite like ISPs, when you think about it). Oh, did I mention that I am quite literally a combustion engineer? I'm designing (well, actually, trying to avoid designing and trying to make the junior engineer do it) a heavy fuel oil firing system for a cement plant in fricking Iraq, this week. Last week it was natural gas fired this-that. The week before it was LPG fired anode furnaces for a copper smelter (well, the burners for them, not the actual furnaces, which are just big dumb steel). I'm kinda all over fuels.
    • Well my freshly rebuilt RB25DET Neo went bang 1000kms in, completely fried big end bearing in cylinder 1 so bad my engine seized. No knocking or oil pressure issue prior to this happening, all happened within less than a second. Had Nitto oil pump, 8L baffled sump, head drain, oil restrictors, the lot put in to prevent me spinning a bearing like i did to need the rebuild. Mechanic that looked after the works has no idea what caused it. Reckoned it may have been bearing clearance wrong in cylinder 1 we have no idea. Machinist who did the work reckoned it was something on the mechanic. Anyway thats between them, i had no part in it, just paid the money Curiosity question, does the oil system on RB’s go sump > oil pump > filter > around engine? If so, if you had a leak on an oil filter relocation plate, say sump > oil pump > filter > LEAK > around engine would this cause a low oil pressure reading if the sensors was before the filter?   TIA
