on 98 (ultimate/optimax) previously had to pull boost back a touch to prevent higher knocks,

on 100 (extreme/Vpower racing) have been able to re-up boost to as previous yet rarely get a high knock.

(pfc is still tuned to 98 fuel as would hate to get stuck in stix with wrong tuning to fuel available.)

works for me,

im pretty sure its now called v-power coz thats what its called in europe. sort of a would wide standard.

ps. anyone ever read the "new unleaded" brocher where it "gets you further"

down the bottom it says in a small disclaimer that the fuel used during the test is "diferant" from what is curently available localy lol so yah it doesnt get you further lol

i have a question - I pumped up with v-power today (had a quarter tank of ultimate left). Came to about 33 ltrs - but then it only came to 3/4 tank full :(

would there be something to do with expansion of the fuel or is it just that my guage is stuffed? Im guessing my gauge is stuffed.

Yeah sounds like the gauge is stuffed. Did your fuel light come on though?

nah cos i filled it up when there was quarter tank of petrol....its just wierd - i will see how it goes when i fill it next time (if i get to fill it before my next service). I do know that skyline fuel gauges are notorious for being faulty.

With your head work, have you run it up on the dyno?

Have you found higher power figures, different boost curve, faster or slower to boost, better or worse economy and response?

Thanks

Hi, not on the dyno, I am road tuning it. At the moment, with the standard turbo, I have 10 psi at ~2,000 rpm because of the ignition advance I can use, +18 degrees (compared ot the default maps) at many load points. As a result the response is lightning fast.

As for ecomomy, it happily runs 15.1 to 1 A/F ratios at cruise (open loop), with absolutely zero hesitiation or surge. So I can confidenmtly change the lambda aim table when I turn closed loop back on.

:( cheers ;)

SK. So headwork is a good option on a car, if for instance you are bored and want to pull the head off and have get it tidied up?

You won't loose any grunt?

without changing valves and all that, do you see it as a good thing to do once you have done turbo, injectors etc etc.

How does it go on the $ / results graph?

Just going back to the title of the thread for a second while we wait for God to respond... I used some of this fuel on the track the other day.

I was expecting to be able to put some more ignition timing in it but knock levels didn't decrease with the change of fuel so I left it alone. I felt maybe 5 more rwkw. However much is the smallest amount I can feel using the seat-of-the-pants-o-meter.

As postred in the other thread where you asked the same questions

Been using 100 ron in the R33GTST since January (almost 12 months). I put an adjustable FPR in recently to raise the fuel pressure and a GTR fuel pump. I checked the fuel lines at the same time and they are in perfect condition.

:D cheers :D

is it me or why do i still think that my car feels nicer and smoother and 'quicker' on Vortex 98 even compared to V power racing?

Car: R33 gts-t (auto) with basic mods

my best mate with a stock R33 Gts-t Manual has the same opinion?

So have I. seems to be great.

I have a 100RON joint near my house..I only drive the car 1 time per week so the extra cost means nothing to me.

      It was a great, but typical track day, and some VB was ingested at the night time debrief 🤪

      And so, to round this out, I couldn't be happier to confirm @MBS206 has decided to buy the car. He drove down from sunny QLD with a trailer last week and it is off to its new home today. I'll let Matt confirm on next steps but I understand broadly that the plan is to leave it pretty much as is, and just get some quality wheel time with a nicely balanced car that is pretty much track ready. There are a few a jobs still to be done first but nothing too major and I think its a very smart buy Dinner last night at the Paragon with a round of VBs (mostly) for Neil

      Well, 50 pages and the end of a chapter for this car. We took it out for a shakedown at Wakie yesterday, and everything went well. There were a couple of niggles: - Oil cooler fitting leak - tightened, cleaned, stopped leaking - Radiator cap overflow fitting was leaking....Mark called it, the overflow fitting was threaded in and not tight....tightened, tested and held pressure - Small oil leak at the rear of the block, probably the turbo oil feed - too hot to get at it comfortably but probably just needs to be nipped up - leak at the driver's side rear brake line where it meets the hardline. Fitting wasn't loose, so Matt backed it off and back on, no further leaks - there's also a leak somewhere on the top of the fuel tank, maybe that cross over fuel line - that was has been left to fix when its on a hoist Otherwise than those niggles the car went great, turned great and stopped great so it was a very successful day out. I'm always really nervous when a car first hits the track after a long break, especially with a brand new engine as well but it was great. VID-20251011-WA0007.mp4  Big thanks to @The Bogan who dropped by and helped out, @MBS206 and my nephew Lachlan the apprentice.  Neil's wife Mel also surprised the hell out of all of us by dropping by; she's up in Tamworth these days but was travelling to Melbourne so had plausible deniability for turning up at the garage, it was great to see her but also obviously a bit sad all round.

      Unsolicited advice? Keep the engine as close to stock as you can. Nothing wrong with adding some boost and making a little more power, but given where you are, you really don't want to try to make it into a monster. I can't imagine the roads are up to it, and the lack of locla support when it grenades will be a ball ache. FWIW, If there is a dyno around that you can access, then brand new injectors are a good idea, which will lead you to (at least) putting a Nistune in it, which will allow you to put an R35 AFM on it, all of which will make it possible to make it much much nicer to drive and live with.
