hi guys,

my gtr is tuned for bp ultimate but after reading this article which 'maybe' motec has an affiliation with shell but i dont really care about that...

www.motec.com.au/fueltest/results.htm

...i am now tempted to get a retune on shell vpower.

i did a search & found some good info here - out of interest what is the preference fuel used here on a modified turbo?

fyi im running 325awkw.

thanks,

thank your fkn lucky stars you can get vpower. its "out of order" everywhere i have seen in sydney for months now. so i have to make 10minute detours to find 98 octane caltex or mobil. its a fkn joke, god knows what the explanation is.

in regards to your actual query though, i really dont think there would be discernible difference between bp and shell. all i would say is go to a high traffic servo because they have fresher fuel.

fresh is best!

that said, i loved vpower, and never had any trouble with it WHEN IT WAS AVAILABLE!

fkrs!

Hold on a sec, the article talks about V power racing (100 octane with some ethanol) and your talking about Vpower (98 octane)?

They're different things, one costs more and is extremely difficult to find :)

My tuner recommends a 100 octane fuel for track days so thats what I used last time, but I use BP ultimate for day to day and its been fine.

bp ultimate is my trusted fuel for both my rb20det and 26dett... both have never missed a beat and run perfectly... when i was in landscaping i also used ultimate in my honda mower and whipper snipper both been 4 strokes and they had alot more punch...

ultimate ftw! :)

happy easter

In my GTS-T daily driver I have used both Shell V-Power and BP Ultimate and it runs better on the BP Ultimate and I even get better fuel enonomy as an added bonus.

In my GTR I run Shell V-Power Racing (100 Octane) because the GTR loves it and she is more responsive right through the rev range. This stuff is hard to get and it costs more but for a limited use car it is worth the extra hassle and extra cost.

Both are very hard to find in Canberra atm, but I currently running tests on all 98 and found Ultimate gives the best fuel consumption, next Shell and last by far is Caltex. Not many Mobil's in Canberra

my r33 gtst auto is tuned to 320rwkws on shell v power.

knock levels on the pfc never go above 15, at 24psi boost.

due to running low on fuel i pulled into a bp that is a very high use servo and filled up with

ultimate. first time i opened it up after that i seen the dash light flash, and backed off, resulting in a knock of 76.

shit.

i thought suerly that cant be fuel related, so a few das later i opned it up again to 19 psi and straight away i had knock up to the low 80's. the rest of the tank was used up with less then 5 psi boost.

a fresh load of v power, and all happy again straight to 24 pound with knock in the low teens.

enough said i think.

havent touched it since.

yeah the 100 octane v power racing is a great detonation killer

We only have the 98 vpower here in Adelaide. :rofl:

Im keen to check out the difference between the two fuels once/when I eventually run some decent boost; especially considering loonyman4 runs on the same dyno as I. :D

oh ok - my bad

well in vic we have 100ron v power racing its great

i have it on tap at my local shell 5 seconds from my place

and the price of it changes about once a month if that, my local shell had it at $1.59 for about 1.5 months

ive been using it past 2 months now

in summer with massive intake temps, exposed pod, aggressive timing

full load run uphill on a freeway on ramp - knock of like 10 is the most i see

if i had 98 in it it knocks around 60+ ish

      Much less twat-tastic. CF wheels are too garish for civilised use.

      From there, as the manual says....assembly is the reverse of disassembly, no tricks worth mentioning Much better (for me)

      In my case, the standard wheel I had was in good condition but the buttons had more wear, so I swapped them across from the original wheel from the car. The plastic rear cover is held on by 4 tabs, and once the wiring is removed you can get access to 2 screws on each side the hold the buttons in From there I just swapped the wiring over. What was interesting is the standard style wheel is 2.0kg but the carbon fibre one is 50% heavier at 2.9kg. It even has a weight inside the wheel at the top to make up for some sort of imbalance in the design. weird

      Once the airbag is off, to remove the steering wheel.... Undo the 2 plugs into the clock spring, and the horn connector from it's clip. Hit the 19mm nut with a rattle gun (preferably) or if you don't' have one, you probably want an assistant to hold the wheel in place while you use a breaker bar to undo the nut Then, screw the nut back on 3 turns, and pull the wheel sharply towards you. If that doesn't work hit it medium force with a rubber mallet on either side, or possible behind if you can get there. If that all fails (it shouldn't!) you might need a steering wheel puller

      So, to next task....the carbon fibre steering wheel was either an expensive factory option or a chinesium special. Either way, I don't like either the flat bottom or thick ring style, so it had to go So...to remove the steering wheel.... First, disconnect battery negative and stomp on the brake pedal for a few seconds. Then, remove the small circular covers on each side of the wheel's rear surround to uncover the airbag clips. You need to push something like a flat bladed screw driver through, to push the steel clip inwards and pull the side of the airbag forward. Once you've done the easy side, same on the centre console side. You can see the tab you are shooting for circled in red Then, disconnect the horn spade connector and for the yellow airbag plug you need to get something small under the black locking tab to pop it out, then the connector releases......airbag is off
