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.

Tried v-power once in the gtr after using it for 3 years in the silvia and it ran like shit... ultimate it runs great. loves ultimate + octane booster though or just v-power racing but we dont have that up central qld way.

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

    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.   
    • My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.
    • Awesome, thanks for sharing!
    • To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
    • So, now all you need to do is connect the 2 or 3x 12v feeds into the unit to permanent 12v, ACC 12V and IGN 12V that you can find in the spot behind the stereo, and the earth, and then it will switch on with the car.
