R33Turbo Posted May 15, 2008 Share Posted May 15, 2008 V-power & V-power racing is back! And isn't as expensive as BP Ultimate which is a good thing for me cuz i go coles for shopping as well which gives me those receipts for d/c By the way is it effective putting in v-power racing into our skylines as imports are tuned for 100RON unleaded from factory? Or does v-power racing require separate tuning? Link to comment https://www.sau.com.au/forums/topic/219377-shell-v-power-is-back/ Share on other sites More sharing options...
Primordial Posted May 15, 2008 Share Posted May 15, 2008 Running on 100ron will decrease your chance of detonation. If your car has been tuned properly on 100 then you may get a marginal increase in power and mileage. You dont NEED to have your car tuned to run 100, its just that its probably not worth the extra money unless your car's been tuned to take advantage of it. Be warned though, if you tune your car on 100ron it'll be less happy when you inevitably have to put 98 in it! Thats just my "2c"... Haha... get it? Ok that was a shit joke...

Ok that was a shit joke... lol whys it always 2 cents? there was a 1 cent as well u know? anyway WOOHOO! V-POWER IS BACK!

HuH Posted May 15, 2008 Share Posted May 15, 2008 The advice I was given reagrding 98RON fuels, was that V-Power is actually one of the lowest quality ones available. BP's Ultimate, Caltex's Vortex 98 and even the Mobil 8000 were all ranked better by my previous mecahnic? I say previous because he doesn't service the Skyline, only my Mini Cooper (which is now sold). He was referring specifically to using the fuel in the Mini, but that shouldn't really impact on his opinion of the fuel in general. He's someone who's opinion I hold in quite high regard and I do trust, but it does conflict with what I've heard other people saying? Anyone got any input on this?

R33Turbo Posted May 15, 2008 Author Share Posted May 15, 2008 Well the only backup ive got for V-power fuel are my air-fuel ratio on from dyno. The air-fuel ratio was REAL GOOD using V-power fuel. but then again most effective way is for a power fc to detect the level of knocks on different fuels i think?

Clappa Posted May 15, 2008 Share Posted May 15, 2008 I was actually surprised with the fuel price last night. Mobil in Epping was selling Unleaded for 1.37L..Cheap. I still went to pennant hills though and put V Power in my SS. For some reason, it justs likes V Power better. Either way, V Power is back..Woo hoo...

e_Dog Posted May 15, 2008 Share Posted May 15, 2008 thank god....i had gotten tired of asking the nob's at the local shell station when it would be back and have them answer "very very soon.....would you like two Mars Bars for $1.50....no....ok come again" Link to comment https://www.sau.com.au/forums/topic/219377-shell-v-power-is-back/#findComment-3870782 Share on other sites More sharing options...
DECIM8 Posted May 15, 2008 Share Posted May 15, 2008 V power is the second highest rated performance fuel, I dont think you mechanic is on the right page!! Caltex is number one, 1KW ahead.

SL33KY Posted May 16, 2008 Share Posted May 16, 2008 So... Which is better performance/fuel pump wise? V-Power or V-Power Racing? A while ago I was hearing a few stories of people using the V-Power Racing and it was screwing with their fuel pump, can anyone verify this? I use the BP Ultimate... I just want what's best for my baby lol Link to comment https://www.sau.com.au/forums/topic/219377-shell-v-power-is-back/#findComment-3871309 Share on other sites More sharing options...
Primordial Posted May 16, 2008 Share Posted May 16, 2008 Higher octane fuel is denser than regular fuel, so if your fuel pump almost dead anyway then it might make it struggle to the point that it dies completely. Othewise the high octane fuel/fuel pump thing is bollocks. Also being higher density means that the car runs richer. If your car is running rich to start with then it may not be beneficial at all to make the car run more rich. As i said before, if you're car is tuned for 100 ron then it takes advantage of the lower chance of detonation and allows you to run a more aggressive tune = more power. At the end of the day, its only 2 ron points so its not going to be a huge difference anyway!

It is a similar situation for V-Power (98) and the 5% ethanol blended V-Power racing (100 octane).

Primordial Posted May 16, 2008 Share Posted May 16, 2008 Yeah you're right, ethanol lowers the energy density of the fuel. I forgot 100ron is 2% ethanol. Higher octane petroleum is higher in density than its lower octane counterpart though. Here's some interesting results on the potential power gain by using 100ron: http://www.racefuels.com.au/dynoDetail.asp?ID=59 It looks like about 3.5% peak power gain, and 4.8% peak torque gain between 98RON and 100RON Shell fuel... Keep in mind that they advanced the tuning by 2 degrees and leaned the AF ratio to take advantage of the better fuel so I wouldnt be expecting to get anything near these results without tuning or at least a car with active knock sensors.

Yeah people get trapped and stooged to a degree. Trapped because fuel is added to the engine in volume not by weight. So a less dense fuel can will give you a higher AFR. Add oxygen in the fuel & you can get yourself in trouble. Wonderful thing if tuned properly, however. Stooged because you buy fuel by the litre not the kg. So your less fuel efficient E10 (measured in km/litre) costs more than it should.
