markimak Posted June 19, 2007 Share Posted June 19, 2007 the ethanol is good in a way, as it cleans everything in the engine as it gets passed through. Its almost as good as having water injection except its in the fuel. However because its partially made up by ethanol the fuel isnt as dense and it also burns leaner, so when being tuned it needs to be richened up abit in comparison to normal fuel. By all means you should get a little less economy from a tank because of this. However it does have a higher octane rating, so it sort of works itself out. Think of it like methanol, it burns lean and cold, thats why you need to squirt 2.2 times as much over std fuel. But the octane rating of it is astronomical.Thats how i see how the ethanol helps, whether its right or not is beyond me. methanol octane is about 128, ethanlol is about 126. the only down side to a higher octane is that it makes it harder to ignite, that is why you can advance the timing with them. pretty much sums it up. ethenol reacts with water and moisture.. it can have some side effects. with the amount of carbon deposits we all have in our engines its prob best u run a tank everyonce in a while.. i hope everyone changes ther fuel filter regularly..?

SMR33 Posted June 19, 2007 Share Posted June 19, 2007 edit: are all v-power's 100 octane?? V-Power is 98 and V-Power Racing is 100 (also contains 5% ethanol). So at the very least you filled up with 98.

At least people know where to get this fuel now.

pear Posted June 20, 2007 Share Posted June 20, 2007 I'm a little surprised at the price. I visited Virginia Shell today. approx prices - Regular Unleaded $1.14, V-Power $1.24, V-Power Racing $1.44 with 5% ethanol I would think that VP Racing shouldn't cost 30c more than regular unleaded. Other lower octane ethanol based fuels are cheaper. question for the fuel techs, would BP 98 or Caltex 98 with an octane booster (ocasional use) be better than the ethanol additive? Does anyone use octane boosters? Link to comment https://www.sau.com.au/forums/topic/173152-v-power-racing-fuel/page/2/#findComment-3190070 Share on other sites More sharing options...

J-Boy Posted June 20, 2007 Share Posted June 20, 2007 Just use BP98 or stick to wotever fuel yer car is tuned with. With octane boosters, only thing is that it screws up the internals of the cat, so it will melt down the internals of the cat and eventually block up the cat, and then u have to replace yer cat.

Einstein Posted June 21, 2007 Share Posted June 21, 2007 shell employee signing in for some reason (i believe it's supply issues, if anyone noticed the 2 week dry spell a month ago) the racing pricechanges dont come through with the other fuels anymore at the moment it's sitting at about 145, and hasn't changed for a week or more now so i'd say it's not going to change for a while until they fix their supply problems but shrug, i just work there, i have no idea of how pricing actually works, we just get told when to change it and what to =P Link to comment https://www.sau.com.au/forums/topic/173152-v-power-racing-fuel/page/2/#findComment-3190924 Share on other sites More sharing options...
Russco Posted June 21, 2007 Share Posted June 21, 2007 nulon pro strength octane booster and bp ultimate at the correct mixture will bump your octane rating up to over 100 (around 103) Even using the above it didn't match Shell 100 in my car, safely ran more ignition timing + another 4psi with Shell 100. I actually spoke to one of the techs at Nulon and he said 98 ron + prostrength will make a 98.9 ron mix (from memory) - the increase wasn't huge. Shell 100 is a much better brew......if they have it in stock.

J-Boy Posted June 21, 2007 Share Posted June 21, 2007 Octane boosters will never be as good as a pure race fuel or 100 octane fuel. I've tested this vpower racing out on both my previous r33 gts-t and my current gtr32, and i have to admit, it runs good, especially since my gtr is tuned in Japan with much higher octane.

Does anyone use octane boosters? i like ethanol i think it is a great introduction.. fingers crossed we will be able to run off it more soo as fossil fuels are depleting quickly octane booster no.. injector cleaners.. are good though Just use BP98 or stick to wotever fuel yer car is tuned with. With octane boosters, only thing is that it screws up the internals of the cat, so it will melt down the internals of the cat and eventually block up the cat, and then u have to replace yer cat. yes i agree, to stick with the same octane fuel as tuned.. unless ther car is constantly learning and adapts to different fuels..? melt cat.. lol as if u would use a car..

Shell 100 is a much better brew......if they have it in stock. all i know is that my mate got a hold of an octane tester, and they were the results. the abbility to run more ignition timing with the shell fuel is because of the ethanol. it burns colder, and less explosive. to get the same sized explosion with ethanol as normal petrol you need to use nearly twice as much. ethanol also takes more spark to ignitite. if you were to run a normal street car tuned for 98 ron fuel on pure ethanol it would run like crap. it would be majorly down on power. the ideal afr for ethanol is around 6:1, and it is much harder to ignite. you would have to advance the timing by over 10 degrees. my mate runs c16 in his drag/street car. when he is running the c16 he advances the timing by 10 degrees.
