I find it interesting that Shell are flogging off race V power with a 5% ethanol blend. Ethanol has an oxygen molecule which means that it has partly oxidised, ad anything that is oxidised has partially burnt. Therefore any fuel that has partially burnt will have less bang for the buck over the pure stuff. You will find tank range will drop with an ethanol blend due to this.
As above, I run everything on BP, usually targeting BP ultimate 98. The 4wd runs on BP diesel as it has a lower sulfur content than the other 3 sisters.
Graham if u run a 4wd diesel why arent u using Militec in it???Hmmmm
Mate u cant go wrong I have 500 ml bottles now, this would do engine ,g/box and diff.
But i need the Money
Hi Ray,
I'll try anything once!!!!
Did you get my PM regarding the brake light microswitch on the brembo caliper. Drop me a line buddy, or catch you Tuesday night.
Regards
Graham

mate I don†t think what you are saying is quite right.......... ethanol is a form of alcohol. Ethanol is essentially a carbon based molecule that looks like this

saying that it is oxidised and hence partly burnt is not exactly right, it is an oxidised for of ethane gas, but no its not burn ethane gas. The major reason that it would be less economical is that it is much much less dense than regular octane (CH3(CH2)6CH3) and is a much smaller molecule.
Advantages of ethanol use are that it is locally produced, the alcohol is produced from Australian sugar cane, it is easily renewable and most of all the combustion of ethanol is H20 (water) and CO2 (carbon dioxide). ethanol combusts completely much more readily than octane and is much much less detrimental to the environment.
I ensure that I run ethanol based fuels in all my work vehicles, but I haven†t tried it in my busa as yet. Most car manufacturers recommend not more than 10% ethanol be used in vehicles (Australian standards reflect this), and I am meant to believe that 5% is safe for the bike. Shell V Power Racing contains 5% ethanol, and I would be happy to give it a go but shell have been selective in their distribution of this product and I have never even seen it!

A busa burning fuel that is cut with alcohol will make less power, no and ifs or buts, period!

is that true regardless of the RON ?? I am curious to see if anyone has actually tested this out. A 100 RON fuel, even with 5% ethanol should still have a better output. But I would love to see some results. [/quote]

the quickest busa at the drags are all running 91 octane.The standard compression and ignition timing best suits this fuel for power.So in regards to power theirs calorific value(which i understand alcohol is lower),burn rate(to suit ignition timing) and resistance to detonation to suit compression.Having a slower burning higher octane fuel will just cook your exhaust system if ignition and compression aren,t optimised to suit.I had my bike on a dyno for a full day and didn,t even change the titanium pipes colour when on 91.Every time i,ve had premium(98) in it, the pipework has come back a different colour.Doesn,t pure alcohol need to run at 6:1 or something to run properly?Having said all that i,d run 95 or 98 on a trip loaded and lugging for the factor of safety.So id have to agree with the term being cut with alcohol.Alcohol has other benefits in intake cooling but i wonder if these benefits out weigh its lower energy content at 5 or 10%.?

The busa has fixed values for ignition advance (no knock detector), the ECM does not attempt to advance the ignition to get more power. Advance is set conservatively to run on standard ULP without experiencing pinging. Now you put a slower burning fuel like PULP or part alcohol which has less calorific value and the result is less cylinder pressure=less push on the piston. Pay more for less, go figure.

Hi there,
Do you see the oxygen molecule in your molecular diagram. The extra oxygen molecule which is found in the Hydrocarbon chain is what takes away the oomph. An oxidised molecular group has less calorific value than a non oxidised group.
In regards to fuel density, the old optimax, which had claims of having the highest fuel efficiency was also one of the more dense fuels that could be brought over the pump. which is why some turbo tuners like it. But beware if you ever had to cold start your bike, esp if it was carburettored, as it was a eal dog in the cold start department.
One issue with going above 10% ethanol is the risk to the poor schmuck putting it in the tank. Much higher and this and any fuel that is splashed onto your hand will burn, rather than just feel cold and evaporate away. Very bad publicity when people get chemical burns filling their car. The enviro way forward is diesel Smart cars on biodiesel, but not too many bogans are going to separate with the V8 Bommadore esp out my way. 
It's good to get this discussion out there though so that everybody becomes informed.

couldnt agree more with you more there graham, i worked for the last major biodeisel producer in aus until 2 weeks ago, they shut up shop cause feedstock prices made it unviable to to remain in buisness, until aus governments mandate a bio component it wont happen. major oil suppliers dont want it to happen cause it eats into their profit margins & they pretty much control the world economy.
So what yous are saying is putting in 98 octane in your
stock busa is a waste of time...?
An to stick with the normal unleaded if your bike is stock?

Premium gives less max power and costs more! Premium makes the motor run smoother, so some, myself included, prefer to use it on longer trips. The 08 model guys have no option but to use premium due to 12.5:1 compression.

Yep i reckn u are on the money ,we are just sheep,u step out of line they call u a lia,cheat ,fool or extremist then they will get rid of u somehow.. petro $$ reigns the world and causes 96% of the wars.
