Tuned on V Power Racing

[Oztrack Tuning]

I filled up with V Power Racing today and the initial indications are looking favorable. It will likely be fine with about 1 -1.5 degreea more timing but i havent tried it yet.

It leaned it out in most of the cells in my VE table by about 1.5% and my car is tuned in open loop. Thats only about 0.2 AFR .

It also seems a little less prone to knock retard as expected and thats with a high performance timing table. My engine has 10.7:1 comp.

Certainly even if it doesnt gain any power it looks 100% fine to put in any car without a tune change...and will likely be a safer fuel to race with. :teach:

Good stuff Oztrack I might have to give this petrol a turn, I have always used BP Ultimate and sometimes Vortex 98 when I have to. It's properly about time I try something new.

Cheers Oztrack. Always good to hear about which fuels are good and safe to put in our cars!

Where is that thanks button when you need it!:thumbsup:

[chilly]

i dont have much choice on premiun petrol here in Nowra
caltex or V power

i started putting V power in a month ago and have found it to be just as good as any other premium i have tried
i run 11 to 1 compression but dont have the expertise like Steve so cant give detailed report...just my aged guesstimation
:wave:

Steve , Interesting results there ! I have also experienced the few % leaner on the V- power ( no V-Power racing here ) in the stroker , But find at high load above 4500 WOT it knocks . I run a bit more Cr then the 11 you are running so that would contribute ! But must say at lower loadings it is very impressive ! Normal fuel for me is Ultimate , seem to be getting very irregular batches up here though !

[VYR8HSV]

Does anyone know if this fuel will becoming avail
over here in the west???
We have only BP Ultimate or Vortex 98..

Be nice to have a different brand thru the price cycle.
As BP always seem to put there prices up 1st.

Sounds good, might have to whack some in, fire up the wideband and see how it goes. Another degree or so sounds nice. What fuel do you usually use now?

The V-Power Racing is good fuel but I think it would be wise to wait until you have run 2 tanks through your car before you make any definitive comparisons. As Swingtan in another post noted the ethanol content will absorb any water in your tank. When the servos do their conversions to any ethanol based fuel they pump em right out fill em up then pump that first load out again before selling it. After 2 tank fulls my car starts to go better and the engine notes changes to a more aggressive note.

Hmm.... needed a "thanks" button for this one.

It's great to see some hard figures coming out to confirm my "seat-of-the-pants-o-meter" testing. For those that can really play with their tune and want to speed up the "run in" period, try adding around 500ml of metho ( possibly more ) to a tank of non ethanol fuel. V-Power racing is 5% Ethanol, or 50ml of ethanol to every liter of ULP. So in the average 60Lt fill up, you'd have around 3Lt of ethanol. Running a batch of metho and possibly a fuel system cleaner additive would be a good preparation step before really testing out V-Power Racing.

One thing I found when I was running water and metho injection, is the car did not like E10 98 (think it was boost98) ethanol at the same time, didnt get any logs but it wasnt nice. Just running straight water now but havent tried it again.

Interesting...... Last Christmas I ran some cleaner through my tank which was a 50% mix of metho and Nulon injector cleaner. I had a tank of V-Power racing and I was going on holidays to Eden, towing a fairly big trailer. The car ran like a dream, no issues and good mileage. How old was your water / metho mix? any chance the metho had evaporated out ( though that would have made it plain water and that's running ok.... ) I guess it may have been a dodgy batch of fuel?

I don't think there is any problems mixing Ethanol and Methanol, unless maybe you mixed a bit too much metho in, as in 100% metho :lol:

Just don't forget the Orange Juice ..... :yahoo:

I used to run 50/50 water/metho (ethanol). Gave a nice mix of anti-detonation properties and the cooling of the water. Musta been some bad fuel. You could smell the metho in the mix and it would still burn a little. I havent tried 100% metho, dont like the idea of an ethanol fire steming from your windscreen washer bottle :shock: bad enough as it was. Great for cleaning the windows though :lol:

Jez

[swingtan]

NO! Don't run 100% metho, I was only joking.......

I think 100% metho will cause all sorts of issues with the tune. You'd be adding in a huge jet of fuel that the computer wouldn't know anything about. The whole idea of the water injection was to help control detonation by cooling the intake charge in the combustion chamber. The addition of metho was then used to help offset the "quenching" effect that the water had on the ignition of the fuel mixture, so adding too much metho would tune the mixture into a really bad fuel and would probably upset the AFRs. I'm pretty sure you know all this though....

[JezzaB]

:lol: you thought I was gonna do it didnt you!

Some of our crazy american friends run 100% pure methanol or ethanol and a few other crazy things, but not me. Methanol and ethanol are still fuels and have very high octane ratings.

Injecting 100% water makes your AFR's fat as the water displaces some of the air in the cylinders.

[swingtan]

too right.... We used to only go as far as a 50/50 mix in my brothers 12lb turboed 186 motor. It was a screamer.....

[Oztrack Tuning]

I drove the car until it had minimum fuel and then put in 45 litres.

Its the 100 Octane V Power Racing which isnt available many places but this servo is 11min drive from WSID if anyone else is interested.

My engine comp is about 10.7:1.

[Alex(AUS)]

I have tried it in my Supercharged Camry and it dropped the AFRs by 0.7 points (quite a lot when you think about it). Not good if it is tuned on the edge say 12.5-8 (which it wasn’t). From the sounds of it, the effects on the N/A LS1 aren’t as pronounced.

It does idle/run noticeably smoother and I would say it allows for more timing also. I am not sure if the standard tune/map and learning parameters would take this into account particularly with the torque tags present.

I haven’t tried it in the Senator yet ... will give it a go next fill up.
