Used 1ml/L in the tank today with 97RON (all you can get in Scotland). So should take it to about 99.3RON http://www.nitrous.com.au/ocharts.html extrapolated from this link. Not tried any other boosters.

I was half expecting a placebo only response after what a few had said, but certainly added to Shell Super makes a considerable difference to MY00 PPP decat with Dawes/bleed at 18-18.5 PSI.

Sounds smoother, pulls harder off boost and above 5000RPM. Midrange felt more ferocious than usual - my favourite second gear bump up hill incline in the wet usually has a bit of wheel spin but it spun for rather further/longer than usual.

Also a tiny bit more boost across the range - less than 0.5 PSI, and I now see peaks in my boost response again

I got it mainly for safety on track, but think I'll use it all the time.

I use it too John...
found the same...

great stuff...

wish my problem gets sorted soon so i can enjoy the car again

Which formulation do you guys use ?? Black/Blue/Yellow/Red ??
Cheers, Mark.

dingy

At the moment there is only black, some stockists still have red which is the same as your yellow.

Towards the end of march this will be standardised as Black and yellow

Please correct me if I am wrong.

The RON of a particular fuel is simply the ability of the fuel to be less suseptible to pre detonation(knocking). I.E the higher the RON number the slower the fuel burn.

Is it that your car is adjusting the timing and fuel map to get a benifit from the higher octane? Is the ECU learning the new fuel mixture??

I'm a bit confused?

The Scooby & Evo guys use Tuoline, basically a thinners, to raise the octane on the Drag Strip days

dingy

Toluene is very good but also illegal on a the roads and is very harmful, very cancerous.

But if you mix this 12% with SUL it gives you 107+ Ron which is good.

But 12% of a tank of gas is a lot, and a full bottle of NF is just under the RON rating.

chuckster

That test Dingy quotes states that you need 250ml of NF to treat 80l of fuel to a 2.8ron rise, which is odd as I thought you only needed something like 1ml per litre for a decent result? Sounds expensive

' 250 ml treats 80 litres RRP: $29.95

Time for an Aussie-made product. From Perth, the NF Octane Booster Racing Formula was the smallest bottle in the field, but looking at the mixing ratio, also the strongest NF relies on an incredibly small dose – a mere 3 percent! Claiming to increase octane as much as 6.0 RON, NF took the gold medal in a surprising tie. If it were a split decision based on concentration though, it would be the clear winner.'
How big is a bottle of NF? Is the mix ratio really that great? 150ml per 50L (fill up)?

Or looking at John Banks quoted example...
For 98RON rated fuel 1ml/litre gives a 2ron increase, 5ml/litre gives a 3.5ron increase - great! However for 100RON rated fuel 1ml/litre only gives 0.6ron increase and 5ml/litre gives 2.5ron. Strangely inconsistant? (As a comparison Dingy;s source shows for 96.8 RON 3.5ml/litre gives a 2.8ron increase)
It;s all very confusing, though I want to try some so where can I buy it?

dingy

Chuckster that was an older mix BTW and not the same stuff as we have now.

But its just an example.

This is the results for the uk Market

95 @ 1ml 97.8
97 @ 1ml 99.0
98 @ 1ml 100

So if otimax is 98.8 if will be greater they are set at exact 95, 97 and 98 RON levels.

All the contact details for stockists on on the website under stockist

Toluene was used in the F1 engines in the early days of the turbo era. It had some good properties in terms of octane rating, but the cars had to be used with a fuel of 102 octane so some lower grade stuff had to be added. It had one main advantage - it contained more energy per litre than normal fuel (in the same way that diesel does in comparison to petrol). As ever, it came with a few downsides;

• it's bloody difficult to get to burn properly - hence the development of flame accelerators that have found there way into modern fuels.
• it's carcinogenic
• it rots copper based metals and some plastics, such as fuel lines and "O" rings

Stick to the tested and approved stuff for the road!

I dont use the Tuoline in my car, however I was trying to figure out how the engines perform better with a higher octane fuel if nothing else is changed.

Is it that the computer compensates and adjusts the timing and fuel map for better performance?

john banks

I think it is the timing, and the fuel probably burns more efficiently/evenly, but there is a lot of techno-waffle talked about them. Craig mentioned 7.5 degrees of extra ignition advance was possible on a 22b IIRC. This would liberate extra power

I probably see more effect on my car as the higher octane and extra advance should cool things as I am pushing the boost a teeny weeny bit for a small turbo.

BugEyed

The effects depend on the car - as usual.

With a recent Scooby the effect is that the extra octane allows the car to advance the ignition settings towards the maximum that are preprogrammed. In effect, it doesn't retard the ignition because of knock. However, putting in higher octane indefinately doesn't result in more advance, it just reaches the limit. For a standard MY01 this limit is 95 octane, for a PPP MY01 this is 97 octane. However, modify the engine (decat the exhaust, improved inlet, ported headers, improved inlet hoses, more major mods) and the limit may be higher.

So, the rule is, the more mods, the higher the octane required. If you get a map made for your car (ie. Unichip, Link etc.) stick with the octane used to map it. If not, you will reach a limit of octane above which you will get no performance gain for an increase in octane (and hence cost in fuel boost).

scoobyscene are one of the UK distributors and on their web site the directions for use are totally different as you can see below.


: To use NF Octane Booster, simply add 5mls per litre prior to re-fuelling. On average, 1 bottle treats up to 6 full tanks of fuel.




I've just bought an S/TB Japenese import that has a 100 ron WRX engine, so I want to start using it, but it would be nice to know the exact quantity to use per litre.

dingy

There is a few methods to use NF, they are work in a simular way.

john banks

It looks like 1ml/litre is normal for road use - this treats 300 litres on one bottle. 5ml gives you diminishing returns (ie less octane/£) but may be useful on the track? If you need 100RON from SUL then 1-2ml/litre is surely the range to use?

Crusty

Label reccomends using a bottle of yellow formula before using the black version, any comments on this ? injector cleaning perhaps..

john banks

My car only has 15000 miles and had a fuel additive at the service recenly so I wasn't bothered. It is definitely smoother and a fair bit friskier than usual at the moment

Cheepest place to get it in the uk?
