Octane booster - any good?

[k20 gtr]

Is it worth putting octane booster in the R, I have some NOS branded stuff that boosts octane by 3 points.
Its just a one off for a track day. Will it do any harm, worth it etc??

My car is running 1.2 bar, std turbo, avcr, hks boost contoller, front mount, 3 inch system and blitz air filter.

millers is the best octain booster.........it's only toulene/xylene and methanol any way

The question is probably do you need the octane booster? Are you getting DET, do you run more timing advance?

As Danny says, there's not much to them really; mainly simple benzeneoids (that'd be your toluene [methyl benzene] and/or xylene [di-methyl benzene]).

 

[vss irvine]

its not going to do any harm, we used to run it all the time at trackdays

just wondering mate, why are you using an avcr and an hks boost controller?

well spotted.

 

[williams]

im guessing he means a safc? just curious though.

:doh: yEAH SAFC, I allways get those two mixed up. I have no need for it as such, just wanted to chuck the bottle in to maybe get a bit of extra power on the day, but dont know if it would do any difference if its not mapped to run the higher octane??

It will protect the engine rather than give it more power, for that you would have to remap. But I would not trust that beacuse if you got your mix wrong after ....bye bye pistons..
You could go for 100 octain Shell fuel...its only about £16 a gallon...yes you did read that correctly..

A Shell garage full stop would be useful in Perth, they shut the only Shell here last year! Having to run poxy Tesco 99 these days....

 

[k20 gtr]

Do forecourts sell the 100 octane? not that I would buy it at that price. V power is 99octane, makes it look a bargain.
No shell in perth, I will need to fuel up in balbeggie then john, I'm sure I will need a trip down to dunfermline for a refuel though, can see it lasting the day on one tank...

 

[PobodY]

I've said it before; chances are that the 99RON fuel at Tesco has come from Shell in the first place. It's not exactly the same as V-Power, but that doesn't make a huge amount of difference on an "everyday" basis.

If it's not so hard to get hold of the ingredients, you can probably make your own octane booster and just add that with every tank of regular unleaded. - I might investigate that.

Ok, octane booster does give more power and does reduce det. I am a Millers dealer and this, along with their other products are very good. They do a +2 octane that i use on the road and a +4 octane that i use when on track. I can bring some to the sprint day if anyone wants some.

NOS branded octane booster is a joke. 3 points is 0.3 ron. Don't be fooled it makes 99ron 99.3 so a waste of money.

Millers do CVL turbo, that actually does make a difference.

BTW if your running 1.2 bar on a 3 inch system with FMIC, there is quite a good chance that you don't have the fuel system to support that for a track...

 

[skiddusmarkus]

I have a full box of the older Millers if you need any.I don't use it now as car is mapped on tescos 99ron.

 

[bracpan]

Dont forget adding any booster is illegal for speed events...
Shell V-Power can also varie from 97 to 99 oct.
You can only buy 100 form a specialist Shell supplyer and that is legal to use plus ist granteed 100ct as well.

Is this because he doesnt have an uprated fuel pump, injectors etc?

 

[Fusion Ed]

Yes. I dont see many pulsars that can run 1.2 without showing slight lean spots at max power/torque.

 

[Spikey]

Did BP not offer high performance fuel was it not 103 Ron or similar? But in test it showed less gains that tesco and V-poweer

Octane number alone tells you nothing; that's just resistance to knock. However, if you've got more resistance to knock you can run higher boost/compression/ignition advance and get more power from the engine. - That's why it's so important on forced induction cars.

If you compare performance fuels in something like a Mondeo you'll see no benefit because it's not generating any det on standard fuel so gets nothing from increased octane.

Similarly something like ethanol gives you a higher RON value, but it has a lower calorific value so you need to burn more of it (~30% IIRC) to achieve the same power (and by that I really mean the energy from it).
