Octane boosters.

[KiwiRS4T]

The only research on octane boosters that i have seen shows that they do stuff all. If you really want to change the octane rating of pump fuel you will have to add 10% or more of something like toluene or ethanol.

Hmmm... it looks like you missed these articles then:

20% Toluene +2.5RON

500ml Nulon Octane booster (60l tank) +2.8RON

Octane booster in action

Quote: "Both the Nulon Pro Strength and the NF Racing Formula rated the best octane boosters in our test... ...Still, both proved extremely effective at increasing octane, even outranking Toluene, which needs much higher levels of concentration."

Why bother running around trying to source and use large amounts of toluene when you can buy a bottle of superior Nulon octane booster anywhere for $25?

The guys doing these tests know WTF they are talking about... more than can be said for some on these forums!

All respect SK but don't the Japanese factory ECU's in the RBs have fuel maps for the 100RON fuel used over there?

In an "untuned" RB (factory ECU) I thought that running a decent octane booster with 98RON local fuel would have benefits

i.e. running the octane that the ECU is mapped for... even more so to avoid detonation with increased boost levels + hot weather?

Clearly it's a different story if your aftermarket or factory ECU is remapped for 98RON

I was about to go out and buy some but not so sure now

lol you do realise he said that on 21 Jan 2005, 07:18 AM ?

Yes you're right. I did my research years ago and all the products produced only a fraction of a RON number so I have never bothered. I don't remember seeing Nulon mentioned at the time.

Well I do neither. I am using a petrol from Gull called Force 10 and it is a 98 petrol with 10% ethanol added. It enables me to run more advance and more boost. I have always used it on my car so I cant provide before and after figures. If I were in Aus I would use E85. There is a comprehensive thread on that in the Skyline section by Guilt Toy.

I guess if you lived in an area where you could get only low octane petrol Nulon would be a solution.

Only if you lived in the western suburbs of Melbourne.

Haven't sen it available anywhere else.
