Sniffy,

Yeah, just keep a bottle handy for the occasions when you can't get to a decent servo.

51Jay,

Thanks for the details on the location and price, what is your suggested mixing ratio, I've heard between 15-30%.

Giz01,

Couldn't they find a decent car to perform the test on?? Just kidding. I think it is sensible when racing to add it just for added protection.

Ait,

Your the one who has been running your car on 98+booster, notice any difference? Just means that we don't advance out timing as much as we would with 100RON fuels.

Everyone,

I don't like to get covered in any chemicals, whether cancer causing or not, just be sensible and don't sniff or drink it.

See'ya

If the octane rating of Toluene is really 122 then adding

10% gives 100.4

15% gives 101.6

30% gives 105.2

I've decided to keep the tuning for BP 98 octane and add 10%

when racing on full boost as a hedge against detonation

51Jay,

Don't want to burst the buble but at 20% mix the RON improvement is +2.5 and 30% is the maximum recommended, therefore +3.7RON is the best your likely to get. This is taken from an article in a magazine and tested on a knock engine. This is still more than enough to protect you from detonation, therefore it is still worth doing.

Doesn't work like that I'm afraid, life would be so much easier if it did. The fact is you can't work it out. The only way to determine the RON(research octane number) is through the help of a $200,000 knock engine, which all oil companies use for testing of there fuel's RON.

Don't believe all of the bottles claims about there octane boosting ability either, the set there own scales which don't reflect well to real life. If you want guaranteed high octane then use an unleaded race fuel such as Elf or VP Motorsport Fuel 103, about 107RON, the highest you'll ever need to run in any normal car. With the higher octane you can advance timing and get more power also.

51jay,

Toluene is good stuff, if you don't mid premixing it, just remember not to drink the stuff, some of the other guys use it as mouth wash. Go figure!:bahaha:

thats cause we are tough, and have cast iron guts from drinking to much coke

Premium unleaded's like the BP Ultimate, Optimax etc. are supposed to provide better fuel economy due the increased fluid density. I don't know why an octane booster would improve the fuel economy, but if it does that's great. Not likely to offset the cost though at $20 per 60L.

How do you work it out ??   I'm using 98 octane for the BP Ultimate and 122 for the Toluene which are the figures they claim and just multiplying and dividing the appropiate numbers

Roughly,

The BP ultimate 98 stuff would be a closer guestimate due to it having the lowest % content of aromatics.

The mixture of 30% toluene to 70% BP98 will yeild an approximate RON of 105.

Well the tune up + Toluene must have done something. Just back from Willowbank. My previous best 14.8 dropped it to 14.3 good enough to cream 3 x commydoors including a HSV Club Sport 5.0LV8.......Skylines 3...commydoors 0 :)

14.3 @95, 14.6 @ 99.7 ?? 14.8 @ 91

Was very hot, Track temp 42' Iwas leaving after 4 runs at 6.15 pm when a few other Skylines were just arriving. In retrospect I should have stayed on and run acouple more when everything had cooled down a bit.

MRE Still behind you in the mph, just couldn't make the 100.

I'm really looking forward to Wed night though, should be pay off night

GTS-T V Spec :) and especially Club Sports that do huuuuuge burnouts :)

    • Hi from Canada, Both of my calipers are starting to fail. My car is a 2005 M35 Stagea ARX and I can't seem to find any parts or any cross reference caliper that would fit my car. Is there a company or a similar caliper that would fit and I could replace the OEM one. Or if anyone knows where I can find a new OEM. Any help is very appreciated. Let me know!
    • Maf is a question mark but TPS  I have set at 0.47, the fact that I’m getting proper voltage range out of it with the key on leads me to believe it’s functioning properly. I’m getting proper voltages on basically everything. I still need to look up voltage ranges for z32 maf and test that 
    • Honestly no not at all, but it’s a very basic tune, it’s stock injectors q45 tps and z32 maf. Other than that it’s a completely stock base map. The file is from nistune and from my understanding if it was tune related I would be able to unplug maf and tps and it would still start even if it was a really shitty start. I have tried starting it with coolant temp, maf, and tps unplugged none of those 3 togethor or individually changes anything

    • What does it look like with highway driving? And yes, I had a similar thought as Duncan. It looks quite similar in my Stagea and I have made myself accept it as normal. Might have to look into it some day   Highway gets as low as 10l/100km on my end so I'm not as worried about it being a mechanical issue. More likely just the tune on the haltech.
