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 :)

    • Thanks for that, I'll check it all out. I can always do the brakes last anyway if its a problem.  The 16's are super cool, if they do fit I'll cruise around with them for a bit.  
    • Well, that's kinda the point. The calipers might interfere with the inside of the barrels 16" rims are only about 14" inside the barrels, which is ~350mm, and 334mm rotors only leave about 8mm outboard for the caliper before you get to 350, And.... that;s not gunna be enough. If the rims have a larger ID than that, you might sneak it in. I'd be putting a measuring stick inside the wheel and eyeballing the extra required for the caliper outboard of the rotor before committing to bolting it all on.
    • OK, so again it has been a bit of a break but it was around researching what had been done since I didn't have access to Neil's records and not everything is obvious without pulling stuff apart. Happily the guy who assembled the engine had kept reasonable records, so we now know the final spec is: Bottom end: Standard block and crank Ross 86.5mm forgies, 9:1 compression Spool forged rods Standard main bolts Oil pump Spool billet gears in standard housing Aeroflow extended and baffled sump Head Freshly rebuilt standard head with new 80lb valve springs Mild porting/port match Head oil feed restrictor VCT disabled Tighe 805C reground cams (255 duration, 8.93 lift)  Adjustable cam gears on inlet/exhaust Standard head bolts, gasket not confirmed but assumed MLS External 555cc Nismo injectors Z32 AFM Bosch 023 Intank fuel pump Garret 2871 (factory housings and manifold) Hypertune FFP plenum with standard throttle   Time to book in a trip to Unigroup
    • I forgot about my shiny new plates!
    • Well, apparently they do fit, however this wont be a problem if not because the car will be stationary while i do the suspension work. I was just going to use the 16's to roll the old girl around if I needed to. I just need to get the E90 back on the road first. Yes! I'm a believer! 🙌 So, I contacted them because the site kinda sucks and I was really confused about what I'd need. They put together a package for me and because I was spraying all the seat surfaces and not doing spot fixes I decided not to send them a headrest to colour match, I just used their colour on file (and it was spot on).  I got some heavy duty cleaner, 1L of colour, a small bottle of dye hardener and a small bottle of the dye top coat. I also got a spray gun as I needed a larger nozzle than the gun I had and it was only $40 extra. From memory the total was ~$450 ish. Its not cheap but the result is awesome. They did add repair bits and pieces to the quote originally and the cost came down significantly when I said I didn't need any repair products. I did it over a weekend. The only issues I had were my own; I forgot to mix the hardener into the dye two coats but I had enough dye for 2 more coats with the hardener. I also just used up all the dye because why not and i rushed the last coat which gave me some runs. Thankfully the runs are under the headrests. The gun pattern wasn't great, very round and would have been better if it was a line. It made it a little tricky to get consistent coverage and I think having done the extra coats probably helped conceal any coverage issues. I contacted them again a few months later so I could get our X5 done (who the f**k thought white leather was a good idea for a family car?!) and they said they had some training to do in Sydney and I could get a reduced rate on the leather fix in the X5 if I let them demo their product on our car. So I agreed. When I took Bec in the E39 to pick it up, I showed them the job I'd done in my car and they were all (students included) really impressed. Note that they said the runs I created could be fixed easily at the time with a brush or an air compressor gun. So, now with the two cars done I can absolutely recommend Colourlock.  I'll take pics of both interiors and create a new thread.
