Steve,

I'd say go and get a total tune geared for the toluene, and consistantly run the same mixture if thats the case. If you have an ecu with provision for two maps then it's much easier I guess. Otherwise if it's a PFC then go into the Settings and tune using the adjustment so the entire map for ingnition and then fuel. It's less accurate but easy to remember and change on the fly afterwards.

The best thing to do is to pre-mix the toluene in a larger sealed container (fuel can) with fuel before adding it to the tank. Investing in a good system to pump it into the tank is a good idea as well as the funnels tend to be messy.

Josh, the rule of thumb that I use is 5% for every 1 RON, so 96 ron to 98 would be 10% - this is slightly overestimating, but would see you right AFAIK

Keefy, Tolulene is a aromatic hydrocarbon. It has several uses, including a cleaning solvent, paint stripper, making explosives and fuel additive to raise its resistance to knock.

It is, afaik, used by some fuel manufacturers for exactly that purpose, and it works quite well. I beleive F1 used to use high percentages of tolulene in their cars many years back.

I have found its a handy additive if you intend giving your car an unusually hard thrash, or even driving in the country where there is no 98 ron available (long interstate trips) just to keep knock under control. If you retune your car (as Rev210 suggests) you will get even better results as you can increase timing - because of the greater resistance to knock.

It will be very handy should I run out of 98 ron due to these bloody bp shenanigans :(

Never heard of that one. Octane boosters will often contain tolulene to boost the octane. Remember and octane booster will raise the octane by 4 points, which would take 96 ron to 96.4 ron - doesnt really help if you are chasing 98 ron.

Tolulene is added to petrol by the manufacturers to boost its octane rating (resistance to knock) - it will clean your fuel system, but it wont foul it. I have never had a problem, most I have used is 4L with round 30L in the tank - so approx 13%.

Rev210, how much have you used before?

Octane boosters usually double up injector cleaners, for the better ones. Maybe if u buy the cheap ass ones it will for all u know, but if u were to buy the better ones, it's good.

AFAIK, there are different specifications for octane boosters.

http://www.nitrous.com.au/products.html << this is one such example, which i've heard from workshops is effective. But to what extent, i don't really know. Anyone know if it works?

I've used this stuff for years.

Toluene is not used in modern off the shelf octane boosters and is used far less these days in basic fuels. There is a push to reduce the aromatic content of fuels such that BP98 doesn't contain very much by way of it at all, pick up a brouchure and it says the % from memory only about 7%?. Why you ask? because it's pollution and bad smell all the way ;) oh and catylitic converters don't like it.

up to 35-40% aromatic content in your fuel is fine if you tune for it.

the F1 turbo cars ran 79psi of boost and made 1,000hp and the base fuel was pure toluene with n-heptane thrown in to actually reduce the octane number to comply with regs, developed for the Honda turbo's at the time (alan prosts favorite from memory) the term 'rocket fuel' was coined at this time.

    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
    • You haven't driven many modern cars then have you? Most of them have sfa steering feel with their stupid electric bullshit steering systems.
