Elf LMS is the control fuel Elf originally designed and made for Le Mans, it seems like a good brew. Makes good power, consistent, excellent quality and runs cooler which is all very logical stuff for turbo engines running in a 24 hour race.

Makes only a little less power than Turbomax, and is cheaper and not as nasty to use.

I still find it quite weird how this topic hasn't appeared long ago if its deffinetly a seat of the pants power increase. What happens in 10,000km when someone has to do a rebuild because it doesn't work out like everyone states.

This stuff has been in use as a performance increase for years.

You used to be able to buy toluene from the pump, as my boss used to run 20% in his Mini Cooper S all the time.

As for adverse engine effects, if you use 20% or under, you should be fine without engine modifications.

Hot 4s did an article on this (probably about 10 years ago now) and recommended no higher than 20% without doing other stuff to your car.

As it burns hotter than normal fuel, you can burn out valves if you use too much, and I believe they recommended stainless valves if you were going to use it.

2 questions...

1) What is the shelf life of toulene? ie) if I get 200L from shell or bp can I use 10L a week with every tank for 20 weeks - will the last 10L be just as good as the 1st 10L batch?

2) Do you have to shake it vigorously with petrol before hand to properly mix it? or can you just add it straight then add the petrol and will driving and cornering mix it up enough?

sorry for the questions - didn't do chem in school!

So will there be any differences in the ways we can add toluene (other than method B being more time consuming)???

Method A: Go to a petrol station with an empty tank, first add petrol or toluene and than add the other.

Method B: Mix them at your garage, shake well :rofl: and than add to your petrol tank.

Also will a 95 octane petrol increased to 98 octane by using toluene be the same or as good as a genuine 98 octane petrol (optimax, bp, mobile )???

Some mechanic mentioned that a 95-96 octane petrol increased to 98 by using octane boosters wont be as good as geniune 98 petrol when tuning the car :confused:

Incidently if you want to use it legally as fuel you need to approach the appropriate? Gov dep. and arrange to pay the fuel exise to them on any amounts you buy. I don't know as yet if this applies when you are using it in small amounts as an octane booster. EDIT: It is sold as a solvent and as such does not attract fuel tax thats's why it is relativly cheap. If you use it as a fuel then you are legally required to contact the appropriate gov dept and pay them the fuel tax due on the amount you use as fuel. The only question is .... is an octane booster counted as fuel.

Surely if you were using it as an Octane Booster for Track use it would be exempt from fuel excise? It certainly couldnt be illegal on the track, could it?

REV210: Did you change the C.A.S? How many degrees, if any?

Toluene Octane Booster sounds good. I was talking about it with a friend of a friend 2 days ago, who is a Petro-Chemical Technician or something and he said you would only need a Cup-full to make a difference, I realise this conflicts with all of your mixture levels mentioned here, maybe he has been sniffing it too much :P I am glad somebody re-dredged this thread from the ether :( 10-20% sounds like a good level.

Any one tried it with Synergy 8000. I am able to run more timing @ 16psi compared to when I run BP98. BP98 causes the car to go flat for a sec then pics up and then goes flat again. Running less timing fixes the power loss/dip feeling but that isn't the point :D

A similar thing happens to my car with BP98, I have tried Synergy a couple of times and the problem is not noticeable... Synergy is further away and more expensive - as you mentioned.

Cheers.

So no one knows???

If you wait a bit, the original thread starter + others who have contributed to this topic will see it and perhaps provide input to your query.

Patience O-B-1, people are probably on holidays, like me :) [but not online].

:P

I am guessing that Method A would be the go.

How do you explain to them [at the servo] why you want to put 50 Litres of BP Ultimate 98 into a Jerry can...? For your supercharged ride-on lawn mower? Lol...

I don't think they would knowingly let you *mix up molotov corcktails* in your backyard.

:Bang:

we ran a lexus v8 twin blown on c16 with great results, we ended up have 40 psi, 6:1 comp with 32 deg advanced with no det. used shit loads of fuel but sounded amazing. when we were turning this engine it didnt seem to perform untill we advanced the timing so far, something you might want to try next time Roy.

I'm also very interested in setting my car to use this fuel also, there was a article in some mag where they set up a gtr to run on c16, how ever i cant remember the results. From my memory c16 is made for forced induction engines. i would be extremly interested to hear your results if you go down this line. c16 does also have a slight lead content which will mean cleaning your 02 sensors.

If you own oil manufacturing facilities it's quite possible to buy any chemical and petrol you want in bulk :D

And how about quality of 98RON vs 95RON+toluene ?

    • Can also confirm these work a treat for most balljoints and bushes. If you have access to a big rattle gun, they make the job so much easier and quicker, compared to using a socket wrench or shifter on the c-clamp 👍
    • Its sort of street but got used for circuit sprints on account of I never drive it on the road because I dont have the time to spare. So it usage was sits around for months at a time then gets driven either 50 or 250 kms to the track followed by 20 laps followed by 50 or 250kms home followed by stuck in the shed until next time. So yeah neither fish nor fowl. Just dont want to break it on the track as a preference. Hence the fairly short sensor/mod list. Probably more worried about it pinging itself to destruction more so than anything oil related.
    • My thing I'd be doing, is pulling it out, and just getting the tune cleaned up for now. Before that even happens, checking over everything, like vac hoses, fuel hoses, etc. No point dropping thousands on sensors if the moment you start it back up all the oil leaks out, or it has massive vacuum leaks etc.   But really, to know what to do, depends on what your use case is. Hard core track car? Throw most sensors available at it. Street car, I'd probably just run oil pressure, oil temps, water pressure, water temp, probably fuel pressure too. I don't know exactly what the Link can handle and do with those though. And if it's mainly just to cruise the streets, rather than mountain runs, you can probably skip most of the above if you've already got them in as gauges and warning lights.   PS, inb4 "sell it and buy a modern sportscar"
    • Keen to see the turbosmart data, to date I've only seen negative things in terms of response for them. Very small sample size though.     Hawkins is a big advocate in his videos of the larger rear housings. I managed to make similar power with a lower spec motor on the smaller .8 rear, keeping decentish spool.  The people he works with now are big power cars compared to mine though, mine really is setup to drive around and enjoy.  I don't have any back pressure monitoring though, so couldn't say if its good or bad on my car, just that it does what I want it to do.   Future I want a higher compression more cubes motor to give a bit more bottom end and hopefully the new g35-1150 gets me to the 850 rear comfortably.  But maybe I won't due to exhaust back pressure.
    • No, I refuse to buy their cheap ass crap! I do need to order a bunch of different nuts/bolts to refill my nut/bolt wall though. Maybe you could go for a walk through Bunnings for me? (Or send me some stuff from your work? )   I really struggle to work out how the US standardised to Metric in what the 70s or 80s, and yet, half a century later, there's been little done to actually bring it into fruition. It truly baffles me    On the whole Fastenal thing, I went reading their site (My god they sell a lot of varied stuff!), and it seems like it really depends what store you're near if you can walk in and just grab a few small things, or if that branch is primarily distribution with only a small window of "counter time" available (if at all). That definitely makes it harder, as move locations and it drastically changes your ability for success   For things like your M6x1.0, if you want to work on your own Skyline, and you also have a "home workshop" I'd recommend setting yourself up a small Nut/Bolt wall/section. It doesn't even need to be big at all. Most things depending on the diameter, will be a specific pitch, like the M6x1, M5x0.7 etc. Bigger bolts is mostly 1.5, except for a small number of things and that will come down to torque. From memory bolts for the brake calipers (and other things that need a lot of torque) will end up being a 1.25mm pitch. Save up a few dollars, and order a range of nuts/bolts. If you want to minimise cost a little, buy something like M6 x 40, and M6x70mm (1mm pitch) in both. In addition, buy yourself an M6x1mm thread chaser. That way you have long bolts that you can cut down to size, and then chase the threads out. Funnily enough, I find what I'd pay here for ordering 5 bolts, I can pay about 50% more and you'll get 100 of them.   If that doesn't quite work out due to space / ability to buy plenty up front, then each time you need some bolts, order 100 of what ever you're getting. Put them in clearly marked containers. Over a few years, you'll acquire plenty of different sizes, and will end up ordering less and less. And the cost for 100 bolts won't be much more than you paid for your 5 you needed to order anyway  Just takes a little planning ahead, by investigating what nuts/bolts you'll need, and ordering them before doing the job.     Edit: If it's also primarily for working on just the Skyline, for some reason my brain is screaming that at some point, either Nissan, Nismo, (Or possibly a third party) was selling a "kit" of every nut and bolt in a Skyline, purely for people restoring/rebuilding. It'd likely be quite expensive, but would give you every/any nut/bolt you need for stock/factory things. I'm not sure if it's still available, or even if it actually fully came to market, it's just something niggling in the back of my brain that you could look into further if that sort of thing interested you? (It might have been for the R32 GTR or something specifically too, and not just any Skyline)
