Ive been using toluene for a while now, I took the safe option and gor the Material Safety Data Sheet (MSDS) when I baught it. I have used it with bp ultimate 20l Toluene 40l bp, this means u can be more aggrecive with the timing and so forth. Now I run it with avgas. Same deal 20l toluene with 40l avgas. Cant believ the differance, B4 I was making 268RWKW with bp and toluene now with the Avi and toluene 316RWKW. Big differance the tuning is vital to to this though

Yes, all fuels do that hence some people like to 'sniff' them to get the central nervous system effect. If fact ALL  

solvent based glues and paints have the same classification.This includes ordinary correction fluid like "liquid paper".

ethonal isnt, and neither is liquid paper

ok lets pick nits then. :)

if I was reffering to alcohols like ethanol as a 'solvent' then I'd be wrong wouldn't I. Just like saying water is a solvent.

I should have said petrolium based solvent or something.

I believe the 'new' version of liquid paper doesn't contain xylene anymore (it used to), same as the old artline markers.

One thing i would like to know is, does anyone running toluene with Premium or Avgas run an exhaust temp gauge?

On paper the mix does increase exhaust temps... just wondering if they were measurable and whether they bumped temps up to around/over 1000degC.

MattR... didnt you lose an engine by dropping an exhaust valve... could the increased exhaust temps from the fuel mix your running be a contributing factor???

That is a very interesting point Roy.. If the increased exhaust temps from the fuel mix possibly damaging the exhaust valve.

As said before by a couple who use it on track bikes etc.. No problems as long as you don't use more than 30%.

20L of Toluene is just over that 30%.

Remember heat is a factor for killing ceramic turbo's hence why they don't like track days.

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 :)

I've repeated the experiment over and over again as BP98 is slightly cheaper by around 3cents per litre.

It would take a big effort to get your exhaust temps up around 1000degC your Turbo ex.manifold and dump pipe would be white hot.

You can only buy Toluene as 100%. It is labled Methyl Benzine 100% V/V Toluene.

I think 4 Doorz supplier was looking for an excuse to stop selling to him at $42/20l as the price elsewhere is now over $50

obviously expensive motoring....has anyone got a hard price on 200L drum 'cause that would be the way to go

Ive been in two cars with EGT gauges, one got a little over 900deg C, the other sits in the mid 800s. Both were on pump gas running 1 bar (give or take).

I dont think it takes a big effort, just 2-3 laps of your local circuit, which is when i use toluene.

PS - Im so glad i dont have an oil/water temp gauges or an EGT gauge, what i dont know cant hurt me.

Rev 210, a little interested as to how you are calculating your RON levels...?

It's a bit of a very rough guesstimation, since the real calculation of RON is done on a knock engine.

My idea (probably wrong) is that the chemicals present do not adversly effect each others RON/MON by reaction. That way we can work out the rough average RON of the mixture.

I guess the bottom line is that the Toluene or Xylene mixture is definately better than the ocatne boosters commonly found on the auto store shelf.

Seems that way, as now he is saying all purchasers need to have a CAMS license, and all BP servos have told me that I have to take my CAMS license to the BP depot (the ones who have heard of toluene that is).

I agree 200L drum would be the way to go...anyone got prices? where to buy?

I wouldn't go to a hardware, try Shell service station or depot and talk about it as solvent not fuel, or Trade supplies of Automotive paints.

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. (is fuel tax included in price of retail octane boosters?)

Cams licence I believe only applies to leaded fuels

    • What 1.5 way? There's no such thing really as a 1.5 way, just different ways of explaining 2 ways with different ramp rates. HOWEVER. In any driving in a straight line your 1.5 or 2 or 1.7 way should have no clunking at all. With the clutch fully depressed the diff should be silent (unless it's welded but I'm assuming it's not). Something aint right here.
    • Clutch is a spec brand, new clutch system,( PP, flywheel, friction disc, etc. pull type) installed 100 miles ago, with no problems.
    • looking for some help and maybe some insight on others experience with a new LSD. R34 GT ran and drove beautifully, but always alot of grip loss due to the open R200 rear end, so I just installed a new 1.5 LSD way into the stock open R200 for a ER34. Simple. Everything seemed right. I test drove for the first time this weekend. as I started to back out the garage the first time slowly with tires straight it sounded and felt like I had a loose or half disconnected drive shaft...that was clucking around loose and shaking entire vehicle, and making it feel like the trans clutch was spontaneously slipping then grabbing very roughly while just letting out pedal slowly. I backed it out went to pull forward with the same noise, shake and slip grab feeling with hesitation, I turned the tires to back out more and then pulled ahead some same thing but worst because of added wheel resistance (which that I expected) puzzled … pulling it back in checking everything over and finding nothing wrong, I tried it the next day. same thing, couldn’t believe how it shook everything again making a terrible noise and making it feel like the trans clutch was slipping and grabbing, but I got it out of garage into the driveway, got it straight, drove forward and then reveres a few times in a straight line everything shaking , causing what felt like clutch slip and grab every time, sounded like right behind front driver tire and I could feel it in the floor board with my feet,... worst right when beginning to let clutch pedal out to engage slightly, shuttering and sounding terrible along the way…I managed to slowly get down the road, babying it the whole way, once I was rolling (out of 1st) seemed to be better and between shifts, then clutch felt closer to normal…not slip/ grab etc., but back down to any stop, straight road or turning, same thing. Made no difference if all tires were straight or if I was turning. All other gauge read out correct. with in 2 miles as planned I reached the empty parking lot and performed the break in procedure that came with lsd, essentially to drive in a figure 8 a bunch.  Did this, binding chattering, and shaking the car the whole way. I drove it back home seemed somewhat normal once I was in straight line and past 10 mph or so, and I know it will “bind” on corners and cause some tires squeal when turning especially from a stop, but when I begin to move it still causes what feels like the trans clutch to slip and jerk badly as well as shaking the entire car, and sounds terrible, that I didn’t expect. I used the fluid they supplied with LSD kit and did the breaking, planning to change fluid as they suggest after breaking, but wondering will it get smoother or less aggressive with use? maybe a 1.5 is just too aggressive for normal road driving?   I have a LSD that I put in my 71 cuda when I restored it, with amazing smooth , quite yet effective results. Different style LSD but that ones a joy to drive. maybe expecting too much from this R200?
