Roy Posted May 20, 2011 Share Posted May 20, 2011 Curious to know what race fuels people have tried. Back in the dark ages when I had my R1 and when i first got my R32 it was common practice to try toluene, or the Shell 100 leaded fuel you could get from servos. But its been years since I have bene to EC or Wakefield and did that. When i first got to Melb i used to throw 10L of Sunoco in with 35L of 98 to give the engien some knock prevention when it was hot on the track. Looking around some websites this morning I am wondering if anyone can give some feedback on the following: Elf TurboEvo ... http://www.racefuels.com.au/fuelsDetail.asp?ID=20 Elf Performance (Perfo 105) ..., http://www.racefuels.com.au/fuelsDetail.asp?ID=31 Martini Super Turbo 1400 ... http://www.martiniracing.com.au/Super-Turbo-1400-Racing-Fuel.aspx Martini Grand Prix 700 ... http://martiniracing.com.au/Grand%20Prix%20700.aspx Looking at the Sunoco unleaded gear it doesnt seem to add up ... http://www.sunocoinc.com/site/Consumer/RaceFuels/UnleadedFuels/ but is a lot cheaper! Seems to be a tad better then the old Shell Racing 100RON So interested to know of people have tried any of the above as 100% tune or as 50% mixes with 98?

zebra Posted May 20, 2011 Share Posted May 20, 2011 From all accounts I've heard the ET 102 is pretty good, and cheaper than the ELF Turbomax or whatever they call it. Off the top of my head its rated in the US system so it would be 102 MON which would shit on the local 100 RON brews. Have you considered WMI as a knock preventative?

bigmikespec Posted May 21, 2011 Share Posted May 21, 2011 Anyone mix 98 with toluene or run close to pure toluene? Link to comment https://www.sau.com.au/forums/topic/365023-what-fuels-have-people-tried/#findComment-5824182 Share on other sites More sharing options...
Risking Posted May 21, 2011 Share Posted May 21, 2011 We used to use sunoco in the r32 GTR It worked well when the tune was right but we did melt a few pistons in hot temperatures. Once the tune was right it ran happily. We did run up an rb26 on an engine dyno running on a toluene blend. I don't know the ratio but it did not make much more power than 98.

Beer Baron Posted May 23, 2011 Share Posted May 23, 2011 yeah I say run the E85 bris. it will give you more power, and doesn't cost a bomb either. russ used to run the sunoco stuff but switched to E85. I've run with the Elf LMS (and turbomax) in robs GT3 and we used to use it in the alfa too. it was pretty good we certainly got a few more hp out of the alfa but it was so bloody expensive. talking over $5.50 a litre and that was 5 years ago and at the time we could get 'optimax extreme' which was the shell 100RON brew for like $1.50 so eventually we went back to that. I'm spewing as shell don't do the 100ron anymore and even united near me don't do united 100 any more either as I guess they sell E85 now. I'm going to move to that.

Marlin Posted May 23, 2011 Share Posted May 23, 2011 Even the super duper Elf, which in itself is in my experience superior to Martini and Sunoco, pales when any semblence of value for money enters the equation Troy..... E85 mate. E85. Link to comment https://www.sau.com.au/forums/topic/365023-what-fuels-have-people-tried/#findComment-5827526 Share on other sites More sharing options...

Beer Baron Posted May 23, 2011 Share Posted May 23, 2011 yeah I'm with marlin. I only even ran the stuff when I got scraps cheap/free when we were running the porsche GT3 cup car. and same goes in the alfa. I think these days the elf LMS is up around $8+ per litre. even when we got it for $5.50 rob's fuel bill for a weekends racing was astronomical. E85 is the only real viable solution. well actually there is one other. avgas. if you get your car log-booked you can get a fuel passport and can then buy avgas for your car. last time I bought it (they sell it at eastern creek from a tanker) it was $2.50 per litre (from memory). much more reasonable and good gain over 98RON.

Marlin Posted May 23, 2011 Share Posted May 23, 2011 (edited) When we ran the GTR at Tugga in 2008, we were bound to use Elf as thats what that car, and most of the period, were tuned on. We obviously relied on a 3rd party to fill us roadside, and I remember turning to Tim several times during that week and asking if he was enjoying himself, because that fuel top-up just cost us $500. We used over 600 litres for the event..... at $8.50 per litre. Seems like madness now, but back then, we all used to just accept it.

CameronBNR32 Posted May 23, 2011 Share Posted May 23, 2011 From what I understand the Shell Racing 100RON is just avgas with a government tax slapped on it... I have been trying to decide what fuel to run in my car aswell, kind of leaning towards running leaded avgas. Blue = 100/110 low lead (not unleaded, low lead) Green = 100/130 leaded Red/pink = Mogas / Shell Racing 100 Link to comment https://www.sau.com.au/forums/topic/365023-what-fuels-have-people-tried/#findComment-5827841 Share on other sites More sharing options...

Roy Posted May 23, 2011 Author Share Posted May 23, 2011 Main reason I was going to try Martini or Sunoco first was to get some good quality gerry cans that will seal up well and able to sit in the boot of the car in the garage. But will have to try and hunt down some from a client instead if the E85 is the way to go...actually.

Beer Baron Posted May 24, 2011 Share Posted May 24, 2011 yeah elf LMS smells wildly different to the other unleaded race fuels i've used and it is massively carcinogenic and it burns your skin too. lovely. avgas is not exactly good for you either and is leaded but cost vs benefit it's pretty good. the elf's big advantage is how highly oxygenated it is. can make great power with it. but yeah the price is out of this world. kind of smells like a fruity paint thinner.
