Just a question if anyone has used this fuel, up here in QLD you can go and get what they call 100 racing from the pump. I'm guessing its ULP but after bad results with Shell 98 I'm reluctant to give it a go. Has anyone any history?

Has 5% ethanol in it so be my guest.

i think he is saying thats a bad thing ?
-
What pump? I've never seen one, but then again I don't get my fuel at shell. Whats it worth a litre?
-
Anyone know where to get afforable 110 octane race juice in Brissie?? ::)
-
Moss Street would be a likely place to start -Auto Barn
also heard of people buying thru Super Cheap Auto ????
If you Know anyone with a light plane ....they have access to the good stuff ;)
-
Soooo Lozza I take it thats a no?

Never had good experiences with ethanol, but don't take my word as gospel :o I brew 110 it's as easy as.
-
So, what IS the best pump fuel? I've used BP Ultimate and found it good, but then I was recommended Vortex 98. I've used that too and to be honest on the 2-strokes I can't tell any difference. Both appear to burn fine with no strange deposits, and no pinging or whatever.

My wippersnipper never ran so good as it did on Lozza's home brew,

I've run ethanol blend fuel in my trusty Rodeo ute and found no noticable difference in power but lost about 1km/L, I used three tank fulls and got the same each time. Haven't tried it in any of my bikes.
I've tried my TT500's on regular unleaded and they ratlle and clunk a fair bit. No problems on premium unleaded and I haven't yet noticed any difference between brands.
Lozza, what's the go with your secret brew?????????????????????????????????????

Can't comment on the Shell 100 211kawasaki or even the 98 but understand completely your prob with Qld fuel suppliers. I have had serious probs with BP's Ulitimate with it being ultimate shit! or atleast it was from my local supplier in Yeppoon, I'm not sure if there is such a thing as a reliable fuel supply as in getting what you pay for from a Servo so thats why I have gone to AvGas. I don't think there going to screw around with that fuel supply and the Octane rating of it, not unless they want planes crashing that is. ;D
-
Maybe tuning the CR to whippersnipper specs then Noel ;D I have found BP 98 the most consistent out of all th 98's.
Secret Brew will remain just that ;)

can i detect the sweet aroma of nitromethane ????

never had problems with ultimate over here. are you guys who are having trouble with it and other high ocatane fuels aware that you have to retune your carbs/change plugs to suit those fuels? each time you change to different fuels you need to re tune your bike to suit the fuel your using
-

hmm... if it's not ethanol or methanol, MMT I assume, rather than the even more evil TEL?
-
I used to add about 400-500ml of "Methyl Benzene" to 10 litres of good fuel and you could feel the difference.It was widely used at Dirt Track events I attended in the 70-80's.I only ever ran it in 2 strokes.I would get it from a local fuel wholesaler.BP from memory. It would require a log-book at least these days I imagine to obtain-if at all.
-
we used to use tolulene in a race rally car, that might be still available over the counter
-
Tolulene/methyl benzine at best will give you 1 or maybe 2 octane points, and SFA detonation resistance.100mls of acetone per 10 litres will do as good a job.
You want some serious HP you need Elf Moto 124.FULL STOP.
-
then there is always the old way of doing it.
Turn the throttle more and back it off later into the corners. that will always do more than any fuel you will buy/make. :)
i just use standard pump unleaded and find that fine, i always use Mobil though !
-
Hey Hoony it might make the beast start easier ,just harder to hang on too.
-
Hi Guys,
I think Hoony hit the nail on the head. This is vintage motocross not Grand Prix Road Racing or F1 Karting. The engines in the majority old bikes run just fine on standard unleaded. Sure there are some that have always had problems but playing mad scientists with known carcinogens shouldn't be encouraged.
Sometimes a little knowledge is a dangerous thing and if you think playing with Toludene/methyl benzine is good practice then I hope you are taking suitable precautions [if not you could be in serious trouble down the track].
If the optimum fuel really means that much to you then call Tony Hatton and get some ELF Moto 124 as Lozza suggested. Its designed specificly for bikes and is about the best legal fuel you can get, it is absolutely consistent and mixes with oil superbly.
Most good tuners favour using a consistent fuel instead of chasing your tail looking for a univeral panacea. If this is what you want get some ELF and live happily ever after. It is also much, much safer than trying to make your own.
I'm not trying to poop your party, but please be careful.

However racing is racing, most racers given the opportunity will go for the race win and/or go to great lengths improve their machinery.Considering the stupid money people pay for some of Don and Gary's period crap, using decent fuel and tuning for it, is a very cost effective way of lifting throttle response and the engines output.Shaking a can and pouring it into the tank is pretty simple, requires no tools or skill.
Hoony I can gaurantee that with a engine in a resonable state of tune, that after using 110 ,no way would you go back to 91 ULP.
-
I agree Lozza, I wont be going back to using Servo pump fuel after using Av-Gas. My choice to use Av-Gas had very little to do with performance, although the engine does perform better with it, but had more to do with engine preservation. No detonation, runs noticeably smoother, cleaner burn and I'm sure there are a lot of other technical sounding reasons why its better to use but the bottom line is I LIKE IT ;D
-
Hey Lozza i dont know about Hoony but i have had the big honda go past me a couple o times and he doesnt need any more grunt, 4th gear starts at Barrabool . Faaarrrrkk .
-
Still stand by what I said. ;)
-
You need the log book for all leaded fuel, or know someone who has the log book
-
yeh and re mortgage your house too, that elf stuff is liquid Gold I nearly crapped myself when i saw the rediculous prices.. :o
-
Well i changed my fuel and tryed BP ultimate still the same oil castrol 2T , on the weekend in my YZ400E and it did make a difference ,no pinging and very smooth power . I had gone away from it after a batch went off after being left in the tanks for a while and running 6 bikes on it i dont like throwing left over fuel away , The only trouble i noticed was Emma's CR80 was hard to start although i had just rebuilt and jetted her carby ,Once goin it was very fast ,maybe to fast for my little girl so not sure why it was yet.So i imagine goin up another 10 actane would make as big a difference again .
