Hi Sam
Yes, I don't know what the boys are doing, but 747 dosen't appear on the "supercheap" website any more, so perhaps old stock . . . . or perhaps Scotty just wanted me to do the work.
Anyway, I found a company in Adelaide with 16 bottles on the shelf, so Scotty dusted off his credit card and they are on the way.
Oh and the Eski has arrived and signed for. Good service from DHL once more!!
I'm getting excited now, only just over a week till I see you and the boys again!! Greeeeeeeeaaaaaaaaaaaaaaaat In exactly a week from now I'll be in the land of upside down
Shorts or Jeans. Hawaian shirt or ski-jacket! Chinas or Wellys?????? Sunglasses or scarf. Will that "jetski carb-testing" wetsuit come in handy
So . . . . . . . . Avgas and 747 it is
Best Regards

I don't care how cold it gets in England, if you think Hawaian shirts and shorts are the order for Phillip Island in late May....your dreaming.
As the late great Barry Sheene once said while commentating from pit lane....."Welcome to Phillip Island, gateway to hyperthermia"
Tell me if this video makes Phillip Island look like a warm place in Winter.

Nice driving from the colourful Italian there.
So it's wellys, wetsuit, thermals, ski jacket, woolly hat and gloves then!!
Did you see Sam nearly loose it at the end with a rapid rear tyre deflation. That could have been a really nasty accident. I have long thought that pneumatic tyres were an unacceptable safety risk. A driver expects stability and then all the air comes out without warning. . . . . . Nasty. I can't understand what people were thinking. Solid tyres would be much safer
(it's a joke, people , those who visit the Aussy forum may know what it's about )

Ian,
It was actually because I didn't have bead locks on my wets.....big NO NO in our rules. We all should respect the rules, they are there for a reason. I was on a borrowed set of rims...should have known better, no excuse.  _________________ www.samzavaglia.com |

I'm wondering why Av Gas? In every test we have conducted, Av gas is slower, significantly. _________________ If the data does not support the theory, get a new theory. (Al Nunley)

Hi Al
Of course you have to optimise for whatever fuel you are using, just sounds like you missed the sweet spot with the Avgas. Also which type of Avgas were you using?
Like all fuels it has advantages and disadvantages, but in the end it's the overall performance that matters and it's what the guys are used to.
Anyway, by using "slow" fuel at least we are giving the other boys a fighting chance
Sam you just brought another safety point to mind, bead locks can not only be ommitted in error, but can strip and fall out, with disasterous consequences. Pneumatic tyres . . . . I should cocoa!!
Best Regards

Well don't mind me . . . . . . but why the heck not
Perhaps a little technical content with your comparitive test results would make a compelling and interesting discussion piece for the observers and contributors to this forum.
Personally, I like it. I know exactly how to get the best out of it, I know how it stacks up on the dyno and track against Euro unleaded race fuels, the lightning fast burners like MS109 and the leaded race fuels the likes of C12, etc.
Why?? you ask. It's an educated and informed choice taking into account all pertinent factors.
Best Regards

AVGAS offers very good properties against detonation, even though it burns slower than unleaded.
AVGAS is half the cost of Unleaded.
AVGAS 100/130 vs AVGAS 100LL are the same.......on paper specs other than the colour. Green vs Blue.
AVGAS is made so planes aren't suppose to fall out the sky. _________________ www.samzavaglia.com |

Why in the world would it be different? US to Euro. And do you have a link for that information?
All I know is that we tested it and it was slower.
On your dyno testing did you have an EGT gauge?
Is your compression ratio stock?
Do you know what Octane means?
And you say it’s cheaper? Sure isn’t here, last time I looked. _________________ If the data does not support the theory, get a new theory. (Al Nunley)

So what is stock compression ratio on our engines? They come with every combo you could dream of...... and programable ignitions and many different pipes.

AVGAS = approx $3.50 per litre
Racing Unleaded >$7.00 per litre

AVGAS 100 (Green)
http://www.msds.bp.com.au/msds.aspx?msdsno=SAV2104-AU
AVGAS 100LL (Blue)
http://www.msds.bp.com.au/msds.aspx?msdsno=SAV2103A-AU
AVGAS also provides greater resistance to engine seizure in 2 strokes as compared to using a Unleaded fuel (dry). It also provides a wider/safer window of tune/jetting as compared to unleaded.
Australian rules only allow fuels in Superkarts as; AVGAS, pump unleaded or FIA Race Unleaded (102RON/100MON)
There is no right or wrong, each to their own....... _________________ www.samzavaglia.com |

Sorry don't have more then this, it's just know around airplane people. but this is little snippet:
http://www.aopa.org/aircraft/articles/2012/120322lycoming-seeks-unleaded-approval-for-euro-fleet.html
BTW if you had followed what is now MotoGp, back in the day when it was 500s and 250s, they made they made the switch from race leaded to unleaded and it did not take very long to get and new combustion camber shape right and some other tuning to make just as much power as the older lead bikes did. |
