Australian Belly Tank

[Milwaukee Midget]

Okay, but there are new gears in place, and the goal is a hat.  How tight are you going to have to wind it to get red headgear?  Seems the issues were above 6K.  You might be able to put a hat on while babying the engine.   

I know - what fun is that . . .

[Dr Goggles]

No fun at all.

OK. We have a bunch of different roller rockers, the problems are not necessarily simple, and that's me saying it....I have nothing to do with the farnarkling that needs to be done. The Colonel has very good resources he can call on who have been doing special order type stuff their whole lives....right now the issue is room, enough strength, enough slot and enough accuracy. The Colonel at last report said he was having trouble with the current set-up traveling too far across the valve tip. Whether he sorts that issue or not there are a set of Manley extreme duty valves going into the heads, as for springs he says there ain't much on offer over what we have....... On the really bright side he put a BF magnet in the sump and it came out clean as a whistle after the dyno work when the motor was first assembled, he seems to think I'll have trouble breaking this one.

So, assuming full hook up which we have enjoyed up to 195mph we are looking at 211mph for the 2.56 gear set and 224 mph for the 2.41 gear set if we rev it to 6500rpm which is where it went to on the dyno, shame is the curve was pointing upwards in a pretty serious fashion there....

I have to build a push bar that will all be hidden in the tail, I will fashion an exhaust augmenter which will function as the push point, it's currently on the draughting board in my head.

Average Daily Max Temp at Tarcoola north of Lake G for December was 42.8 degree C = 109.04 degree F.

See you there in Feb Doc

By the right rockers and put the 2.73 in it  and "GITER DONE----I know, I know, I ain't pay'n the bills 


If you have the good heads on this thing  I will bet she would not fall off bad untill north of 8500

[Dr Goggles]

Got cracking this morning and came up with this, pictured here with the chute bucket and exhaust in place ..so that's the set up in the tail minus the skin...



now you might notice that I have what looks like an exhaust augmenter in place....well, we can call it that, more importantly I figured it was the neatest way of making a push point, I figure I'll just get some cheap bearings as rollers that I can mount on either side of the tube...

Needs a bit more bracing up the front here, but as it is it rings, so it's feeling pretty stiff.



We'll see about 8500rpm Bill, and I'll see you at the salt Pete.

Haven't quite decided how I'll space the outside tube, won't be hard....

Looking good Goggles, hope that's a SFI, ocky strap.

Have you been using all 4 gears, for some reason I thought you were starting in 2nd.


Cheers

Are you going to wrap that loooong tailpipe??

[grumm441]

Are you going to wrap that loooong tailpipe??

That might be a good idea
I might get some wrap from work
It runs real nice with that loooong tailpipe

Am I missing something, where is the chute being located,sure don't want it around any heat source.Just wondering.

[Dr Goggles]

We've always started in 2nd,and although I thiunk the new diff ratio will mean we still have a lower final drive in first now that we will go for a little push because this is a pretty highly strung motor.

I have worked out a way to spring load the lock out on first gear( we have a two stick shift), thing is when it releases it makes a sound like an anvil landing on Wile E Coyote's head....that should keep the bystanders at the start line happy......

And yes Colonel you get that wrap.........I da Colonel and I in da hou :cheers:se!

You can see the chute doors in this shot Glen, just behind the circular hole you can see the gap between the doors and the clasp, the pilot goes straight up, the chute works well and the lines have a kevlar shroud where it reaches the tailpipe.

[Glen]

Cool, thanks, I remember now.

[Rex Schimmer]

That is probably the very best way to "throw out the laundry" kick the pilot up into the air stream and then let it pull the main out. This is the "Blue" preferred method, planning to do the same on my little car.

Doc, your car does really have a nice "rear end treatment"!

Rex

[Milwaukee Midget]

Rex, it's beyond that.

We joke around a lot, but Doc, the SOS is just about the pinnacle of what a 21st century Bellytank should be.  

I was thumbing through the 2010 Annual, which presents this car so well.

1. The stance is absolutely correct.
2. The lines are gorgeous.
3. The choice of a Canberra tank as a starting point was inspired - a cold war nod to its WWII predecessors.
4. Despite the difficulties, I think the engine choice will eventually prove to be fast and reliable - AND flexible enough to consider fuel and/or supercharging in years down the road.

We can all pick apart our rides - woulda/shoulda/coulda, and I know - it's thrash time, it needs paint, blah, blah, blah, it all seems daunting a month out from Garidner.

But damnitall, this is a world class lakester you guys have put together.  Don't ever lose site of that.

Chris, I needed that right now.

Making the push bar
 
1./ rigid enough so it won't flex and damage the rear bodywork when it is loaded.,

2./ strong enough with the few direct sight lines I have to the rear superstructure.

3./ small enough so the tail can be removed..


Is doing my head in.

I'm putting the attachment points on for the piece of 4 inch pipe on (the actual push point) and just realised they won't clear the opening in the tail.......

Hungry, thirsty, weld burnt and I have to say feelin a bit sore and p'd off right now......

Thanks mate.
