Would you simply divide the V-8 figures by two to get whet you need?

Those wheels look 4 inches diameter.  What are they used on?

I wonder what these guys are trying to do at 15000 rpm

Downloaded the Holley EFI software tonight.  Hoping to find a file somewhere of ANY 4-cylinder application to monkey around with, but - as I was warned - Holley's resources are OVERTLY V-8 centric. 

So I'll by playing around with the MAP for a Small Block Chevy tonight, and try to get a feel for how the software works without the luxury - or annoyance - of a small block.

The stock frame would run in modified assuming you do not extend the swingarm more than 10%.  Take a close look at the rule book and the class records, as you will be running against some very fast two-stroke records.  The modified record is 137 without any bodywork and the altered class will be 142.  If you run a fairing, both will be in the mid 150s.

And, now that I read back, a contained heatsink in the fuel tank was mentioned previously. The NZ team did that, I think, in  their bastardised BMW A-series (Heretics! Witches!), to excellent effect.

What would you do? Put the coolant water in the fuel tank and fuel in the now-redundant front radiator, so you have combustion fuel tank and fuel cooler in one? Voila! Possibly doesn't meet crash, though.

I also draw great encouragement from this forum; the focus on The Main Chance, as you say, is the thing. The car doesn't need to burn fifteen gallons, does it; you're only on the motor for, what, two minutes? Two litres of fuel burned? Did you say, 250litres/h for your Mustang pump?
 If it does a quarter of that against internal restrictions and 5bar that's still a vigorous recirc ratio. Not much chance for recirc fuel to do harm there unless you're only carrying single-figure litres. (Do I remember eg NASCAR fuel tank size limits overcome with generously-sized fuel pipes..?)

It is this, isn't it; Just do The Job; don't do anything else. It is like speaking to a policeman, in which we answer the question politely then shut up. I hadn't though of the salt as a copper but it does seem to be a place that exposes assumptions, underlines the truth and finds out when marks are overstepped. Blimey. I sound like Bruce Brown.

I also read in the trail that the queue for the start line (long enough to be seen from space, i imagine) is a couple or three hours long. That's where the infamous ice goes, I guess.

I am greatly entertained by the conversation; I fell about this morning when I saw your post. Too many bolts, forsooth. We invented thread standardisation, you know, and it's good to celebrate achievement so  there's no such thing as too many bolts!

I have been helping a mate here in Australia with an air head BMW for the same class.
It looks like you have taken a chain off the diff to the rear wheel. Unfortunately a lot of HP is used in the diff.
My mate has turned the engine 90* and used a TT Industries Norton box with a belt primary.
Turning the engine has not helped the width but it is a more efficient drive train.
Last year at Gairdner he ran a very easy 135.
We will see how it goes in a few weeks.

Like Wobbly said-- If you could move your foot rests back and also your seat, you may be able
to flatten your back, better aero,
I will get a picture and see how I go loading it.

cheers     Bones

More videos demonstrating the same Gyroscopic Precession Affect. So what does this do to a car traveling at high speed? Does it want to make the wheels lift up and rotate like shown in the videos?

1. holding a 3 foot long axle with a 40 pound 12" steel wheel spinning at high speed and lifting the device over head

2. holding the same device and standing on a weight scale.

3. Forces causing Gyroscopic Precession explained.

"If the gyroscope/engine is spinning at a fairly high speed in a clockwise direction, as seen from the back of the car and as shown in the diagram above. When the car is turned to the right (clockwise from above) forces A and B are applied to the structure of the car forcing the front end of the car down and the back end up. If the car is turned to the left then the front end of the car is forced up and the back end forced down. If the gyroscope is spinning in the opposite direction then the reverse will happen."
