This is cool stuff. Very interesting to me. Did you mention why you don't run a fuel log here?
UltArc,
When this current thread (the transmission/overdrive swap) is complete, I plan on posting fuel numbers from the beginning. When you see the numbers along with the associated notes, the numbers will make sense. Remember, this car has been taken apart, reassembled, quite a few times. Without knowing what was done, the fuel logs mean nothing - zero.
.
Here's a quick example: The 1st fuel log I have is for 88.9mpg. Ok - STOP.
What comments or conclusions might be drawn from just that basic fuel log entry? Followers of the original Centurion and it's 128mpg figure would say this car fell short.
.
Without the notes, the 88.9 mpg is open to interpretation, and it would likely be incorrect. 10 different people = 10 different opinions.
.
When (and if) I end this thread with those numbers, you'll see that the first entry of 88.9 mpg is based on a "new engine" with "warm ups" . There was no glass at all in the car except the windshield. There was the unstoppable 25amp draw of the Kubota dynamo, a misalignment of front toe-in, and more importantly, the rear trailing arms which had to be attached to the frame and shimmed for correctness - thus throwing off the rear alignment. The maiden voyage was only on back roads where 55mph would've been very hard (if not impossible to obtain) and the roads are rough, very twisty, and very hilly to boot. So, without the details the previous fuel log of 88.9mpg doesn't mean much... Or maybe that's just my feeling on this....

The Green Grand Prix on the other hand was worth it's weight in gold. We know so many of the details: course, conditions, car, driver, passenger, mileage, accurate repeatable graduated non-heated fuel tank refill, etc... And, we have an entire fleet of vehicles competing at the same time to compare with! Awesome! So, whatever the number ended up at that event, would certainly be posted.

So, that's where the fuel log is at - most likely being posted in the last closing posts of the Centurion thread somewhere down the road.

As for you beating me at the 2015 GGP.... I would love it if you tied or blew past the current numbers!! They are beatable, and all records are made to be broken - period.

In a couple of minutes, I'll make a separate post of things I jotted down that may (or may not) help anyone, but did apply to Centurion's winning run!
