2010 BONNEVILLE REPORT:
We
got the first of two runs Sunday at 11:52, we did 121.787. The fuel
pressure gauge read zero, when I got back to the pits I turned up the
regulator to give it two pounds.
The second run was 128.678 mph, with 10# of boost at just a hair over 6000 rpms.
Racing
was delayed Monday because of rain Sunday night, and windy conditions. I
turned up the boost to 15#, and went down one size on the intermediate
jet. We made our only run of the day at 3:54. I got it up to 6200 rpms
for a top speed of 132.37, steady improvement. The carb was now
overflowing at low speeds, and the plugs looked rich.
The first run on Tuesday was at 7:53, we did 125.391. The 110 main jet was too big, 5900 rpms. Better too rich than too lean.
We changed to a 106 mj for our second run, and did 128.29. The plugs looked too hot, I went down one heat range.
On
the third run, I went back to our record setting gear ratio by adding
two teeth to the rear sprocket. I was a little too optimistic with the
starting gearing. We also changed to a 102 mj, and we did 133.086 @ 6500
rpms. We are still showing slow but steady improvement.
Wednesday morning at 9:21 the air was nice and thick, and we went to a 104 mj. We did 134.104 at 6400 rpms.
At
1:01 the next run was done with a 106 mj for a speed of 132.935, a
little too rich. The motor just didn’t feel quite right, so I checked
the timing. I found a problem! Somehow the timing was ten degrees too
far advanced. Not enough double checking beforehand.
At 3:52 with 38˚ timing and a 102 mj, we did 134.217. That was our last run for the day, time for a cold one!
On the last day at 7:57 with no adjustments we did 133.069 @ 6300 rpms.
For
the next run at 9:54 I tried a 100 mj, that was a mistake. The motor
wouldn’t tach up, and I let off early. That run was 111.48.
Our
last run was at 12:16, with a 104 mj. The motor felt strong in the
lower gears, but when I got into the measured mile the tach started to
go the wrong direction. I held it open anyway since I knew it would be
our last run, for a top speed of 133.117. When I got back to the pits
and checked things out, the compression on the front cylinder was low,
and on the rear it was gone. I think having the timing off for so many
runs is what did it in. We sure had a lot of fun while it lasted!
And
not to forget our new entry JRV/FRCP Racing. Bob Velloza raced an M2
Buell for the first time in honor of his son Jake, lost in combat May
2nd 2009. Number 621 achieved a very respectable 141 MPH. Not too bad
for the first time out! Jake would be proud!!!!
Thanks again to all of the generous people who helped make this possible. As always, next year will be better!!!
