Twin streamliners

from 1964:

The Sprint engine was installed in the smaller streamliner. This is the chassis that is the same size as the one that ran 214 mph and was raced in 1958. Its fiberglass shell, which is 14 feet long, approximately 1/8-inch thick and weighs 68 pounds, is mounted on a frame that has a wheelbase of 96 inches. The frame was fabricated from 3/4-inch-OD, 0.040-inch-wall, 4130 chrome-moly tubing. It has two main members on each side, spaced 7-1/2 inches apart, center to center, that extend from its front end to its rear end. These members follow the contour of the shell. At the frame’s front end those for the right and left sides are separated a few inches, but at the rear they were brought together to give the frame’s rear end a wedge shape. Measured from the ground to its highest point, the bike is 34 inches high.

Stormy’s number two bike, in which the 55-inch Sportster was installed, is larger than the smaller bike and heavier and stronger in all respects. Its fiberglass shell is 15 feet, 7-1/2 inches long and weighs 120 pounds. The shell’s lines and proportions are exactly the same as those for the smaller bike but scaled up slightly to fit the longer 112-inch wheelbase. Its wheels, brakes, and tires are identical to those on the smaller bike but because of the greater speed it will run, it has a drag chute that will help it stop. Its frame was fabricated from 3/4-inch OD, .073-inch-wall, 4130 tubing. Spacing of the main members on each of the frame’s sides is 7-1/4 inches center to center, the same as for the smaller bike, and the frame’s shape is similar to that for the smaller bike.

Gears are a good thing…

For the Bonneville Salt Flats, one needs to make some serious gearing changes between gearbox and sprockets to make things work. For a customer project, need to change the gearing itself to allow from 0 to 280mph+ across several miles. More on this upcoming but here is what the parts from within a 916SPS Ducati gearbox look like.

Cycle Magazine — December 1969

A gift from an old friend who has been at Bonneville for more decades then I’ve actually been around. I will get it framed and hung on the wall for all the Bonneville Salt Flat enthusiasts and friends to share. This is a very large sized print he made of the master slide of the photograph he took at the 1969 Bonneville Salt Flats and that was used on the cover of the December 1969 issue of Cycle Magazine. Admittedly it is not of Ducati content — but still cool regardless. Thank you!

SpeedAero

SpeedAero is a customer project for Bonneville in the years ahead. CAD work is underway given the multiple engines, fuel systems, water reservoirs (no radiators) and drive system to couple the engines together along with a CFD designed fuselage that already has had some testing in a F1 UK wind tunnel by friends several months ago. The goal is 250mph and normally aspirated.

Two customer Monster projects need to be finished (and delivered) in the next several weeks between new finalized CAD/CNC machined aluminum parts and the new BossaBoma exhaust system debut. Then SpeedAero will take their place upon the fabrication and service bench until finished.

Here is a general overhead view:

Bonneville SpeedWeek 2016

Speedweek is like a family reunion with a family that you actually want to hang out with. There is never enough time to visit with all the folks that you look forward to seeing every year. I had some nice long visits with many old friends and several new ones on the Salt itself. And best of all exposed some newbies to that thing called “Salt Fever” — which they are now infected by as well. Hopefully it isn’t three more years until we are all hanging out on the Bonneville Salt Flats again. And most importantly I hope everyone made it home safe!

Video: 5000 horsepower from two methanol snorting supercharged HEMI engines. 8000lbs. 43 feet in length. 4-wheel drive. Definitely not a Ducati but all gearheads would relate to a Bonneville streamliner that has 60,000+ hours of fabrication time to actually construct it over a decade plus. Still testing mode but there is plenty of potential in the future for this.
