Land Speed Record Vehikel
The Land Speed Record Vehicle (LSRV) Project was conceived as a special project that all the members of the Boeing Employees� Racing Club could become involved in regardless of their individual racing endeavors.

A review of the Southern California Timing Association�s 1997 Rule Book revealed that the smallest displacement classification for a world record was for 50 cc motorcycles and that the all out record was set in 1956 for a 50cc Streamliner, Blown on Fuel (S-BF) at 121.700 mph with an NSU motorcycle. It was also noted that the 100cc S-BF and 125cc S-BF records had also been set in 1956 using an NSU motorcycle. After an initial aerodynamic feasibility study by Eric Kaduce it was determined that not only was it possible to break the existing 50cc S-BF record but that it could be shattered with a theoretical maximum speed of over 180 mph. Based on this potential, along with the option of also using the same vehicle for future attempts in the 100cc S-BF and 125cc S-BF categories, the decision was made to go ahead with the project.

After a review of three different proposed LSRV configurations (i.e. prone rider, kneeling rider and supine position), the supine position was selected. Alan Wong is the Chief Design Engineer on the body and chassis and is working with Rex Walter who has assumed responsibility for the overall aero-dynamics and scale model wind tunnel testing of the LSRV.

Several considerations made engine selection interesting. It was decided that a highly modified 50cc Honda engine with a Hansen HSC V-12 supercharger would be used. Rocky Jewel is the LSRV Chief Mechanic and will be responsible for engine selection and performance. We would also like to thank Craig Hansen of Hansen Superchargers for providing technical support for the application of their supercharger. To meet the "fuel" category we have decided to run a nitrous oxide system (per STCA rules) that has been graciously donated for the project by Mike Wood of Nitrous Express.

In addition, we�ve selected two tires from Goodyear for the LSRV. The rear tire is an true land speed record tire offered by Goodyear and the front tire is one of the small Top Fuel dragster tires also offered by Goodyear. Both tires are rated at over 300 MPH so we should be OK here.

Simon-Pierre Smith is the Chief Test Pilot of the LSRV and the overall program focal working with Racing Club President, Dennis L. Johnson.

Testing of the vehicle and the engine continue. We currently plan on making the 50 cc S-BF Land Speed Record runs in 1999 at Bonneville during Speedweek. Possible 100 cc S-BF (current record 138 mph) and 125 cc S-BF (current record 150 mph) attempts are scheduled to follow. The LSRV�s superior aerodynamic design and our horsepower potential should allow us to reset all three existing records within the next three years.

The body is a fiberglass monocoque design was built by Dennis Johnson and Tim Sanders is providing general fabrication support for the project.

This design is based on a solid laminate with internal annular rings. The extreme fibers are to be stabilized by fore-n-aft shear beams inclusive of the sill beams alongside of the driver. The canopy in nonstructural and is only attached with a forward flush mounted hinge and two externally flush mounted latches with inside emergency release pins for the driver.

It has been determined that honeycomb of the structure is probably not required to stiffen the exterior. The reason being that with enough inner and outer plies to prevent reasonable impact damage, the gages alone required should be sufficient to carry the load with minimum deflection considering the shape stiffened nature of the vehicle.
