GREEN SPEED RESEARCH USES CUMMINS-POWERED S-10 TO SET NEW DIESEL LAND SPEED RECORD
The Latest News from Around the Industry
Building on the vegetable oil-based biodiesel record of 209 MPH that the Greenspeed Research team set in the past, they packed up and headed back to the Bonneville Salt Flats in Wendover, Utah, in August 2017. This year marked the 69th annual Southern California Timing Association’s Speed Week Event, where competitors from all walks of life with all manner of vehicle attempt to set new land-speed records in various classes.
The team from Greenspeed hoped to break their existing record for biodiesel with a 12V Cummins then planned to swap it out for a common-rail Cummins to run straight No. 2 diesel and break the existing record in that category. They were able to dyno tune and test for the common-rail assault on the salt, but ran out of time to test the 12-valve combination before their trek down to Utah from Idaho. Still hoping to break two records in one weekend the team spent the first two days of Speed Week trying to get it up and running properly before they gave up and swapped over to the common-rail Cummins.
Thursday morning they had the common-rail Cummins installed and they were ready to make their first attempt at setting a new record. But, it was not to be as Dave Schenker was flying along at around 140 MPH he suffered a blow out of the right rear tire in a scary moment. Fortunately, the S-10 Chevy did not suffer any serious damage, but the team had a hard time finding a replacement tire. They found another tire and gave the truck a clean bill of health for another run but missed the final Thursday starting spot by about 15 minutes.
With Friday and the final day of 2017 Speed Week competition looming the team lined up early for a pass on Friday morning. Schenker strapped in and began his run down the course then the truck was impounded by officials to cool down before the return pass. After the return pass it was confirmed that Schenker and the Greenspeed Research team had surpassed the previous diesel truck land speed record of that stood for 10 years at 215.091 MPH with a new average speed of 219.411 MPH down the 5-mile course and back.
The modified Chevrolet S-10 pickup is powered by a Cummins engine that delivers 917 SAE rated HP with mild EFILIVE tuning in its current state. They feel that the truck has the capability of running between 235-240 MPH in its current form and they plan to push it toward that level next year. Can the team squeeze another 20 MPH out of the truck? We hope so and look forward to cheering them on as they try. Stay tuned to future issues of Ultimatedieselbuilder’sguide as we plan to run an in-depth feature on the truck. UDBG
