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

With the com­mon-rail Cum­mins in­stalled the Green­speed Re­search truck is in line and ready to go early Fri­day morn­ing on the last day of the 2017 Speed Week. No­tice the slo­gan on the tail­gate, ‘Green Thumb, Lead Foot’; run­ning a diesel en­gine sure makes...

There was a lot of scram­bling in the Green­speed Re­search pits as the team tried to make a go of run­ning the bio-diesel pow­ered 12-valve Cum­mins be­fore even­tu­ally giv­ing up and swap­ping the com­mon-rail Cum­mins back into the truck all right there on the...
