JCB Dieselmax sets new diesel Bonneville speed record

The JCB-sponsored, twin-engined Dieselmax streamliner set a new Bonneville Speed Week record for diesel-powered vehicles, with a two-run average speed of 317 mph.

Under the Southern California Timing Association (the Bonneville Speed Week sanctioning body) rules, breaking a record requires an average of two runs, which must be completed within 24 hours. The Dieselmax sped through the measured mile on Thursday at 308 mph, and then again Friday at 325 mph, for a record-setting 317 mph average.

The SCTA Speed Week is followed at the salt flats by the FIA-sanctioned speed trials, where the JCB team hopes to set an international land speed record. The more demanding FIA rules require two runs in the span of only an hour. The Dieselmax will be fitted with specially-prepared 750 hp JCB444-LSR "record" engines for the attempt.

Diesel land speed record car based on construction machinery

British construction equipment manufacturer JCB aims to set a new diesel land speed record with this Bonneville streamliner powered by two backhoe engines. Really. The JCB Dieselmax H1 is motivated by a pair of JCB444 diesels normally used with the company's backhoe models.

The firm announced Thursday that the streamliner is scheduled for an August attempt to break the 33-year-old diesel speed record of 235.756 mph, set by Virgil Snyder in the Thermo King Streamliner. The Dieselmax will be driven by Britain's own Andy Green, holder of the unlimited land speed record.

The two LSR four-cylinder diesels use a standard production engine block, cylinder head and bedplate, upgraded with direct injection, two-stage turbocharging and a host of other mods to boost power output to 750 hp. Redlined at 3800 rpm, each engine produces nearly 1,100 ft-lb of torque. The engines will run with about 75 psi (!) of boost at full power. At 150 hp/liter, JCB claims the Dieselmax engines are the world's highest specific power diesel car engines.
