http://autospeed.drive.com.au/cms/A_2962/article.html JCB, the fifth largest manufacturer of construction equipment in the world, will make a land speed record attempt this August in a bid to earn its purpose-designed streamliner car the title of "World's Fastest Diesel". To reach speeds of over 300 mph (480 km/h), JCB has developed the world's most powerful automotive diesel engine, with a specific power of 150hp per litre. The aim is to set a new record in excess of 300 mph. The current FIA mark stands at 235.756 mph to Virgil W Snyder and the Thermo King Streamliner, a record that dates back to 1973. The JCB DIESELMAX streamliner will be driven by Wing Commander Andy Green, who set the first-ever supersonic world land speed record at 763.035 mph in ThrustSSC on the Black Rock Desert on 15 October 1997. The innovative car has been designed by a team led by JCB Group Engineering Director Dr Tim Leverton. Richard Noble, the former land speed record-holder, has acted as a consultant to the project, and JCB has worked with long-term technology partner Ricardo plc to develop the JCB444-LSR engine. The record attempt will be made at the Bonneville Salt Flats. Technical Specifications Engine: Two JCB444-LSR common-rail injection diesels, bored and stroked to 5000 cc, dry-sumped and inclined at 10 degrees. Two-stage turbo-chargers with intercooling and after cooling Ice tank cooling (capacity 200 litres). Power: 750hp (560 kW) at 3800 rpm Torque: 1105 lb ft (1500 Nm) at 2500 rpm Fuel tank capacity: 9 litres Transmission: Forward transmission and final drive connected to forward engine; rear transmission and final drive unit connected to rear engine. Six-speed barrel-shift transmissions driven through torsional dampers and oil-immersed multi-plate clutches. Steering: Rack and pinion, to front wheels Brakes: Split circuit; unique design carbon rotors and twin stators. Exhaust brakes for front and rear engines, manually operated. Twin parachutes. Suspension: Independent all round via twin wishbones, coil springs and hydraulic dampers. Chassis: Hybrid square steel tube spaceframe with bonded carbon composite panels Body: Aerodynamically designed (CdA <0.15); carbon composite materials Wheels and tyres: 23 x 15 Dimensions Length: 9091 mm Width: 1145 mm Height: 979 mm (to top of canopy, at run speed) 1337 mm (to top of fin) Front track: 800 mm Rear track: 600 mm Wheelbase: 5878 mm Weight: 2700 kg including fuel, oil, ice and water coolant and driver  SignatureRegards Dan Heaven is Hell.

I read it as 750hp / 2. 750hp is pretty respectable.

Don't know about the Supra's, but the Skylines seem pretty tough. -- Regards, Noddy. >> I wonder in comparisons just how tuff and long lasting they are ? >> I have seen a couple of locals with them and the maintenance is pretty high. > > Don't know about the Supra's, but the Skylines seem pretty tough. The Supras are known for their toughness. 600hp on a standard bottom end is pretty common. Even at 1000hp they don't bother changing the Getrag 6 speeds in them.

Both my Skylines were fine at about that much boost.

Yep. With shitloads of torque. > 750hp @ 3800RPM > how long would this engine last compared to a screaming Banshee It's a diesel so of course it is low revving. Who knows which would last longer. The diesels are made for top speed runs. So they aren't made to last forever.

My RC race car, is a diesel 2 stroke running on methanol and nitromethane. 600hp per litre. Try again JCB. PS yes I know they mean a diesel engine running on *diesel*, it's just that 600hp/L gives me a woody and I like typing it 600hp/L 600hp/L 600hp/L 600hp/L Of course they can, when they're carried in the back of a decent wagon or ute :-) |
