The engine was available through mid-1965, when it was replaced by the 396 cu in (6.5 L) 375 hp (280 kW) Mark IV big-block engine. In addition, a 340 hp (254 kW) version of the 409 engine was available from 1963 to 1965, with a single 4-barrel cast iron intake mounting a Rochester 4GC square-bore carburetor, and hydraulic lifters.
Dieseling or engine run-on is a condition that can occur in spark-plug-ignited, gasoline-powered internal combustion engines, whereby the engine keeps running for a short period after being turned off, drawing fuel through the carburetor, into the engine and igniting it without a spark.
The RB engines, produced from 1959 to 1979, are raised-block (taller) versions of the B engines. All RB engines have a 3 + 3 ⁄ 4 in (95.3 mm) stroke, with the bore being the defining factor in engine size. All RB wedge engines share a deck height of 10.725 in (272.4 mm), and were fitted with 6.768 in (171.9 mm) long connecting rods, resulting ...
The Supra was pushing almost 1000 horsepower before its crash, a source said. Social media commenters who claim to be familiar with the build say the car had just over 17,000 miles on the clock.
Although a powerful engine for its time, the 16 Valve engine can experience some problems that can be solved easily. One of the few problems is oil pump gear problems leading to broken timing belts. The oil pump gear itself can fail around the mounting flange, or, more often, the weak 8.8 (grade 5) grade bolt holding the gear can break.
This engine had many of the same basic dimensions as one of Austin's pre-war sidevalve engines - the 1125cc engine fitted in the Austin 10 which had the 88.9 mm (3.5 in) stroke common to all later B-Series engines, allowing the use of much of the same installed equipment to produce the block and crankshaft - but to an all-new OHV design.
The Prince family shares its basic block dimensions with the previous PSA TU engine family. Engineering design was directed by BMW using their Valvetronic variable valve lift system on the intake side, flow-controlled oil pump, timing chain, single belt drive of all ancillary units, composite camshafts and cylinder head produced by lost-foam casting.
The road-going engine is rated at 1,000 hp (746 kW; 1,014 PS) at 10,500 rpm, with a max torque figure of 740 N⋅m (546 lbf⋅ft) at 7,000 rpm, making it the most powerful naturally-aspirated engine ever fitted and used in a production road car. [10] The engine also revs to a maximum of 11,100 rpm, and has a power density making 114.8 kW (156.1 ...
