The FPV F6 is an automobile that was produced in Australia by Ford Performance Vehicles from 2004 until 2014. It is a high-performance derivative of the Australian Ford Falcon.
The F6 is based on the modern-classic Ford Falcon XR6 Turbo sports sedan. The F6 engine is based on XR6T motor, a turbocharged intercooled DOHC 4.0L Inline Six with VCT, but includes: a modified FPV airbox (with Dual Ram Air intakes), higher strength conrods, larger air-to-air intercooler, high flow exhaust system, higher capacity fuel pump, and a Garrett GT3582r (same as the BA/BF XR6T) turbocharger with an internal waste gate (up from the GT3576r on the FG XR6T) running 0.64 bar of boost on the BA/BF models and 0.91 on the FG. This engine is known for its wide, flat torque curve, with peak torque of 565 N⋅m (417 lb⋅ft) available from 1950 to 5250 rpm (FG F6). This equates to strong acceleration throughout the rev range.
The F6 represented a diversification of sorts for FPV, broadening the reach of the brand to turbo buyers, a typically younger demographic than the V8 buyers that the Australian manufacturers traditionally cater to.
I'm wondering how exactly MCNP calculates an f6 tally? I'm trying to compare a theoretical result with an MCNP f6 tally (MeV/g). I have an initial energy spectrum and a thin layer of lead that attenuates the x-rays. Using the attenuation coefficient at each energy (bin width of 0.5 kev from...
