Hi Don, Firstly you'll need to get your Spitfire engine
The Mechanics
- Merlin 27,000cc V12 engine
- Custom ‘step up’ GM Turbo 400 three-speed auto
- Austin Westminster steering
- Bespoke rear suspension
- Currie heavy duty rear axle
The Beast gets its name not only from its Brobdingnagian proportions, but also from the huge Merlin V12 that powers it. In the case of The Beast, the engine is naturally aspirated, not supercharged, and is speculated to produce approx. 750bhp. When it comes to the specs, there is a lot ‘estimated’. It’s never been on a rolling road, for example. However, the ‘stock’ engine with a supercharger could deliver 1,500bhp, so 750 doesn’t seem far-fetched. And, in 1973, the RAC verified a top speed run of 183mph, so it’s no slouch. When The Beast was featured in
evo magazine, John boldly claimed 950bhp with an earth-turning 760lb ft of torque. Having never been on a rolling road, it's difficult to pin an exact figure to it, but it's a lot no matter how you look at it.
