I shall have to dig out the McLaren book to see what they're going to subject that poor old Bedford diff to.
An M8 should be 176hp, but at maximum revs of only 1,000rpm the torque will be something else!

No room for an M8 in here anyway (this a M2 - there's 4 of the same blocks on the 8) :D

Completely bonkers. Racetrack & race cars with pedestrians, cyclists, tractors…

nowt wrong with the engine sound, though a flat twelve (Porsche), flat six (ditto), v6 (Stratos) or v twin (Guzzi) would be my choices…

I recall my mates and I drooling over these when we first saw the photo's of it, it must of been '73 of coarse, but no one had the money then to buy one anyway !
But the café racer scene held sway and we carried on building basket case Tritons :D .

Nick, where did you get this fine example mate ?

In all seriousness I think that they are getting beyond the limit of the mechanical strength of a diesel engine of that pure physical size. A bit like trying to get a prop driven fighter ( Corsairs and Mustangs etc. ) to go faster than 500 mph, not possible.
Racing trucks are on a limit of 1,200 H.P.
This guy was trying for 3000 H.P. on a diesel but really you need engines as fitted to railway loco's to stay in one piece. The drag cars are different running petrol engines on nitromethane and methanol but even they implode occasionally.

Question of time.

The old aero petrol engines could be fitted with water injection to suppress knock, and with high octane petrol and very high boost pressures could develop extraordinary power, normally for take-off with big bomb loads and full tanks, but the engine life was measured in minutes. It was necessary to resort to normal conditions for the rest of the flight (not to mention the fuel consumption).

Diesels don’t go round fast, so they have to have big torque to give headline horsepower.

not sure what you do with a 3kHp pickup truck. Probably wheelspin as you exit each bend. And burn a lot of gas.

power to weight? Gas turbine or two stroke :)
