For many years Steve Morris has been working on a quad-turbo V16 engine for the Devel Sixteen supercar. The 748 ci (12,258 cc) V16 features a one-piece billet block, one-piece solid roller camshaft, crank (fires every 45 degrees), four heads, and four 81 mm turbochargers. Steve released a video two years ago when the engine hit the dyno limit at 4,500 hp. Steve recently put the monster engine back on the dyno showing it produce 5,007 horsepower and 3,757 lb-ft of torque at 7,000 rpm on 44 psi of boost.

Is the Devel 16 still a thing? Maybe Morris has decided to carry on and not waste his investment, even if the people who wanted to make the car have flaked out.
I could see a naturally aspirated version finding its way into some custom vehicles. Jay Leno probably has the perfect project for it.
this engine looks like the real deal, but the car itself (last time I saw short videos of it) looked like some 12 year old’s scribble. Not like something that could surive 1000 hp, let alone 5000 hp… half the bodywork is so flimsey it’d rip off above 200 kph
