Watch Quad-Turbo 12.3L V-16 Make 4,500 HP on the Dyno

Custom-designed engine destined for Devel Sixteen supercar.

When videos of the Devel Sixteen surfaced a few years ago, many people thought the 5,000-hp, Dubai-designed supercar was merely vaporware. Now, new videos have surfaced of the engine that will power the beast.

The first video shows the dyno pulls of the massive quad-turbo 12.36-liter (754-cubic-inch) V-16 engine on race fuel and pump gas. On race fuel, the engine makes 4,515 hp at 6,900 rpm and 3,519 lb-ft of torque at 36 psi of boost. In street mode, the engine makes 3,006 hp at 6,900 rpm and 2,807 lb-ft on just 20 psi of boost. The street pulls were made on 92- to 93-octane fuel.

In the second video, Steve Morris of Steve Morris Engines (SME) details the design of the bespoke engine. The engine features a custom one-piece billet block with one-piece billet heads, camshaft, and crankshaft. Designed around an overhead valve, cam-in-block design, the heads feature two valves per cylinder. Each cylinder features one fuel injector mounted into the intake manifold. Although not based on an existing engine, Morris says the engine is heavily "influenced" by the Chevrolet LS and the big-block Chevy V-8 engines. The engine features five stages of oiling: four for the engine and one for the quartet of bespoke 81-mm turbos. SME has invested more than 2,000 hours of machine work into the engine and expects more before it goes into production.

Check out the videos of the powerplant destined for the Devel Sixteen. For more information, check out this post over at Hot Rod Magazine.
