Alex Esnaola from Steve Morris Engines tells Autoblog that the fabled 5,000 horsepower "wouldn't take much more boost" from the 12.36-liter (754-cubic-inch) turbocharged V16. The company intends gradually to work up to that point over many more dyno pulls to develop the mill into a working prototype. The experimental powerplant features many unique, one-piece billet parts that wouldn't be easy to replace. For example, the crankshaft alone took about seven and a half months to make, Esnaola said.
The Devel Sixteen's performance claims of zapping to 62 miles per hour in 1.8 seconds and a 348 mile-per-hour top speed still seem lofty. However, maybe we shouldn't completely write off the stats with such a powerful engine deep into development.
