Here’s a sweet looking 2 liter V8 called the Cyclone Y40R. Specs on the website are 302 horsepower, 167 foot pounds at 8500rpm and 108 foot pounds at only 2000 rpm. This is with a standard carb setup and they have photos of a fuel injected version but no power figures yet. It looks similar in size to the Hayabusa V8 with a bit less power.
The web site has very little information so beyond what I’ve mentioned, it’s a bit sketchy. They show the engine installed in a sort of Lotus or Caterham type car called the Quantum Extreme, and speak in general terms about the whole project.
How long has this engine existed? Is this old news or a brand new small displacement V8? Guess we’ll have to follow up a bit to see what it’s all about. If you have more information on this company or project, fill us in.
