CRAZY DIAMOND PERFORMANCE TO DEVELOP 7.4L CNG ENGINE

Crazy Diamond Performance (CDP), a Michigan-based fuel system engineering and integration company, announced it has begun developing a supercharged 7.4L CNG Torquemaster engine. The new engine will be designed from the ground up and will be based on the GM LS engine architecture. The 7.4L will stand alongside the CDP 6.9L Torquemaster engine, both of which are designed for applications up to Class 6. These include school bus and chassis/strip chassis applications. “The 7.4L engine is a dual injector application, which is a bit different to what’s in the market currently,” states Kevin Fern president CDP. The cylinder heads include lightweight stainless valves and hardened valve seats. CDP will begin its testing of the new 7.4L engine Q4 2014.
