LAS VEGAS, NV — Your day has come, diesel owners.
The Chevy Diesel Duramax Cylinder Head is another on a list of exciting new products Edelbrock unveiled at the 2015 SEMA Show.
The Edelbrock Duramax diesel cylinder heads have higher flow ratings than stock, but can be bolted directly on as a factory replacement. It increases flow by at least 20 percent and cooling capacity by 40 percent, according to Edelbrock.
Edelbrock used a technique called Hot Isostatic Pressing (HIP) to create the heads. Per Edelbrock’s info sheet, “this aerospace process heats raw aluminum castings up to 900° F in a pressurized chamber (up to 30,000 psi) and compresses the casting to remove any trapped gases and internal porosity. During this process the casting is compressed to eliminate these imperfections. The result is an incredibly strong and dense sand casting that has three times the fatigue life and nearly the consistency of billet aluminum. For the engine builders and racers, HIP-processed cylinder heads provide less chance of failure due to fatigue. They also provide a better, smoother machined surface finish when CNC port and chamber work is applied.”
The only bad news about Edelbrock’s Duramax cylinder head is you probably won’t see it soon. Edelbrock regional account manager Mike Kovacs said the cylinder heads might be available in the second half of 2016.
“We’re done with it, but we’re going to do endurance testing,” Kovacs said. “We want to break it ourselves to see exactly where that failure point is. If I tell you it’s bulletproof, it’s got to be bulletproof. And that’s why they do all the testing.”
