Last time we talked about engines on dynos we had LaFerrari’s 800 HP mill. Before that, there was a crazy pink Hemi V8 that delivered 802 horses. Well, if you thought those two were impressive, wait until you check out the video we posted below.
Today we are showing you a devilish 572 cubic inch (9.3-liter) big-block from Chevy that’s powerful enough to rip a dyno apart. Fortunately, it’s not the case, but the 2,500+ HP this mill is pumping nearly put an end to Nelson Racing Engine’s testing rig.
So what’s this engine all about? According to DragZine, it’s built around a Dart tall-deck block, Callies Magnum crankshaft, Oliver billet rods and custom-made JE pistons. NRE also used Smith Bros. pushrods, T&D shaft-mounted rocker arms, and Aviad dry-sump system and Brodix 24-degree CNC heads.
According to NRE boss Tom Nelson, the mill can do well beyond its current 2,500 HP: “Personally, I think it could have made 2,800 horsepower, but we called it 2,500 just because everyone will cry about it.”
