Hey everyone, we now live in a world where multiple people will make you a billet water block that’ll handle upwards of 4,500hp. What was once the realm of one-off lunatics and dreamers has become an actual market place for insanely powerful engine that will see street use for endurance drag racing events and lord knows whatever else. Steve Morris can make you an SMX, Noonan can make you a water jacketed Hemi, and now Alan Johnson can make you a 481H20 as well. Incredible but if there were not a market there would not be multiple people in this pool, right?
So let’s get to the work at hand here and talk about what you are going to see in this video. The engine being run on the dyno is the SMX, basically an updated, modified, and water jacketed version of the 481X that has been a force in drag racing for a long, long time. Morris made changes to some of the structure of the block in order to get cooling involved which means that typical 481X parts (like heads) are not going to bolt onto this block.
The mountain of alumimum, tendrils of fuel, cooling, and wiring, and tightly tucked turbos make this thing look like something right out of the movie but man is it great. You’ll see it making 2,000hp and barely seeing any boost. As mentioned above, in full emergency wartime power mode this monster will make upwards of 4,500hp. Good gravy.
