PRI 2012: Mike Moran’s New 4,400hp Billet Aluminum Hemi – Nearing Top Fuel HP With Alky and Turbos!


PRI 2012: Mike Moran’s New 4,400hp Billet Aluminum Hemi – Nearing Top Fuel HP With Alky and Turbos!

Of all the cool, heavy duty, bleeding edge race stuff we saw at the 2012 PRI Show, this single engine was the showstopper. The 637ci Hemi that features a billet aluminum block and billet everything else is a clean sheet design from Mike Moran Racing Engines. The guys with the engine say that this version is capable of making 4,400hp on alcohol with the right turbocharger combination. The crazy thing is? This isn’t the biggest configuration that the engine car be built into. The engine you are looking at features a bore of 4.75-inches and a stroke of 4.5 inches. Since this is a 5.3-inch bore spacing block, there is plenty of room left to open the bores and according to the MRE reps, there is plenty of meat that can be machined out of the bottom end to fit a larger crank. In fact, the fellows will be starting in on a 5-inch bore and 5-inch stroke unit when they get home from their initial rounds with this engine. That’s 785ci for those of you playing at home. Adding to the dizzying levels of awesome this thing exudes, it is capable of being spun upwards of 10,000 RPM with all of that size inside the block. The sounds that must come from it at those RPM levels should border on operatic. Lastly, we’ll say that the engine was built to be serviced. Looking at way the rockers and other components are mounted, they can be replaced relatively quickly during a pit thrash or on the side of the road at Drag Week. Someone NEEDS to load one of these mothers into a Drag Week car!

According to the MRE guys, they have built and sold a few of these already and they have a couple more on order. They’re shipping them all over the world, too. That pretty neat. We didn’t ask what the price is because frankly, we can’t afford it. If it is less than $100,000 for a complete engine we’d be surprised. Just looking at the machining that is involved in simply whittling the massive heads, block, valve covers, etc before one even gets into the price of the parts that fill those cavities, its is big money.

We’ll leave you with some photos of the coolest engine we saw at all of PRI…and that is saying something because the place is crawling with them!

      Totally! Will they build their own turbos like Nelson Racing Engines? The videos of their all billet are impressive.

    Mike Walsh,surely you cant be serious,one brand of engine is not reliable as compared to others? Give your head a shake,but not too hard or more damage could result! Dont know if you follow other forms of racing,but the Cup was won in Nascar by Dodge this year, surprise,surprise,so I guess the team with the smallest factory funding was running the least reliable engine program in the series???Guessing the other teams(Chevy,Ford,Toyota )must just have had some bad luck,bad pitstops,bad crew chiefs,poor driving,cant have been anything to do with engine programs or branding,but everyone is entitled to an opinion,even if it is wrong!
