What does it take to build a 4 cylinder engine capable of an insane 2,000 horsepower? This custom-built drag racer has a flat-4 specially designed by the owner. This unique engine was enough to give this Brazilian racing team the title of the most powerful 4 cylinder engine dyno’d has ever seen.
The team at FuelTech USA manufactures some of the highest quality fuel system components for your modified road and racing car. To showcase their technology in action, FuelTech USA has a YouTube channel where they showcase buildings that use their fuel system components to produce impressive results.
Today’s feature by FuelTech USA is a record-breaking drag racer set by the Brazilian drag racing team. This drag racer uses an air-cooled VW flat-4 engine redesigned by its owner to create the most powerful four-cylinder engine ever. The creation of this engine was a personal project of the owner who spent years turning a humble air-cooled flat-4 into a legit drag racing powerhouse.
The engine is a billet construction including the block and head using components made for the V8 engine making the final product very unique. The Flat-4 replaces the 3.5 liter and uses a compound turbocharger arrangement that includes a precision 88mm turbocharger that feeds the larger 106mm turbocharger. This interesting arrangement allows the smaller turbocharger to spin rapidly at lower revs and then feeds the larger turbo to run at higher RPM.
The end product is a reliable air-cooled flat-4 that produces 2029 horsepower on the dyno and is ready to set records on the drag strip. To support the impressive custom engine, this drag racer uses a number of parts from FuelTech USA including FT600, FTSPARK, Peak & Hold, WB-O2 Nano, EGT-8 & FT Injector.
