In San Diego, California, Tee Aardsma and Kevin Braun make race engines that are one of a kind. Their newest car is a 6.0-liter V12 that will break speed records on land. Aardsma Braun hasn’t said how much power the land speed racer has yet, but it was just dynode, and the hand-built V12 sounds crazy. Before making the block and cylinder heads, Braun got used to NASCAR and IndyCar engines, took them apart, and looked at how they were made and worked. Then, he used 3D printing to make plans for the new race engine. Even old race technology works fine with their V12, which Braun and Aardsma admit is probably years behind what NASCAR and IndyCar are doing now. After each part was made by hand, a unique crankshaft and pistons were made for it. Aardsma and Braun say the naturally aspirated V12 would spin up to 12,000 rpm and produce 750-800 peak horsepower. The results of the dyno will be made public in the future. The Aardsma Braun V12 sounds solid and unique on the dyno. Its deep, burbling sound sounds like a NASCAR V8, but it idles pretty high. Even though the engine isn’t as high-pitched as the small-displacement V6, it makes the same high-rpm wail as IndyCar engines because it goes faster than a NASCAR engine. Even though it doesn’t have the unique sound of the GMA T.50’s Cosworth 12,000 rpm V12, it sounds great. This engine looks like it is connected to a sequential manual gearbox. It is housed in a unique tubular frame chassis with a long wheelbase. Aardsma Braun says nothing about the engine besides its size and expected power. Cal Rother will drive this rocket with a V12 engine in the first 2023 Bonneville Speed Week race on May 20 at California’s El Mirage Lakebed.
