The BMW S65 is already a legendary platform--engineered by BMW's dedicated motorsport engineers and engine builders as a high-revving, naturally aspirated V8 with exceptional capability right out of the box.
What separates a VAC-built S65 from the rest isn't potential--it's reliability, longevity, and execution.
The VAC NA S65 476HP Engine Package takes BMW's proven foundation and elevates it through precision machining, engineered clearances, and disciplined assembly practices developed over decades of race-winning experience. The result is a naturally aspirated S65 that delivers repeatable power on pump gas, with the durability required to win races--and keep customers loyal.
VAC engines are winning races in SCCA, NASA, and BMW CCA Club Racing, as well as rally, hill climb, and vintage racing around the world, because they last.
