- Griffin Steinfeld
Welcome to hand-built horsepower for the obsessed. At Griffin Performance, we build high-performance marine engines for the drivers who refuse to lose whether you're chasing a win light or leading the pack to the sandbar. Our turbocharged, supercharged, or naturally aspirated monsters built to outperform, outlast and outshine.
TURBOCHARGED ENGINES
Reliable turbocharged engines that are proven under pressure. From our 800hp Ls's all the way to 4,500+ horsepower billet Hemi's, every engine is built with precision, attention to detail, and the mindset that it needs to survive wide-open throttle without flinching. Reliability isn’t optional — it’s the standard.
SUPERCHARGED ENGINES
We build supercharged engines that don’t just make power — they make a statement. From roots to screw to centrifugal setups, every combo is dialed for your exact application, whether you’re cruising for fun or chasing wins on race day, these engines are built to take the hit, live at high RPM, and keep pulling every time you put your foot down.
NATURALLY ASPIRATED
If simplicity is your flavor then naturally aspirated engines are the way to go. Whether you are looking for an LS based high rpm screamer or a big inch big block Chevy we can put a package together to suit your needs every time the key is turned.
