If you are looking for a high-quality, turn-key, twin-turbo LS V8 engine that produces over 1,500 horsepower, there’s really only one place you can turn to: Nelson Racing Engines.
Tom Nelson and his company have been developing and building extremely high-horsepower V8 engines using the General Motors Small Block design since the late 1990s. NRE engines are frequently found in expensive resto-mod builds, but its motors have also powered sand rails, Bonneville racers, and drag cars.
NRE recently received a different kind of request that challenged even its expert designers and fabricators, though. A customer approached the company about building an engine for his river race boat, which is only allowed to have a maximum displacement of 260 cubic inches if it is turbocharged, per series rules,
NRE, therefore, had to build an extremely powerful, twin-turbo LS V8 based engine with a maximum displacement of just 4.2 liters. Furthermore, the motor had to be able to run at wide-open throttle for five minutes straight without overheating or failing. Talk about a tall order.
Not surprisingly, the company was able to pull it off. It recently uploaded a video to its YouTube channel showing off the unique twin-turbo LS V8 engine, which is an all-new design for the company, and documenting its first-ever 5-minute dyno pull. It’s almost hard to watch Tom Nelson whale on this masterpiece of an engine for five minutes straight, but on the other hand, this is exactly what it was designed to do.
More information on this engine is expected to be released by NRE in the coming weeks. For now, you can watch the company put it through its paces in the video embedded above.
