800 horsepower moving a giant fan sounds pretty awesome.
Do you know those boats with giant fans on the back that you usually see in swamps or on frozen lakes? Well, the United States Coast guard uses them to respond to emergencies. And when a vehicle is used by a branch of the US armed forces, it needs a lot of power to handle the job.
That is why the US Coast Guard recently ordered a pair of LT5 Marine AirBoat Engines from Katech Performance. The Michigan-based performance shop is highly renowned for tuning General Motors engines, which is likely why the company was tasked to build a more powerful version of the LT5 crate engine from the military branch.
The LT5, as you may remember, is a 6.2-liter supercharged V8 that produces 755 horsepower and 715 lb-ft of torque in stock form. It was only used in the 2019 Chevrolet Corvette ZR1 yielding a 0-60 mph time of under three seconds but the engine can still be ordered separately as a crate motor.
We are proud to have completed these two Katech LT5 Marine AirBoat Engines for the US Coast Guard," said Katech on its Facebook page. "These engines reach 800 hp on 91 octane [gasoline] and engine data is displayed to the boat operator via a Bosch Motorsport DDU9 integrated with the factory ECU. When it comes to LT5 development, nobody is more ahead in the game than Katech. Stay tuned for more updates, products, and news!"
According to Muscle Cars & Trucks, which first reported the announcement, the Bosch Motorsport DDU9 mentioned by Katech is a programmable dashboard display that is typically used in motorsport applications. It can also be used for military purposes as the Coast Guard will be able to design its own graphics on 12 configurable displays.
We aren't sure how fast an 800-hp fan boat would be, but we'd expect it to be pretty lively. The LT5 is the most powerful crate motor offered by GM and it isn't cheap at $19,995 a pop. Plus, we imagine the Katech tuning added to the price as well. The LT5 V8 uses a 2.65-liter Eaton supercharger and was specially designed so it wouldn't overheat like the LT4 in the Z06.
