SAE Article on the 2019 LT5 Engine for the ZR1
Short, but interesting article on the 755 HP ZR1 engine. Great 3D graphic of the engine. I tried to upload it, but it's 16 MB. If you open it from the article, zoom in on it.... the detail is amazing.
A couple quotes from the article:
Quote:
When two muffler valves - one passive and one electronically controlled - open in the more aggressive driving modes, an 800-deg stream of exhaust trails the ZR1 with visible flames in low light conditions.
Quote:
During high-speed testing on the German autobahn, engineers consumed an 18.5-gallon tank of fuel in 15 minutes of flat-out running.
