My goodness, this is a beauty and loaded with plenty of horsepower even for those souls who feed on more of everything!
I wonder how those people know how all this fits together to make us all want more and more of such a good thing!! |
''The LT7, the heart of the ZR1. Powered by exhaust gases, turbos are essentially air pumps that jam more air into engine cylinders. Repeat: more air equals more power. One measurement of the amount of air is pressure. Atmospheric air pressure—what we all experience just being on earth—is about 15 pounds per square inch (psi). The LT7 more than doubles that, adding an additional 20 psi. That boost necessitated additional hardware. Redesigned cylinder heads maximize the pressurized airflow, there are stronger connecting rods and pistons, and a pair of intercoolers (essentially, small radiators) chill the air.
''Turbos spin over 100,000 revolutions per minute (rpm) and, like engines themselves, have a redline. The LT7’s sophisticated electronic sensors measure turbo speed and an electronically actuated wastegate bleeds off exhaust flow to run the turbos close to but not over the 135,000-rpm redline. The 1064-hp peak hits at 7000 rpm, 1000 revs short of redline, and at just 3000 rpm, the engine produces 800 pound-feet of torque, which it maintains through 6000 rpm. Juechter promises the LT7 is “docile around town and when you get on it, it’ll change your life.”
