Just kidding, it rocks.. But we were just hand over the Corvette ZR1 press book and there is one cool picture for the motor geeks out there. We have already seen the LS9 engine torn apart, but I had not seen that one. you are looking at the ’twin screw’ detail behind the LS9 supercharger.

Those two things push enough air to help the engine maintain power hrough th upper levels of the rm band, which is the area where supercharger tends to diinish.

For the extra geek, GM name those ’heavy-duty and lightweight reciprocating components’!
