We get lots of dark marks on the pavement out here too...
Would sure like to hear as many details on the engine as you want to share.
All I know is that it is a "ZR1" supercharged 427 LS.
Heads ? Cam ? Idle vacuum ? Compression ?
Mods ?
I usually assume that even the modern compression style blowers are still only about 5% efficient (including drive losses), which means at 882 whp the base engine is making 550 to the wheels ?

Huh???!!!!!! I will guarantee it makes way more than 550 rwhp. 5% efficiency seems just a bit low................ I remember when they were first starting the dynoing of the ZR1's their first dyno pulls were making close to 700 rwhp. They definitely backed it down for the production cars.
