They have a B18C (of course the JG series) and it was making 769 bhp and 525 ft lbs. They state: "This was accomplished with 22 PSI of boost at 7,000 feet above sea level". I sure wish they would list more details, anyone own one of these motors? I'm curious on what all is done and what turbo is being used.

That was supposed to have been performed on an engine dyno, at a trade show in Vegas I think. There were many doubters on those results...

 

Where and why is there a dyno at 7000 feet above sea level?

 

That's about 650 whp...assuming 15% loss. A big turbo and big nitrous pro drag racer style'll do it.
