The Porsche flat six is a great engine. I didn't know it had seven oil pumps. I wonder why? I would have thrown the Audi 6.0L V12 TDI Diesel in there. I know it's a diesel, but the thing makes 500hp and 740 lb ft of torque. And since it's a diesel that torque is available throughout almost the entire rev range. The thing sounds great as well and still gets 20mpg with all that power.
