[WEC] LMP1 where do we go from here?

[YZFrider]

After reading the tech article in the Caddie V8 its clear isn't a stock block. The article said they used a special cast..in other words they melted it down. Oh sure it keeps the same dimensions and bore spacing (so it can pass for stock) but if I had to guess, the cooling passages and the rigidity of the block is strenghthened for higher outputs. A billet crankshaft? Both those modifications I have heard of in drag racing and only the big money teams can afford. Indeed not the same block shared in the road car. And as the BoP changes suggest the motor was likely in the 650-700 horsepower region at the beginning of the season.
