I'm basing it on years of our collective tracking experiences with the 335I. We've all tried everything, but 1,600F recycled exhaust gas temps is ultimately impossible to beat. The only guys truly able to go lap after lap use methanol.

Significantly stronger than the N55? YES. Than the N54? Not a chance! Like OP stated, our stock block is currently holding daily driven 770whp. Call me when we see this with the S55. Oh, and how bout them S55 rods? Don't think those are as re-enforced as the N54
