Raising The Redline On The Z

Going dry sump and custom crank seems like a lot without recorded failures to justify it. I understand precautions but innovation often trumps throwing money at something. If the stock crank can handle 8500, and you have a pump to handle 8500, and if their is a valve-train issue and it is addressed to handle 8500, why throw $8-$10k more at the engine when it can be better spent on the consumables you will need to purchase when racing? Rod bolts and better mains would be a good investment as the strain will be there, and it's cheap insurance in my opinion.

Suckerpunch alone claims their pump set-up is race proven up to 8600.
