I've been looking over warmonger's excellent excel spreadsheet files. I've got a few questions about the charge compression sheet...
How can turbo'd cars get away with such insane amounts of boost on pump gas? For instance a stock VW 1.8T runs 0.8bar of boost with a 9.6:1 CR. That would make the effective CR 17.28:1, well into deto land. On top of that a common mod is to add a MBC and run 22-24psi. How is that possible on 93 octane? Are the motors soo overbuilt that they can just take the deto?
They also sell upgrade kits with a larger turbo to run 350+ HP all out of that little 1.8t, all on pump gas.
I've also read about the turbo dodge guys running 34psi on pump gas with a CR of 8:1. WTF?
School me wise turbo gurus.
