RE: E85, more questions

["Dave Dahlgren" <ddahlgren@snet.net>]

Turbos affect air density.. The pressures are not as great as you might
imagine. All those calculators that say you have an effective compression
ratio for a certain amount of boost are horse droppings..
Last I knew the EPA does a driving cycle and I doubt if breaking the speed
limit is part of the cycle so the boost might not be much or very frequent.
