In a message dated 96-09-01 03:12:43 EDT, you write: << Maybe you should factor in: a) How Germans drive b) Steep Austrian and Swiss mountain passes. Whatever _we_ think - the inadequacy of vacuum resources in a turbo car is the reason _Audi_ give for their decision. >> You are missing this phil.... In a big way.... As soon as you lift the throttle on a turbo car you have vacuum..... Any countryman anywhere that can argue to me that there is a must for braking UNDER BOOST conditions misses the whole concept of vaccuum vs hydraulic braking systems.... Look at the current crop of BMW, in fact go back to 1986, ALL of them are hydraulic systems, not a one with a turbo.... The engineering of hydraulic vs vacuum doesn't help either argument above, define a) vs the US of A, and our friends in the rockies, even the appalachians, just might take exception to b)..... Think about this a while, your argument makes no sense at all... Plenty of turbo cars are here as well as your side of the pond that use vacuum, not pentosin for braking power..... Don't remember reading anywhere that american cars could not be sold across the pond cuz of vacuum vs hydraulic braking..... Have you? Jump to race car theory, and there is NO proof to support your case either.... Turbo cars running vacuum don't retrofit to hydraulic cuz of safety, or cuz they brake and run boost.... It simply is two different design philosophies phil, vacuum as a general rule is majorly lower in maintenance, hydraulic prolly a better design principle, but very high maintenance costs..... There is no pump in a vacuum system, it's the motor and pressure hoses are carrying vacuum not 2200psi.... Simple low maintenance, lasts the life of the pump (save maybe a diaphram rip) ... Hardly the case for hydraulic brakes.... Don't make the argument any more complicated than it is, it's a philosophy that has NOTHING to do with turbos.... Please do correct me with audi documentation..... Scott
