Yes, I guess I should have said once you lose vacuum after the first good brake application or power steering application. Point I was trying to make is that EOC is disabling engineered components on your car...and the car's performance will undoubtably suffer. My second point was that the loss in performance at that point is MORE so than a guy running a 6" suspension lift on a chassis that could maybe upsize tires by about 20%. I'm still willing to see a side by side comparo of a lifted truck next to a vacuum depleted EOC truck. If I'm wrong, well than at least we'll have data to go on instead of internet opinion eh?!
First Point is that the lifted truck will be more consistent with braking distances and handling than a car that is in between EOC and 'normal'. So the safety thing was not a good analogy as a lifted truck braking could be compared to an old 60's small car in stopping distance/handling (meaning that the give vehicle has on average a defined expectation of it's performance and that the driver is responsible to understand those limits). A car that has to be monitored based on vacuum pressure, because it is being cycled on/off is another human induced variable (point of failure outside of the car's mechanical properties) so the OP stating that the lifted car is just as unsafe as his EOC technique wasn't a good comparison because it's comparing technique to mechanical limitations. We don't compare the handling/braking characteristics of an 18 wheeler to a Lotus do we?
