Rick Miley,

I think you should better understand the process of how the EGR valve functions before denouncing the idea on a Turbo. It will work....... Remeber the EGR Valve is still fully fuctioning on this mod.

If you were correct and it would be blowing air out of the "breather filter" then it would also be blowing air out into the exhaust manifold as well, when hooked up in the stock configuration. I don't think the engineers would what to "Create" a manifold leak.

Look at it this way, in order to blow air out the EGR valve and hence out the filter. The intake manifold pressure needs to exceed that of the ambient air pressure 14.7 PSI (sea Level). This may be the case at High RPMS but again at high RPMs the EGR is closed.

To see it another way there is really no such thing as "suction". In an engine the pistons do not really suck air in through the intake, but rather create a partial vacuum in the cylinder and the outside air pressure rushes in to fill the vacuum at 14.7 PSI. Also as valves open and close faster at higher RPM's there is not enough time for all the air to fill the vacume in the cylinder to make 14.7 PSI a turbo or supercharger can help to balance this out, in an over booted engine it can pump in more then 14.7 PSI. Again the EGR valve would most likly be closed.

In aviation most turbos do not over boot an engine, the proccess is termed turbonormolizing, as the air get thinner as you fly higher the turbo creates the same manifold pressure as at sealevel.

Ok I get carried away.....
