KR> EGR valve as waste gate

> Thanks for the detailed response. Thank you for thanking me. :-) > the exhaust gas would be intruduced into the inside of the air filter The big problem that jumps out at me is that you are adding mass... The carb doesn't know it isn't reg'ler air. Thus the carb will introduce fuel based on th

Thanks for the detailed response. Let's explore the option of introducing the exhaust gases before or after the carb. On Mon, 2008-12-29 at 22:46 -0800, George Bearden wrote: > It displaces BOTH fuel and air, the mixture, not just oxygen selectively. > Thus the mixture remains almost the same. >

I don't know, But when I read my GM manual, they use it to to cool combustion to reduce NOx emissions, they say it cools the fire enough to change the NOx emissions and is used only at higher throttle settings. They say the exhaust gas is inert and thus displaces (reduces) available oxygen, with

Turbo vw engine engineers: I just read on krnet about a turbo'd vw motor lifting a head at 3600rpm, 36" manifold pressure. My vw motor has the revmaster turbo setup, draw through carb, etc. No wastegate. 20 minutes running time, not yet flown. I once asked a turbo guru once about adding a wast
