There is no EGR flow into the manifold at idle.Originally posted by the_spy_guy@Jan 19 2004, 06:08 PM
first: the egr is designed to help keep the CYLINDERS COOLER because there is less combustible material.....thus your engine runs better.
second: your egr is shut off automatically at WOT, therefore disabling it all by itself.
the only benefit i can see id disconnecting the vacuum line while at the track to keep the intake cooler while idling, but still not benefiting, because of the afore mentioned stuff.
so unless you don't floor it when you race, this is kinda a worthless mod.
EDIT: needed to run the spell check, and feel free to challenge my small amount of knoledge.
That sounds to me like the opposite of nitrous injection. I mean, the way you make power is with the most power explosion you can safely achieve within the cylinder, and you're not going to be able to do that if you're sucking in inert gas that take the place of vital fuel and oxygen.Forcing some exhaust back into the cylinder slightly reduces the concentration of oxygen and slows the burning a bit[/b]
