EGR Valve

[Toadz]

performance purposes

If anything, you'll lose performance.

Wrong person to call a hippy..

I think it is....EGR puts hot air into your intake so i think deleting it would be a gain

It actually helps lower combustion temperatures and lowers fuel consumption while cruising. During idle and WOT it's not in use.

so what your saying is everyone that has deleted EGR needs to put it back on because it will perform better?

The way it was explained to me, is that the exhaust it recirculates is still a lot colder then the combustion chamber so it helps CRUISING. Like stated before idle/WOT are not affected so 'performance' no...economy yes

how much of a gain are with talking, like 1-2 miles per gallon, or something so small that it aint worth my money and time.

just unplug it and see what ur mileage does..if u dont like it hook it back up

you know what, thats not a bad idea.

good ideas are all i have

But your engine is HIGHLY inefficient. So that exhaust still has gas in it, so technically you're forcing more gas into the engine then just the injectors.


I know it's a dirty system, and removing it keeps the engine cleaner, but it should help gas mileage (whether its 3mpg or .1mpg I do not know)...even if it does hurt performance slightly.

That's not the purpose of EGR. In fact it is the opposite. It introduces the INERT exhaust in order to lower combustion temps. This reduces NOx emissions.

i noticed no difference, with or with out the egr. I took it all off just cause it looks cleaner.

here is some more info, i say just take it all off IMO

should i take off my egr valve? pros and cons? - LS1TECH

EGR VS. NO EGR...Wat are the Pros and Cons? - LS1TECH
