EGR Delete-Pass Emission with tune?

[scotts99snake]

Hey guys. I am considering deleting the egr in my cobra. I am wondering if I have the egr tuned off if it will pass emission inspection in NY state.

We can get them through inspection without it but its not easy. I would ask why you want to remove EGR it is not the smartest thing to due from a heat standpoint.

Almost everyone with KB's doesn't seem to have it anymore, less clutter in the engine bay. We do not have visual inspection up this way. Just has to pass NYS OBD II testing.

As Dave said, the KB came without the bracket for all the egr stuff. While looking for it we noticed most guys have done the egr delete. It makes it look tons better.

the down side is it hurts gas milage without it as well as combustion temps during cruise....it makes em hotter, thus more heat soak etc.

I am not worried about gas mileage. I will be lucky to see 3,000 a year. Is it a huge difference in combustion temperature? At WOT, there is not difference though is there? Isn't the egr valve closed then?

What are you usually doing before WOT? Lets say on a typical "spirited" drive.....your cruising in 4th gear or even 5th 6th, you down shift and hammer it. Not saying your going to eat a motor without it, but it does have a beneficial function. Remember your pistons other purpose is to act as a heat sink, and dissipate the combustion heat.

For a motor that almost every termy owner is looking to keep healthy and cool (via cooling mods, heat x-changers etc) this is just another. The newer vehicles DONT have an actual EGR valve anymore. EGR function is controlled via the VCT (variable cam timing).
