Anyone Disabled EGR on a V6?

[DannyC]

I hadn't thought of this for better performance but it does make sense. Has anyone found a simple way of disabling it yet? Maybe just taking the vacume hose off?

[tlrche]

if i knew what it did... i could give input

[DannyC]

EGR=Exhaust Gas Recirculation Valve. It takes exhaust gas from exhaust manifold and recirculates it back into the Intake manifold. Not really the best for high performance.

it is an electric solenoid, so unplugging it would cause a code for sure.

[DannyC]

hmmmm didn't realize that. I was thinking old school where they had a vacume line :D

On the LH cars to disable the EGR we cut the piping and slapped on some vaccum caps and hose clamps on the EGR and intake plenum. We left the EGR on so we wouldn't get a CEL but in all it was disabled.

Unfortunately with our cars we cant cap the EGR, i know i tried, since we use a MAP sensor and from reading the service manual the computer looks for differences in vacuum from the MAP sensor when the EGR electronically opens up, if it does not detect the difference in vacuum when the computer says the valve is open it will set off a code.

Darn these computers for spoiling our mods.

How about a EGR simulator?

if someone can build a simulator, then you may beable to do something basic like install a plate. thats something i know that was done with the cars i came from modding.

maybe a place like www.casperselectronics.com can fab up something or already have something??? i havent been there in a while, but they had many parts for GM dealing with the same.

What I was thinking is cut the tube going to the exhaust, leave the side open to the EGR(may need a filter of some kind) but seal the exhaust side so you don't have an exhaust leak or just plug it. That way the egr will still function but pump fresh air in instead of exhaust.

Will this work?

It makes perfect sense to disable an emissions device and void a warranty to gain 2 horsepower...

never said i was going to do it, just mentioning ways i've seen it done with other cars.

you do have a very valid point though...although people will do whatever with their cars...

I don't see why not as long as it's something reversable.

This is similar to what I did in my Hyundai but to the Throttle Body. It was a throttle body coolant bypass. Coolant used to run through the throttle body to supposedly keep the plate from freezing shut under cold weather conditions. so it heated up the TB thus heating the air. We just re-routed it so that no coolant goes through.

ah the coolant TB dealies... i remember they had those on the v6 cavaliers back in the 88-93 setups.

i think hes more looking at it cost vs gains perspective more so...

think about it. a plate to block it, and gasket probably10-20$ then once someone makes a device to plug in that does a sim job...about 35-50$ so about 70$ for a gain that really wont be felt or useful...

for some that wouldnt be worth it. for others it might be.

Yeah, on my 97 Intrepid 3.5, all you had to do was slip a vacume cap onto the
bung. It stopped any vacume from being drawn through the EGR, and it did allow for very noticeable performance gain in the way of throttle crispness. Fuel economy went down a bit though. I also had one for the pcv valve. The 3.5 plenum had a valve that basically altered the plenum length, and you could set it so the plenum was more open at initial throttle input. Fun.
