removing water from EGR Space WHY????

In all of the pictures I have noticed everyone has removed the hoses going to the EGR Spacer.

Is there a reason?

I thought the perpose of the water to flow through there was to cool it down.....

The water is coming from the heater rail, so it is very warm. We remove it because you do not want a boosted engine that is already pushing very hot air to go through the spacer - this will just heat it up even more.

It was used by Ford to warm the engine quickly on a cool day.

Really you should never bypass the coolant lines to the TB spacer unless the EGR is bypassed also. The EGR puts hot exaust through the intake while the car is crusing, Ford put the coolant through the TB spacer not only so the car runs better in the cold but to cool down the temprature when the EGR is open and recycling exaust for lower emissions. If you have to pass a smog test that could be a problem if not bypass them both and keep your intake temprature down. I am going to bypass them both just every two years I will have to hook it back up as well as the factory H-Pipe w/ converters.

AMEN.

Jason is correct. This issue was well documented in Super Ford years ago in an article on "5.0 Myths"and their conclusion was to leave it connected unless your EGR was disconnected.

can you just unhook the sensor that plugs into the egr? or do you have get a speacial spacer without the egr hole in it? what is the best way to bypass the egr?

when you bypass it you still leave the sensor plugged in, You can by the little plates that replace the egr, but I'm not sure how these work as far as just taking the sensor off, and fitment of the intake tubing afterwards. Maybe someone else will chime in here.

So what your saying is just leave the EGR and just disconnect the water lines from the EGR spacer and the heater rail?

no we are saying do NOT bypass the water around the egr spacer unless your egr system is disconected

The Cobra intake has the EGR with no water running around it and in the old carb days the water was to help cold start which is the purpose on the 5.0 also not for cooling the EGR. I always removed the water line so that I would not end up with a water leak and sending anti-freeze into the intake.

wrong... many magazines have tested it and intake temps went way up after bypassing the spacer

Like I said before in most of the pictures I look at the EGR is still connected and the water lines are no longer going in the EGR spacer.

So whats the answer...

If you are still using the EGR don't disconnect the water lines?

yes mheinjr
you've got it :)

water temp < exaust gas temp

Now you have me wondering if I should hook mine back up!!!

I think I threw out the fitting from the lower intake.

Never throw away parts you think you wont need again!!!!

I will always run my hoses when there is an EGR in place. It doesn't gain anything to remove those lines and it does help keep the EGR spacer cool.

I can assure you that exhaust gasses passing through the EGR spacer are hotter than 180*s of water temp. Just my .02

Guy's if the tube that comes back up from your h-pipe isn't hooked up the egr will not function.

not nessecarily
otherwise id have never passed emmissions in TX, theres no way my car runs clean enough off EGR to do that

im certain there is a way to retain that and ditch the smog pump
ill write up a how to on in after i do it sometime this weekend
