Hmm, well we'll see what comes of it cause as soon as the weather dries up it'll be more of a daily driver.

Is it back in the car yet

x2, At 30* ambient it takes almost 30 miles on the highway to heat up and the heater doesn't work very well even when the car is at temp. Not for street cars.

It'* not that bad.
At 40 F ambient it takes about 10 minutes to warm up to 160 F and the heater works just fine.

.....it only takes me 8 minutes to get to work.

I did six months of research and had blocked coolant passages as a test. Temps logged were not any different.

However... I'm modified past using this small coolant flow through the supercharger and into the throttle body. Research has been done with no change in temps that stopped me from pulleying down at that time to a 3.2" pulley (yes..this was the ported charger I had on the car) With my new setup and many other cars (GP'* mostly) running the same setup...I'm confident that there will be no issues.

Keeping the EGR in my emission testing state is a wise move for me. Having a programmer to tune with, the ability is there to use or not use it. I plan on doing more research and testing to vet it out.

Dame..I'd check your thermostat and gaskets. This particular vehicle has never taken anything more than a couple miles to come up to temperature. In your climate, I'd suggest the higher flow of an Intense T stat.

Also in the install is another test. I am going to find out in the first 10 minutes if pre 2000'* (S2'*) need to run a paper thermostat outlet housing gasket. This one is installed w/o it.

Jim... it'* all good buddy. The buca will be chillin for you.

Just FYI ... Going on the assumption that your states emission test is that they plug in to your OBD2 port and do a scan.

The States scanner is scanning your computer for a Error Code in the PCM for the EGR. You can deactivate the Error code from ever coming up, so that the State Emission scanner thinks everything is alright . Unless they do a visual inspection you could get away with it.

They do both. I previously worked for an Emissions testing company in the payroll area and they pay bonus' to the inspectors that find missing emissions equipment. I'll work through the pcm to make it happen (or plug the pipe, cough) if I decide to go that route.

Once it'* up and running, I'll be logging data like mad. Then running other tests etc to see how things react w/o EGR etc.

Hopefully you will find out in your testing what I found out with my testing.

Taking the EGR off reduces the inlet temp from 130 F to 110 F. Blocking off the coolant passages reduces it to 100 F. Baseline 45 F ambient temp. That'* a 3% power increase.

Further testing to see if it is linear as the ambient temp increases, i.e. if ambient is 90 F then inlet temp with all blocked should be 145 F. That'* with the boost bypass open.
Under boost conditions, the temp raises significantly more unless you have other controls.

Your manifold air temps may be lower, but your combustion temps are higher.

I also monitor the exhaust temp coming out of the heads. It has not increased since removing the EGR.
If combustion temps have increased, I haven't noticed any detrimental effects.

If anything it gives me more complete combustion.

You haven't notice more KR than usual at all?
