AFE Issues...

First Post...Hey friends, I need some insight...
I have an 08 F350 with the 6.4 and it was equipped with the Edge Racing Evolution, MBRP DPF delete, and the Stage 2 AFE intake setup with the pre-filter sock and the 5 layer filter. The filter and sock were both dirty and I had no cleaning kit and am the type to have a spare filter handy so I went to order one up, long story short, I was informed that this intake was an inferior "Early developed" setup and that being as it was in stock and available, I could buy the better Stage 2 SI setup, this intake has the Proguard & filter with sock on it. I bought it and had it thrown in with only minor issues. I went for a spin to be certain there would be no codes or issuses. Once the truck was up to temp, I did a good hard run with it and was disappointed to find my EGTs are nearly 200 degrees higher at WOT than they were with the old dirty "inferior" intake..... I am confused... any of you fine folks have any light to shed?
Thank You

Hopefully someone with more knowledge than me will chime in here but my guess is that your increased egts are from a leaner fuel mixture. I know that the egts get hotter with the increased HP tunes and my understanding is that the higher HP tunes have leaner mixtures.

The part that really confuses me in this, is that the only piece of the equation that actually changed resulting in the increased egt's, was the air kit, from the Stage 2 to the Stage 2 SI... You are spot on about the hotter tunes resulting in higher egt numbers. I am new to the Powerstroke world, but have fairly considerable experience in the Cummins land... the air kit on that unit sure had a lot more space to fit in...lol

new filter is probably filtering the air better, in turn feeding you less air. Less air/ more heat, higher egts... you wanna test it, do a run with the air filter and with NO air filter. Exatcly the same distance, wot, check egts at the end of both runs, shouldnt change at all for a good air filter

My confusion is in the fact that the dirty (less flow) old filter setup, has higher EGT than the brand new and clean (high flow) filter setup.... the only thing that has really changed from one kit to the other that may affect the egt's would be the coupler setup that goes onto the inlet on the turbo, it has an internal bevel that "funnels air into the turbo for improved volumetric efficiency for maximum performance" Not sure...

If you search the past threads a couple of people have posted about sucking in the filter minder with the si intake. Tells me it really does not flow as well as the older design. In the diesel world things are opposite of a gas job more fuel equals higher egts until u get so over fueled you are putting out the fire. If you don't have enogh air it will get hotter.

What ever you do do not take the filter off and do a test run that is stupid these engines suck so much air you will clean the engine bay out lol and the road. And all that dirt will be in your engine and turbo.
