Default rear hood seal in or out?

Has anyone done any current tests to see if removing the rear hood seal has any advantage in keeping the intake manifold, turbo and PCM cooler? I haven't seen any postings for quite a while concerning this matter.

The final verdict was to keep it in.

Put mine back in and high speed travel is quieter and, for some reason cooler!

I put my seal back in when we had the heavy rains.I noticed that in heavy traffic the temps seemed higher and the performance dropped off as compared with the seal in.I was just curious to see if others had the same results in traffic.Thanks for the input.

The car was designed so that the airflow would go down over the turbo. With the rubber out the airflow goes out where the rubber is missing and does not cool the turbo.

I have my outside temp sensor mounted in my airbox running an Airaid intake. I have also mounted the temp sensor in various places in the engine compartment. I found temps higher when I had the strip out. I think someone else did a similar test and found the same. I put mine back in.

I did some temp tests with it in and out and found no change while moving above 25 or so. I put it back in too.

I think if it ran better with it out.DC wouldn't
put one in.That would be another nickel in their pocket.

I guess I will be learning to live with it "out" after I install my Cowl Induction hood. But then I also have the PTeazer grill & front end going in too.
