Airflow does go over the top of the engine with the weatherstripping removed....and that itself is the problem. You want that air going OVER the Turbo housing as God and DC intended!

I have a problem with the statement below from the "Stockum tests it was done with real test equipment" article:

"Feel the hot air? ... That is just from convection, the hot air rises and pulls cool air into the engine bay from the bottom, just the way we want it. On the highway, the air rushes out! I am going to do two things."

This does NOT happen at highway speeds, or at any speed at all.
Massive amounts of air come through the huge frontal area front of the PT via the radiator opening and flows through the engine compartment and OVER the turbo housing - cooling it.

I can see the curb appeal of "Hey!, lookit all the air comin' outta my hood where those dopes at DC put that silly weatherstripping!"

The engineers at Chrysler can be counted on as job 1 to hook up REAL TEST EQUIPMENT - I mean the real thing - to test those Turbo temps.
I guarantee you the weatherstripping removal is not a good idea.

It must remain in place to direct the air OVER those HOT engine components - THE TURBO! - and cool that mother down.

The air flows into the engine, over and around the engine, and over the top and over the Turbo housing. I sure don't want a lack of air killing my Turbo housing just because the weatherstripping removal seemed like a sexy mod that must be done.

Not arguing, educating based on experience and design engineering principles.

Cheers and happy motoring![^]
