CC The 455 looks GREAT!
Got the ****** in the Samurai ready for R&R tomorrow with my son's help. Two bolts and the stick removed and it gets pulled and the "new" rebuild goes in along with a fresh cut Flywheel and probably the clutch (Ready to go but is it needed?...)

I spent some time measuring pressure differences over the hood of my car. I'm looking to install some vents in the hood to reduce underhood temps. All test runs were done at 60 mph. The grid is 5" squares and units are in kPa. These are the differences, so the more negative, the better.

Currently leaning toward some of these vents from the '13-'14 Mustang GTs.

Placement would looks something like this:

Removing the cowl seal will improve air flow how? That is a high pressure area and could actually stall air flow through the engine compartment.
In fact, that is exactly what happened on a friend's silver state Firebird with an unsealed cow;l where he intended to use it for air induction to the air cleaner, only he never actually sealed it to the air cleaner. At speed it stalled air flow though the radiator and it overheated. We sealed the cowl to the air cleaner and removed the flow to the engine compartment, and the heating problem went away...
I agree, cutting hood braces isn't good but the question there is what will he do in their place, or does he leave them, cut the skin only and just sacrifice a little of the vent area...
Very nice swap! How does it handle with the big v8?I agree 100%. Removing the cowl seal/raising the rear of the hood, only hinders engine cooling. The windshield is a very high pressure region, second only to the nose.
The hood braces are very tall/deep. I plan to only cut the skin and a small amount of the brace to fit the vents. The first and last sections of the vents don't see any airflow, so I think it will be okay to bury them in the brace.
This project is necessitated by the classic "big engine in a small space" problem. The car was originally equipped with a 2.8L V6. After a while, I got tired of it and installed a 4.2L V8. The longer V8 limits space directly aft of the radiator. Under ordinary driving conditions, cooling is not a problem. Driving hard on a hod day though can cause the temp gauge to rise higher than "normal" though. I've been wanting to do some track time and get back to doing autocross, so I need to make sure cooling is taken care of first.
Not the greatest picture, but you can get an idea of the real estate issue.

Before cutting up the hood have you thought of adding a switch to power cooling fans when wanted/needed?
You could keep a sleeper look to it.

Or go look at an S4 and see how the factory does it.....
I appreciate what he's doing and have no skepticism of his project, nor it's execution.Removing the cowl seal will improve air flow how? That is a high pressure area and could actually stall air flow through the engine compartment.
