So do you think there is any added performance gained from a hood scoop? Something kinda like this.

Water fording maybe? I don't know though
-
if you have a cone filter and a shield around it so the intake takes it's air thru the scoop you will make some HP - as an example 20F intake air temp difference results in 5 HP loss or gain depends how you look at it.
-
Well the reason for that scoop is because it's diesel and has a snorkel that attaches to it. There will probably be a few HP gain since diesels tend to run hot and those Jeeps are deployed in Egypt and other hot climate areas but that's not really what it's for.
-
It would seem that it would allow more air in to the air box. I put on the stock TJ air tube. The inlet is about the same spot as the JK. Not sure it would be worth building a scoop. As Sharp mentioned a box inside the hood would also need to be built.

Building a shield/box would help seal off the engine compartment from the scoop and you get better flow with the positive pressure. Otherwise, the scoop is just going to be a vent.
If you really wanted to keep all of the air cool then I would probably go back to using the YJ routing which is shorter and you're going over the engine. Then using heat shielding over everything.

With the motor moved forward 4 inches the stock YJ air box set up was replaced with a Rock-it city tube. Then after messing around with the K&N I swtiched to the TJ setup. I couldn't figure out how to get the stock YJ airbox to work without a lot of work.
I don't mind the TJ setup. I still have the trumpet on. Not sure I am going to mess around with it.

You could use a new elbow that's 4" shorter on a YJ box?
The other problem I see is if you ford any deep water, that's going to get sucked right in as the water pushes over the hood.

:confused: could be. I don't think I have the stock box anymore.
Good point on the water crossing. Not that I have that around here but you never know. I would like to do Fordyce some day.

is everyone forgetting the most important part? IT LOOKS AMAZING! :roflol:
