i really appreciate your fabricating skills, looks like a great job!
i'm a big fan of hood scoops and louvers, great way to get heat out of the engine bay...

there is a perfect spot under the drivers feet for another hidden storage bin but to do so i had to relocate the suspension seat back 2" to clear the lid. this nessesitated a longer seat track.
i took a seat track from an old seat and measured, cut and installed the longer teeth track. this will allow ample seat movement for shorter or longer drivers. the storage bin will be shallow (6" deep and roughly 9" wide and 12" long) but as most know, the more storage in a 40 the better.
i will take pics of the rear hidden storage bin later it is the size of a normal aux fuel tank with a flush mount water tight lid. 29" long, 16" deep and 16" wide for storage of ropes, clevess, etc etc.
the 4 tuffy boxes, dash locking storage, hidden rear storage and hidden drivers floor storage as well as the glove box... there is not much wasted space.
thanks for following along.

Drive a Landruiser, enjoy life
I wish I had a project like yours. Must be a good feeling to see things coming together, knowing that much of the fabrication was done by yourself. Great stuff to read.

thanks Ron, it is a nice feeling.
i am excited when i design the truck in my head
i am excited when i tear the old donor down
i am excited when i fabricate
i am excited when i am fitting the fiberglass parts together
i am fearful when doing any mods to the elec harness
i get burnt just before the paint process and am thankful the painting is sub'd out
i get excited when reassembling all the parts back into a functioning truck
i experience trepedation when the customer first lays eyes on his "new" truck. i try to do the best i can when i am building the truck but sometimes i wonder if my best is going to be good enough.
if he likes it then i am overjoyed / extatic and a wave of relief flows over me.
if there is an issue then i fix the issue but the feeling is diminished.
there is a couple stages where you are overwhelmed with exhaustion.
there are a few sleepless nights where you are trying to figure how to make some idea work.
all in all, this has been a fun build.
maybe i will post up my privious build for a customer in Long Island NY.
this is a pic of his finished full fiberglass 40.

Wayne, before you cut that hood, it might be worth while to put some tell tails on there and go for a drive. (not this truck, obviously) I have found the 40 aerodynamics to be a strange beast. In other words, the scoop being that far back, there may be a pocket of turbulence coming off the windshield and you may get very little forced air flow at that point.
You could easily make some tails, or tales depending on who you ask, by taking some sheet magnet and gluing a ribbon on top. This way you can move the magnets around to different places to see where the cleanest air is. Tell Tales on Flickr - Photo Sharing!

LOL!
my brother made the same suggestion yesterday. he was mentioning the near verticle windshield will affect the air flow location. he was suggesting that the best MIGHT be right at the base of the windshield...
now all i need it so find someone in the area where i can install some tales onto their hood.
i would rather keep it away from the front edge due to the length of the plenium needed to reach the Intercooler but it will have to be reasonable.
thanks for the suggestion Rutbeer

Wayne,
Your project is really looking great. Thanks for the detail. I will be reviewing this all over the next month and am going to be after you with a pile of questions as this is now packed up and on a boat due to arrive in about a month.
It'll be going into the 40 a week after it gets here. Again thanks for all of the advice and the inspiration.

Eh...I'll do it. I have nothing but time at the moment. I think it will be fun. It will be nearly impossible to photograph, but we'll see how it goes.
Nice work Wayne.
I have also wondered about this top-mounted inter-cooler..
If the cooler lays flat on top of the engine with a scoop in the hood, wich way through it do you intend the air to flow ? Seems to me that it's most likey to flow from the enginebay and up through the scoop rather than forcing the air into the scoop and out underneath... Then all the air will have gone through the radiator first ! ? At high speeds maybe it will flow the other way but at low speed the fans will certainly push air out the scoop, as far as i can see..
Sure it wont be an interwarmer rather than intercooler ?

the design of the scoop wil force air downward even at slow speeds.
you also have to remember that the charge is not heated till the boost comes on. if you are idling around the city then the turbo is creating little or no boost and the charge will be the same temp as if there was no turbo or intercooler.
the intercooler is roughly 2" above the engine so you have airflow down through the engine compartment instead of being trapped against the block.
this system works well on my PZ and that is why i move that idea over to the HZ design...

Sound like you have thought things through.. Keep up the nice work..
aero update
Very scientific testing here.
Summary:
Aero tested in front of hook hooks, behind hood hooks, and at about 4" from hood to cowl split.
In front of hooks: Scoop must be forward facing. Tales seem to be in clean air, at least up to 50mph.
Behind hooks: Tales move from moving towards windshield at 0-30, straight up from 30-45, then all over at high speeds. This location is not recommended.
At cowl and hood split: Scoop must be rear facing and is clean from 0-50mph. Best location tested....looks like your brother was correct.
No tests done beyond ~50mph....no real wind or traffic to screw it up.
