Idea for custom cowl induction hood

I was curious in finding what options there were for my truck in hood selection. I've never been a big fan of scoops on a truck unless its for a usable reason.

That's why Ive always liked induction cowls. So seeing the lack of them available that look good. So I played with some pictures in paint with my hood and a collage picture i had from the internet.

Any suggestions are welcome.

Idea for a custom cowl induction hood.

Here's one I have no information on but got me thinking. I believe it is a 2nd gen pickup hood.



And heres what I did in paint for how I would like it to be seen. I don't like straight up and down sides I would like to do a slanted side so it looks more like the pickups hood came that way and was molded in. Thus the center could be only 2" high off the center of the hood, and would ultimately cover up the current center bump of the hood.



Then on my truck for a mock up of how I see it. The only thing I'm not good enough at showing is the side you see by the hood. there I would bring the top part past the hood over the vent louvre and curve it back to the hood gradually where the angle piece meets the hood, as it shows on the bottom picture. it's a side view of the hood in the top picture.

Somebody already makes that type of hood for Toyota trucks. I think they are located in Texas but I am not sure. I saw their ads on one of the Toyota truck WEB sites; you will have to search.

why do you want it so big?

This thread has a few more options and ideas...including that blue hood with the big cowl.

Trying to make one with sheet metal would be very difficult as it would be hard to make the bodywork straight.

There are lots of pre fabbed options out there that you just weld/adhesive/bubble gum into place.

If you cut the rear cowl section out you get rid of engine heat. If you put a V8 engine in, it gives the engine bay more clearane on top. I myself have a Louvered hood which gets rid of engine heat.

to supplement what suncomb said, it takes the turbulance and pressure built up against the windshield and forces some of the air through the cowel. Air goes into the engine bay through the cowl, not heat coming out of it. Mine cools my intercooler as well. Take a looks at the link in my above post for pics. They can also be set up as an air intake so it becomes a forced cold air intake.

I wonder if you could use one of these to clear a 3.4 without a body lift? Anyone know?

I wasn't aware that you needed a body lift to clear a 5VZ. 1UZ yes.

The real usable purpose of the idea for me is because I'm planning a LS1 swap into my pickup, but The intake runners on the LS1 are way high. I don't really want to do a Body Lift (I know I have one on right now, but it will be removed when I put on the Suspension lift I bought, Never liked the view of my frame under the body.)

From my research that I've done on it I've I choose the no body lift route I will experience an increase in underhood temps and especially in the Transmission tunnel. Thus the reverse pressure of the cowl induction hood would help alliviate some of this condition.

Also I have searched countlessly for one similar to the blue hood I posted and just cant seem to pin one down, and the ones I did find were all 90 degree sides and too parallel all the way back. then someone else in one of the various hood scoop threads placed a "Stick On" cowl to theirs and I don't like how it fits with the current hood lines as it is.



I know it really comes down to personal opinion.

Obviously the size of how wide the cowl is drawn is a challenge. The hard part I see with molding it into the hood is on the front section where it meets up with the curvature of the current hood lines.

I'm pretty sure you need at least 1 inch body lift to clear the 3.4's intake? Maybe I'm wrong?

some have made it work without a body lift just by cutting the braces under the hood.
