Anybody try anything like this?

Sorry Techy , but that's a big .. :thumbdn: ..from me.

You need a scoop that is both functional and self explanatory... Like the AMC Scrambler! :bgwo:

I'm kinda partial to the shaker scoop myself!

Allright, you got me thinking back to my MOPAR days. The reason I was thinking cowl INDUCDTION, was I did not want a forward facing scoop to grab snow during the season. But there was a MOPAR design that allowed the driver to activate the ram air scoop from inside the cabin:

I think I will investigate this a bit further. It would be sick to have a scoop on the dragon that has teeth and harkens back to my old muscle at the same time. You cant beat the "fliying tiger" inspired teeth design on this scoop, IMHO.
Best,
OK, back to the scoop. There are generally three very different effects that are considered desirable that involve piercing the hood for a scoop:
1. Forced air systems - this involves supercharging or otherwise inducing higher air pressures in an intake plenum - the engine compensates by increasing fuel producing more "pounds" of pressure which boosts engine performance. Just about any opening to the outside can improve performance as the SC itself pulls in air mechanically (why most go to a cold air intake system that vents to the fender hole in the VX). If you can get the opening right in the air flow you maximize the cooling effect (see number 2).
2. Ram air systems - this works if the opening to the outside is placed somewhere so that when the vehicle is in motion the force of air movement increases the pressue in the intake, thus producing slightly higher pressures and you get a performance gain. Unfortunately, if you map the airflow across the hood the leading edge forces air over the hood about 6-8 inches before it dives back in right at the leading edge of the window. What that means is that for an induction scoop to be effective, it would need to hit the air starting about 6 inches above the hood, a three inch opening would extend 9 inches above the hood or so (this all depends on where you're mapping the air as it forms a large-radius curve so the height varies). This is actually fairly typical and why you see supercharged street rods with the huge scoop extending to the roofline or above to get the most benefit (relates back to number 1).
3. Inducted air systems - basically a hole that lets in outside air (cooler than whats under the hood). If you really look at the scoop on the scoobies it doesn't go to the intake and most other low-profile scoops you see actually go to an intercooler (it's really pulling "exterior air" without a ram-air effect - it vents to the outside to take advantage of slightly cooler outside air temps). If the openings are to the back of the hood, vehicle motion can induce a cooling effect that exits heated air through the openings (sometimes called reducted or something like that). It really takes a bit more than that to get a measurable difference but that's a starting point (to be most effective airflow would be engineered using baffles, etc to direct the air over the motor so it would exit through these venting ports).
So in summary, for a supercharged VX a CAI setup to the fender seems to be optimal (so no scoop needed) - for maximum effect a huge scoop that extends above the air-foil into moving air would be needed as the hood opening. For Ram-air on the VX, the leading edge of the hood is about the only surface where an opening could be made that would actually induce a ram-air effect - you'd have to go to the front of the truck itself for more benefit when in motion (hardly any benefit when not moving). For inducted air, just about any exterior opening would suffice, but since the VX doesn't have an intercoolor it doesn't have much effect - creating openings in the back of the hood would help to pull heat from the engine compartment, but then you're just pulling it into the cabin due to the placment of venting (raises cabin temps and pulls in nasty engine smells).
So forward facing, low profile scoops on the VX are really mostly for looks. Even cutting open the hood would have little cooling benefit (and it could actually be detrimental by dumping solids in the air on the block - think about running water over the engine while it's running (if you're using an unshielded cone filter you can get it in the intake), water in the alternator, etc.
and that's the scoop.

wow John! good input!
That's a very personal question, isn't it?! :laughing:Quote:

What you need is to get that forced in air to the intake (whatever option you use - CAI, airbox, etc). Getting the air there before it is warmed is ideal.
A forward scoop with a hole in the hood has 2 uses a few uses:
- lets cooler, fresher air in at speed.... but this new air is basically useless to you (must be captured and directed to the right area)
- well, it looks kinda neat, right? :cool:
- lets rodents have an access route for finding warm places in the winter :p
What I find ideal is, getting the air to where it is most useful and ALSO being able to pull the warm air from the engine bay in general. I am unsure that we get enough flow over the hood at speed to have a fruitful "draw" of air to be pulled from some sort of insert extraction. This is the mud hole I sit in now. I am considering pulling off the OEM skid plating below the engine bay to promote more flow, but it may not be enough to even bother with. Then, looking at cowl options, whether they be insert related or actual hood modifications.
God! Dont you just love projects?! :cool:

I think it may be something that would grab some of that leading edge air and wouldn't have the "scoop on a scoop" look, but I don't think I would do that to mine either.
Snowtrooper - I also see that you too enjoy Mopars! I've had the same thought and actually my little sketch was thinking along those lines. I have a Lemontwist/Velvet black, 383HiPro, 70RR with Airgrabber, but sadly it's still one of those projects that's in pieces and under a tarp (SOME DAY).
for the new part was to replace the stock panels
that look crummy over age, and make paintable..
and the scoop was just for looks anyway.
I dont see any way to really put a scoop forward enough
to make any difference facing forward or even reversed.
Why not make the Vx look better if it can and doesnt cost
alot of $.
At the very least if you opened it up underneath you could
get some cool and hot air out of the opening either while
driving or after its parked.
Leaning towards this scoop or the Sti style still.
YEs that scoop looks very good though.Quote:

Hey guys there's something that always wonder in my mind .... :rolleyes:
If you mod the hood to add a functional scoop to the intake how do you avoid water getting into the intake ?
Sorry,it sounds dummy & i do admited :confused:
If all goes well, Im going to have a complete new
hood panel with the scoop molded in, so its essentially
a one pcs design.
Maybe by Oct.
I can get the scoops all day long but they have to be
modded some to correctly bolt on the stock panel.
Again, Im more concerned about looks more then anything else.
So ...the blank Hood insert I offered you~~ is no longer required?
Just trying to keep track?
Ya wanted it...then ya didnt....or Don't...?

If bolting on a scoops works just as well even
then the project may get scrapped..
but thanks, Ill be in touch about your panel.
