Air Ram hood for 2000 XLT SOHC 6 cyl

[410Fortune]

both

But ford put the temp sender in the pan on my trans, maybe it was just easy for them to mount it there? I dont know.

Also that was a type-o, the hottest my 4r70w has been was 150, not 130.

Don't most small hood scoops not even help when traveling at high speeds? I thought, and I could be wrong, that at high speeds, air is traveling too fast or is hitting your bumper/grille and angling up and actually going over the hood scoop if you have an aftermarket one.

Some examples of a good hoodscoop would be the Subaru WRX STi where the scoop is so large, that air cannot go ever, and therefore must go in.
It may be carbon fiber, but it is stil in the same shape as the stock hood and scoop.

Another is the Mitsubishi Lancer Evo VIII (sorry for the rice rockets as examples). This has the reverse hood scoop. I can't go very much into detail about why it works, but if you have ever driven in a convertible at high speeds, the hair on the back of your head will get all messed up because the air goes over the windshield, and then sort of somersaults over your head, then into it, then out the back of the car. The Evo hood scoop works much the same way in that the air rolls over the hood, spins back into the hood scoop and into the engine bay, and then stays there because it has nowhere to go, thus cooling the engine.

The FORD GT 40's hood works much the same way, but their reverse scoops are much more extreme and much more noticable.

How well a hood scoop or ram air will work depends a lot on the aerodynamics of the vehicle, and the type of scoop. If you have a shaker system where the scoop is sealed to the intake, the motor will pull air into the motor through the scoop. On the '03-'04 Mach 1, it has been show in wind tunnel and track tests that raising the shaker 3/4-1" will increase the performance of the vehicle slightly due to the shaker getting more airflow, but it's a slight increase. If I remember correctly, it was about a 2 mph increase at the end of a long straightaway on a road course, but that was at track speeds, not road speeds. At road speeds, the stock height, which has the opening just above the hood level, does increase the performance over not having it there at all. Part of the reason Ford let the designers put the shaker on the Mach 1 was because they proved it improved performance.

What you're talking about with the EVO and other vehicles is called Cowl Induction. It doesn't work because air is being forced in, but because it gives the motor a place to pull cooler air in. The phenomena that you mentioned with convertibles is caused by a low pressure area that is created as air rushes over a lip. Just below the lip, a low pressure zone is created, which in turn tries to pull the airflow back down, creating a turbulent zone. Ideally you want to minimize or eliminate this effect because it creates larger amounts of aerodynamic drag.


The bottom line is that ANY holes in the hood will help drop underhood temperatures, whether it be by forcing air into the engine or engine bay, or allowing hot air to escape.

ray was just putting things in the proper forum and or thread.
Alot of posts and members here guy.

Okily dokily, man. Wasn't sure what the context was, but did sound like a reprimand, so reacted accordingly. Excuse my quick retort.

JDaper is almost right. the way scoops like that on the EVO and GT-40 work is just the same as the example of a convertible there is difference of pressure (inside and outside the engine bay) and the natural tendency of things is to be at equilibrium so the air moves the place where it can reach equilibrium, this is based on Bernoulli principal. and the GT-40 may have something to do with letting air pass over the radiators because if I am not mistaken the rad's are in the front behind the lower portion of the grill.

Help me push this hood, they want too much for development though($3500). Good luck,

I like the truck and IMO lowered trucks look bad but this one looks really good

Sooo, anyone got any ideas as to where I can get a functioning ram hood for my 2000 XLT SOVC 6cyl? I sent an email to the place originally suggested (thanks, spindlecone!), but haven't heard anything. I've seen information somewhere before about a system of duct work built into the hood which would redirect air over the cold air intake, thus eliminating a waste of air over the whole engine compartment. Beyond the argument as to how much this increases HP/performance, I just like the look . It seems, incidentally, that the more I look into mods for my 2000 XLT, the more I find that the given option is "not available for your vehicle" for items one would expect would be easy to find; I mean, really, wasn't/isn't the Explorer the most popular SUV on the planet, or at least, in the US?

Thanks,

Bill

Another place to try is http://www.cervinis.com . They specialize in body kits, hoods, spoilers, etc.

actually, sorry- that one is a shaker, not just a ram air hood.

Still, nice!

And, what's the difference between the "shaker" and a "hood"? Is it that the shaker is cut into the hood, and goes directly to the carb?

Thanks,

Bill

Thats the problem Bill,is no carb in the center of the hood

yeah, all mine is doing is cooling the overall underhood temp. I thought aboutu more- but not useful at all for my application. And with my truly custom cold air intake (not the bolt on that pulls hot turbulent air) i really didn't thin i'd see any gains. My filter is way down in the "crook" of my bumper at about the height of my lug nuts.

shaker isn't part of the hood- just comes through it, mine sort of grew out of that center piece in this picture

Just tried this site, and the ford model choices (for a 2000>Ford>Sport Utility) are the Excursion and Expedition.

i would like a hood too but not for the price, and then having to get it painted too.

I think the bottom line is, what you seek do's not exist for an FI engine
