This would look tough on any truck.
The New Trans Am Ram Air

http://cgi.ebay.com/ebaymotors/ws/eB...tem=1874279513 This is the scoop only for $125, can put it on anything

I've always had a special place in my heart for the T/A, after all it was my first car and my first love.

 

Thanks!

 

My Hood. Much lighter then stock and gives it a tougher look then stock.

 

Dave, who makes/sells them? Thanks in advance! ZoranC

 

http://www.cervinis.com/ cost is about $500 plus shipping and paint

 

Thanks! They look nice, but I am lil concerned about scoops taking in water when raining. Any thoughts/experiences?

Thanks again!

not true. i have the exact same hood. (439 plus shipping btw).
the stock hood is aluminum and weighs a hair over 20 lbs. the cervini's hood is fiberglass and weighs twice as much. I know too, i swapped hoods myself, it was a PITA! Weights a little over 40 lbs. You couldn't tell the extra weight when you open the hood and it doesn't lift and open the rest of the way by itself like the stock hood, and you have to push it open all the way for it to stay?

here's afew more shots of it




my custom made billet inserts so it matches the grilles




o yeah, zoran,

if you have a stock airbox, no need to worry at all. You can wash your engine full blast with a hose and no need to worry, so a little rain water won't hurt. If you have a conical filter intake, just get a JL outerwears prefilter. Its water resistant, so it won't suck any up. I don't have one yet though, and i'm having no troubles. When i wash the trucka nd water shoots in, and i open the hood, i can see exactly where the water shoots out and its not near the filter

 

#356, its not just air intake I worry about, it is whole that area. I don't like idea of water getting on anything inside, especially on metal (fear of rust and agressive deposits that come along with rain in polluted areas like Los Angeles, all long term) or even worse on any electrical components. Water will get in more nooks and crannies faster and farther when you are driving in rain at 80mph for an hour than during car wash.

Which now, that I think of it, I might be able to resolve easily. Considering that I live in Southern California we have rain only small part of the year. I can get hood with front intakes and make "plug" that I can use to fast close openings on those ocassions when it starts raining, and rest of the year leave it open and benefit from better air circulation. Hmmmm, that is an idea for a product I thereby claim this as original idea and patent, manufacturers back off unless you pay me license fees

So, I am still split between cowl induction hood and front intake hood. I am also curious is there a hood that combines both (again, if this is an orginal idea I claim all rights on it ) and looks good. Are you aware of any?

Thanks!

only hood that i'm aware of that is cowl and ram air look is Sal (LightningTuner) and his is custom made

I wish cervini's made this hood for the current design f150's
Its a combo ram air/1" rise cowl induction. but its only for the previous gen. f150's




anyway, i am still saying don't be worried about rain coming in. They've sold a ton of these hoods, and not once have i heard of a problem from anybody online who has one, and this is a really popular hood.
Your electrical stuff is mostly on the side and back part of the engine bay. THe ram air scoops dump off right over the radiator shroud. You'd think from the pics it dumps back further onto the engine, but it really doesn't. And when i wash my engine bay, i wash it GOOD. LoL. I only cover the alternator and open air filter. I put the sprayer nozzle on the hose and spray everything full blast. then i spray everything with diluted simple green, let it sit, then rinse it off really good, then dry it with the leaf blower while the engine is running. Then i hit everything with vinylex for a nice low gloss shine. I do this every month in the summer and spring during show season. If that doesn't hurt anything, and i wash everything under there, electrical stuff and all, a little rain water coming in those two small scoops isn't gonna do anything. The mesh screens that come with the hood will block alot of it also. I mean, how often will you be driving at 80 mph when its an absolute downpour. If its raining that hard where its gonna soak your engine that bad, i wouldn't be driving that fast

 

Considering I can not have both which one of them (cowl vs scoop) would be more beneficial from functional standpoint (ignore personal preferences about looks)?

Its just me, I hate idea of water in there.

I agree with you on need to drive in accord to conditions on the road, I used value of 80 just to illustrate my point.

Thanks again!

If you are that worried about rain, i'd say a cowl hood cuz it will let less air in and less rain.
otherwise, i would say a ram air hood cuz there is a more direct path for the air to come in and cool everything down a little.

the only functional hood out there though that i know of, that actually hook up to your air box are the keystone hood like outnumbered has (but it won't work with the s/c engines airbox) or the 2 proglass hoods. Either the shaker hood, or the cowl hood that lucky is getting. The shaker probably lets more air into the filter cuz its scoop is right there sticking out the front, but the cowl has a little more function with the 2 gauges in the hood and the functionality of it. The shaker will only work with the s/c engines.
if you want, i can post some pics of the shaker, and some pics of the bottom of the hood that illustrates how it works and channles the air

 

Question was more which one (cowl vs scoop) ends up giving lowest temperatures overall in engine area. Scoop lets more air in, while cowl lets more air out. Which one of these creates better airflow and lowest temperatures in the end?

Also, I have not changed my air intake to collect air from engine area instead of fender, and I am not planning to do that, so I am not interested in which one gives best air to supercharger. I am just interested in better airflow for all of engine compartment because I live in Southern California and I want to do everything possible to improve conditions under which this truck will be working.

Thanks in advance!

ZoranC,

In my opinion a ram-air with open slots in the front will ventilate your engine compartment best over all the other choices.

Check this link for engine compartment temperatures

 

nope. They both let air in. thats why its called ram AIR and cowl INDUCTION cuz they both suck air into the engine bay. If its cooling you want, the ram air is definately the better choice, cuz the air blows right in and over the top of the engine and stuff.

the reason its cowl induction and now cowl vent if thats your next question is because with the back of the hood raised up, it creates a low pressure area, and the air gets sucked in. A good example is your rear slider window if you have one. If you open that up when you are driving, put your hand infront of the window. You'll feel the air blowing into the cab, and not being sucked out. Its the same pricipal with the cowl induction hoods. And if you don't have a tonneau cover, and there are leaves in your bed, they'll sometimes blow into the cab throught the rear window

 

chesterc, that is some interesting info, thanks for your effort.

However, I feel it will not apply to me. He was measuring temperatures in thin layer directly under the hood. I do expect those temperatures to be low with ram air because that is directly in the path of the air that is being forced in.

What I am really interested in is overall temperatures, not just ones at that thin layer. Temperatures accross all heights if engines. See, in my layman inexperienced mind this is what might be going on:

With ram air you are cooling one relatively thin layer. Hot air that is below that thin layer might not even get chance to rise up due to pressure of air that is being rammed. That might cause temperatures in lower levels (and that is where engine is) to rise overall or in some pockets, or might cause turbulence that will create heat where engineers did not expect it. So, by going with ram air you might be doing good to your air intake (assuming it is sucking air from that area) but you might be hurting everything else.

With cowl you are creating an airflow that I suspect is better than one created by ram because it should be cooling across all height levels, not just one. So, what I was trying to find out with my questions is are my assumptions (that cowl would be overall better to all components of engine compartment) correct.

Thanks again!
