More Functional: SS or Cowl Hood

I think a long with many others that the SS hood is definetly cooler looking but with the open element on the TBI which hood is more functional on getting colder air to the filter. Or do both of these hoods see the same performance gains.

the only reason people put the cowl hood on their car is to get engine clearance. with carb modifications and stuff like that, the air filter sits too high, and that's why they need the cowl.

the ss hood on the other hand has that little hole that i would guess allows alot more air into the engine compartment. and of course it has the bulge of the cowl hood as well.

The SS Hood is not functional unless you do some hacking and custom make a mesh grille insert.

The ASCD SS Hood comes with a grill.....you don't have to cut anything at all. The only reason it's not functional is because it doesn't come with an airbox.....if it had an air box...it would be fully functional. With no airbox......it really really cool's the whole engine compartment down though....I dropped like 15 degree's since I've had mine on.....

Ah sweet then. I saw a guys car that had a big block hood and he had to hack out the middle and make a grille, so i figured it was the same with the SS.. nice!

So who makes an air box for the SS hood? or what do you need to do to make one? So if an aibox is made for the SS hood it would be more functional than the cowl hood?

I wish I knew.......I have no idea how to make one...or if any company makes the air boxes for the SS hood. Right where the ram air cut out starts on the hood.....it's like right on top of the plenum....so...it looks like it would be impossible to make a ram air box.......but....I'm not sure. If you had an airbox.....I would have to say it would be much more functional then a cowl hood.....

Well I still like the hood even though it doesnt have an air box. It will get colder and more air to the filter than the stock hood and it does look better than the cowl hood.

Did you really see any performance gains other than running a little cooler from it ? You dont have TBI or Carb setup so I guess with that type of setup the SS hood would have more function?

Well...I noticed a little more quicker of a throttle response....cold dense air really get's into your engine compartment....other then that....not much of performance gains.....the only reason I got the SS hood is because it looks soooo aggressive.....and noone around here has it...

Yeah it is a very mean looking hood, it fits our cars lines perfectly. When I get some extra cash I will get one as opposed to the cowl hood. I think having this hood will help out a lot more having TBI rather than TPI. By having the hood it can almost give me a ram air affect.

Exactly....I mean...the cowl hoods look great on our cars....don't get me wrong....but like everyone around here has them.....whether is's a truck...or an old street rod....I just picked the SS because nobody had it....and it still has the genuine camaro look...!!

Whoever said a cowl hood isn't functional is wrong, the air that goes over it, gets sucked down into the back part of it, if there is an opening, which most have.

I would rather have an SS hood though.

I know that I cowl hood is functional but which is more functional the cowl or the SS hood with a TBI set up. I would love to have the SS hood but if it doesn't offer any performance why bother.....but I would still buy it because it looks bad ***.

The back of the SS hood is not open on the cowl like a cowl induction hood is, but you can cut the back out. This would give you an opening on the front (the factory opening) AND an opening on the back of the hood. This is what I did with my SS hood. Thus, with some very minor work on your own, an SS hood would be twice as effective for a TBI or carb setup.

The SS hoods scoops is still pretty small, and because of how the air flows over the car actually does very little for creating any kind of "Ram Air" effect. If you rig up some sort of seal to hook it up to your air filter, you'll be getting a good cold/fresh air effect more than anything, and thats still a good thing.

From what I've heard/read, a cowl hood actually does force air into the engine compartment at speed because air pressure builds quite a bit at the base of the windsheild for areodynamic reasons. You may notice some large and semi trucks, especially older internationals, have a small cowl opening just in front of the windsheild for this very reason.

But really, lets all be honest, we do it for looks mostly, or if you need the room which most 3rdGen cars with anything taller than a performer intake usually need. Thats why I wanted one! (never got it though)

ss hood air box?

now i havent seen one of these hoods in person so i am not sure on this one but to me by the looks of it and it was said earlier in the thread that the "scoop" looks to be ontop of the plenum? right. well what if u used an lt1 SS air box as a start and kinda form your own box out of either sheet metal or make it wooden and the glass it? i plan on getting the hood and making the hood work as if it was intended for a forced air system. but like i said if i had the hood i could help out more

I'd really like to know if someone has done this or not....it looks impossible to me....it would have to be a really thin box...because there isn't much room at all....if you guys want pictures of the SS hood...(inside, close-ups) let me know....maybe we can come up with something......

Also, in summit or jegs I've seen something that might work. The pro street guys who run the big *** scoop hoods have this pan thing with foam rubber around it to snug up to those hoods to make them functionl. Maybe it could be adapted for a TBI car?? I'm gonna flip though a catalog and see if I can't find on, if I can, I'll dig it up in the online catalog and post a link.

wOOt! Found it!

http://www.jegs.com/cgi-bin/ncommerc...03&prmenbr=361

I'm sure the size isn't quite ideal... but it could be made to work I'm sure.

Whatcha guys thing? You'd probably need kinda a small filter... a K+N Extreme flow lid would be idea... or maybe somone could just make one out of sheet metal, and buy the replacement foam kit and custom make one. Or, take an air cleaner base, put that foam on it.... or use an Extreme flow lid and stick the foam to the underside of the hood, and have it come down on top of the filter and seal it. Heck, you could even take the stock "Garbage can," , throw a lid on the small filter inside, and use the space around the edge to mount the foam and have it go up to the hood, isolating the filter from underhood air completely, only able to pull through the scoop up top.

Just throwing out some ideas, jump on in guys and tell me if I'm crazy/retarded but I say it could be done.

That is a damn good idea. Would their be a problem with water getting into the engine compartment? What did you use to cut the hood?

actually the cowl hood is just as funcual, at the higher speeds the wind comes over the hood and hits the base of the windshield and spins around, but with the cowl hoow it lets that air go into the engine bay, keeping colder more dence air in the engine bay.

but also at the higher speeds the SS hood's scoop is not as high as it should be to be able to catch the air that is going over it so it is not as good at HIGHER speeds, but for normal driving like through town they both are good ways of induction.

Any further word on making the SS Hood functional? If I remember right, the 4th Gen SS Hood directs air flow back toward the front of the hood where it has an opening to mate with the airbox. Some pics of the bottom of the SS Hood for 3rd Gens would be nice.
