ok, I was watching cars on tv. specifically the viper Vs. the Z06. maybe y'all saw it. anyway, this is an idea I've been working up for the last year. I've finally decided to buy a new hood because I want to cut vents in like gig's money ride, and I also wanna get a nice scoop. I'm not a body work expert but ideally I'd like it to be a negative scoop, like the marenello or modena. you know, sinks in instead of rises above? So I was looking at clearence over the valve cover under the hood and I think I can do it. heres the thought. make a small Y shaped box that seals up with the hood. In the back of the Y, put 2 cylander filters. this is exactly like they do it on the viper and corvette. then the stem of the "Y" feeds over the valve cover and into the TB. heres the hang-up. Ideally I'd like to design a new intake manifold to place the TB on the side instead of on top. since that really isnt an option I thought of this instead. make a wedge out of acrylic. at the right angle, I could fit it between the TB and intake manifold. this would angle the TB forward and I hope provide a smoother inlet. Maybe even get a residual benefit from a spacer. (ie; intake air speed. So now I want feedback, do you think I have enough room to do it? how might you work the TB situation? will Gig travel to Texas and do my bodywork for me?

Got any pics of the vette or viper setup so it's a little clearer? I have a rough idea but I'm a little sketchy.

I'm guessing the reason for angling the tb is so you don't have a 90 degree bend in the intake tube and not for any fitment issues right? The tightest clearance between the hood and the engine is at the front edge of the valve cover. The closer to the firewall you go the more room you have. The spacer can work but I wouldn't use acrilic. I made spacers before and I used phenolic, it's much better suited for being put in an engine bay.

You'll have to be going very fast to get any real benefit from ramming the air but you will however get the nice cool air of a cai without worrying about sucking up a small lake into your motor so it sounds pretty good.

Oh, and sorry but I'm thinking the chances aren't very good that I'll be bodyworking anyone's car but mine anytime soon.

you're a bastard! I saw the job you did with the vents and triangles. you better come down here and help me out! Let me look for the ram-air pic, I think I know a site that will have one. In any case, the point of the wedge is indeed to eliminate the bend. I want the air flowing in as smoothly as possible. I dont really think I will be getting a huge boost from the "ram", but I do want nice cool air without the puddle sucker. I am also extremely bored and need a new project.

back in a flash after I find a pic.

 

[TXFO]

having trouble with imagestation but here is a drawing I made of my idea. its pretty similar to the viper. the difference is that in the viper the engine is sideways so its a straight shot without having to go over anything.

Could you use the charge tube from an Escort RS? It is mostly the same idea you have. With a few mods, you'd be there and have a Ford part to boot.

how soon you plan on doing this? i'm planning on having a cf hood within a month or two.

 

[Jimmy]

That's one of 2 ideas that I would love to try out.

The other is to basically copy the WRX setup as much as possible, because the old (from a couple of years ago) hood scoop on the WRX is simply gorgeous.

I'm long on ideas and not so long on funds, so right now Im in the planning stage. If you are suggesting I buy your old hood, then I say

If your not then

. Right now this weekend I am trying to fab up a box for the filters. just a little prototype out of cardboard or something so I can test fitment and how to attatch it securely. I'd like to have this done within a few months or so.

What is the RS charge tube you speak of? can you find a pic or something so I can see what you mean? it would be awesome if I could get something pre-fab'd that only needs a slight modification.

You want the intake where the highest air pressure is.
The best place for the intake would be the bottom of the front bumper....at least on a Taurus. I'd do what this guy did before I spend money on a ram air set up that doesn't work.

Very cool link. I like the way that guy thinks.

but if I route to the front bumper then it is no longer a ram air. now its just an AEM puddlesucker. The point of a ram air is ease of air travel and at high speeds, mild forced induction. ok, what about this. Even though the recessed scoop looks super-cool, I make a mustang style scoop near the front of the hood where the big hole in the support structure is. Make a kind of air dam/spoiler to catch air and pull it in.I can still recess it but make a kind of "catch" to pull it in.
I went to the car and was working on some ICE related stuff. While I was there I did some figuring. the SPI engine is offset to the passenger side. So now I have basically eliminated the problem with valve cover to hood clearence. My new plan is to come around the cover driver's side and then straight to the hood. that should set the scoop dead center. I know it kinda kills a ram air thing but I doubt I was ever going to see a "ram-air" effect. at least its a kick ass CAI. Any more thoughts?

The Escort RS charge tube goes from the turbo to the intake. It runs right across the middle of the valve cover. It is also oval or flattened for hood clearance. Try Ebay UK and you should be able to find one. It says Ford right on it and should be a decent part that just needs a few mods to do what you want.

like gig's money ride

 

[Gigaherz]

I like the original naca scoop idea but I think any other scoop way up front won't look so good.

here is a pic of what waterboy is talking about btw.

 

[TXFO]

yeah, that tube looks real good, I like that its bent to the right also. the offset of the engine calls for a bend. Maybe I can use that instead of going around. the benefit is that the TB is so far back from the VC that its only a modest curve. and If I make adifferent angle spacer tehn its even better. Gig, I checked the location of the first big support structure hole and it is actually not that close to the front. its a reasonable distance back and I think it would fine there. I am extremely concerened with the cosmetic effect of it all. performance is great but I dont want it to look stupid. When I get my new hood Im gonna cut the vents in and then position the proto for the new scoop to see how it all looks together. I like that big cut in the hood, I think it would make a nice template for the design of the box. it has a nice diamond like shape that is perfect for the placement of the 2 cylander filters, plus the framework will really help it seal up tight. The only thing I dont like is that puts the box right over the exhaust manifold. I'm gonna have to make the bottom of the box really thick to try and sheild it as best I can. ok, off to ebay UK to look for that charge tube thingy.

wanted to add, I am still hoping to make it a recessed scoop. I dont particularly like the idea of a positive scoop. but maybe I can elevate the angle of the whole center part of the hood to allow for catch type design.

You have probably the best car-related names EVER.

I second the lower bumper idea (I did it to my 93 Taurus, and it made a difference). The down side is that its more prone to weather-related problems...Mine actually got clogged with slush/snow once.

 

[TXFO]

ok, good news and bad sort of. I found someone on ebay uk who is parting a turbo escort. She said to make her an offer. how much is that piece worth? I dont wanna come off all low-ball but I dont wanna screw myself either. and is charge tube the official name for it?

 

[StickShifter]

Just my thoughts...
Viper has two separate intake tubes, two filters, tbs, etc...No 'Y' ...Just some technical info there; no big deal...A dual tb Focus would be pretty cool but would require a custom manifold to be most effective...
Highest air pressure, and best place to get force-fed from without sucking up puddles is the cowl...Cowl-induction...Duh...Thats why that works...You could hide the filter in the cowl, so it wouldnt be apparent you were sucking high-pressure cool air from there...Umm not sure what else...
Im not trying to be a dick, and I hope I didnt insult anyone with my post...I was just trying to keep it short and sweet...If anyone needs further explanations of anything, let me know and Ill elaborate further...
Im just trying to help you out on your project, and give you some more options...Good luck...

 

[TXFO]

no dont worry man, I appreciate all constructive input. I thought about the placement and the problem with the front bumper and such is that the fans block it. and too low is no good for me. here is a pic of the viper set up for reference.

I was thinking to offer 25$ for the charge tube? any thought on that?

 

[TXFO]

just noticed you said cowl. how do you get positive air pressure from the cowl?

 

[StickShifter]

When the passing air hits the windshield, it builds up high pressure at the base of the windshield...At the cowl...Probably not as high as at the bumper, but less likely to suck in a puddle...
