Roush intake question

[what's that?]

If any one has information, instructions or spare parts for the 94/95 Roush twin plenum intake, please let me know.

I am going to use the intake on a 347 in my Cobra.

I need to find a hood for it. I know the Roush hoods are almost impossible to find, but I doubt that Roush made them in house, so does any one know who made them? There is probably a mold sitting unused somewhere.

If that is a dead end, are there any good ways to fit it under a stock hood. Please don't say Cobra R, I don't want to look like every other Cobra wannabe, that is why I bought a real Cobra. Would a tubular K member with 1" engine setback and a set of drop mounts get me close?

(by the way, so no one gets confused, 94/95 Cobra's used the same hood as the GT/V6 cars)

Now for my contribution. No one seems to know what one of these intakes will do for power with the exception that Roush had a supercharged version that made 632hp I believe.

I found several posts on the Corral about a guy who had a Roush intake on a 347 with AFR 185 heads and made 408 rwhp. That's pretty impressive for a 347, even if the dyno was reading 10% high. What is more impressive is that the computer was improperly tuned, and the stock rev limiter was not defeated, so that 408 was recorded just as the rev limiter was ending the party.

Mine is going to be built to rev, and I won't give up untill I see 400 at the wheels, but I'm shooting for 450.

Hey what's that? - welcome to the site

You lay out some hard-hitting questions right from the start. I like that Unfortunately, I don't have squat for answers. There are a couple of guys here that will be able to answer a few of these questions I am sure. SMOKE is our resident 94-98 encyclopedia of knowledge. He remembers crap that no human should keep in their brain

I do know there has been some talk of the Roush hood, and nobody seems to know where to find that style. Wings West is currently making some of the Roush 94-98 body parts, so you may want to start there.

As for your K-member thought, I don't know anyone that is currently doing that kind of setup off the shelf. I think Griggs had a setup that did a 3/4" move forward on the front wheels, which may allow for a drop of the motor mounts. Again, not sure, just typing.

Good luck on your quest. Hopefully someone will drop some info in here soon.

I'm talking about the 94/95 Roush. They had a special cowl induction hood that fit their intake manifold.

A Cobra wannabe is a GT or V6 with a reproduction Cobra front bumper, Cobra R hood, Cobra R wheels with puny brakes inside them, and every cobra badge they can buy, plus stickers.

On the 94/95 cars you can easily tell because the Cobra's had a special trunk lid without the third brake light, and an LED brake light in the spoiler.

Lots of people do this, and they mix and match parts untill it is obvious that it's fake. You will see Cobra R hoods with 96 tail lights, 96-98 Cobra hoods with 94/95 tail lights, snake emblems in the grill (never standard) and 96-98 "Cobra" rear bumpers with 94/95 tail lights.

The regular 94/95 Cobra is pretty subtle, the front bumper, wheels and brakes are the most obvious differences, and I think that looks a lot better than some mixed up Cobra R look alike. Now If I add a Cobra R hood, I'll look almost like all of the wannabe's.

Yours is not a wannabe because it came with the hood. I does not have fake Cobra badging, you didn't mix and match years, it's an OEM part, and it has the power and brakes to back up the look.

Is this the hood? http://www.fnsweet.com/docs/brochure_full.jpg

That's the one. If I had known how hard they are to find, I might have forked out the cash for the whole kit, but then again, I didn't have my Cobra or the money to buy that kit back then.

Here is another good roush intake question:

What is better a set of Roush CNC ported GT40's or the new Roush 200's?

I'm sure that Roush will say the 200's because they probably don't make the CNC heads any more, but What is the real story?

Ok I'll try to live up to the Old School rep ... thanks for the vote of confidence Kev.

The question about the hood has come up before several times. 1. 2. 3.
REF: intake

Conventional answer is the Cobra R or any elevated hood for the cowl induction. But, I think you could do it with the Heat Extractor hood ... the material towards the back could worked to allow for some airflow similar to the ROUSH Cowl Hood. That's just an option I keep reminding folks who don't want the Cobra R hood.

Now the brochure advertises ...

They claimed it added "47HP to your stock 5.0"! With GT-40 heads, up to 99HP, and with Roush CNC-ported GT-40 heads, up to a 120HP gain!

... so I'd say the intake flows well with any prepped heads. I don't recall a comparision between the ROUSH 200s and their CNC'ed heads. Sorry. But, the best answer would come from BDR {BigDaddyRoush}. PM him if he doesn't chime in, he could probably give you a better idea of the comparison.

Hope this helps.

PM NashvilleGirl, she has the intake and is getting ready to put one on her SN95, she also has a contact at Roush.

[SMOKE]

Thanks StarDriver ... thanks who else I was going to recommend, forgot the screen name.

[what's that?]

I have seen the heat extractor hoods like the Saleen, Harwood, Ebay specials and I think Griggs or Steeda makes one, but I don't like the look, and the vents suck air out of the engine compartment, I would rather find a way to ram air in to the air box.

I'll have to talk to NashvilleGirl because I think the real answers are buried inside Roush and I will need a leak.

I have been lurking for a while and searching for all of the info that I can find, but there just are not that many people with these intakes. There was the guy on the Corral, but he sold his, one guy on GT40s.com who has not installed it yet, NashvilleGirl who has not installed hers yet, another guy on the corall with the intake on a supercharged fox, BDR, and the guy I bought mine from, but he is trying to put it on a stroked 351. So I only know of 2 people currently running the intake, one has the application completly different and BDR is trying to sell his.

Also, on the heads, I thought that Roush was using AFR's on their crate motors, but I read one of the PDF's and it says Roush aluminum CNC'd heads with 185cc intake ports. What do they start with, A windsor light, GT40? Or is this marketing speech for AFR 185's?

Right now I'm leaning towards the AFR 205's. It looks like they are the easiest way to get to 300cfm, and their quality control seems to be good. Also the raised exhaust port isn't so high that it will need a new set of headers.

[Star Driver]

Check out Mustang and Fast Fords Tech Guide magazine, it has a yellow LX coupe on the front. They have an article on 5.0 head swaps and test 4 cylinder heads including the AFR head, hope this helps.

[what's that?]

I know that AFR's are good stuff, but that does not tell me what roush is using, or if Roush CNC heads are their old GT40's.

I'm asking because I can either buy AFR's that I know flow well and are very consistent because they are CNC'd, or I can try to buy a head that I think has what it takes, and if it does not, I'll have to buy new heads or spend lots of money to get them ported by a pro.

I just looked at TEA and their twisted wedge 185 looks interesting and the 205 looks like more than I need, but the price is pretty good.

'Were' using ... GT40s. Good luck searching it will be hard, like you mentioned, not a lot of people ran the application.

[what's that?]

I know that they had CNC ported GT40's back in the day, but what are they using on their new crate motors? They say it's a 185cc CNC ported aluminum head. I thought they were AFR's, but I could be wrong, and if the Roush 200 iron is so good, why aren't they using that?

My gut feeling is that the World Roush heads are just a bit better than the World windsor heads that they are replacing, which is to say that they are a decent head, but not the greatest. I think that Roush may have worked a deal with AFR to re-brand their heads Roush, like they did with the Steeda TriAx shifter. I have never asked, but I bet it would be pretty hard to get Roush to CNC a set of GT40's. I guess I'll put that on my list of questions to ask when I do contact them.

What ever it is, I think I might go another way. Those TEA 185's look killer, and I think I have found a rocker setup that will give me good high rpm stability and possibly fit under the intake.

I'll let you know how it works out.

Super Ford Feb. 1998 has a 4 page article where Roush installed it on a supercharged Fox. They were using ported High Ports on a 347. The article also talks a bit about the hoods. "

It says the 95 hood has a subtle 3/4" rise and they can get by with a 1" rise. On a Fox they say there not sure but probably 2" is needed. I set the intake on my 95vert longblock and closed the hood and it seemed to fit but I didn't have any gaskets installed. I don't know if the convertible motor mounts are not as tall or what.

There is a Car and Driver issue in 1996 where one of their staff installs it on his Mustang.

John,
If you have those articles on hand ..... scanning them and emailing them to KEV so he could host them on the site would help to benefit us all.
I remember both articles but lost a lof of my literature in several moves.

[NashvilleGirl]

John, I'd love to have copies of those articles again. Mine were taken. The intake I bought from you is going on the car next week. 3rd Shift Performance here in Nashville is doing it, since there's no way I could tackle this on my own. I work down your way now. Drop me a PM and let me know if I could pick up those copies from you.

Thanks!
Lisa

[what's that?]

Some activity, that's great.

I have been talking to a guy with an intake on his car. He had some information about the hoods. I am trying to track down the mold, if I can find it, I'll let every one know.

The biggest piece of information about the intake that I have found is that you have to remove the upper and middle intake to set valve lash. I need the best low maintenence high rpm valve train possible. Anything that can stretch my lash adjustment intervals will be a big help. Anything but hydraulic lifters, I want it to rev.

Please let me know of any information that you gather.

[kbconv]

NashvilleGirl,

I thought that might have been you. I have a copy of the install manual you can copy and a copy of the Super Ford article. Do you have access to a scanner so we could get this info posted?

Send me an email with your phone number. Also, which injector/computer setup are you gonna use. The Car and Driver article would be a good one as a "novice" installs one in his garage. It may have a tip or two. It was a 1996 issue I think. I can't find mine right now.

Thanks, John

Also, on the hood. I think H.O.Fibertrends would be a good place to start since they seem to have done some work with Ford and may know the story on that hood.

Also, I just found the Car and Driver issue (Yeah!!!). February 1997, page 117-121. Anyone have any Mustang mags from 1995 to 1998? I bet they have some info.
